Arnie Imholte A good friend. A great agronomist. A fantastic person.

2017 will go down as one of the toughest years in history in Southeastern Wisconsin. From heavy cold spring rains, summer drought, a roller coaster of cold temperatures in August and hot temperatures in September-it was one for the books and one that tested our resolve to be among the 2% of people in the world who farm. There is no doubt that we are a tough, intelligent, and resilient group of people that love what we do and realize that keeping informed of agricultural trends will help us persevere during years like 2017. In fact, that is the goal of this book. We put 42 seed plots in this spring in order to test our products against competitor’s products to give you more local information, research, and data than ever before so that you can make informed decisions for your operation based on plots “in your backyard.” “Right product-Right Acre” is more than a motto in Pioneer. It is knowing our products so well that we are able to help you determine which product will do best on a specific piece of land so that you are able to get the best yield no matter what Mother Nature throws at us. We know that with quality-local information like you will find in this book--with these plots and the data they offer, we are helping to take the guess work out of seed placement on your land and return command of information and profitability to you, the grower. As we look forward to 2018, our goal is to put in even more plots next year. If you are interested in having a plot on your land, please contact us and we can plan the plot together this winter.

2017

Making the Right Choices, More Often On-farm testing is the best way to evaluate product performance. Replicating genetic plot sets across Wisconsin allows us to increase our comparison numbers and confidence that measured yield differences are real and repeatable. If looking at just one comparison, the odds of the winning hybrid or variety from that comparison winning in another comparison is not much better than a coin flip. As the number of comparisons goes up, confidence that the winning hybrid or variety will win in future comparisons also goes up. A large testing network with high comparison numbers among products tested across different years, on-farm agronomic practices, and weather patterns helps DuPont® Pioneer® evaluate product performance and helps growers reduce risk by picking products tested on a national and local level.

Yield data, agronomic data, and visual observations by Pioneer Sales Representatives, Account Managers, and Agronomists are collected to understand how products may perform under different management practices. Data collected at each location include: • Row Spacing • Planting Date • Harvest Date • Planting Rate • Yield • Previous Crop • Moisture • Irrigation • Test Weight • Tillage

Example: If a hybrid wins one single comparison by 3 bu./A, there is a 51% chance of that hybrid winning the next comparison. If the same hybrid wins by an average of 3 bu./A across 30 comparisons, there is an 85% chance that hybrid will win the next comparison.

Corn Stalk Quality Many different stresses to corn plants can lower stalk quality, with the result that stalk problems occur in some fields each year throughout North America. Drought stress, reduced sunlight, insect and disease pressure, and hail damage are stresses that can result in poor stalk quality. Even good growing conditions can lead to stalk problems when followed by a less favorable environment. Cropping history, soil fertility, hybrid genetics and micro-environment effects can heighten the problem in certain fields. Growers should monitor their fields as harvest approaches to identify stalk quality problems, and if necessary, prepare to harvest before field losses occur.

Stalk Rots Often Begin as Root Rots Stalk-rotting fungi inhabit the soil in the root zone of corn plants, surviving on discarded cells and nutrients excreted by the roots. They are prevented from invading the roots and stalk by metabolites produced in the plant. Though unable to overcome healthy living tissue, these opportunistic fungi rapidly invade weakened and dying roots as the plant redirects carbohydrates from the roots Root rot beginning in the to kernels. After the roots are basal stalk region. colonized, the infection spreads to the stalk (Dodd, 1983).

Photosynthesis and Carbohydrate Translocation Through photosynthesis, leaves of corn plant capture sunlight and carbon dioxide (CO2) to produce sugars (photosynthates), which are directed to the actively growing organs of the plant. Early in plant development, sugars move to the roots, where they are converted to structural carbohydrates and proteins. As plants continue to grow, sugars are directed to the stalk for temporary storage.

As vascular tissues in the plant become plugged by fungal mycelial growth, water supply to the plant becomes restricted. Wilting and premature death of the plant eventually follows. External discoloration of the lower stalk becomes evident as deterioration of the inner stalk tissue progresses. The structural integrity of the stalk is diminished by this decay, and the plant is susceptible to lodging. Storms and high winds provide the forces needed to topple the weakened stalks.

