Embodiment 16～30

[0045] Embodiment 16~30 water dispersible granules

[0046] Penthiopyrad, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are air-pulverized together 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 an efficient bactericidal composition containing penthiopyrad, which is the bactericidal composition containing an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from penthiopyrad; the active ingredient B is selected from any one of the following compounds: cyprodinil, pyrimethanil, mepanipyrim, iprodione and procymidone; and a weight ratio of the active ingredient A to the active ingredient B is 1:80-60:1. The composition disclosed by the invention has synergism for various diseases damaging agricultural production, reduces dosage of pesticides, lowers residual quantity of pesticides on crops, relieves environmental pollution, and is safe to people and livestock, good in environmental compatibility and is less prone to generate drug resistance for diseases.

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 penthiopyrad on crop diseases. Background technique [0002] Penthiopyrad (Penthiopyrad) Chemical Name: (RS)-N-[2-(1,3-Dimethylbutyl)-3-thiophenolyl]-methyl-3-(trifluoromethyl)- 1H-pyrazole-4-carboxamide, molecular formula: C 16 h 20 f 3 N 3 OS, Penthiopyrad is a new type of amide fungicide developed by Mitsui Chemicals, Japan. It has a different bactericidal spectrum from the existing carboxamide fungicides, except that it is as effective as the existing carboxamide fungicides against basidiomycetes , which is also effective against Ascomycetes and Deuteromycetes, and is now recommended for the control of gray mold and powdery mildew that are resistant to other fungicides. [0003] Cyprodinil, pyrimethanil, azoxyprodil, iprodione, and procymidone are all commonly used fungicides and are widely used in...
