Weed control is one of the primary inputs for soybean production in the midsouthern U.S. Many challenges face soybean growers in the area; however, new tools are available that will assist growers in mitigating the negative effects of weeds in soybean.

Advances In MidSouth Soybean Insect Pest Management
Presented by Dr. Sebe Brown

Extension Entomologist, LSU AgCenter
Midsouth soybeans are plagued by a complex of yield limiting arthropod pests that are becoming increasingly difficult to control. Adding to this issue is the lack of new insecticidal modes of action for control of important defoliators and seed feeders. This presentation will focus on potential insecticides on the horizon for control of soybean loopers and new use strategies of currently labelled insecticides for control of stink bugs, particularly the redbanded stink bug.

Fertility Requirements For Soybean Production
Presented by Dr. Bobby R. Golden

Extension Agronomist, Mississippi State University
Presentation will discuss nutrient removal in various soybean production systems and fertilizer requirement to sustain high yielding soybean production in the Mid South.

The Perfect Storm With Cover Crops
Presented by Robbie Howard
Louisiana Farmer: Soybeans, Corn
It was a "perfect storm" the past spring when Howard was waiting to get his crops in. With land next to the Mississippi River levee and the whole farm in cover crops during a wet spring with regular rain, it was quite a task to destroy the cover crop and find dry ground to plant. "In some instances I did let it go too far," he says. However, it appears he mastered the problem. In his presentation he will review the struggle and reveal what he has learned. Howard is farming land he purchased in 1972. His son, Keith, joined him about 1990 and together they raise 2,880 acres of soybeans and corn

Soybean Planting Considerations For Optimizing Yield Potential
Presented by Dr. Trent Irby

Extension Soybean Specialist, Mississippi State University
Many factors including, but not limited to, planting date, row spacing, and seeding rate/final plant population contribute to yield potential for soybean. Given that environmental conditions across the Mid-South during the planting season often are at one extreme or another, finding the balance between these factors can sometimes be difficult. Determining the ideal combination of row spacing, planting date, and seeding rate while also being prepared to implement best management practices when facing adverse conditions that result in sub-optimal plant populations may assist producers with optimizing soybean yield potential and ultimately profitability.

Managing Red Banded Stinkbug In Soybeans
Presented by Harold Lambert

Louisiana Consultant: Soybeans, Cotton, Corn, Grain Sorghum, Wheat, Sugar Cane, Rice
Red-Banded Stinkbugs moved into Louisiana about 10-12 years ago from South America, and Lambert will discuss some of the critical issues to take into account when trying to control them. He will go into the timeliness of spraying, the tank mixes to use and other details farmers need to recognize. Lambert has been consulting for 37 years, presently helping farmers fight problems on about 20,000 acres. He holds a bachelor's degree in agronomy and a master's in entomology, both from LSU.

Evaluating Winter Cover Crops Species And Seeding Rates For Louisiana Soils
Presented by Donna S. Morgan
Conservation Agronomist, Central Region Lousiaian Master Farmer Program, LSU Ag Center
Integrating cover crops into a modern-day agricultural operation can be challenging, even with potential benefits such as reduced soil erosion, increased crop yields, improved soil health, and weed suppression. With the renewed interest in cover crops over the last few years, LSU AgCenter agronomy research is now focusing many of their trials on evaluating factors that affect potential cover crop use. These factors may include planting methods, monoculture and polyculture species, seeding rates, planting dates, and even soil type. A two-year study was implemented in the fall of 2016 at the Dean Lee Research Station in Alexandria, LA to evaluate seeding rates for monoculture winter species (cereal rye, crimson clover, and tillage radish) and their impact on soil nutrient levels and cover crop biomass in a soybean production system. This study was conducted on a Coushatta silt loam and Moreland clay soil. Results indicate significant differences in several soil nutrient levels for soil type and season, as well as CEC levels and soybean yield. Additional research under various environmental conditions should continue before recommendations can be made for specific species and seeding rates with different soils.

