Problems solved by technology

[0002] A wettable powder containing thifensulfuron-methyl, which destroys the formation of new epidermis of insects, interferes with the normal growth and development of insects, and causes the death of pests. It has strong contact and stomach poisoning effects, and is permeable. Most of the powders in the prior art have poor drug properties. Strong and will cause damage to the environment, the manufacturing process is relatively complicated, in order to reduce production costs, improve product drug properties, high efficiency and energy saving, save time and effort, the present invention proposes a wettable powder containing 20% ​​thifensulfuron-methyl and its preparation method
