[0043]

Embodiment 11～20

[0044] Embodiment 11~20 water dispersible granules

[0045] Pyrimidin, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. are crushed together by air flow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

Abstract

The invention discloses a bactericidal composition. The composition comprises an active component A and an active component B, wherein the active component A is selected from fenarimol, the active component B is any one component selected from the following compounds: polyoxins, ethirimol or salts thereof, tridemorph, and pyrimidine nucleotide antibiotics, and the weight ratio of the active component A to the active component B is from 1:80 to 60:1. The bactericidal composition has a synergetic effect on a plurality of diseases which harm the agricultural production, reduces the using amount of pesticide and the residual amount of pesticide on crops, relieves the environmental pollution, is safe to humans and livestock, has good environmental compatibility, and drug resistance of pests is not easy to generate.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a bactericidal composition on crop diseases. Background technique [0002] Fenarimol chemical name: 2,4'-dichloro-2-(pyrimidinyl-5) benzylmethanol, molecular formula: C 17 h 12 C l2 NO, a broad-spectrum fungicide with preventive and curative effects for foliar spraying. By interfering with the formation of pathogenic sterols and ergosterol, it affects normal development. The drug cannot inhibit the germination of pathogenic spores, but it can inhibit the growth and development of pathogenic mycelium, so that it cannot infect plant tissues. [0003] Polyoxin, pyrithrimol or its salts, tridemorpholine, and pyrimidine nucleoside antibiotics are commonly used fungicides and are widely used in crop diseases. Among them, the salt of pyrithrimol is pyrithrimol sulfonate , Pyrimidine nucleoside antibiotics, also known as agricultural anti-120. [0004] However, i...
