The invention provides a dispersible oil suspending agent containing kojic acid and cyantraniliprole, a preparation method and application thereof, relating to the technical field of pesticides, and the dispersible oil suspending agent containing kojic acid and cyantraniliprole comprises the following components in percentage by weight: 10-20% of kojic acid, 5-20% of cyantraniliprole, 10-30% of emulsifier, 1-5% of dispersant, 1-4% of tackifier and the balance of dispersion medium to 100%. The pesticide provided by the invention can kill diseases and pests such as thrips, plutella xylostella, aphids, locusts, cabbage caterpillars and the like of crops, is not easy to generate cross resistance, and has longer lasting period.
Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a dispersible oil suspending agent containing kojic acid and cyantraniliprole, and a preparation method and application thereof.
Background
Thrips occur all the year round, mainly in open field in spring, summer and autumn, and in greenhouse in winter, and damage crops such as eggplant, cucumber, kidney bean, pepper, watermelon and the like. The peak period is 11-12 months in autumn or winter, and 3-5 months is the second peak period. The female imagoes mainly carry out parthenogenesis, have stronger reproductive capacity, and can be quickly killed by the traditional pesticide.
Diamondback moth, aphid, locust, cabbage caterpillar and the like also seriously affect the growth of crops, and the traditional pesticide is difficult to kill the thrips, the diamondback moth, the aphid, the locust, the cabbage caterpillar and the like together, and the lasting period of the pesticide is short.
Disclosure of Invention
The invention aims to provide a dispersible oil suspending agent containing kojic acid and cyantraniliprole, which can kill diseases and pests of crops such as thrips, diamondback moths, aphids, locusts, cabbage caterpillars and the like, is not easy to generate cross resistance and has longer lasting period of the drug.
The invention is realized by the following method:
the dispersible oil suspending agent containing kojic acid and cyantraniliprole comprises the following components in percentage by weight: 10-20% of kojic acid, 5-20% of cyantraniliprole, 10-30% of emulsifier, 1-5% of dispersant, 1-4% of tackifier and the balance of dispersion medium to 100%.
Preferably, the emulsifier is one or more of phenethyl nonylphenol polyoxyethylene ether, calcium dodecylbenzene sulfonate, fatty alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether, alkylphenol polyoxyethylene ether and castor oil polyoxyethylene ether.
Preferably, the dispersant is one or more of polycarboxylate, lignosulfonate, alkyl naphthalene sulfonate and alkylaryl polyoxyethylene ether phosphate.
Preferably, the tackifier is one or more of white carbon black, magnesium aluminum silicate and organic bentonite.
Preferably, the dispersion medium is one of soybean oil, corn oil, rapeseed oil, mineral oil and methyl oleate.
The preparation method of the dispersible oil suspending agent containing kojic acid and cyantraniliprole comprises the following processes:
(1) weighing the dispersion medium, the emulsifier and the dispersant according to the proportion, putting the mixture into a feeding kettle, and fully and uniformly stirring the mixture;
(2) weighing kojic acid, cyantraniliprole, a thickening agent and a tackifier according to a ratio, putting into a feeding kettle, and uniformly stirring with the raw materials in the step (1);
(3) and (3) placing the mixed liquid obtained in the step (2) into a sand mill for sanding, introducing condensed water, and discharging after the particle size is qualified to be detected to obtain the dispersible oil suspending agent.
Application of a dispersible oil suspending agent containing kojic acid and cyantraniliprole in preventing and treating crop thrips, diamondback moths, aphids, locusts and cabbage caterpillars, in particular to preventing and treating thrips on hot peppers.
The invention has the beneficial effects that:
the dispersible oil suspending agent containing kojic acid and cyantraniliprole and the preparation method thereof provided by the invention have the following advantages:
1. the main component of the invention is kojic acid which is an organic acid with antibacterial action, compared with chemical pesticides, the invention has no toxic or side effect, is environment-friendly and more environment-friendly, and the resistance of insects to kojic acid and cyantraniliprole has no mutual resistance with other various insecticides with different types and different action mechanisms, and the combination of the two increases the toxicity of the cyantraniliprole, increases the control range, and the combination with the cyantraniliprole not only is not easy to generate the mutual resistance, but also is easy to be absorbed by plants and improves the lasting period.
The dispersible oil suspending agent is more environment-friendly compared with other formulations on the market, the dispersing medium is one of soybean oil, corn oil, rapeseed oil, mineral oil and methyl oleate, the raw material is simple and easy to purchase, and the prepared oil suspending agent has a certain synergistic effect, and has the advantages of strong permeability, high adhesiveness, good rain erosion resistance, good moisture retention and long lasting period.

FIG. 1 is a flow chart of the manufacturing process of the present invention.
Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings.
