Problems solved by technology

[0003] At present, the commonly used whitefly control agents have high insecticidal activity against adults, but the control effect on eggs is low or even ineffective. However, whitefly has high egg production and rapid reproduction speed. At the same time, whitefly All three forms exist, including eggs, nymphs, and adults. Many farmers only kill the adults while ignoring the eggs. This causes the next wave of whiteflies to rise again within a few days after spraying. Field control Difficult effect is poor

Abstract

The invention discloses an insecticide composition for bemisia tabaci. The insecticide composition is prepared by compounding a bemisia tabaci insecticide and chlorbenzuron, wherein the bemisia tabaciinsecticide is any one of nitenpyram, spinosad and acetamiprid. The bemisia tabaci insecticide and the chlorbenzuron are compounded to obtain the insecticide composition, and through the complementarity of the two insecticides, bemisia tabaci adults and eggs in the field are killed at the same time, so that the prevention and processing effect of the bemisia tabaci in the field can be obviously improved.

Description

technical field [0001] The invention relates to the prevention and control of whitefly, in particular to an insecticide composition which has a synergistic effect on the control of whitefly. Background technique [0002] Bemisia tabaci (Gennadius) is a global pest that seriously endangers agricultural production. Because the body surface of whitefly is covered with wax, it is difficult to control, it is easy to produce drug resistance, the reproduction speed is fast, and the generation overlap is serious. Therefore, field control It is more difficult, and chemical control is still the main control measure for whitefly. [0003] At present, the commonly used whitefly control agents have high insecticidal activity against adults, but the control effect on eggs is low or even ineffective. However, whitefly has high egg production and rapid reproduction speed. At the same time, whitefly All three forms exist, including eggs, nymphs, and adults. Many farmers only kill the adults...
