Description

technical field

[0001] The invention belongs to the field of new pesticide creation, relates to a series of novel trichoderma derivatives, and also relates to the inhibitory effect of active ingredients of the series of compounds on plant pathogenic bacteria. Background technique

[0002] Plant diseases cause huge losses to crop yields every year. Although there are various methods and measures to control plant diseases, fungicides still play an important role in the integrated control of plant diseases. Many chemical fungicides commonly used at present have the characteristics of broad spectrum, high efficiency and low toxicity, which significantly improves the effect of fungicides in controlling plant diseases. However, some chemical fungicides have problems such as drug resistance and cumulative pollution to the environment and food. Therefore, the research and development of biological pesticides, especially the search and development of new fungicides from natural plant...
