Substance origin

Natural

Mode of action

Mode of action is purely physical, substance coats and dries on target pest blocking the spiracles and leading to death by suffocation. Also has entrapment properties.

Substance source

Plant sugar derived mainly from rice, corn, wheat and potato starch

Substance production

Manufacturred for commercial applications by the heating and gelatinizing a food-grade starch,followed by the partial hydrolysis with various acids and enzymes.

Uses

Crop protection

Target pests

Spider mite; Whitefly; Thrips; Leafhoppers; Scale; Mealybug; Aphids

Target host

Most edible and non-edible crops including soft, top, cane and bush fruit

Farming system suitability

Suitable for use in all farming systems where approved for use in that country
