Abstract
The invention discloses a bronopol-containing bactericidal composition. The bactericidal composition contains an active ingredient A and an active ingredient B, the active ingredient A is selected from bronopol, the active ingredient B is any one compound selected from the following compounds: copper oxychloride, cuppric nonyl phenolsulfonate, oxine-copper, kasugamycin, validamycin, moroxydine hydrochloride, polyoxin, copper(succinate+glutarate+adipate), zhongshengmycin, xinjunan acetate, and zinc thiazole, and the weight ratio of the active ingredient A to the active ingredient B is 1:70 to 70:1. The composition provided by the invention has higher activity on various diseases of a plurality of crops, and an obvious synergistic effect, enlarges the bactericidal spectrum, and has the characteristics of a small medicine using amount, resistance to rain erosion, and an obvious synergistic effect.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing bronopol to crop diseases. technical background [0002] Bronopol (bronopol) 2-bromo-2-nitro-1,3-propanediol, C 3 h 6 BrNO 4 , Control a variety of plant pathogenic bacteria. [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 with very obvious synergistic effects and high synergistic ratios. Aft...
