Permethrin APPLICATIONS
Mode of action Non-systemic insecticide with contact and stomach action, having a slight repellent effect. Uses A contact insecticide effective against a broad range of pests. It controls leaf- and fruit-eating Lepidoptera and Coleoptera in cotton, at 100-150 g a.i./ha, in fruit, at 25-50 g/ha, in tobacco, vines and other crops, at 50-200 g/ha, and in vegetables, at 40-70 g/ha. It has good residual activity on treated plants. It is effective against a wide range of animal ectoparasites, provides >60 d residual control of biting flies in animal housing, at 200 mg a.i. (as EC)/m2 wall or 30 mg a.i.
