Welcome to the Plant Management Network's latest resource: Focus on Soybean, a web-based portal that includes educational webcasts, searchable resources, and websites that help plant practitioners enhance the health, management, and production of soybean crops. en-us http://www.plantmanagementnetwork.org/infocenter/topic/focusonsoybean/ The Plant Management Network Matt Helmers, Ph.D. This presentation will help consultants, growers, and other practitioners in the Midwest region increase their understanding of subsurface drainage and factors to consider when planning or evaluating the need for a subsurface drainage system. Specifically, the impacts of drainage on water movement, crop production, and nitrate-nitrogen loss will be described. In addition, factors to consider related to drain spacing and sizing will be described.

The use of raised bedding systems helps to increase and improve the consistency of soybean yields, especially in wet years. Because the topography of the Delta region is predominately flat, drainage is critical. Bedding systems help to provide improved surface drainage and facilitate furrow irrigation. Together, these practices are helping mid-South soybean growers produce more profitable and sustainable soybean crops.

It begins with some basic information about soybean aphid biology, reviews why scouting and thresholds are important, and then gives guidelines on when and how to scout for aphids. A few additional tools to complement your soybean aphid scouting program are also highlighted. Wed, 14 July 2010 12:45:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/SoybeanAphidScouting/ http://www.plantmanagementnetwork.org/edcenter/seminars/SoybeanAphidScouting/ Trey Koger, Ph.D. This presentation will help consultants, growers, and other practitioners in the mid-south and mid-west U.S. to better understand how to determine various vegetative and reproductive growth stages of indeterminate and determinate soybean. Information within this presentation illustrates why it is important to be able to determine soybean growth stages from one field to the next, as many in-season decisions with respect to pest management inputs are based on the presence, pressure, and/or thresholds of a specific or combination of pests at specific soybean growth stages throughout the growing season. Having a good understanding of soybean growth stages will aid in the process of making decisions on key production inputs such as pest management, irrigation timing and termination, and to estimate expected soybean maturity and anticipated timing of harvest.

Specifically, this talk will focus on the biology of the pathogen (Sclerotinia sclerotiorum), symptoms and signs, and risk factors associated with occurrence and disease development. Finally, management of Sclerotinia stem rot will be discussed with particular emphasis on resistance, and chemical and biological control. Thu, 29 Apr 2010 10:45:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/SclerotiniaStemRotofSoybean/ http://www.plantmanagementnetwork.org/edcenter/seminars/SclerotiniaStemRotofSoybean/ Erin Hodgson, Ph.D. This presentation will help consultants, growers, and other practitioners in the North Central region. The first presentation, titled Bean Leaf Beetle Biology, will be a brief review of the biology and life cycle of bean leaf beetle. It will also cover the damage potential of bean leaf beetle and bean pod mottle virus. The second presentation, titled Bean Leaf Beetle Management in Soybean, will focus on the proper sampling of bean leaf beetle, common IPM tactics and the proper use of economic thresholds to minimize yield loss in soybean. By the end of these presentations, the practitioner should be able to correctly identify and estimate field densities of bean leaf beetle. In addition, the viewer will understand the potential economic importance of this insect and make profitable management decisions.

Wright, Ph.D. This presentation will help consultants, growers and others in the agricultural industry of the South consider management techniques that need to be considered when double cropping soybeans. Management from planting to harvest will be discussed. Major topics covered are fertility, rotations, cover crop management, variety selection, row spacing and seeding rate, water needs, planting method and date, pest control and harvest considerations. This presentation will help growers consider every aspect of production and bring to mind some challenges that may be faced by growers during the growing season in the South. Mon, 22 Mar 2010 11:45:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/DoubleCroppedSoybeansintheSouth/ http://www.plantmanagementnetwork.org/edcenter/seminars/DoubleCroppedSoybeansintheSouth/ Chris Boerboom, Ph.D. This presentation will help consultants, growers, and other practitioners in the Midwest region in particular and interested agriculturalists across the country increase their knowledge about glyphosate-resistant weeds. The first presentation serves as a introduction to the issue of glyphosate-resistant weeds and highlights several important facts about the current status of resistance and challenges that will be faced by growers with resistance. The second presentation provides management considerations to either prevent glyphosate resistance or to control glyphosate-resistant weeds if they have developed in a field. Glyphosate and glyphosate-resistant crops are valuable tools for soybean growers and proactive stewardship should help sustain the utility of this technology into the future. Tue, 02 Mar 2010 8:30:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/Glyphosate/ http://www.plantmanagementnetwork.org/edcenter/seminars/Glyphosate/ Palle Pedersen, Ph.D. This presentation will help consultants, growers, and other practitioners in the U.S. on the basic mechanisms to maximize soybean yield. Examples will be given from Iowa that can be used for most states in the upper Midwest. In the presentation, basic soybean growth and development will be presented, and then this topic will be linked to management decisions. By the end of this presentation, the practitioner should know more about what it takes to maximize soybean yield, that it is all about agronomics and variety selection, and that yield is made much earlier in the growing season that most people think.

