Soybean Fungicide Small-Plot Efficacy Trials
Presented by Tom Allen

Associate Extension Research Professor, Plant Pathologist, Delta Research & Extension Center
Oftentimes university researchers use small plots (4 rows wide, 20-40 feet in length) to conduct fungicide efficacy research trials. In most cases the plot trials are organized to consider the efficacy of fungicide products on specific diseases. Over the past several years, small-plot trials have been used to assess the response of soybean to fungicides in environments when frogeye leaf spot was the predominant disease. However, over the past two seasons, target spot has been one of the main concerns of soybean farmers in the Mid-southern United States. Small-plot efficacy trial data on frogeye leaf spot, Septoria brown spot and target spot will be the main focus of this particular presentation.

Weed Control Programs In A PPO-Resistant Pigweed World Presented by Dr. Tom Barber Extension Weed Specialist, U of A Division of Agriculture
PPO-resistant Palmer amaranth (pigweed) has spread throughout many counties in Northeast Arkansas, West Tennessee and the Bootheel of Missouri. Sampling throughout Northeast Arkansas has indicated that there is approximately a 50% or better chance that PPO-resistance is present in producers' fields in that region. Knowing you have a problem with PPO-resistance is the first step in the management process. The second step is to develop a herbicide program that utilizes 2 effective modes of action PRE or at planting. Regardless of the technology planted, starting off on the right foot with multiple PRE herbicides will set the season up for success. In addition applying a second residual 21 days after the PRE application will continue to provide a level of protection. There are other cultural practices such as planting dates, narrower row spacing, cover crops and harvest weed seed control that will be discussed.

Management Of Redbanded Stink Bugs
Presented by Dr. Angus Catchot
Extension Entomologist, Mississippi State University
Redbanded stink bugs are an extremely damaging pest of soybeans that occur periodically across the Mid-South region. Mississippi first reported RBSB at treatable levels in 2009. Since that time numbers have been very low until 2016. Due to a milder than normal winter, numbers overwintered much further North than normal. As a result, soybean farmers across the Mid-South have experienced extremely high numbers in 2017. Many farmers have as many as 3 applications to control this pest. RBSB are much more damaging than our traditional species (Brown, Green, and Southern Green stink bug) and numbers build rapidly. This talk will address, control tactics, damage potential, and management strategies for RBSB in the Mid-South region.

Soybean Production In Southeast Arkansas: Our Methods For Maintaining High Yields
Presented by Rob Dedman
Arkansas Consultant: Soybeans, Rice, Corn, Wheat
Dedman will reveal some of the issues that he finds help produce high yielding soybeans, some of which are timely planting, timely application of fertilizer and pesticides and timely irrigation. He started consulting on his own in 2002 and now his business is known as Ultimate Ag Consulting, which helps farmers with rice, corn, wheat and soybean crops. His first experience with consulting was when he starting scouting rice while in high school under Dr. Nathan Slaton who was the Extension agent at the time. Dedman holds a bachelorÕs degree in agronomy from the University of Arkansas.

My Experience With Residual Programs In Soybean Production Regardless Of Technology
Presented by Chuck Farr
Arkansas Consultant: Soybeans, Cotton, Rice, Grain Sorghum, Corn, Peanuts, Wheat
Regardless of technology, residuals will be extremely important to use, Farr says. This is especially true in areas where there's PPO resistance. "That's where heavy overlaying of residual products is a must," he says. He will further discuss this issue during his presentation. Farr grew up on a farm in Crittenden County and has been consulting for 27 years. He holds a bachelorÕs degree in agronomy from the University of Arkansas and a masterÕs in plant science from Arkansas State University.

Small Acre Record Yields DonÕt Always Pay The Bills; Consistency Does
Presented by Perry Galloway
Arkansas Farmer: Soybeans, Corn, Wheat, Rice, Grain Sorghum
A common mistake farmers make is to boast of a small acreage that produced high yields while the rest of the field falls short, Galloway has a suggestion: Take a look at what contributed to the high yield and what prevented it. It could be disease, plant health, irrigation, or any number of reasons. He will discuss these in his presentation. Galloway raises 3,500 acres of soybeans, 2,000 acres of corn, 1,750 acres of wheat, 500 acres of rice and 1,000 acres of grain sorghum. He has been farming on his own since 1992, although he grew up on the farm.?He attended the University of Mississippi to study general business.

