Arkansas County Corn Nematode Survey

Arkansas County boasts a rich farming history, with corn emerging as a major crop in our region over the past decade. Despite its relatively recent prominence, corn has swiftly become integral to our agricultural landscape, significantly boosting the state's output. As a vital component of our crop rotation system alongside rice and soybeans, corn offers a plethora of benefits, including enhanced weed control through additional herbicide action modes. However, the threat of pests, such as nematodes, looms large, posing a significant risk to yields and often resulting in misattributed reductions.

To tackle this challenge head-on, we launched a comprehensive corn nematode sampling program, generously supported by USDA-NIFA grant funds and the Arkansas Corn and Grain Sorghum Board. Our primary objective was clear: to assess the prevalence and severity of nematode infestations in Arkansas County's corn fields, empowering local producers with actionable insights for informed decision-making.

Commencing in spring 2020, we adopted a systematic sampling approach, meticulously selecting fields across the county during the V3-V4 growth stage of corn. Soil samples underwent thorough analysis at the Arkansas Nematode Diagnostic Laboratory in Hope, AR. Over four years, we gathered data to evaluate nematode levels in our corn production fields.

Additionally, we published yearly reports summarizing our findings and insights. These reports provide a comprehensive overview of the nematode situation in Arkansas County, serving as valuable resources for farmers, researchers, and stakeholders in the agricultural community.

At the recent county crop production meeting in February 2024, we proudly presented our findings. After comprehensive data analysis spanning four years, we are glad to report that Arkansas County currently faces no significant corn nematode problem. Consequently, there is no immediate need for seed treatments or additional nematode control measures. This not only conserves valuable resources but also optimizes agricultural practices, ensuring sustainable corn production in our region for years to come.