This presentation will help consultants, growers, and other practitioners in the Southern U.S. scout and manage the major nematode species on soybeans and other row crops. Nematode problems are widespread in the Southern United States and annually cause 5-10% yield losses for the total crop. In these four presentations we will cover: the biology and life cycle of SCN; symptoms caused by nematodes, how to use sample a field and how to interpret your results using damage thresholds; using resistant cultivars and crop rotations; and using combinations of nematicides and resistant cultivars. By the end of this presentation, the practitioner should know more about the life lifecycle of Southern root-knot, reniform, soybean cyst and Columbia lance nematodes and be able to design an appropriate scouting and management program.

Holshouser, Ph.D. Variety selection is one of the most important decisions a soybean producer makes and should be based on results of properly conducted variety trials. Types of variety trials in order of poor to good precision include split-field comparisons, un-replicated strip plots conducted over time and/or space, replicated head-to-head comparisons, and multi-location university-conducted official variety tests (OVT). All are useful and each has its own advantages in selecting high-yielding varieties. Never to use single-location, single-year data in a variety selection process; instead, use multi-location multi-year averages. Making selections based on that criteria will normally result in choosing high-yielding varieties the following year, regardless of where the variety is grown.

The Nutrient Uptake and Utilization presentation covers three areas of focus related to nutrient management. The first area of focus discusses the nutrients important for soybean production. The second answers the question, how does pH influence nutrient management decisions? And the third area of focus deals with the differences between macronutrients and micronutrients. The Fertilizer Application for Soybean presentation covers the principles of the various fertilizer application methods (broadcast, banded, and foliar) and helps the viewer decide which method is the best for the particular field and soybean crop at hand. Wed, 3 Jun 2009 12:00:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/SoybeanFertility/ http://www.plantmanagementnetwork.org/edcenter/seminars/SoybeanFertility/ Ray Schneider, Ph.D. Foliar diseases of soybean can be devastating in the South, especially in the Gulf South, where humidity remains high during the day and occasional tropical storms provide ideal conditions for disease development and spread. Diseases that rarely occur elsewhere in the U.S. may limit soybean productivity in this region. Furthermore, we cannot make broad generalizations about which diseases may be more or less severe in the South. A case in point is Cercospora leaf blight, which was a curiosity no more than 10 years ago but is now one of the most devastating and recalcitrant diseases in Louisiana. Asian soybean rust (ASR) is another notorious example. This disease, first discovered in Louisiana in November 2004, has the potential to cause substantial economic losses to the nationwide soybean industry, but Gulf Coast states are afflicted with this malady on a yearly basis. While producers in this region have learned to manage ASR and now view it as just another late season disease, there is a substantial cost associated with preventative fungicide applications, and this cost must be considered when calculating economic losses attributable to ASR. As described in this presentation, there is still much to be learned about these and other foliar diseases with regard to disease management. The purpose of this presentation is to provide a broad overview of the most prevalent foliar diseases in the South, including symptoms and diagnosis. The viewer is encouraged to seek advice from local consultants and extension professionals for literature, diagnoses, and specific disease management recommendations.

Infection occurs early in the season but symptoms typically don't develop until pod-fill stages later in the season. Brown discoloration of the stem pith and chlorosis and necrosis between leaf veins are symptoms of BSR, although the leaf symptoms do not always develop. BSR is managed with crop rotation and by using soybean varieties with resistance to BSR.

