20 greenhouse disease resources just a click away

University Resources

• Each year, Michigan State University Extension updates its insect and disease management recommendations for the next 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 pests 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.
• University of Massachusetts offers a list of best management practices for disease control, including a checklist of safety tips, cultural practices, airflow and humidity control, and soil treatment.
• Proper greenhouse sanitation is important for healthy, disease-free vegetable transplant production. Efforts need to be made to keep transplant production greenhouses free of unnecessary plant debris, soils, and weeds that may harbor pests and disease. Rutgers University has information on transplant production and treatment of flats and trays.
• The New England Vegetable Management Guide is intended to assist commercial producers by providing information on production techniques and pest management. The guide highlights management practices that will reduce disease in greenhouses and high tunnels, including the use of resistant varieties, sanitation, fungicides, and cultural practices that keep the humidity below 90%.
• Want information on diseases targeting specific crops? Cornell University has you covered at its Greenhouse Horticulture site, with a closer look at more than 20 crop categories, as well as advice for timely concerns such as impatiens downy mildew.
