Bacillus thuringiensis is a gram-positive bacterium found in soil, often used as a biopesticide . During sporulation it releases δ-endotoxin with insecticidal action. Caterpillars ingest the bacterium when feeding and die within days. It is best to apply in the earlier stages of caterpillar development !   Application:   Shake well before use! Dilute 2-3ml in 1l of water to make a foliar spray! Do not use together with bactericides! Spray liberally on and under the leaves! Repeat after 7-10 days in case of heavy infestation!
