The olive belongs to the genus Canarium of the family Burseraceae, is a famous fruit in tropical and subtropical regions, and has rich nutrient substances in pulp and calcium content as the head of the fruit. The psylla stellera is one of important insect pests of olives, and the psylla stellera inhales juice of tender leaves, tender buds and tender stems by adults and nymphs to inhibit the growth of new shoots, so that depression and small spots are formed on the leaf surfaces, the leaf color is dark green, the leaves become small and thin, a large amount of fallen leaves and fallen fruits are caused in serious conditions, the growth of plants is influenced, and the yield and the quality of the fruits are also influenced.
The existing chemical control is still one of important measures for controlling the psylla chinensis var olivaceus, but the generation number of the psylla chinensis var olivaceus is large, the generation amount is large, the medicine using times are large, the medicine using amount is large, the pesticide resistance is generated on various conventional chemical agents, and the control effect of the various chemical agents is reduced. Therefore, there is a need to develop new chemical agents.
The sulfur fluorine oxime ether is a non-ester oxime ether compound with independent intellectual property rights created by Hunan chemical research institute (national center for research on pesticide creation engineering technology). The molecular formula is as follows: c 23 H 21 ClFNOS, structural formula as follows.
The sulfur fluorine oxime ether has strong stomach toxicity and contact killing function to insects, can be used for preventing and controlling lepidoptera and homoptera insects on various crops, has low toxicity to people and livestock, and is safe to the crops.
The compounding of different pesticide active ingredients is one of the common effective means for delaying the drug resistance of plant diseases and insect pests, reducing the prevention and treatment cost, relieving the environmental pressure and developing novel medicaments. After different pesticide active ingredients are compounded, three action types can be shown: additive action, synergistic action and antagonistic action. The action types of different pesticide effective components after being compounded can be obtained only through a large number of tests. In most cases, the compounding of pesticide varieties is additive, and the compounding with the real synergistic effect is very little.
