Abstract

The invention relates to the technical field of pesticides, and discloses a pesticide for preventing and treating litchi stinkbug and a preparation method thereof. The pesticide is prepared from the following raw materials in parts by weight: 8-17 parts of Sphagneticola trilobata volatile oil, 7-16 parts of cypermethrin, 5-12 parts of Melia azedarach extract, 11-20 parts of bergamot oil, 5-13 parts of purslane, 3-12 parts of scallion, 2-10 parts of Azadirachta indica flower, 32-42 parts of vegetable oil, 6-12 parts of cosolvent and 2-12 parts of surfactant. The pesticide can effectively prevent and treat litchi stinkbug and enhance the litchi yield. The residual life of the pesticide liquor is only 7-10 days, so the liquor is safe for people and livestock. The invention also discloses a preparation method of the pesticide for preventing and treating litchi stinkbug. The pesticide for preventing and treating litchi stinkbug has the advantages of high litchi stinkbug prevention effect, short killing time and no pollution, greatly reduces the base number of pest population, and has huge advantages in preventing and treating litchi stinkbug.
