Another Year to Remember for Insect Management?
The Insect Management and Insecticide Evaluation Program team has ambitious plans for applied field research this season. Some projects will assess the efficacy of various products on specific pests; others will investigate the effects of certain insects on crop growth and development; still more will study the effects of crop production practices on pests. Information from readers in the field is always desired.
