Krishikranti Bacillus Thuringiensis (BT) Bio Larvicide for Caterpillar & Larva Control

Krishikranti Bacillus Thuringiensis (BT) Bio Larvicide is a biological insecticide (larvicide) used to control caterpillars and early-stage larvae in crops.

Larval pests like leaf-eating caterpillars, fruit borers, and loopers damage crops by feeding on leaves and fruits, which reduces plant growth and yield.

This product is suitable for farmers who want a biological solution for larva control, especially in vegetables and field crops.

Mode of Action

Krishikranti BT works through stomach action on larvae.

• The bacteria produce toxins inside the insect gut
• This stops feeding and damages the digestive system
• Larvae gradually stop feeding and die

It is most effective on young larvae (early stage).
