Prevent Plant Problems Before They Get Started
As growers across the country are either knee-deep in spring crops or preparing to plant, growers should remember follow good sanitation practices to reduce disease, insect, and weed problems. Check out the e-GRO alerts “Sanitation: Start clean, stay clean!” (http://www.e-gro.org/pdf/2018_731.pdf) and “Ounce of prevention” (http://www.e-gro.org/pdf/2020_909.pdf) 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 has already being seen in southern greenhouses. Don’t get caught off-guard by these problems. Luckily, there are more e-GRO alerts to help identify and manage greenhouse plant problems. Review “The problem with a picture: Pythium in propagation” (http://www.e-gro.org/pdf/2019_804.pdf), “Pythium Problems” (http://www.e-gro.org/pdf/2017_608.pdf), and “Rhizoctonia infection in high density fern production” (http://www.e-gro.org/pdf/2018_714.pdf) 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” (http://www.e-gro.org/pdf/2016_538.pdf). Current information on managing downy mildew of basil is available in “Managing basil downy mildew in the greenhouse” (http://www.e-gro.org/pdf/E407.pdf). Having plant problems not mentioned here? Then, search the archived e-GRO resources at http://www.e-gro.org/ for information on other pest, disease, and nutritional problems.