Following pollination, kernel development places a great demand on the plant for carbohydrates. When the demands of the developing kernels exceed the supply produced by the leaves, stalk and root storage reserves are tapped.

The Growing Environment

Environmental stresses, such as drought and low available sunlight, decrease photosynthate production and force plants to extract even more stalk carbohydrates, which preserves grain fill rates at the expense of the stalk. Disease lesions, insect feeding and hail damage also limit photosynthate production by reducing the functional leaf area of the plant.

Drought Stress - The decrease in photosynthetic rates due to drought stress has been well documented in research studies. Water relations within the plant and CO2 and O2 exchange are directly affected. In addition, if leaf rolling occurs during drought, the effective leaf surface for collection of sunlight is reduced.

Almost any stress applied to the plant will reduce photosynthesis and resultant sugar production in the leaves.

As carbohydrates stored in the roots and stalk are mobilized to the ear, these structures begin to decline and soon lose their resistance to soil-borne pathogens. High temperatures increase the rate at which the fungi invade and colonize the plant. Though pathogens play a key role in stalk rot development, it is primarily the inability of the plant to provide sufficient photosynthates to the developing ear that initiates the process.

In research studies that withheld water from plants beginning at the mid-grain-fill stage, photosynthesis was eventually shut down (Westgate and Boyer, 1985). Subsequent grain development depended entirely on stalk carbohydrate reserves. Reduced Sunlight - Photosynthesis is most efficient in full sunlight. Studies show that the rate of photosynthesis increases directly with intensity of sunlight. In fact, photosynthesis rates are reduced more than 50% on an overcast day compared to a day with bright sunshine (Moss et. al., 1960). Prolonged cloudy conditions during ear fill often result in severely depleted stalk reserves. Reduction of Leaf Area - Any reduction in leaf area will limit total photosynthesis. Leaf area may be reduced due to hail, frost, disease lesions, insect feeding or mechanical injury. Whenever functional leaf area is reduced prior to completion of ear fill, stalks will be weakened. Early Favorable Conditions Followed by Stress - If favorable conditions exist when the number of kernels per ear is being established (V10 to V17), the eventual demand for photosynthates will be large. Each potential kernel represents an additional requirement for translocatable sugars from the plant. If stress conditions develop during ear fill that render the plant unable to produce enough sugars, stalks will suffer.

Other Effects

Research has demonstrated that the number of kernels per ear on stalk-rotted plants is often greater than that of adjacent healthy plants (Table 1). The additional demand for carbohydrates by larger ears often results in greater depletion of the stalk, leading to eventual stalk rot.

Micro-Environments - Oftentimes, even small differences between fields or between areas in the same field can determine whether corn stands or lodges. Differences in soil fertility, soil moisture, plant-to-plant spacing, insect feeding or wind gusts can push plants past the lodging threshold. These effects are difficult to predict; however, scouting in the fall can identify problem fields, and early harvest can reduce field losses.

Reducing Harvest Losses Due to Stalk Lodging

* From Dodd, 1980. ** Significant at the .001 prob. level.

Careful scouting and harvesting fields according to crop condition can help prevent field losses due to low stalk quality. Corn loss potential should be weighed just as heavily as grain moisture in deciding which fields to harvest first. Scouting fields approximately two to three weeks prior to the expected harvest date can identify fields with weak stalks predisposed to lodging. Fields with high lodging potential should be slated for early harvest. Weak stalks can be detected by pinching the stalk at the first or second elongated internode above the ground. If the stalk collapses, advanced stages of stalk rot are indicated. Another technique is to push the plant sideways 15 to 20 inches at ear level. If the stalk crimps near the base or fails to return to the vertical position, stalk rot is Collapsed corn stalk. indicated. Check 20 plants in five areas of the field. If more than 10 to 15% of the stalks are rotted, that field should be considered for early harvest.

