DiPel® DF is an industry-leading, OMRI-listed biological insecticide formulated with Bacillus thuringiensis var. kurstaki (Btk) to control a wide range of leaf-eating caterpillars and worm pests. This dust-free, dry-flowable formulation dissolves easily in water and works quickly—larvae stop feeding within an hour of ingestion and typically die within several hours to three days. Available in 1-lb and 5-lb bags, DiPel DF is safe for beneficial insects, people, and animals, and is ideal for use on fruits, vegetables, ornamentals, turf, and other crops right up to the day of harvest.
