Overview
Bacillus thuringiensis kurstaki (Bt-k, Lepidoptera Bacterial Insecticide) is a premium-quality product supplied by ZEAL BIOTECH under strict quality management with full batch traceability. Bt kurstaki Cry1A/Cry2 toxins specifically kill lepidopteran caterpillars (cabbage worm, cotton bollworm, corn earworm, fruit-tree moths) after ingestion; alkaline gut activates the toxin, which perforates midgut cells. Selective, non-toxic to beneficials/vertebrates, an organic staple.
