Abstract

The invention discloses a bactericidal composition containing a polygonum cuspidatum extract and azoxystrobin or kresoxim-methyl, which contains an active component A and an active component B. The active component A is the polygonum cuspidatum extract and the active component B is one selected from the following components: azoxystrobin and kresoxim-methyl. The weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a synergistic effect on various diseases damaging agricultural production, reduces dosage of a pesticide and reduces residual quantity of the pesticide on crops, reduces environment pollution, is safe to people and animal, is good in environmental compatibility and is not liable to generate drug resistance of 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 azoxystrobin or kresoxim-methyl 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] Azoxystrobin and kresoxim-methyl belong to methoxyacrylate fungicides, which are 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...
