||Description: ALPHACYPERMETHRIN is a synthetic pyrethroid insecticide. It is a racemic mixture of two isomers (1R Cis S and 1S Cis R isomers) out of the eight Cypermethrin isomers. It is two to three times more active than Cypermethrin under field conditions. It is effective on a wide range of insects in a variety of crops. Alphacypermethrin has contact and stomach action and can be used on cereals, cotton, fruits, vegetables, flower crops, oilseeds, sugar beet, tea, tobacco, vines, etc. for the control of a variety of insects.
