Abstract

The invention discloses an ametoctradin-containing bactericidal composition whose effective active components are active component A and active component B, wherein the active component A is selected from ametoctradin, the active component B is selected from any one of the following compounds: fluazinam, boscalid, fluopicolide, and ethaboxam, and the weight ratio of the active component A to the active component B is 1:70-70:1. The composition of the invention has high activity on various diseases of various crops, has significant synergistic effect, and has an extended bacteriocidal spectrum. The composition of the invention also has the characteristics of small dosage, rain wash resistance, and significant synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing pyraclostrobin on crop diseases. technical background [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] 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 synergistic, additive or antagonistic. In most cases, the compounding effects of pesticides are additive effects, and there are very few compoundings that really have synergistic effects, especially those...
