Seedcorn Maggot
According to degree day models, adult seedcorn maggot emergence from the soil peaked around March 21 in Georgetown, DE. On warm, sunny days adults can be seen resting on soil surface, particularly freshly disturbed soils. We recently recorded a YouTube video discussing seedcorn maggot which can be accessed here: https://www.youtube.com/watch?v=nDhj8QTz8hw.
Greenhouse Pests
Scout greenhouse transplants for aphids and spider mites. Destroy any weeds growing in the greenhouse to prevent mites from establishing on them and then moving onto transplants.
