Abstract

The invention discloses a pesticide composition containing polygonum cuspidatum extract and triazoles, a bactericidal composition containing an active ingredient A and an active ingredient B, wherein the active ingredient A is the polygonum cuspidatum extract, the active ingredient B is selected from any of the following compounds: hexaconazole, epoxiconazole, difenoconazole and propiconazole, and the weight ratio of the active ingredient A to the active ingredient B is 1: 80 to 80: 1. The composition disclosed by the invention has a synergistic effect for various diseases harmful for agricultural production, so that the using amount of pesticides is reduced, the residual quantity of the pesticides on crops is reduced, the environmental pollution is alleviated, the composition is safe for people and livestock and good in environmental compatibility, and resistance to drugs is unlikely to occur for the diseases.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition containing Polygonum cuspidatum extract and triazoles on crop diseases. Background technique [0002] Polygonum cuspidatum extract (sedaxane), this product is the stem and root of Polygonumcuspidatum Sieb.etZucc, which is an important traditional Chinese medicine in my country; the extract of Polygonum cuspidatum mainly contains emodin and emodin methyl ether, which is in a viscous state , has special effects on the control of cucumber powdery mildew. [0003] Hexaconazole, econazole, difenoconazole or propiconazole are all triazole 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...
