Abstract

The invention relates to the technical field of pesticide and discloses a pesticide for preventing and controlling Sphecosesia litchivora and a preparation method thereof. The pesticide is prepared from 12 to 22 parts by weight of volatile oil of Wedelia trilobata, 8 to 17 parts by weight of dichlorvos, 8 to 14 parts by wieght of extract of Artemisia scoparia, 12 to 22 parts by weight of bergamot oil, 7 to 14 parts by weight of purslane, 4 to 13 parts by wieght of green onion, 3 to 12 parts by weight of neem flowers, 35 to 46 parts by weight of vegetable oil, 7 to 13 parts by weight of a co-solvent and 3 to 13 parts by weight of a surfactant. The pesticide can effectively prevent and control Sphecosesia litchivora so that a lychee yield is improved. The pesticide has a residue period of only 8 to 10 days and human and animal safety is guaranteed. The invention also provides the preparation method of the pesticide for preventing and controlling Sphecosesia litchivora. The pesticide has a reasonable formula, has good Sphecosesia litchivora prevention and control effects, has short killing time, is environmentally friendly and harmless, greatly reduces injurious insect base and has a great advantage in prevention and control of Sphecosesia litchivora.
