C8-2 Options For 5-Way Resistant Palmer Pigweed Control In Cotton
Presented by Dr. Tom Barber Extension Weed Specialist, U of A Division of Agriculture
Palmer amaranth (pigweed) populations in Arkansas have been identified that are resistant to 5 known herbicide modes of action (MOA). These known MOAs include ALS (group 2), DNAs (yellow herbicides group 3), glyphosate (group 9), PPOs (fomesafen, group 14) and chloroacetamides (metolachlor group 15). This presentation will discuss options for control that are still available and management plans that have proven effective in Arkansas. Programs discussed will include cover crops and termination timing, technology selection, multiple effective residual herbicides applied at planting and effective residuals postemergence.
C5-2 Another Shift In Cotton Varieties
Presented by Dr. Fred Bourland Professor, University of Arkansas
Cotton varieties available for mid-south producers have experienced three major shifts in the last 25 years. Each shift has been associated with the introduction of new Bt technologies. Variety shifts associated with new weed technologies have been less conspicuous. These shifts have challenged producers and variety testing programs. Prior to the advent of transgenic cotton, variety testing programs relied heavily on 3-year means. Now, few varieties stay in variety tests over two years. Yield components can help to understand how varieties establish yield and may be incorporated into variety selection.
C1-2 Insect Management In Cotton: Experiences From A Crazy Insect Year
Presented by Dr. Angus Catchot Extension Entomologist, Mississippi State University
This talk will discuss the cotton insect situation growers faced in Mississippi in the 2019 growing season. Specifically addressing the erratic bollworm flight and reasons for lack of control with the diamide insecticides. Additionally, performance of VIP gene cottons and what to expect for the 2020 growing season will be discussed.
C4-2 A Different Way To Grow Cotton With Improved Soil Health
Presented by Adam Chappell Arkansas Farmer: Cotton, Corn, Soybeans and Rice
As production costs associated with traditional cotton production continues to increase coupled with current prices, it is obvious that an innovative way to produce cotton is critical in keeping cotton a profitable crop in the Mid-South. Improvements in soil health on my farm have opened the door to explore strategies used in other cotton production regions in an attempt to greatly reduce cost of production. The ins and outs of 76 inch cotton and impacts on my bottom line will be discussed.
C2-2 Four R Nitrogen Management For Cotton MU-FDRC Research Update
Presented by David Dunn Extension Associate, Soil Testing Lab & Rice Extension, Fisher Delta Research Center
Sustainable, Profitable cotton production requires fertilizer nutrient inputs including Nitrogen. Sound Nitrogen management is based on the 4 R's: The right source, the right rate, the right time and the right place. All of these rights are interconnected working in synchronicity with each other. None of the four will be right if any one of them is wrong. There are more than one possible right combinations however. This talk highlights the research conducted at the MU-Fisher Delta Research Center into nitrogen management for cotton.
C8-2 Weed Control Issues In Cotton Due To Resistance Problems
Presented by Chuck Farr Arkansas Consultant: Cotton, Soybeans, Rice, Grain Sorghum, Corn, Peanuts, Wheat
One of the most pressing issues Farr sees in working with cotton farmers is weed control, particularly Palmer pigweed resistance. He works in an area that is considered ground zero for resistance and knows it's only a matter of time before other technologies become resistant to Palmer.† He will discuss new technologies and how they will affect cotton farmers in the future. ďArkansas is one of†the most restrictive states in the nation in the use of dicamba,Ē he states, so he will attack the issue from a technology stand point and its best use for resistant palmer. Farr grew up on a farm in Crittenden County and has been consulting for 32 years. He holds a bachelorís degree in agronomy from the University of Arkansas and a masterís in plant science from Arkansas State University.
C10-2 Impact Of Rainfall On The Performance Of Insecticides In Cotton
Presented by Dr. Jeff Gore Associate Research and Extension Professor, Mississippi State University
Managing insect pests with foliar insecticides is an important component of cotton production in the Mid-South. Many factors can impact the performance of insecticides including product and rate choice, resistance, and weather events. The impact of rainfall on the performance of insecticides is not well understood, but is one of the most important questions that Extension entomologists have to address every year. This is especially true during the months of July and August when widespread isolated showers can be common.
C9-2 Target Spot - Results Of 6 Years Of TN Fungicide Trials
Presented by Dr. Heather Kelly Extension/Research Plant Pathologist and IPM Coordinator, University of Tennessee
Since the first report of target spot on cotton in Tennessee in September of 2013, research trials have been conducted across multiple varieties to evaluate fungicide application timing, number of fungicide applications, and fungicide products on disease efficacy and yield protection. This presentation will go over the 6 years of research trial data and the implications they have for managing target spot in the Midsouth.
