Phenbutyltin is a kind of long-acting obligate acaricide, which is not cross-resistant to organophosphorus and chlorine-resistant mites. After spraying, the initial toxicity was slow, and the activity began to increase after 3 days and reached a peak at 14 days. The residual period of the drug is a longer one of the acaricides, up to 2 to 5 months, and the lethality of juvenile mites, mites and adult mites is relatively strong, but the lethality of eggs is not large. It is very safe to use in each growth period of the plant, and no drug harm occurs when the effective acaricidal concentration is more than 1 times. It has little effect on the natural enemies of mites, the predators of mites, the bailing armour and the grass bells. Phenylbutyltin is a temperature sensitive acaricide, its efficacy increases when the temperature is above 22 degrees, its activity decreases below 22 degrees, and its efficacy is worse below 15 degrees, so it should not be used in winter.