Soybean Disease Identification And The Potential Impact Reduced Tillage Systems Have On Their Development
Presented by Dr. Boyd Padgett

Extension/Research Plant Pathologist, LSU Ag Center
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. Therefore, accurate identification is critical for effective management. Identification and development of the major diseases affecting soybean produced in the Mid-South will be discussed.

Practices To Control Worms In Soybeans
Presented by Ashley Peters

Louisiana Consultant: Soybean, Cotton, Rice, Corn, wheat, Grain Sorghum, Sweet Potato
With experience in using Heligen and Heligen PLUS products, Peters will relate his experience using both products for lepidopteran pest control in soybean in 2018. Both products are NPV's (nucleopolyhedrovirus), that you spray on the field, worms become infected, and it spreads throughout the field to control the yield-robbing pests. Both products offer economically feasible, resistance management options to growers when controlling corn earworm and soybean looper in soybean. Peters has a bachelor's degree in agronomy with a minor in ag business, and a master's degree in entomology, all from Louisiana State University. He is a self employed consultant since 2010.

Soybean Taproot Decline: Diagnosis, Yield Loss, And Management Options
Presented by Dr. Trey Price

Assistant Professor, LSU AgCenter
Soybean taproot decline has been a significant problem in the southern United States for 10-15 years. However, the causal organism was only recently confirmed as a Xylaria sp., and the origin of this unusual fungal pathogen remains a mystery. Taproot decline foliar symptoms are very similar to and may be confused with many other maladies of soybean, which makes diagnosis difficult in some cases. Fields in soybean monoculture and reduced tillage systems are at the highest risk for taproot decline. Results from ongoing research projects indicate that yield losses from taproot decline are significant, crop rotation or tillage operations may reduce disease incidence and severity, and resistant varieties may be available to producers.

What Have We Learned From The "Grow For The Green" Soybean Yield Contest: A Look Back At The Last 20 Years
Presented by Dr. Jeremy Ross

Extension Agronomist Š Soybean/Professor, University of Arkansas System Division of Agriculture
Since 1999, Arkansas has had a soybean yield challenge conducted under the direction of the Arkansas Soybean Association. In 2007, the soybean yield challenge was renamed the "Grow for the Green" soybean yield challenge and an additional yield competition was introduced called the "Race for 100" soybean yield contest. Both soybean yield competitions were financially supported by soybean check-off dollars from the Arkansas Soybean Promotion Board. The "Race for 100" contest was designed to award the first Arkansas soybean producer who could produce 100 bu/ac or more on a continuous five acre area in a production field. No soybean producer achieved the 100 bu/ac level until 2013, when three Arkansas soybean producers broke the 100 bu/ac mark. Again in 2014, three producers reached the 100 bu/ac level, with one producers setting a new state record soybean yield of 112.012 bu/ac. The current state of 118.8 bu/ac was achieved in 2016 by a producer in Craighead County. As of 2017, there have been 19 soybean producers who have broken the 100 bu/ac mark. During this presentation, production practices and trends of the producers participating in the "Grow for the Green" will be discussed.

Identifying And Characterizing Soybean Varietal And Nutritional Resistance To Cercospora Leaf Blight
Presented by Dr. Brian Ward

Post-Doctoral Researcher, LSU Ag Center
Cercospora leaf blight is a serious disease of soybean in the southeastern United States for which resistance has yet to be found. Widespread testing of commercial varieties and breeding lines has yielded a starting point for breeders to incorporate resistance and helped to categorize the sporadic varietal resistance over location. A resistance screening assay has been developed which can account for much of the variation observed across locations and will further aid breeders in rapid screening. Much of this resistance fluctuation is explained by nutritional availability and a cultivarÕs proficiency at nutrient utilization on a given soil type. Furthermore, collections of pathogen isolates from across the southeast has allowed us to better understand the population dynamics involved with the disease.