C7-2 Cover Crops And Cotton: The Journey
Presented by Matt Fryer Instructor-Soil Science, University of Arkansas System Division of Agriculture Cooperative Extension Service
Presented by Wes Kirkpatrick Arkansas Farmer, Cotton
Challenges facing Arkansas cotton producers include poor irrigation efficiency, poor water infiltration, and any change in management needed to improve production. Despite the challenges faced by producer Wes Kirkpatrick, when implementing cover crops and soil health principals, many benefits have ensued. Soil health principals include no-till and keeping the soil covered with living roots growing for as many months out of the year as possible. The documentation of these practices through Arkansas Discovery Farms Program and other research have shown improved water infiltration, increased rooting depth of the cash crop, decreased water runoff, and improved profitability for the Kirkpatrick farm.
C5-2 Addressing Cotton Blue Disease In The US
Presented by Dr. Jenny Koebernick Assistant Professor, Cotton & Soybean Breeder, Auburn University
Cotton leaf roll dwarf virus (CLRDV), which cause the cotton blue disease, is capable of reducing yield by up to 80-90% in Argentina and Brazil. The recent discovery of CLRDV, in Alabama and other states, is causing great concern because this virus has the potential to severely damage the cotton industry. Collaborative efforts across disciplines and across states are ongoing in order to reduce the growerís risks. This presentation will discuss the symptomology of diseased cotton plants observed in 2018-19 and provide an overview of the current research efforts on breeding, entomology and virus projects that will lead to management solutions.
C3-2 Cotton Insect Management
Presented by Dr. Gus Lorenz Distinguished Professor - Extension Entomlogist, Assoc. Dept. Head, Entomology & Plant Pathology, University of Arkansas - Division of Agriculture
Each year, the bollworm (Helicoverpa zea, Bodie), infests 100% of cotton planted in Arkansas. It remains a major pest of post-bloom cotton in the Mid-South despite widespread use of transgenic varieties. Dual gene Bt cotton does not always provide adequate protection from lepidopteran pests to maintain potential yield. In years when bollworm populations are high, foliar insecticides are commonly used to supplement control of cotton bollworm. In recent years we have seen a decline in control of bollworm with dual gene cotton. A recent analysis of data indicates that there has been an increase in damage to squares which might indicate tolerance is developing to dual gene technologies. Economic loss to the grower based on cost of treatment and reduction in yield due to this pest totals more than $1.7 million or $9.41 per acre, in 2019 that figure is much higher. We will discuss the impact and efficacy of foliar oversprays on conventional and dual-gene cottons, and the role of 3 gene cotton for growers in the Midsouth.
C3-2 Delayed Potash Applications And Issues Affecting Cotton Production
Presented by Layne Miles Arkansas Farmer: Cotton, Rice, Corn, Soybeans
Miles has experimented with the delayed application of potash, and will relate how urea tests have aided cotton production. He also will discuss how his family has overcome adversity when his father’s best friend and farm manager for 23 years passed away, a situation many find themselves facing at times. The Miles farm recently grew to 10,000 acres when Layne and his dad, Matt, combined their acreage. On 1,500 acres they raise zero-grade rice, and of the balance of the acreage, 3,500 acres each is in corn and soybeans with 1,500 acres in cotton. Miles received his bachelor's degree in plant and soil science from the University of Arkansas in Monticello in 2016. He grew up on the family farm and he is now farming for his 28th year.
C1-2 A Consultants Perspective On Weed, Insect And Disease Control
Presented by Tucker Miller III Mississippi Consultant, Miller Entomological Services
Miller will focus on some of the new issues this year, one of which is the Cotton Dwarf Virus or leaf roll. He'll also touch on the insect side of the thresholds of the heilothis (boll worm) eggs. He will re-address the egg thresholds from the BG2 and BG3 varieties. Researchers suggest different thresholds, and sometimes it's OK and other times it needs to be refined," he says. He will touch on what consultants do in regard to weeds, insects and diseases. Today he consults on 30,000 acres of cotton, 5,000 acres each of soybeans and corn, as well as 1,000 acres each of peanuts and vegetables. He grew up on a farm where cotton, soybeans and rice were raised; on his own 2,000 acres, he raises soybeans, wheat and corn, but also raises cotton some years. Miller has a Bachelor's Degree in agronomy and a Master's Degree in plant pathology, weed science and entomology all from Mississippi State.
