Embodiment 15～28

[0044] Embodiment 15~28 water dispersible granule

[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 containing fenarimol. The bactericidal composition contains an active component A and an active component B, wherein the active component A is fenarimol, the active component B is any one compound selected from the group consisting of carbendazim, thiophanate-methyl, prochloraz or a salt thereof and triflumizole, and a weight ratio of the active component A to the active component B is 1: 80 to 60: 1. The bactericidal composition exerts a synergistic effect on a plurality of diseases doing harm to agricultural production, reduces the usage amount of a pesticide and residual quantity of the pesticide on crops, mitigates environmental pollution, is safe to human beings and livestock, has good environmental acceptability and enables diseases not to easily generate drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing chloropyrimidin on crop diseases. Background technique [0002] Fenarimol chemical name: 2,4'-dichloro-2-(pyrimidinyl-5) benzylmethanol, molecular formula: C 17 h 12 C 12 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] Carbendazim, thiophanate-methyl, prochloraz, and flufenazole are all commonly used fungicides. The salts of prochloraz include: prochloraz manganese salt, prochloraz copper salt, prochloraz zinc salt, widely used applied to crop diseases. [0004] However, in the actual process of ag...
