Stay in the Know on Greenhouse Pest Management Options

Michigan State University (MSU) Extension has updated its insect and disease management recommendations for the 2021 greenhouse season. These recommendations are updated yearly to reflect efficacy of pesticides as MSU Extension specialists and their nationwide colleagues perform research trials evaluating the products against common greenhouse insects, mites, or diseases. The pesticides are evaluated by a network of researchers involved in the IR-4 Project, a research group that facilitates the labeling of pesticides on specialty crops, including greenhouse crops.

On the insect front, the recommendations address control strategies for thrips, aphids, whiteflies, spider mites, broad and cyclamen mites, and fungus gnats in both ornamental and vegetable production.

Disease recommendations focus particularly on downy mildew, a problem for many operations. There are also specific guidelines for vegetable and herb crops.