C10-2 Daily Challenges In The Life As A Cotton Consultant
Presented by Dr. John Hartley North Independent Ag Consultant, North Entomological Consulting
As technologies become more prominent and insecticides are more superior than previous chemistries, there seems to always be new challenging factors for a successful cotton crop. Many factors play a role when choosing insecticides for ideal control and residual for ideal insect control. Plant Management has become one of the most challenging tasks producers and consultants face. High yielding varieties have replaced less aggressive varieties from the past which can affect how consultants manage a cotton crop for insect, weed, and disease control.
C9-2 How I Use My Cost Of Production And Break-Even Point To Determine When To Market My Crop
Presented by Steve North Tennessee Farmer: Cotton, Corn, Soybeans, Wheat
North keeps close records on his cost of production, including all the variables besides the usual seed, chemicals and fertilizer. This helps him determine his break-even point which he uses to determine when to sell. "Most growers are unsure of their exact total production cost which can lead to poor marketing decisions," he says. All his crops were excellent this year, that is, those he was able to plant. Many acres couldn't be planted due to flooding. "Set a profit per acre goal before planting based on 5-year average yields and start sales when this goal is reached; and be realistic. I would rather reach in one pocket and pull money out than blow dust out of both pockets." He will tell growers what works for him in deciding when to start marketing his crops. North holds a Bachelor of Science degree in business administration from Union University in Jackson, Tenn. He grew up on a farm and he's been farming for 25 years, having also worked for Lauderdale Farmers Coop four years, Bayer Crop Science for 23 years, and Nutrien Ag Solutions for 14 years. He farms a total of 3,000 acres with normally 1,000 acres in cotton, 500 acres in corn, 1,500 acres in soybeans.
C11-2 Creating A Resilient Supply Chain With The U.S. Cotton Trust Protocol
Presented by Steven T. Pires Manager, Sustainability, Cotton Incorporated
Presented by Nathan Reed Arkansas Farmer: Cotton, Corn, Milo, Wheat, Soybeans
Increasing demand from consumers for more sustainable products is an ever-present reality for cotton producers, brands, and retailers. While most brands and retailers acknowledge that U.S. cotton is among the most responsibly produced and sustainable in the world, prior to the creation of the U.S. Cotton Trust Protocol, there was no U.S. centric system in place for cotton producers to provide assurances of this fact to the supply chain. This presentation will provide an overview of the U.S. Cotton Trust Protocol, how it relates to U.S. Cotton's 10-Year Sustainability Goals, and why this program is critical for both cotton producers and brands alike.
C2-2 The Fertilizer Application Process And My Success Planting Phytogen Cotton
Presented by Chris Porter Missouri Farmer: Cotton, Corn, Soybeans
Porter plants a different variety of cotton than many farmers. He plants the Phytogen cotton and used the Enlist spray program. He also will discuss his fertilizer application process and how he uses soil tests to determine the soil needs. He will open up the program for questions. He is a graduate of the University of Missouri, Columbia, with a bachelor's degree in ag business. He raises 1,500 acres of cotton, 500 acres of corn and 1,500 acres of soybeans on a 3,500-acre farm. Heís been farming since 1998 and this is his 21st crop.
C6-2 Fine-Tuning The Production System: Triggering Cotton Irrigation Events From Soil Moisture And Refining The DD60 Model
Presented by Dr. Tyson B. Raper Cotton Specialist, University of Tennessee
Monitoring soil moisture can save input costs even in exceptionally wet years. During the 2018 and 2019 seasons, deployments of sensors in Northwest Tennessee provided the insight into profile moisture and often prevented irrigation applications which would likely have been made if sensors had not been used. If coupled with more robust models of cotton maturity, information from soil moisture sensors could be used to time irrigation events which trigger only at the most critical times. Over the past two years, three cotton cultivars of varying maturity have been monitored weekly across the U.S. Cotton Belt to determine the date at which each reaches a given growth stage. This information will be used to reassess the DD60s required to reach each subsequent growth stage through maturity. Concepts covered will include cotton earliness, maturity, and determinacy.
C4-2 Basics Of Soil Health
Presented by Dr. Bill Robertson Professor, Cotton Extension Agronomist, University of Arkansas System, Division of Agri/Coop. Ext. Service
The lack of soil health is a major limiting factor in cotton production in the Mid-South. Practices including the adoption of a cover-crop and no-till method of production has a direct impact on soil health. Practices that lead to improved soil health often improves profitability and sustainability.
