Problems solved by technology

[0003] It has always been the pursuit of researchers to apply plant extracts that can effectively control the growth of plant pathogens to agricultural disease control, or mix them with other fungicidal compounds to minimize pesticide residues and provide safer and more effective agrochemical products , but the existing fungicides are not satisfactory in terms of bactericidal activity and residue

Abstract

An application of scutellaria root extract in preparing the agricultural bactericide for preventing and eliminating the diseases and bacteria of agricultural crops is disclosed. Said agricultural bactericide contains the extract of scutellaria root and the active component chosen from pyrimethanil, diethofencarb and procymidone. Its advantages are high effect, friendly to environment, and broad spectrum.

Description

【Technical field】 [0001] The present invention relates to the application of the scutellaria baicalensis extract as an agricultural fungicide, and relates to the agricultural bactericidal composition containing the combination of the scutellaria baicalensis extract and pyrimethanil, diptofencarb or procymidone as active ingredients. 【Background technique】 [0002] Due to the huge loss of crop yield due to pests and diseases of crops, it is necessary to apply a large amount of pesticides every year for pest control to recover the loss of crop yield. In recent years, pests and diseases have become more and more harmful to crops, and due to the abuse of pesticides, crop pathogens have become more and more resistant to pesticides, resulting in a decrease in the effectiveness of pest control year by year. cause a certain degree of pollution. Therefore, there is still a need for pesticide varieties with better pathogen control effects. [0003] It has always been the pursuit of ...
