As the corn crop nears maturity, knowing when you can safely terminate irrigation timing, while optimizing yield potential is likely the most important decision you will face. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Southwestern corn borer trap counts remained very high in some areas this week. The highest counts reported were in Sunflower, Quitman, and Coahoma counties.
The North Mississippi Research and Extension Center Field Day is scheduled for August 11, 2016 from 8 am to 1:30 pm with lunch provided.
Southwestern corn borer trap catches appear to be peaking this week. Several counties had individual traps with numbers at or near the current threshold and a couple well above threshold. As a reminder, the current threshold is 50 per trap
Southwestern corn borer numbers increased significantly in some areas this week. The highest numbers were 377 caught in Leflore County and 450 caught in Coahoma County. The current threshold in the 2016 Insect Control Guide suggests spraying when 50 moths are caught
Much of the corn has reached the reproductive stages, while some is still in the vegetative stages. Several caterpillars, including fall armyworm and corn earworm, can infest corn, especially non-Bt corn, during both stages of development.
To date, disease issues in the MS corn crop have remained somewhat quiet. Common rust has been the most prevalent disease as a result of wetter and cooler temperatures until the past 7 to 10 days. As of this morning (6/18/2016), southern rust has not been detected in MS.
Overall, southwestern corn borer traps remained low throughout the state. However, one trap in Leflore county captured 178 moths over a 7 day period. Although they do not appear to be widespread, this indicates that there may be pockets with
