S5-2 Soybean Fungicides And Soybean Fungicide Efficacy On Important Foliar Diseases
Presented by Dr. Tom Allen Associate Extension Research Professor, Plant Pathologist, Delta Research & Extension Center
Since 2005, the number and types of fungicides available for soybean production systems have greatly increased. At present, many commercially available fungicide products contain multiple active ingredients, in most cases two and three-way mixtures. In addition, the increased availability of generic products means that farmers can tank mix individual fungicides. The presentation will address the specific products labeled for use in soybean production systems as well as addressing some new fungicide products.
S9-1 Developing Sustainable Managment Program For Foliar And Seedling Diseases Of Soybean
Presented by Dr. Jason P. Bond Professor of Plant Pathology, Southern Illinois University
Presented by Dr. Ahmad Fakhoury Associate Professor, Southern Illinois University
Each year, U.S. soybean growers lose as much yield to disease as the entire soybean production of China. Foliar diseases costs U.S. soybean producers approximately $700 million/year in yield losses, whereas seedling diseases costs 35M bushels loss annually. We will be presenting data from two ongoing United Soybean Board Š funded projects. The goal of these national projects is to develop cost-effective and sustainable managemenet options for major foliar and seedling diseases of soybean by gaining a better understanding of the biology of these diseases to optimize disease management strategies, identify disease-resistant varieties, and assist in the development of resistant germplasm.
S3-2 Profitability With Conventional Soybean Production Through The Use Of Cover Crops And No Till
Presented by Adam Chappell Arkansas Farmer: Soybean, Cotton, Corn, Rice, Chappell Brothers Farms, LLC
Because of rising input costs and falling commodity prices, farmers are under immense pressure to produce huge yields to have a chance to maintain profitability. This will be a look at that quest for profitability and how it can be achieved through the use of no till and cover crops. Because of advances in these areas, conventional soybeans have become a profitable option for our farm. We will discuss how we are able to control herbicide resistant weeds through cultural methods, as well as significantly reduce input costs in conventional soybeans due to improvements in soil health. These practices have provided an environment where a positive margin is possible without the stress of chasing record yields. Chappell raises 1,000 acres of cotton, 2,000 acres of corn, 4,000 acres of soybeans and 1,000 acres of rice on approximately 9,000 acres of farmland. He holds a bachelors degree in botany from Arkansas State and a masters degree in entomology from the University of Arkansas.

S1-2 Planting Strategies And Harvest Management Considerations
To Optimize Soybean Yield Potential Presented by Dr. Trent Irby Extension Soybean Specialist, Mississippi State University
Many factors contribute to yield potential for soybean. Given that environmental conditions across the Mid-South often are at one extreme or another, finding the balance between management strategies can sometimes be difficult. Determining when to implement best management practices when facing adverse conditions that result in sub-optimal plant populations may assist producers with optimizing early season soybean yield potential. Additionally, considerations for harvest management are equally important in order to protect already established yield potential and, ultimately, profitability.
S2-2 Soybean Management Considerations For The 2020 Cropping Season
Presented by Dr. Ben Lawrence Cropping Systems Agronomist (Extension Agronomist), Mississippi State University Delta Research and Extension Center
Soybean management during the 2018-2019 cropping season faced considerable challenges including from field preparation, herbicide options, application timings, and efficacy to harvesting logistics. In years such as these, careful considerations in crop management should be explored to maximize on farm profits.
S8-2 Where Is Weed Managment Headed In Future: Perceptions For An Academic
Presented by Dr. Jason Norsworthy Distinguished Professor, University of Arkansas
The utility of glufosinate, 2,4-D, and dicamba in commercially available soybean and cotton production systems will be examined along with opportunities and difficulties in prolonging the longevity of effective weed control programs in these current technologies. Recent research findings on sensitivity of Palmer amaranth populations to dicamba and glufosinate across the Midsouth will be examined. Emphasis will be placed on the continued need to overlay residual herbicides to maximize weed control and minimize chances of failures and selection for resistance.
S5-2 Soybean Disease Identification, Management And The Potential Impact Reduced Tillage Systems Have On Their Development
Presented by Dr. Boyd Padgett Extension/Research Plant Pathologist, LSU AgCenter The first step in disease management is accurate identification. Equally important, is an understanding of their development. Soybean is plagued by numerous diseases that can negatively impact yield and quality. The development of some of these diseases is impacted by reduced tillage systems. This presentation will address identification, development, and management of the major diseases affecting soybean produced in the Mid-South.
