Description

technical field

[0001] The invention relates to the technical field of fungal disease control. Background technique

[0002] Fungal diseases of tea trees are a kind of diseases that can obviously harm the growth of tea trees or the quality of tea leaves. Among them, the most common tea tree fungi include Colletotrichum sp., Fusarium sp. and Phomasp., etc., which are easy to occur in large areas in alpine tea gardens, and often harm tea tree buds, leaves, stems and roots, causing extreme damage. large economic loss.

[0003] At present, the prevention and treatment of fungal diseases of tea is still dominated by chemical control, such as the fungicide shenzimycin, which is a compound fungicide that is preferred in tea production. Shenzimycin is a kind of biological source pesticide with high efficiency, low toxicity and good environmental compatibility. However, excessive use of this drug will easily cause the bacteria to develop resistance and drug resistance to a single ...
