Fastac EC Insecticide

Fastac® EC Insecticide gives growers an effective new tool with excellent knockdown, residual and repellent action. It works on a broad spectrum of piercing-sucking and chewing insect pests, including aphids, beetles and stink bugs. It’s also very cost-efficient because it tank-mixes* with fungicides like Priaxor® fungicide. Field trials show that, when used as part of a comprehensive pest management program, Fastac instecticide can help maximize yield potential.

How It Works

By acting on the nervous system of insects, the active in gradient in Fastac insecticide, alpha-cypermethrin, sustains succession of the nerve impulses which leads to over stimulation, exhaustion and death of the insect. Fastac insecticide will control a broad-spectrum of crop damaging pests, including aphids, beetles, armyworms and stink bugs. Fastac insecticide also boasts a low-dose rate and broad-crop label, which includes soybeans and cotton.
