Thiazide is a thiazidazone insecticide, as one of the most successful insect growth regulator products (IGRs) in the world, it can effectively control homoptera pests (such as rice planthoppers, whiteflies, ticks, etc.) and is widely used in more than 80 countries and regions around the world.
Thiazinone is an inhibitor of chitin synthesis. Because of its unique mechanism of action, strong selectivity and beneficial biosafety at recommended doses, it is often used as one of the essential agents for rotation schemes and is widely used in integrated pest management (IPM). At the moment when highly toxic pesticide varieties are banned and the resistance of conventional pesticide varieties is developing, thiazinone has ushered in a new round of development opportunities.
Mechanism of action and composition characteristics:
Thiazinone is a chitin synthesis inhibitor type 1, which is classified as class 16 due to the large differences between structure and insecticidal profile and benzoylurea insecticides (class 15: chitin synthesis inhibitor type 0).
Thiazide ketone has a strong contact killing effect and a certain gastric toxicity effect on homoptera pests, and does not absorb internal conduction in plants, but has a certain permeability and can be absorbed by leaves or leaf sheaths. For nymphs, the death of the nymphs is caused by inhibition of molting, and the lower the age of the pest, the higher the efficacy is; the recommended dose generally has no direct killing effect on adults, but the number of pest populations can be controlled by shortening the lifespan of adults, inhibiting female egg laying, and reducing egg hatching rate.
Under normal conditions of use, thiazide is harmless to most beneficial organisms, such as those of the order Venomycephalus (grasshoppers) and hymenoptera (parasitic wasps), and with the help of natural predators, can further help control the population of pests. On the other hand, since thiazide ketone is basically ineffective against Lepidoptera and Taenoptera insects, it is not suitable for the control of this type of pest.
Domestic and foreign applications:
Thiazinone is used in a wide range of crops. It is suitable for rice, citrus, apple, grape, cotton, tea, mango, eggplant and other crops. However, it cannot be used for cabbage and turnips.
The control objects are mainly homoptera pests (rice planthoppers, whitefly and tick shell insects), after the prohibition of phosphorus killing, the application of citrus and other fruit trees showed a rapid upward trend, the main control targets are the general family of ants, shields and mealybugs, etc., specifically citrus yasichoppers and other crusts, peach, plum, apricot tree mulberry white borer, jujube tree Japanese turtle wax borer and so on. At the same time, it can control whitefly on vegetables and leafhoppers on tea trees. Thiazide ketone has also been reported to have inhibitory effects on specific species of tick mite pests, such as tea yellow mites.
