Alert Details

An active weather pattern along with warmer than average temperatures on gusty south to southwest winds will increase prospects for at least isolated corn earworm migration events this week. Despite the fact that the vast majority of fields are not at a susceptible stage to damage as of yet in the corn-growing region, speciality/fresh market and local/home garden growers may face a risk from any migrating corn earworm population as those will be the only desirable hosts present. Low migration risks are predicted tomorrow night into Wednesday morning across Kansas, southern Nebraska, southern Iowa, Missouri, Illinois, Indiana, western Kentucky, and western Ohio. Low risks continue as a cold front moves southeast but then re-focuses further north as a warm front late this week but mainly across Kansas, Nebraska, southern Iowa, Illinois, and Missouri. Growers with vegetables or crops at susceptible stages to corn earworm should monitor traps and scout those crops for potential new moths in the coming week especially in or near the risk area. Problems are expected to be isolated, but could be locally intense given the general lack of suitable hosts further north outside of mid-south source regions at the present time.
