Abstract

The invention discloses a bactericidal composition containing a polygonum cuspidatum extract and pyraclostrobin. The effective active components are selected from the polygonum cuspidatum extract and the pyraclostrobin according to the weight ratio of 1:80-60:1. The bactericidal composition has synergistic effects on various diseases harming agricultural production, can reduce the dosage of pesticides and residual quantity of the pesticides on crops, reduces environmental pollution, is safe to human and animals, is good in environmental compatibility and is not liable to cause drug resistance in the diseases.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing polygonum cuspidatum extract and pyraclostrobin to crop diseases. Background technique [0002] Polygonum cuspidatum extract mainly contains emodin and emodin methyl ether, which is in a viscous state and is generally easy to make liquid preparations. However, liquid preparations usually contain organic solvents and are prone to phytotoxicity, so they can be used to prevent and control cucumber powdery mildew. [0003] Pyraclostrobin belongs to the methoxyacrylate fungicides and is widely used in crop diseases. [0004] However, in the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the ...
