Aqueous berberine-matrine fungicidal and insecticidal solution

Abstract

The invention discloses a plant pesticide composition, which mainly contains 0.5%-2.5% of berberine and 0.1-2.0% of matrine. The invention is mainly used for preventing and controlling pests such as armyworm and killing bacteria and the like. The invention is a botanical pesticide with high efficacy, low toxicity to humans and animals, and no environmental pollution.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and in particular relates to a berberine and matrine bactericidal and insecticidal water agent. Background technique [0002] Plant diseases and insect pests cause huge losses to agricultural production every year. The common control method is the application of chemical pesticides. However, chemical pesticides have the disadvantages of polluting the environment, prone to insect resistance, and being toxic to humans and animals. They have caused great harm to the environment and human health. Therefore, the development and utilization of pesticide resources that are harmless to the environment and human beings have attracted more and more attention from various countries. Botanical pesticides are extracted from natural plants and have a control effect on germs and insects. Pesticides with low toxicity to humans and animals can also delay the emergence of insect resistance, so they are ideal t...

Problems solved by technology

In recent years, there have been many developments of insecticides with matrine and oxymatrine as the main components, such as the domestic 0.6% matrine nicotine emulsifiable oil (Pesticide Factory of Henan Huaxian Wuxing Industrial Group Company), the patent "Bitrine Caffeine cypermethrin mixture and its manufacture method "(patent No. is ZL96109680.2), 1% matrine alcohol solution (Inner Mongolia Chifeng Bizhou Plant Pesticide Factory), but lack of development of plant pesticides in bactericidal aspect, berberine has been used for many years It has been used to prevent and treat dysentery. The main physiologically active component of Coptis chinensis is berberine. Berberine is widely distributed in nature, such as the genus Coptis and Tangsong of Ranunculaceae, the genus Gushanlong of Fangji family, and the phellodendron of Rutaceae. Berberis genus, Berberis genus and Shigonggong genus and other plants of Berberidaceae all exist, mainly used in traditional Chinese medicine to treat diseases, and the effect on plant insecticide and bactericidal has not been reported yet; the botanical pesticides produced in China at present, Generally, the control effect is low, the drug effect is slow, and the dilution factor is low, so there is an urgent need for new botanical insecticides and fungicides with high drug efficacy
