Bacillus thuringiensis k (BT – Kurstaki)
The mode of action of Bacillus thuringiensis is that it can produce two types of toxins, endotoxins (companion crystals) and exotoxins, which stop pests from feeding. Pests die from hunger, blood damage, and neurotoxicity.
Target Pests: Lepidoptera pests on the crops and forests,such as diamond-back moth, cabbage butterfly, cotton bollworm, oriental tobacco budworm, rice skipper butterfly, corn borer, rice stem borer, American white moth, poplar notodontidae, pine caterpillars, and other important pests.
