About Profenofos 40% + Cypermethrin 4% E.C
Profenofos and cypermethrin are an insecticide blend, often formulated as a combination product like Profenofos 40% + Cypermethrin 4% E.C.. The blend combines two different chemical classes to control a wide range of pests, including both sucking and chewing insects, by affecting their nervous systems. Profenofos, an organophosphate, works by inhibiting an enzyme, while cypermethrin, a synthetic pyrethroid, acts on sodium channels for a rapid knockdown effect. How it works
- Profenofos: An organophosphate that inhibits the enzyme acetylcholinesterase, which is vital for nerve impulse transmission. This disruption leads to paralysis and death in insects.
- Cypermethrin: A synthetic pyrethroid that acts on sodium channels in the nervous system, causing hyperexcitation and convulsions, leading to paralysis and death.
- Synergistic action: The combination of these two chemicals provides a powerful, broad-spectrum control because of their different modes of action. This can also help manage insect resistance that may develop to one chemical alone.
Uses and applications
- Pest control: It is effective against a wide range of both sucking pests (like aphids, whiteflies, and mealybugs) and chewing pests (such as caterpillars and beetles). It is particularly useful for controlling pests like bollworms in crops like cotton.
- Crop protection: It is used on a variety of crops, including cotton, vegetables, fruits, and grains.
- Application: It is typically a foliar spray, meaning it is sprayed directly onto the leaves of the plants. It can also have translaminar action, meaning it can penetrate the leaves to control pests on the underside of the leaves as well.
