Abstract

The invention discloses a sterilization composition containing ametoctradin and methoxyacrylates. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from ametoctradin; the active ingredient B is selected from any one of compounds as follows: azoxystrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, metominostrobin and pyraoxystrobin; the weight ratio of the active ingredient A to the active ingredient B is (1: 80) to (80: 1). According to the composition, a synergistic effect on various diseases harmful to agricultural production is achieved, the pesticide dose is reduced, the pesticide residues on crops are reduced, the environmental pollution is alleviated, the harm cannot be caused to human and livestock, the environmental compatibility is good, and the pesticide resistance cannot be easily generated for 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 pyraclostrobin and methoxyacrylate to crop diseases. Background technique [0002] Ametoctradin (ametoctradin) has obtained provisional registration in China. Ametoctradin is a new triazole pyrimidine fungicide for the control of downy mildew in cucumber and grape crops. [0003] Azoxystrobin, kysstrobin, kysstrobin, orysastrobin, fenoxystrobin or pyraclostrobin are all 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 compounded, and according to the actual application effect, it is judged whether a certain compound is synergi...
