Choosing for Organic Caterpillar Management

Start with scouting and pest identification, then select the labeled formulation for the caterpillar and growing site. For certified organic production, confirm the exact product and applicable restrictions with your certifier. BtK caterpillar products are not substitutes for Bti larvicides used for other target insects.
