Pyrethroids are a class of broad-spectrum insecticides that can control a variety of pests, and their insecticidal toxicity is 10 to 100 times higher than that of older generation insecticides such as organochlorine, organophosphorus, and carbamate. Pyrethroids have a strong contact killing effect on insects, and some varieties have both stomach poisoning or fumigation effects, but none of them have systemic effects. Its mechanism of action is to disturb the normal physiology of insect nerves, causing them to die from excitement, spasm, and paralysis. Due to the small dosage and low concentration of pyrethroids, it is safer for humans and animals and has little pollution to the environment. The main disadvantage is that it is highly toxic to fish, and it is also harmful to some beneficial insects. Long-term repeated use will also cause pests to develop drug resistance.