Soil Fertility Research studies have documented that soil fertility has a profound effect on stalk quality. Most notable are studies which show that a combination of high nitrogen and low potassium can severely reduce stalk quality. Researchers suggest that yearly applications of N and K (actual N, K as K2O) should be approximately at the ratio of 1 to 1 for favorable balance in the corn plant and to reduce the risk of stalk rots and stalk breakage. High nitrogen (N) is associated with greater kernel number, which increases the demand for carbohydrates to the ear. Higher N also aids the movement of these carbohydrates out of the stalk and into the ear by increasing the rate of translocation within the plant. The role of potassium (K) in preventing premature plant death has long been established. Potassium functions in the building of leaf and stalk tissue, as well as regulating water movement within the plant. Increases in K have been associated with increased photosynthetic rate.

Hybrid Differences / Foliar Fungicide Applications

DuPont Pioneer Research Emphasizes Stalk Quality

Carbohydrate Partitioning - Some hybrids naturally partition more carbohydrates to the stalk. Though useful in a poor stalk quality year, that trait may limit yield potential in a more normal environment. As hybrids are developed, researchers must be careful to select those with highest harvestable yield potential across many years and environments. Too much emphasis on stalk quality alone could result in lower yield potential most years. Many carefully selected hybrids with very good stalk quality may appear inadequate during a one-year-inten stalk-lodging event.

DuPont Pioneer corn breeders and plant pathologists use aggressive techniques to weed out hybrids with poor stalk quality, including manual and mechanical push tests that mimic the forces of wind on corn plants. In addition, plants are inoculated with stalk rot organisms where appropriate to help ensure that susceptible genotypes do not escape detection. Plant pathologists monitor disease incidence and assist breeders in their efforts to inoculate, screen and characterize products. Research trials conducted by corn breeders are designed to measure product performance for all important traits across a wide range of growing conditions.

Leaf Disease Resistance - Hybrids prone to leaf diseases may lose significant leaf area, weakening the stalks. For this reason, foliar fungicide applications may reduce stalk lodging in years with high levels of fungal leaf diseases. DuPont Pioneer rates its hybrids for resistance to major leaf diseases to aid customers in their decisions about fungicide applications.

Pioneer IMPACTTM plots further test product performance, including characterization of stalk quality, thus determining proper placement of new product releases. Pioneer uses information from both breeder and IMPACT plots to develop stalk lodging ratings for all its hybrids to aid customers in selecting appropriate hybrids for their fields.

Stalk Rot Resistance - Susceptibility to specific stalk rot pathogens also increases the stalk-lodging risk. Pioneer provides hybrid ratings for resistance to major stalk rots.

Maximizing the Value of Foliar Fungicides in Corn

Mark Jeschke, Ph.D., DuPont Pioneer Agronomy Information Manager Summary  DuPont Pioneer has conducted extensive research to better understand the value of foliar fungicides treatments in corn production.  Corn yield increased an average of 8.3 bu/acre in response to a foliar fungicide application across 1476 on-farm trials conducted from 2007 to 2016.  The average yield response to foliar fungicide application among on-farm trials was greater with practices that leave large amounts of residue on the soil surface, such as cornfollowing-corn, and no-till or strip-till.  Fungicide yield response varied greatly among ten smallplot research locations in 2009, from 0.6 bu/acre to 22.6 bu/acre, due to differences in disease pressure.

A positive return from a fungicide application is more likely when conditions favor foliar disease development.

 Results of a three-year University of Tennessee/ Pioneer study showed that the probability of using a fungicide profitably is directly related to the susceptibility of a hybrid to the predominant leaf diseases in the field.

2007 and 2016. These studies involved several different foliar fungicide products and included both aerial and ground applications, but all were focused on application timings between tasseling and brown silk (VT-R2).

 Among Pioneer on-farm trials, grain moisture of fungicidetreated corn was only slightly higher (+0.39 points) than non-treated corn.

 On-farm fungicide trial survey: Survey of on-farm foliar fungicide side-by-side trials conducted between 2007 and 2016.

 Later-maturing fields can be at greater risk for yield loss due to foliar diseases and therefore are more likely to benefit from a fungicide application.

