What is BT NOW's mode of action?
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.
How should BT NOW be used?
Bacillus thuringiensis ssp. kurstaki products have a long history of safe and effective use in agriculture, forestry, and ornamental pest management. When applied properly, Btk products control lepidoptera larvae as well as traditional synthetic chemistries while also preserving beneficial species.
BT NOW is most effective on young, actively feeding larvae. For optimal results, employ early scouting programs to identify target caterpillar infestations and apply at first signs of feeding or when scouting program identifies pest presence. Cover foliage thoroughly to ensure product is consumed by the pest. Repeat applications when necessary to maintain control.
