Mechanism of action
Chlorpyrifos has an enteric, contact and fumigant action. It decreases the activity of acetylcholine esterase, an important zymoprotein involved in nerve impulse transmission. It results in tremor with subsequent paralysis. It shows a quick (seconds to minutes) and long-term (up to 2 weeks) protective effect. It eliminates pests at all stages of their development (egg, larvae, imago) and remains highly effective at both low and high temperatures.
Bifenthrin has an acute contact enteric action and affects the nervous system by blocking sodium channels. It effectively inhibits the development of pests, including Coleoptera, Orthoptera, Diptera, and Lepidoptera orders, as well as some mites. Has repellent properties. Has a rapid toxic (knockdown) and long-term residual effect, up to 20-30 days.
Both components complement and reinforce each other's effect (synergism). It ensures high efficacy of the product against a wide range of pests of main agricultural crops. The product contains two active ingredients of different chemical classes, so resistance is highly unlikely.
Protective effect period
Not less than 14 days.
Rate of exposure
High. Visible signs of damage to pests are observed in 30 minutes (knockdown effect). Death in 2-5 hours