 Pioneer small-plot research: 2009 study conducted to identify factors influencing yield response of multiple hybrids to foliar fungicide application across several Midwestern sites.

Introduction Over the span of only a few years, foliar fungicide treatments have progressed from a mostly new and untested practice to a trusted component of many growers’ management systems. This has occurred as research results and grower experience have demonstrated that fungicides can be very effective tools for managing foliar diseases and protecting yield in corn. However, studies have also shown that fungicide applications do not always result in an economic benefit for growers. Extensive Pioneer research conducted over the last ten years has demonstrated that the value of fungicide applications depends on disease pressure, hybrid susceptibility, previous crop, and tillage.

 University of Tennessee/Pioneer small-plot research: 2006 to 2008 study comparing foliar fungicide response among hybrids with differing levels of genetic resistance to gray leaf spot at a site chosen specifically due to its history of high GLS pressure.

Yield Response to Fungicide Treatment Between 2007 and 2016, DuPont Pioneer researchers conducted a total of 1476 on-farm fungicide trials comparing yield and moisture of non-treated corn to corn treated with a foliar fungicide between tasseling and brown silk. Across these trials, the average yield response to fungicide application was an increase of 8.3 bu/acre (Figure 1).

Figure 1. Corn yield response to foliar fungicide application in 1476 DuPont Pioneer on-farm trials conducted from 2007 to 2016. A positive yield response to fungicide application occurred in 82 percent of the trials. Yield response varied widely among many of the trials, as was expected given differences in weather conditions, disease pressure, and trial locations. Pioneer small-plot research found similar results, with an average yield response to fungicide treatment of 8.9 bu/acre across ten research locations in 2009 (Table 1). Average yield response varied among locations, ranging from 0.6 to 22.6 bu/acre, largely due to differences in disease pressure.

Table 1. Average corn yield response to foliar fungicide treatment at Pioneer small-plot research locations. Location

Table 2. Yield response necessary to cover the cost of fungicide and application over a range of costs and corn prices.

At a break-even yield response of 4 bu/acre, 65% of the Pioneer on-farm trials conducted over ten years would have seen an economic benefit from fungicide application (Figure 1). However, at a break-even point of 8 bu/acre, the success rate drops to only 48%.

Factors Influencing Yield Response Disease Pressure

8.9

The economic viability of a fungicide application can vary greatly according to the price of corn and cost of the fungicide and application. Higher corn prices and lower treatment costs reduce the break-even yield response, while lower corn prices and higher costs increase it (Table 2).

Pioneer research has shown that one of the most important factors determining the value of a foliar fungicide application is disease pressure. Foliar diseases can occur anywhere corn is grown in North America but are more common in the warmer, more humid growing areas of the South and East. Most widely grown hybrids have at least moderate resistance to the major leaf diseases, which may be sufficient protection against low to moderate disease pressure. However, in years when weather conditions are very conducive for disease, a fungicide application can provide a substantial economic benefit.

There are two basic types of disease cycles among the fungal diseases that infect corn leaves. Most of the pathogens, such as northern leaf blight, overwinter in diseased corn leaves, husks, and other plant parts. Spores are produced on this crop residue when environmental conditions become favor-able in the spring and early summer. These spores are spread by rain splash and air currents to the leaves of new crop plants, where primary infections are produced. Secondary spread then occurs from plant to plant and even from field to field as spores are carried long distances by the wind. As the plants die, the fungi remain in the dead plant tissue.

prevalent was only 3.9 bu/acre. At sites with high common rust pressure, yield response to foliar fungicide application was greatest among hybrids with a low level of genetic resistance to the disease (Figure 2). Pioneer on-farm research trials conducted in Iowa from 2007 to 2014 demonstrated the extent to which corn yield response to foliar fungicides can vary year to year due to weather conditions. Disease pressure is generally lower under drought conditions, as development and spread of several common foliar diseases is favored by moisture and humidity. 2011 and 2012 were both abnormally dry years in Iowa, whereas 2007 to 2010, 2013, and 2014 all experienced normal to abovenormal precipitation in most parts of the state. The average yield response to foliar fungicides in on-farm trials conducted during the two drought years of 2011 and 2012 was well below the average response observed in years with greater precipitation (Figure 3).

