Dursban Insecticide by Crystal Crop Protection is a reliable solution featuring chlorpyriphos 20 EC, known for controlling major insect pests across various crops. This chlorpyrifos insecticide acts through contact, stomach, and fumigant action—offering triple protection against a wide spectrum of pests including aphids, borers, whiteflies, and termites.
Dursban inhibits the acetylcholinesterase enzyme in insects, disrupting their nervous system and causing paralysis. It is non-systemic and shows quick knockdown with residual effect, making it a go-to choice for both field and horticultural crops. Dursban 20 EC also plays a key role as a fruit borer insecticide in vegetables and orchards.
It is widely applied across paddy, cotton, sugarcane, vegetables, and fruit crops. It also protects structures during pre- and post-construction as an effective solution of dursban for termites. Farmers prefer it for consistent field results and flexible usage timing.
