As growers across the country are either knee-deep in spring crops or preparing to plant, growers should remember to follow good sanitation practices to reduce disease, insect, and weed problems. Check out the e-GRO alerts “Sanitation: Start clean, stay clean!” and “Ounce of prevention” for good advice on preventing problems and pests.
Damping-off and root disease of annual bedding plants, broad mites in hanging baskets, and downy mildew on basil are already being seen in southern greenhouses. Luckily, there are more e-GRO alerts to help identify and manage greenhouse plant problems. Review “The problem with a picture: Pythium in propagation”, “Pythium Problems”, and “Rhizoctonia infection in high density fern production” for management recommendations of the most common damping-off pathogens, Pythium and Rhizoctonia.
Information on identifying plant symptoms and management of broad mites can be found in the alert, “Distorted and Stunted Growth: Ornamental Peppers”. Current information on managing downy mildew of basil is available in “Managing basil downy mildew in the greenhouse”. Having plant problems not mentioned here? Then, search the archived e-GRO resources for information on other pest, disease, and nutritional problems.