S7-1 Developing Pest-Resistant Soybean Varieties Adapted To The Mid-South
Presented by Dr. Trey Price Extension/Research Pathologist, LSU AgCenter
Soybeans have long been plagued by many maladies in the southern United States. Cercospora leaf blight (CLB) and red banded stinkbug (RBSB) are annual concerns for Mid-South producers that cause significant losses to yield and quality. During the 2016 growing season, a breeder-driven project funded by the United Soybean Board and Mid-South Soybean Board was initiated to identify publicly available germplasm with resistance to CLB and RBSB along with other important pests. A summary of results from the project will be presented.
S3-2 Conventional Soybean Production: Is This Production System Still Profitable
Presented by Dr. Jeremy Ross Extension Agronomist, Soybean-Professor, University of Arkansas Division of Agriculture Coop Extension Service
Prior to the introduction of Roundup Ready soybean in 1996, all soybean were grown by what is known today as the “conventional” production system. The Roundup Ready system revolutionized how soybean producers farmed soybean by allowing over-the-top applications of a broad spectrum herbicide to control problematic weed pest. With the widespread adaption due to weed control and ease of use of the Roundup Ready system, in a matter of three years over 65% of the US soybean acreage had changed from the conventional system. Today, a majority of the soybean varieties available to producers have inserted genes that provide resistance to several herbicides. Within the past five years, a renewed interest in “conventionally” produced soybean has developed due to consumer demand for non-genetically modified soybean for direct human consumption and animal products from animals feed conventional grown soybean. During this presentation, agronomic production practices and economics of the “conventional” soybean production systems will be discussed.
S6-2 Facing Grass Weed Management Issues In Tennessee
Presented by Dr. Larry Steckel Extension/Research Weed Scientist, University of Tennessee
Presented by Clay Perkins Graduate Student, University of Tennessee
Junglerice (Echinochloa colona (L.) and barnyardgrass (Echinochloa crus-galli) populations have consistently gotten worse over the past five years in Tennessee and the Mid-south. The thought of resistance to glyphosate and clethodim came to mind until resent research found that tank mixing with dicamba was leading to poor control. The antagonism from dicamba in the tank is being studied and further research is being conducted to better understand this interaction. When tank mixing dicamba in the tank with glyphosate or clethodim would lead to roughly 30% less control. When using TTI nozzles, a 5% reduction in control of Echinochloa was evident when to using XR nozzles. Moving forward, dicamba needs to be left out of the tank and sequential applications of glyphosate and clethodim need to be utilized when controlling this Echinochloa complex of weeds.
S4-2 Soybean Insect Control In A Challenging Year
Presented by Dr. Ben Thrash Extension/Entomology, University of Arkansas
This session will discuss strategies for managing insects in a year where late planted crops were combined with low commodity prices. Topics will include the benefits and drawback of several insecticides, the relative damage caused by various insects, management of low yielding soybean fields, and use of thresholds to make sound decisions.
S2-2 Determining Proper Row Orientation And Seeding Population For Soybean Production
Presented Dr. Richard E. Turner Research Associate II, PhD Student, Mississippi State University
Soybean planting seed cost is the greatest expense in most growing seasons. The objective of this study was to evaluate row orientations on 40-in rows (single-row [SR] vs twin-row [TR]) and planting populations (78,400, 104,500, 130,800 and 156,800) seed/acre. In 2017 and 2018 a field study in the Mississippi Delta was designed to determine whether canopy closure was impacted by treatment and the effect on yield and plant characteristics. Mapping data showed that soybean yield was maintained at low seeding rates. Data indicated that planting population could be reduced provided the existing stand was uniform in emergence.
S7-1 Evaluation Of Soybean Germplasm To Reduce Losses Associated With Poor Grain Quality
Presented Dr. Tessie Wilkerson Assistant Research Professor Delta Research & Extension Center, Mississippi State University
Poor grain quality resulting from delayed harvest can cause economic losses in the U.S. soybean production system. Research objectives will address the need for better soybean tolerance to mature seed damage by screening germplasm and developing and testing new breeding line sunder environmental conditions conducive to reducing grain quality. In addition, a more thorough understanding of associated pathogens and control methods will be explored. Results will have a direct impact on soybean breeders and farmers by helping them select the best genetics for resistance to mature seed damage and understand what management practices are effective.