The rust diseases have a different cycle because they do not overwinter in crop residue and cannot survive the winters throughout much of the Corn Belt. Instead, disease starts in corn fields in the Southern United States, and spores are windblown long distances into the Corn Belt. Disease onset depends on weather systems that carry the spores northward combined with favorable conditions for infection. Secondary spread occurs similarly to the other leaf diseases. Foliar infections can occur at any growth stage, and the earlier lesions develop, the more leaf area is reduced and the more damage results. However, plants are generally more susceptible to infection after silking. Damage may include yield losses due to decreased photosynthesis and harvest losses if secondary stalk rot infection and stalk lodging accompany loss of leaf area. Treated

Non-Treated Figure 3. Average corn yield response to foliar fungicides in Iowa on-farm trials in drought years (2011-2012) compared to years with normal or above-normal precipitation (20072010 and 2013-2014). Hybrid Disease Susceptibility In Pioneer and university studies with multiple hybrids of varying disease resistance, the probability of using a fungicide profitably has often been directly related to the susceptibility of a hybrid to the predominant leaf diseases. PioneerÂŽ brand hybrids are rated on a scale of 1 to 9 for their level of genetic resistance to major foliar diseases, with 1 to 3 indicating a susceptible hybrid, 4 to 5 moderately resistant, 6 to 7 resistant, and 8 to 9 highly resistant. In cases where a foliar disease is not severe, a foliar fungicide application may not provide an economic benefit with a resistant or highly resistant hybrid. Hybrids that are susceptible to a common foliar disease are more likely to benefit from a fungicide application and should be monitored for disease symptoms, particularly when weather conditions are favorable for disease development.

Figure 2. A hybrid susceptible to common rust (3 on a 1-9 scale) treated with a fungicide (left) compared to the same hybrid, non-treated, showing severe common rust symptoms (right). As expected, yield was greatly improved by the fungicide application due to high disease pressure at this DuPont Pioneer research study near Seymour, IL. Pioneer small-plot research trials conducted in 2009 demonstrated the degree to which yield response to foliar fungicides can vary due to differences in disease pressure. The wide variation in yield response to fungicide application among locations was largely attributable to differences in common rust pressure. Common rust was prevalent at several Iowa, Illinois, and Indiana locations in 2009. Average yield response across locations in these states was 11.4 bu/acre (Table 1). Conversely, average yield response at Minnesota and Wisconsin locations where common rust was less

A research project was conducted over three years at the University of Tennessee Research and Education Center at Milan. The primary goal of this study was to determine the yield benefit associated with foliar fungicide management of gray leaf spot in hybrids with differing levels of genetic resistance. The research site was specifically chosen due to a history of high gray leaf spot pressure. The plot area was in irrigated no-till corn production for four years prior to the start 3

of the study, with a high level of gray leaf spot each year. Three Pioneer brand corn hybrids with differing levels of resistance to gray leaf spot were included in the study (Table 3). Table 3.

Figure 5. Average fungicide yield response of hybrids with low resistance (3 on a 1-9 scale) and moderate resistance (46) to common rust in Pioneer small-plot trials.

Results of the study demonstrated the potential for gray leaf spot to cause substantial reductions in yield when disease pressure is very high. Hybrid resistance was effective in mitigating a large portion of yield loss due to gray leaf spot; however, even with the most resistant hybrid, the yield benefit of the foliar fungicide application was great enough to likely cover the cost of product and application (Figure 4). Under more moderate disease pressure, a fungicide application would likely not provide an economic benefit on a resistant hybrid.

Common rust was prevalent at a trial at Macomb, IL, along with low to moderate levels of gray leaf spot and northern leaf blight. Notable differences in disease symptoms and yield response to fungicide were observed at this location (Figure 6). These research results from 2009 demonstrate the value of foliar fungicides in protecting yield when disease outbreaks occur; however, genetic resistance of hybrids may also provide adequate protection and should be considered in fungicide treatment decisions.

