Abstract

The invention relates to the application of gallnut extract as the antiseptic and antiseptic containing the gallnut extract. The gallnut extract mainly comprises at least one of the following extracted compounds: Chinese tannin, five gallanilide glucose (1, 2, 3, 4 and 6-Five-O- gallanilide-Beta-D-glucose) and multiply gallanilide glucose (Six or Seven to twevel gallanilide glucose). The invention has good effects for preventing and curing a plurality of crop diseases and is good for environment, which is characterized by low residue, high prevention effect, a plurality of action points and difficulty of generating drug resistance for germina.

Description

【Technical field】 [0001] The present invention relates to the application of the gallnut extract as a fungicide, and to an agricultural fungicide containing the gallnut extract as an active ingredient. 【Background technique】 [0002] Plant diseases are an important factor for crop yield reduction, so it is necessary to use a large amount of pesticides every year for disease control to recover crop yield loss. In recent years, the harm of diseases to crops has become more and more serious. Due to the abuse of pesticides, pathogenic bacteria have become more and more resistant to pesticides, resulting in a decrease in the control effect year by year. At the same time, due to excessive application of pesticides, a certain degree of pollution to the environment . Therefore, there is an urgent need to develop pesticide varieties with better disease control effects and environmental compatibility. [0003] It has always been the goal of people to apply plant extracts that can ef...
