Abstract

The invention discloses a high efficient sterilizing composition containing initium. The composition comprises an active component A and an active component B, wherein the active component A is initium, the active component B is selected from one of the following components: metalaxyl, metalaxyl-M, propamocarb, salts of propamocarb, cymoxanil, and iprovalicarb, and the weight ratio of the active component A to the active component B is 1:80 to 60:1. The composition has high activity on a plurality of diseases on a plurality of crops, has prominent synergetic effect at the same time, and thus the bactericidal spectrum is enlarged. Moreover the composition has the characteristics of little use amount, rain washing resistance, and prominent synergetic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition containing pyraclostrobin to 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] The salt of propamocarb is propamocarb hydrochloride or propamocarb ethyl phosphate. [0004] 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...