Another example is the small-plot study described previously where common rust was prevalent at some of the locations. Yield response to foliar fungicide application in this study was greatly influenced by genetic resistance of hybrids

to this disease. Among locations with high common rust severity in Illinois and Indiana, yield response to fungicide application was much greater for susceptible hybrids compared to hybrids with a moderate level of resistance (Figure 5). At Minnesota and Wisconsin sites with low common rust severity, a fungicide application could still have been profitable on susceptible hybrids (depending on prices) but most likely would not have been profitable on moderately resistant hybrids. 4

Other Considerations

Research results have clearly shown that corn-following-corn fields are at a higher risk and more likely to benefit from a fungicide application than corn-following-soybean fields. Survival of diseases in corn residue can lead to earlier infection and higher disease incidence and severity in the subsequent corn crop. Many common diseases, including gray leaf spot, northern leaf blight, southern leaf blight, eyespot, and northern leaf spot, overwinter in corn residue, providing a source of inoculum to infect corn planted the following season.

Grain Moisture One concern with fungicide treatments in corn is the potential for increased grain moisture at harvest, resulting in higher drying costs. Observations have varied among university trials with some showing a small increase in moisture in treated versus non-treated corn and some showing no difference. Among Pioneer on-farm trials, grain moisture of fungicide-treated corn was only slightly higher (+0.39 points) than non-treated corn. This difference was not greatly affected by overall moisture level at harvest. One possible reason a fungicide application could increase grain moisture at harvest is that disease pressure in the nontreated corn was severe enough to cause premature death of the plant. In such a case, the increase in moisture would probably be accompanied by an increase in yield, which may more than offset any additional drying costs. Hybrid Maturity and Planting Date Hybrid maturity and planting date have also been found to influence susceptibility to yield loss from foliar diseases (data not shown). These factors are important relative to the timing of disease development. Later planted fields and/or later maturing hybrids can be more vulnerable to yield loss because they are still filling grain while disease development is peaking in late summer. Therefore, these later fields are often more likely to benefit from a fungicide application.

Figure 7. Average yield response to foliar fungicide application as influenced by tillage and previous crop in onfarm trials (374 trials, 2007 to 2014). n = number of locations,

* = insufficient data.

Research studies have confirmed that tillage can influence disease pressure and potential benefits of fungicide application in much the same way as cropping sequence. By leaving more crop residue on the soil surface, conservation tillage and no-till can greatly increase the disease inoculum load.

The foregoing is provided for informational use only. Please contact your Pioneer sales professional for information and suggestions specific to your operation. Product performance is variable and depends on many factors such as moisture and heat stress, soil type, management practices and environmental stress as well as disease and pest pressures. Individual results may vary.

Survey results from 374 on-farm trials where previous crop and tillage practices were reported showed an inverse relationship between tillage intensity and yield response to foliar fungicide application in both corn following corn and corn following soybean (Figure 7). Rotation away from corn to a different crop, such as soybean, is often recommended as a way to manage corn diseases by reducing inoculum levels. These results support that recommendation and indicate that rotation with soybean does have a positive impact on reducing disease pressure; however, residue levels still appear to have an impact on disease pressure in corn following soybean. The 2009 DuPont Pioneer small-plot trials also included different cropping sequences and tillage practices among locations (Table 1). Average yield response to fungicide application tended to be higher among locations planted to corn the previous year and locations using no-till or strip-till practices; however, high yield response at some locations was driven primarily by common rust pressure. Common rust does not overwinter in crop residue, so would not be affected by crop rotation or tillage practices.

