Abstract

The invention relates to the technical field of pesticides, and discloses a pesticide for preventing and controlling litchi whiteflies and a preparation method thereof. The pesticide is prepared from, by weight, 12-32 parts of sisyrinchium rosulatum volatile oil, 9-19 parts of cypermethrin, 9-15 parts of a rosemary extract, 11-23 parts of bergamot oil, 6-17 parts of herba portulacae, 4-15 parts of green Chinese onions, 4-12 parts of neem tree flowers, 30-45 parts of vegetable oil, 8-15 parts of cosolvent and 6-14 parts of a surfactant. According to the pesticide, the litchi whiteflies can be effectively prevented and controlled, and the litchi yield can be effectively increased; meanwhile, the pesticide liquid residue period of the pesticide is only 8-11 days, and therefore the pesticide is safe to people and livestock. The invention further provides the preparation method of the pesticide for preventing and controlling the litchi whiteflies. The pesticide for preventing and controlling the litchi whiteflies is reasonable in compatibility, high in litchi whitefly prevention effect, short in killing time, green and nuisanceless, greatly decreases the pest cardinal numbers and has a great advantage on litchi whitefly prevention and control.
