The invention further provides a method and process for quickly gathering the effective ingredients in the dicranostigma leptopodum.

Description

technical field [0001] The invention relates to a plant-derived medicine for resisting plant pathogenic bacteria, in particular to an extract of bald acne flower and its extraction method and application. Background technique [0002] Phytopathogenic bacteria have a very serious impact on the healthy growth and development of plants, the yield and quality of crops. Therefore, the application of plant fungicides is of great significance in modern agriculture. However, long-term repeated use of the same fungicide has resulted in strong resistance of plant pathogens to many current plant fungicides. In addition, many countries have banned the use of some agricultural fungicides that have adverse effects on the environment, people or ecology. Therefore, it is of great significance to research and develop new plant fungicides with high efficiency, low toxicity and environmental protection. [0003] Biopesticide is the hottest field of new pesticide research today, and botanica...