Nutrient Uptake And Demand In Mid-South U.S. Irrigated Soybean Production
Presented by Dr. Bobby R. Golden

Extension Agonomist, Mississippi State University ield experiments were conducted in 2016 and 2017 to determine total nutrient uptake, and nutritive demand of soybean cultivated in the mid-south U.S. research evaluated differing varieties and planting dates. Experiments were established in three fields at the Mississippi State Delta Research and Extension Center near Stoneville, MS that have a history of high soybean yields (>75 bu ac-1). This presentation will explore daily nutrient uptake rates and segmentation of macro nutrients in differing soybean plant tissues.

Soybean Yield And Automatic Fungicide Applications
Presented by Trent Irby
Arkansas Consultant: Soybeans, Cotton, Rice, Grain Sorghum, Corn, Peanuts, Wheat For a number of years, the automatic ÒR3Ó fungicide application has been a popular practice in soybean production. However, as fungicide resistance continues to progress, it is important to evaluate soybean yield response to automatic fungicide applications containing different commercially available premix and stand-alone products. Experiments were conducted during 2017 to determine the performance of automatic fungicide applications at different soybean growth stages (R3, R4, and R3 followed by R5.5).

Presented by Gus Lorenz
Distinguished Professor- Extension Entomologist, University of Arkansas Division of Agriculture
When commodity prices are down and the cost of production is up, it is imperative to keep profitability paramount when making decisions on insect pest management. Insect sampling, correct identification, using thresholds, and proper selection of insecticides is essential in sound and profitable management of insect pests in soybean.

Up And Coming Young Farmers Can Benefit From A Coach
Presented by Layne Miles

Arkansas Farmer: Soybeans, Corn, Cotton, Rice When a young farmer comes of age, he may think heÕs ready to take charge. But hold on! Miles has news for you. This is not a beginnerÕs ball game. ThereÕs marketing to learn about, how to manage pests, what to do when the weather turns your best plans upside down, in other words, expect the unexpected. Those lucky enough to have the advice of their father or another coach will benefit greatly from using that mentorÕs help. The Miles farm raises 1,500 acres of soybeans, corn and cotton in rotation, and 1,000 acres of rice. Miles received his bachelorÕs degree in plant and soil science from the University of Arkansas in Monticello in 2016. He grew up on the farm which his father still farms, now farming his 26th year.

Controlled Field Traffic To Avoid Compaction Throughout Field
Presented by Keith Morton

Mississippi Farmer: 1,000 acres Soybeans, Corn, Wheat Morton will discuss the benefits and challenges of controlled field traffic. Any field operation performed on his land with tractors, spreaders, fertilizer trucks all run in the same tracks as much as possible to keep from spreading compaction throughout the field. He uses auto steer and whatever he can implement thatÕs cost effective to make sure this system is followed. ÒIÕve been trying to implement this for about 10 years, but we had to do it in small increments,Ó he says. ÒWe waited until we needed to upgrade machinery then made sure the upgrade would correspond with the system.Ó Custom fertilizer and sprayer operators also started using auto steer to make sure their machine is following the same tracks. A fourth generation farmer, Morton grew up on the farm and raised his first crop on his own when he was 16 and in high school. He recently completed his 30th crop.

Increasing Soybean Yields With The Use Of Inoculants
Presented by Jeremy Ross
Extension Agronomist - Soybean, University of Arkansas System Division of Agriculture, Cooperative Extension Service
Historically, the use of soybean inoculants has been recommended for soybean production only in fields that have not had a history of soybean production, fields where soybean have not been grown in the last three to five years, or fields where previous soybean crops have had poor nodulation. Resent research evaluating soybean inoculants and planting dates have shown soybean yield increases with the use of inoculants in later plantings. Soybean planting dates ranged from mid-May to mid-July. No significant yield increases were seen from the mid-May planting dates, but the June and July plantings dates both showed significant soybean yield increases with the use of inoculants compared to the non-inoculated plots. Average soybean grain yields declined as the planting date were delayed; however, the differences in soybean grain yield between the non-inoculated and inoculated treatments as greater as planting was delayed. Several commercially available inoculant products were evaluated during this study, and no significant difference in grain yield was observed between products. In addition to small plot research, seven on-farm replicated test were conducted during 2017 to see if similar results were seen with large-scale production. Data from the small plot and large-scale studies will be presented during this presentation. Based on this research, production recommendations for soybean grown in Arkansas have been modified to recommend the use of inoculants on any soybean crop planted after May 15