Dorrance, Ph.D. Phytophthora sojae is re-emerging as a key soybean pathogen in much of the US. This presentation will discuss why this is happening, explain how the different types of resistance work, and other disease management strategies that can be implemented to reduce yield losses. Producers and consultants can use this information first to learn the symptoms of this disease and then how to choose the right resistance package for those fields with Phytophthora sojae pressure.

Munkvold, Ph.D. Like most crops, soybeans are vulnerable to diseases caused by seedborne pathogens. These diseases can cause significant yield loss, reduce seed quality, and/or create obstacles to seed export because of phytosanitary concerns. Many microorganisms can be seedborne, but relatively few of them have a consistent economic impact. In this presentation, we will discuss how microorganisms can have different types of associations with seeds and which ones are important in soybeans. The presentation also briefly covers the methods used to detect some of the seedborne pathogens in soybean and a few management tips.

Esker, Ph.D. The use of foliar fungicides in field crop production, including soybean, has recently been on the increase. The increased interest in foliar fungicides is in part due to the discovery of Asian soybean rust in the U.S. in 2004. As a relatively new tool for soybean growers in the northern soybean production areas, the focus of this presentation will be increasing understanding of what is a fungicide, the role of integrated pest management in the fungicide decision process, the different types of modes of action that are currently available, the role of resistance management, application methods for foliar fungicides, and a discussion of some of the current results from different trials in the North Central region. To date, results from foliar fungicide trials have been variable and research is currently being conducted to determine under which situations the application of a foliar fungicide will be most effective.

Derksen, Ph.D. Asian Soybean Rust is a potential threat to soybean production in the United States. As demonstrated in other countries, inadequate protection against this foliar disease can significantly reduce yields. Asian Soybean Rust isn't the threat to young plants in the U.S. as it is in some countries but it could potentially infect taller, more mature canopies that are signficant challenges to treat with fungicides. To help establish guidelines on how to treat the lower portion of mature soybean canopies, field studies were established to characterize spray deposits and coverage produced by several different application techniques. These studies did not include efficacy evaluations but they have demonstrated which techniques could offer the best chance for protecting lower areas of mature soybean canopies.

Ragsdale, Ph.D. These presentations focus on two key areas of interest. The first presentation covers the biological aspects of the soybean aphid, including reproduction, feeding habits, and its effects on soybean yield. The second presentation, "Soybean Aphid: Economic Threshold and Economic Injury Level" discusses the points at which soybean aphid population densities go from benign to costly.

The first, Weed Competition in Soybean, focuses on the concept of weed emergence dates and the duration of weed interference in soybean and their effects on soybean yield. The Weed Management Strategies in Soybean presentation will focus on two common weed management strategies in soybean and the advantages and disadvantages of each strategy. It will also provide some insight on the value of soil-applied residual herbicides to for reducing variability of weed control and crop yields in soybean production.

In 2007, the national checkoff totaled more than $105 million. This presentation shows how soybean producers, through their soybean checkoff, are helping shape the future of the soybean industry. Soybean producers are helping revolutionize the industry by helping plant breeders develop soybeans that produce a more heart healthy oil for human consumption. These soybeans may one day be our World's commodity soybean improving human health world-wide. Scientists and plant breeders are diligently working to improve soybean agronomics. Soybean producers have also funded considerable work in genomics that has resulted in a robust physical map. In just the last decade soybean producers have helped discover Rps8, a new gene to protect soybean plants from Phytophthora, several new genes to manage the soybean cyst nematode, genes for resistance to Asian soybean rust, white mold, and brown stem rot. That's your soybean checkoff. Delivering results.

