Abstract

The invention discloses a fungicidal composition containing ametoctradin. The fungicidal composition contains 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 the following compounds: thiophanate-methyl, cyazofamid, triflumizole, fenamidone, carbendazim, prochloraz and salts thereof, and the weight ratio of the active ingredient A to the active ingredient B is (1: 80)-(80: 1). The composition disclosed by the invention has synergy against a variety of diseases in agricultural production, and can reduce the dosage of a pesticide, reduce the residual amount of the pesticide on crops, reduce environmental pollution, realize safety to people and animals and good environmental compatibility and enable the diseases to be less prone to producing drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing pyraclostrobin 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] Thiophanazim-methyl, Cyazofamid, Flufenazole, Metraflux, Carbendazim, Prochloraz or their salts are all commonly used fungicides, which are widely used in crop diseases, and the salts of prochloraz include prochloraz Chloridine manganese salt, prochloraz copper salt, prochloraz zinc salt. [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 ar...
