Garden Pest and Plant Disease Listing - BA

BACILLUS: A group of nontoxic bacterial (biological) insecticides. B. thuringiensis var. kurstaki controls caterpillars, such as cabbageworms. B. t. var. San Diego controls Colorado potato beetle; B. t. var. isralensis controls mosquito larvae. B. popilliae, also called milky spore, controls Japanese beetle larvae.

BASAL STEM ROT: Rot is likely to attack plants that have gotten too cold and/or damp, or that have a poor root system. Rot fungus quickly grows from the skin into the tissue, turning them soft and black. Cut off healthy pot plant stems for cuttings and destroy the rest. Apply copper sulfate to permanent plantings.