Soybean Aphid Soybean Aphid Pest Facts and Impact on Crop

Pest Symptoms/Injury ID

• Latin name is Aphis glycines Matsumura

• Shortened plant height • Curled leaves, often yellow on outside (similar to potassium deficiency) • Excessive honeydew on leaves, which promotes sooty mold growth • Presence of ants, which also feed on the honeydew

• Importance • Origin in Asia • First detected in US near Lake Michigan in 2000 • Major outbreaks in 2001, 2003, 2005 • Untreated economic infestations frequently reduce yields by more than 10 bu/acre • Development • Overwinter on buckthorn, move to soybeans in July and back to buckthorn in the fall • Host plants include a wide range of legumes (soybean, alfalfa, clovers)

Plants infested by soybean aphid are shorter (left)

Distribution

Aphid-infested soybean leaves

Natural Enemies • Asian lady beetle – adult or larvae • Chrysopa/Lacewing – adult or larvae • Syrphid fly – larvae • Predatory bugs – Minute pirate bug, Big-eyed bug, Damsel bug, etc. • Bio-control agent = Parasitic wasp – Binodoxys communis • Various fungal diseases

Soybean aphid distribution and area of increased probability of economic infestation

Causes of Yield Reduction • Removal of moisture, nutrients needed for grain production • Honeydew on leaves where sooty mold grows, which reduces photosynthesis • Transmission of viruses DuPont Pioneer Agronomy Sciences

Soybean leaves blackened due to sooty mold

Soybean Cyst Nematode SCN Best Management Practices • Plant SCN-resistant soybean varieties • Rotate host and non-host plants • Keep plants healthy • Maintain soil fertility • Prevent/reduce pest pressure (weed, insect, disease) • Sanitation

Non-host crop plants*         

Alfalfa Barley Canola Clover (red, white, ladino) Corn Oats Rye Sorghum Wheat

Host crop plants*  Soybeans  Beans (green, snap, mung, bush)  Adzuki beans  Birdsfoot trefoil  Cowpeas  Clover (alsike, crimson, scarlet)  Garden peas  Lespedeza  Sweetclover  White lupines  Vetch (common, hairy)

*Some plants may be considered “poor” hosts and thus be found listed as host or non-host according to various sources.

DuPont Pioneer Agronomy Sciences

SCN distribution in the U.S.

Example of Midwest rotation Year 1 SCN-resistant soybean variety* Year 4 Non-host crop Ex: Corn

Year 2 Non-host crop Ex: Corn Year 3 SCN-resistant soybean variety*

* Source of Year 1 and Year 3 SCN resistance should be from different source lines. If this is not possible, the minimum strategy is different soybean varieties.

Brown Stem Rot of Soybeans Disease Facts

Susceptible variety on left, resistant variety on right

• Caused by Phialophora gregata, a fungus that survives in soybean residue • Widely established throughout the north-central U.S., where soybeans are its only host • There are two known strains – strain A is highly aggressive, and strain B is mild • Fungus infects roots early in the season, but symptoms of vascular system damage usually appear in mid-summer, during reproductive development • Fungus is not carried with seed, and minimal amounts of inoculum are carried with soil adhering to farm equipment

Phialophora gregata Disease Cycle • Survives in infected soybean residue left on soil surface • Pathogen does not produce survival structures – survival is totally dependent on soybean residue • Fungus can continue to reproduce throughout the winter, influencing inoculum levels in the spring • Conidia (spores) are produced in the spring

Mature soybean stem infected by brown stem rot

Conditions Favoring Disease Development • Brown stem rot (BSR) development is greatest between 60 and 80ºF • Higher temperatures inhibit BSR – little or no disease develops above 90ºF • Severity and incidence of BSR is greatest when soil moisture is near field capacity, which is also optimal for crop development • Symptoms worsen if disease development is followed by drought stress during pod fill • Severity increases when soil pH is near 6.0 and is less severe at pH of 7.0 or greater • BSR may be more severe in fields where SCN is also a problem DuPont Pioneer Agronomy Sciences

• Infection of new soybean crop occurs through roots (by growth stage V3) and progresses to stems • Infected stems become inoculum source for next disease cycle

Impact on Crop • BSR infection progresses from roots to vascular system (water and food-conducting system) of soybean plants • Infection causes a gradual disruption of the vascular system • Premature plant death may occur, especially if heat and drought stress impacts badly diseased plants • Degree of yield loss depends on environmental conditions, variety, and fungal strain • BSR strain A causes more damage and may reduce yields up to 40% when severe ®, TM, SM

