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.
Controlling GR Palmer amaranth on turnrows and ditchbanks has become a critical component to weed control.
Corn reproductive stages generally comprise about 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions.
Incomplete kernel set is something you can’t ignore. These kernels usually don’t fill because the plant can’t supply enough energy to support them. Therefore, if we want to improve our yields, we need to investigate reasons why kernel set is less than desired, so we can do better in the future.
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 corn disease season continues to be somewhat quiet. Few if any foliar diseases have been observed throughout MS. Southern rust continues to be observed in western and southern MS; however, the disease has only be observed at low levels (one to two leaves) in all situations to date.
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
