Problems solved by technology

[0002] Herbivorous mites are important harmful mites in agricultural production. They have a wide distribution range, many harmful hosts, a large area of ​​occurrence, and strong drug resistance. They cause serious losses to agricultural production and are difficult to control.
At present, the research objects of botanical pesticides are mainly insects, and there are few studies on mites; in the current domestic similar research, many botanical insecticide products have come out, but the pesticide products of botanical acaricides Less reported

Embodiment 1

[0067] Wash the whole plant of Fructus Xanthii, dry it in the shade in a ventilated place, grind it and pass through a 40-60 mesh sieve; put the crushed plant powder into a multifunctional extraction tank, and extract it with petroleum ether with 5 times the volume of the plant powder. Collect the petroleum ether extract phase, concentrate under reduced pressure to obtain the extract; take 20 kg of the extract, add 75 kg of toluene, add it to a mixing kettle with a stirrer and a thermometer, mix for 1.5 hours at 50 ° C, add Tween (polysorbate) 3kg, 4kg of 6-vinyldecyl aldehyde, 2.5kg of sodium lauryl sulfate, and 1.5kg of benzylphenol polyoxyethylene ether were mixed uniformly to obtain the acaricide emulsifiable concentrate of the whole plant extract of Xanthium officinalis.

Description

technical field [0001] The present invention relates to pesticides and their preparation methods, in particular to botanical acaricides and their preparation methods. Background technique [0002] Herbivorous mites are important harmful mites in agricultural production. They have a wide distribution range, many harmful hosts, a large area of ​​occurrence, and strong drug resistance. They cause serious losses to agricultural production and are difficult to control. At present, the research objects of botanical pesticides are mainly insects, and there are few studies on mites; in the current domestic similar research, many botanical insecticide products have come out, but the pesticide products of botanical acaricides Less reported. It can be seen that the use of biological pesticides to control the harm of herbivorous mites, reduce the residues of pesticides in agricultural products, and the development of pollution-free botanical acaricides are imminent.