Sudden Death Syndrome of Soybeans Disease Facts • Fungal disease caused by Fusarium virguliforme • Has spread to most soybean-growing states and Ontario, Canada • Continues to spread to new fields and larger areas of infected fields • Ranked second only to soybean cyst nematode (SCN) in damage to soybean crop • Fungus colonizes only crown and roots of the plant • Above-ground symptoms are caused by a toxin produced by the fungus and translocated throughout the plant • Severity varies from area to area and field to field

Fusarium virguliforme Disease Cycle • Fungus survives in crop debris and as mycelia in the soil • Survives best in wet areas such as poorly drained or compacted field areas • Fungus enters roots early in the growing season • Infection may be facilitated by wounds from SCN, insects or mechanical injury • Fungus colonizes the root system • Fungus overwinters in diseased soybean residue

Impact on Crop Soybean seed yield is reduced as: • Plants lose leaf area and leaves drop prematurely • Roots deteriorate, reducing water/nutrient uptake • Flowers and pods abort, resulting in fewer pods and seeds • Seeds may be smaller, and late-forming pods may not fill or mature

Root Symptoms

Sudden death syndrome (SDS) of soybeans

• A blue coloration may be found on the outer surface of taproots due to the large number of spores produced

Conditions Favoring Disease Development • Cool, moist conditions early in the growing season often result in higher disease incidence

• These fungal colonies may not appear if the soil is too dry or too wet

• Favorable disease conditions may result from early planting, high rainfall and/or low-lying, poorly drained or compacted field areas • If SCN is also a problem in the field, disease may be more severe • Infection occurs early in the season, but symptoms usually do not appear until mid-summer

Blue mold

• Appearance of symptoms often associated with weather patterns of cooler temperatures and high rainfall during flowering or pod-fill DuPont Pioneer Agronomy Sciences

Wisconsin Soil Fertility Update

2016

Background

Objectives

• Balanced soil fertility management is critical for achieving crop genetic yield potential and maximizing profitability. • Recent evidence suggests that P and K fertilizer rates may not be keeping pace with higher nutrient removal rates that are accompanied by increasing crop yields. • The EncircaSM Yield Fertility Management Service is a new tool that can be used to balance fertility needs with crop budgets.

• Assess soil fertility levels in Pioneer Growing Point Agronomy on-farm corn research trials and fields enrolled in Encirca Yield services in Wisconsin. • Compare soil fertility levels measured in on-farm trials to state recommendations for corn. • Demonstrate how the Encirca Yield Fertility Management Service can be used to improve return on fertilizer investment for a typical field in Wisconsin.

Results

The foregoing is provided for informational use only. Please contact your Pioneer sales professional for information and suggestions specific to your operation. Results are based on the average of data at 889 locations through June 30, 2016. Multi-year and multi-location data are a better predictor of future performance. Do not use these or any other data from a limited number of trials as a significant factor in product selection. Product responses are variable and subject to a variety of environmental, disease, and pest pressures. Individual results may vary.

Soil Test Levels

• Phosphorus is critical in the process of converting solar radiation into energy and storing it as carbohydrates. • Optimum P fertility promotes early root and shoot growth as well as tolerance to drought, disease and temperature stress. • Potassium is vital in water regulation and enzyme activation. Stomata, which are openings in the leaf used for gas exchange, open and close by movement of K+ in and out of cells surrounding the opening. • Optimum K fertility promotes stalk strength and late season standability because it slows down stalk dry down after maturity. This helps stalks sustain greater elasticity and strength until harvest.

Soil test levels describe the probability that fertilizer application will result in increased yields. There is a good chance that it will be profitable to fertilize very low and low testing soils.

Yield Drives Fertility Maintenance Needs Corn Yield (bu/ac) 100 150 200 250

Importance of P and K Fertility

Maintenance of soil fertility levels requires application of at least as much fertilizer as was removed with crop harvest. Corn removes 0.38 lb. P2O5 and 0.29 lb. K20 per bushel, while soybean removes 0.8 lb. P2O5 and 1.4 lb. K2O per bushel. Over two years, 200 bushel corn followed by 60 bushel soybeans would remove about 120 lb. P205 and 115 lb. K2O per acre.
