BT NOW is a water-based, biological insecticide that utilizes a novel strain of bacteria, Bacillus thuringiensis kurstaki (Btk) strain EVB-113-19 (14.49%), to offer targeted control of the caterpillars of certain moths and butterflies on a wide variety of crops. Ingestion of BT NOW paralyzes the insect’s digestive system within hours, halting further crop damage potential. The affected larvae die within 2-5 days.
Benefits of BT Now:
- Easy to use liquid formulation
- Four-hour REI — Zero-day PHI
- Low residue — MRL exempt
- Can be used in conjunction with many beneficials and pollinators
- Ideal for IPM programs — Low resistance potential (IRAC GROUP: 11A)
- Tank-mix compatible with many commonly used pesticides, fertilizers and adjuvants
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.
Caterpillar Control in Fall Ornamentals
BT NOW effectively targets hatched caterpillars Trichogramma may have missed, giving growers the best chance of a successful harvest. This combination achieves excellent control of caterpillars without harmful residue and without disrupting beneficial insect populations.