Fungicide seed treatments can improve seed germination and seedling emergence of poor-quality seeds due to fungal infection, in some cases. In addition, fungicide seed treatments can provide protection against seedling diseases caused by Fusarium, Phytophthora, Pythium, and Rhizoctonia. Benefits from fungicide seed treatments will not be observed in every field and every year, and benefits often depend on the environment. If cool and wet conditions occur after planting, benefits are more likely to be observed. When planting early or into fields with a history of seedling establishment problems, fungicide seed treatments may provide a benefit. Fungicide seed treatments can be considered as 'insurance' to help ensure uniform stands, and may pay off in the long run. Thu, 17 Apr 2008 00:00:00 CST http://www.plantmanagementnetwork.org/edcenter/seminars/fungicideseedtreatmentsforsoybean/ http://www.plantmanagementnetwork.org/edcenter/seminars/fungicideseedtreatmentsforsoybean/ Don Hershman, Ph.D. The Integrated Pest Management - Pest Information Platform for Extension and Education (ipmPIPE) was first conceptualized by USDA-APHIS during outbreaks of soybean aphid in the North Central U.S. during 2000-02. However, the ipmPIPE was not implemented until early 2005 when monitoring for soybean rust in North America became a priority. The ipmPIPE currently has three component parts: 1) Soybean aphid-PIPE, 2) Soybean rust-PIPE and 3) Legume-PIPE. The ipmPIPE now involves monitoring and reporting pests of soybean and various legume crops in 41 states, five Canadian provinces, and Mexico. Although information technology support for the ipmPIPE is state-of-the-art, the technology would fail without critical input from a host of support groups and individuals, especially Extension specialists and other scientists at Land Grant institutions, county Extension educators, crop consultants and producers. The ipmPIPE follows a traditional IPM template: 1) collect information, 2) analyze information, 3) make recommendations, 4) keep records, and 5) evaluation. Advances of the ipmPIPE over the existing IPM template include easy stakeholder access to national pest incidence and distribution data, disease forecasting, and state-specific control recommendations, through a public website, on a near-real time basis. The ipmPIPE has greatly enhanced communication among scientists and has facilitated the use of IPM in soybean. The ipmPIPE is very flexible and is amenable to other crop-pest combinations.

Most of them differ in maturity group, herbicide tolerance, yield potential, and then disease resistance. Some varieties are particularly well suited to meet specialty markets because of their chemical or physical composition. Specialty soybean tends to be consumed as food or processed to make foods. Specialty soybeans fall into many categories and are usually produced under a contract. Previously most specialty soybeans were the non-GMO type of soybeans or organic soybeans. Today, this has changed because of a strong demand for oils such as low linolenic. This presentation will cover the basics of specialty soybeans: the most common types planted, the and pros and cons of each, and the management of them.

The first part, titled Soybean Viruses: Biology and Symptoms will cover the most common soybean viruses with an emphasis placed on identification of each disease. An overview and introduction to viral diseases will be presented. Information on how each virus is transmitted will also be discussed. The second part, titled Soybean Viruses: Management Overview will focus on management options for soybean viral diseases. Management options will be discussed in general terms which focus on ways to avoid or reduce vector populations. Genetic resistance to viral disease will also be discussed. The source of virus will also be discussed in terms of how to reduce potential introductions.

In this series of modules, we discuss soybean variety selection, row spacing trends, changes in seeding rate and planting dates, and lastly re-plant decisions. These presentations are designed to provide recommendations that cover a wide range of environmental and geographic conditions.

Since that time, the disease has been found in a number of states where soybeans are produced, but has caused the most significant damage in states in the Southeast. In this presentation, Dr. Bob Kemerait addresses the reality of Asian soybean rust (biology, spread, detection, monitoring, management, and fungicde efficacy) as it relates to the experience of soybean producers in Georgia. The lessons learned through trial, error, and observation in a state like Georgia should serve as a good introduction for other states for the 'reality' of Asian soybean rust.

And although SCN is widely known as a serious yield-reducing pest, many fields infested with the nematode go undiagnosed. SCN can drastically reduce soybean yields if not detected when population densities are low. In this presentation, the biology and life cycle of SCN are described. The various symptoms caused by SCN are explained and illustrated, and specific scouting guidelines are presented. Finally, various SCN management options are discussed. This presentation can be viewed in three parts. Part one offers an introduction to the soybean cyst nematode and its biology. Part two covers SCN scouting. And part three discusses management of the soybean cyst nematode.

This presentation covers characteristics of Sclerotinia sclerotiorum, the cause of Sclerotinia stem rot, that are relevant to understanding the management of this disease. Sclerotinia stem rot is a disease of high yield potential soybeans. Most management practices intended to increase yield potential also increase the risk of yield loss associated with Sclerotinia stem rot. Management of Sclerotinia stem rot requires a coordination of soybean variety selection and adjustment to agronomic practices.
