Problems solved by technology

[0002] In daily life, the transportation of vegetables is becoming more and more common, and the deworming treatment of vegetables during transportation has become particularly important. Today, as early as the advocacy of green and environmental protection, many highly toxic and high residue chemicals have been limited or discontinued. Organic phosphorus Pyrethroids, pyrethroids, benzoylureas, and biochemical pesticides have reduced the original toxicity to a certain extent through the combination of pesticides, but due to the results of years of use, the insects' drug resistance and drug resistance have increased year by year. Strengthening, the effect of alternate use is not ideal, the actual dilution of pesticides and insecticides has far exceeded their limited range, and the chemical residues in agricultural products are far from meeting the requirements of pollution-free. The increasing demand for pesticides has caused rural environmental pollution The aggravation of its residues on the human body can not be ignored

Abstract

The invention discloses a liquid pesticide for green vegetables. The liquid pesticide is prepared from the following raw materials in parts by mass: 0.9-1.1 parts of orange peel, 0.5-0.8 parts of radix sophorae flavescentis, 0.9-1.1 parts of cortex meliae, 1.8-2.2 parts of pink plumepoppy herbs, 3-5 parts of herba houttuyniae, 1-3 parts of pericyclivine and 2-3 parts of spinosad. The invention also discloses a preparation method of the liquid pesticide. The liquid pesticide has the advantages that: firstly, natural herbal plant extracts are selected as raw materials, and the liquid pesticide can effectively realize the pesticide effect, and is environmentally friendly and free of public hazards; secondly, the liquid insecticide is convenient to prepare and use.
