Embodiment 1

[0064] Wash the whole plant of Brucea javanica, 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, extract with petroleum ether 5 times the volume of the plant powder, and collect The petroleum ether extract phase was concentrated under reduced pressure to obtain the extract; 15 kg of the extract was added to 70 kg of toluene, added to a mixing kettle with a stirrer and a thermometer, mixed for 1.5 hours at 50 ° C, and 3 kg of Tween (polysorbate) was added , 6-vinyldecyl aldehyde 4kg, sodium lauryl sulfate 2.5kg, benzylphenol polyoxyethylene ether 1.5kg, mix homogeneously, obtain the whole plant extract of Brucea javanica acaricide emulsifiable concentrate.

Embodiment 2

[0066] Wash the whole pig tooth soap plant, dry it in the shade in a ventilated place, grind it and pass it through a 40-60 mesh sieve; put the crushed plant powder into a multifunctional extraction tank, extract with petroleum ether 5 times the volume of the plant powder, and collect The petroleum ether extract phase was concentrated under reduced pressure to obtain the extract; 15 kg of the extract was added to 70 kg of toluene, added to a mixing kettle with a stirrer and a thermometer, mixed for 1.5 hours at 50 ° C, and 3 kg of Tween (polysorbate) was added , 4kg of 6-vinyldecyl aldehyde, 2.5kg of sodium lauryl sulfate, 1.5kg of benzylphenol polyoxyethylene ether, mix homogeneously, obtain the whole plant extract acaricide emulsifiable concentrate of pig tooth soap.

Embodiment 3

[0068] Wash the whole plant of Amorpha fruticosa, 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 15 kg of the extract and add 70 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-vinyl decanal, 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 Amorpha fruticosa.

Abstract

The invention relates to a botanical acaricide which is suitable for preventing and controlling harmful mites on cash crops such as fruit trees, vegetables, and the like, a preparation method and a use thereof. The botanical acaricide is prepared by adding surface active agent, emulsifier, osmotic agent, synergistic agent and the like onto the valid targets of Brucea javanica, Gleditsia sinensis or Amorpha fruticosa, and is characterized by high efficacy, low toxicity, lower residue, good compatibility with the environment, etc.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a botanical acaricide and a preparation method thereof. Background technique [0002] Herbivorous mites are important pests 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. The negative effects of chemical control are well known. At present, the research objects of botanical pesticides are mainly insects, and there is almost no research on mites; in the current domestic research of the same type, many botanical insecticide products have come out, but the pesticide products of botanical acaricides are not. None 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 developmen...
