Hexythiazox has a broad insecticidal spectrum and has high acaricidal activity against mocking mites, panonychus mites, etc.

Hexythiazox is a thiadiazine insect growth regulator with high selectivity, strong contact effect and gastric toxicity. It has a good control effect on planthoppers, leafhoppers, whiteflies and scale insects. Some coleopteran pests and pest mites also have lasting larvicidal activity. It can effectively control planthoppers and leafhoppers on rice, leafhoppers on tea, potatoes, whiteflies on citrus, vegetables, shield scales and mealybugs on citrus. According to domestic research, it has a certain systemic transport effect on rice plants. Its mechanism of action is to inhibit the synthesis of insect chitin and interfere with the metabolism, causing the nymphs to fail to shed their skin, or deformed, or erupted and die slowly, and has high nymphicidal activity. Generally, the recommended dose cannot directly kill the adults, but it can reduce egg laying, lower egg hatching rate and shorten its lifespan. Generally, the effect can be seen only 3 to 7 days after application. It has no direct lethality on adults, but it can shorten its life span and reduce the amount of eggs laid, and most of the produced sterile eggs, even if the larvae hatch, they die quickly. It has a good control effect on planthoppers, leafhoppers, whiteflies and scale insects of the order Hemiptera. The efficacy period is more than 30 days. It is safer to natural enemies. Hexythiazox has no cross-resistance problem with other insecticides and has a good overall effect. The effect of the drug is slow, and the pest damage can be controlled 3 to 7 days after application. When the insect population density is high, it should be mixed with quick-acting agents.

Hexythiazox is also a thiazolidinone acaricide, which has good penetration into the epidermal layer of plants, but has no systemic conduction effect. It has strong egg-killing and juvenile-killing mites to various plant pests, and it is not effective to adult mites, but it has the effect of inhibiting hatching on the eggs laid by female adult mites exposed to the liquid medicine. This medicine is a non-temperature coefficient acaricide, with no significant difference in effect at different temperatures and a long residual effect. The medicine has good control effect on spider mites, but poor control effect on rust mites and gall mites. It is safe for crops at common concentrations and can be mixed with Bordeaux mixture, lime sulfur mixture and other pesticides.
