Abstract

The invention discloses wettable powder for preventing and controlling wheat blossom midges. The wettable powder is prepared from, by weight, 30-40 parts of castor oil plants, 25-35 parts of angled bittersweet, 15-20 parts of herb of cynanchum komarovii, 15-20 parts of red-knees herb, 15-20 parts of Chinese honeylocust fruit, 5-8 parts of a surfactant, 6-10 parts of a wetting agent and 90-110 parts of filler. According to the wettable powder, the raw materials are plants and are wide in source; all the raw materials cooperate with one another kill pests, and therefore the pesticidal effect is significant; the wettable powder has no pesticide resistance and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural insecticide, in particular to a wettable powder for controlling wheat midge and a preparation method thereof. Background technique [0002] Wheat midge is a destructive pest, belonging to the family Diptera, and it specializes in sucking the slurry in wheat grains, causing hollowness. Moreover, wheat midge is small in size and hidden in danger. When the harm is often discovered, the best period for prevention and control is often missed. If it is not good, it will cause a substantial reduction in wheat production. Commonly used chemical agents for the control of wheat midges include chlorpyrifos, omethoate, phoxim, chlorofluorocyanide, etc. However, the long-term and frequent application of chemical pesticides to control wheat midges will seriously affect the balance of the farmland ecosystem and cause the population of natural enemies in the wheat field to decline , pest damage is aggravate...
