Embodiment 1～19
[0040] Embodiment 1~19 wettable powder
[0041] Mix penthiopyrad, active ingredient B, dispersant, wetting agent, and filler in a mixing tank, pulverize them with a jet mill, and then mix them evenly to obtain the wettable powder product of the present invention. For details, see Table 1. Table 1 Embodiment 1~19 each component and parts by weight
[0042]
[0043]
Embodiment 20～38
[0044] Embodiment 20~38 water dispersible granules
[0045]Penthiopyrad, 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 penthiopyrad and methoxy acrylate, which contains an active component A and an active component B, wherein the active component A is selected from penthiopyrad; the active component B is selected from any one of kresoxim-methyl, azoxystrobin, pyraclostrobin, fluoxastrobin, trifloxystrobin, orysastrobin, picoxystrobin and metominostrobin; and the weight ratio of the active component A to the active component B is 1:80-80:1. The composition has a synergistic action on multiple diseases jeopardizing agricultural production, reduces the pesticide consumption, lowers the residue level of the pesticide on crops, relieves the environmental pollution, is safe for both human and livestock and has favorable environmental compatibility, and the diseases can not easily generate drug resistance.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing penthiopyrad and methoxyacrylates 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 incomplete fungi, and is now recommended for the control of gray mold and powdery mildew that are resistant to other fungicides. [0003] Kresoxim-methyl, azoxystrobin, pyraclostrobin, fluoxastrobin, trifloxystrobin, oryzastrobin, picoxystrobin, and feno...
