DiPel® DF Biological Insecticide Dry Flowable is a proven insecticide derived from a soil bacterium that selectively targets destructive caterpillars and worms on more than 200 crops. DiPel is an excellent choice for worm control because it delivers effective and economical control of worm pests. And, it has no harvest residue or MRL concerns because it is exempt from tolerances. DiPel is a great rotational or tank mix partner to reduce the potential of worms developing resistance to insecticides with other modes of action.
