Several important disease, insect, and weed problems can affect profitability of field corn production in New York. The most important pests are seed corn maggots, cutworms, armyworm, European corn borer, western and northern corn rootworms, ear molds, foliage and stalk diseases, and weeds. Some additional pests may occasionally cause economic losses. Integrated pest management (IPM) methods can be used to help minimize or avoid pest damage.
See the tables below for suggestions on IPM activities and common pests by crop growth stage and seasonal occurrence.
