The Bacillus thuringiensis ssp. kurstaki (Btk) bacteria found in BT NOW contains natural insecticidal endotoxins called “cry toxins”. When consumed by the larval stage of target lepidoptera pests, these toxins bind to specific receptors in the insect’s gut which immediately disrupts and paralyzes certain digestive functions. After the pest consumes Btk, plant tissue will be protected from further damage as the pest halts all feeding within hours. As the activated toxins disrupt membrane integrity in the caterpillar’s midgut, Btk spores enter the body, proliferate and kill the pest 2-5 days later.
BT NOW and Trichogramma are two naturally occurring biological organisms that specifically target lepidopotera species and when used together create an effective caterpillar management program. This combination achieves excellent control of caterpillars without harmful residue and without disrupting
