Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of flocculation, deposition and precipitation that occur during the use of the above-mentioned flying control medicine in the prior art, block the nozzle, reduce the efficacy of the medicine, cause phytotoxicity, and cause poor control effect in the field. Brucea javanica oil is a special pesticide for aerial protection. The physical properties of the liquid medicine of this special aerial pesticide are different from those of the existing aerial control medicines. The formation of small mist droplets leads to the formation of larger mist droplets, which accelerates the settlement of the liquid medicine, has a significant anti-drift effect, and has obvious medicinal effects in the field

Abstract

The invention discloses a special farm chemical containing oleum fructus bruceae for aerial spraying. The farm chemical comprises, by weight, 0.2-40% of a farm chemical active agent, 5-20% of a surfactant, 5-20% of a cosolvent, and 0.01-1% of an antioxidant, with the balance being oleum fructus bruceae. Compared with the prior art, the special farm chemical for aerial spraying has the advantages that the anti-drifting effect is obvious, and the field farm chemical effect is obvious.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a special pesticide for aerial defense containing javanica javanica oil and a preparation method thereof. Background technique [0002] Flying plant protection is a fast-growing new thing. In 2018, my country had 40,000 agricultural drones. The area of ​​farmland used for agricultural drones for pest and disease control exceeded 100 million mu, and the operating area was 260 million mu. Has become the general trend. However, apart from the lack of special pesticides suitable for aerial control, another problem faced by aerial control plant protection is that aerial control is sprayed over a large area, which attacks pests and natural enemies indiscriminately. This is different from the plant protection policy of integrated agricultural control. Paradoxical. On the other hand, unlike the traditional spraying method, aerial pesticides are high-concentration sprays, which ...
