High pressure is expected to remain in control across much of the Corn Belt through Wednesday so no risk of corn earworm migration is predicted through noon Wednesday. Looking at the extended period, the next low pressure system is expected to move into the western Plains states. This system is expected to be a slow mover across the central part of the country, so the result will be the potential for a longer duration of southerly winds starting Thursday and continuing through the weekend. CEW trap captures from late last week across the mid-south show rather low numbers in comparison to the past few years at this time, and with ongoing flooding/delayed planting, concerns over the number of actively available moths in the source region are present. Additionally, southerly winds are not expected to be quite as strong as they were with last week’s system. Therefore, only Low corn earworm migration risks are predicted late week and into next weekend across the Plains and western/central Corn Belt.
