Embodiment 1～18

[0053] The specific processing steps of the wettable powder of the bactericidal composition are as follows: mix the active ingredient A, the active ingredient B, the dispersant, the wetting agent, and the filler according to the formula, mix evenly in a mixing tank, and then mix evenly after being pulverized by a jet mill, that is, The wettable powder of the present invention can be made.

[0054]

[0055] Water-dispersible granules (formulation examples 19-36)

[0056] The specific processing steps of the water-dispersible granules of the fungicidal composition are as follows: according to the formula, the active ingredient A, the active ingredient B, the dispersant, the wetting agent, the disintegrating agent, and the filler are uniformly mixed, pulverized with an ultrafine jet mill, and kneaded. Then put it into a fluidized bed granulation dryer for granulation, drying and sieving, and then the water-dispersible granules of the present invention can be prepared.

[0087] Toxicity Determination Example 1 Indoor Toxicity Determination Test of Indazolesulprofesmin and Fluopyram to Grape Downy Mildew

[0088] Test object: grape downy mildew ( Plasmopara uiticola (Berk. dt Curtis) Berl. Et de Tony )

[0089] Test method: refer to the standard method of bioassay NY / T 1156.3-2006, and use the flat plate leaf method.

[0090]

[0091] It can be seen from Table 12 that when the ratio of indazolesulfame and fluopicolide is between 1:80 and 80:1, the co-toxicity coefficients are all above 120, which has a synergistic effect on grape downy mildew, especially in Between 1:40 and 30:1, the co-toxicity coefficient is above 160.

[0092] Toxicity Determination Example 2 Indoor Toxicity Determination Test of Indazolesulfin and Boscalid on Potato Late Blight

[0093] Test object: Potato infestans ( Phytophthora infestans (Mont.) de Bary )

[0094] Test method: refer to the standard method of bioassay NY / T 1156.13-2008, and adopt the leaf method.

[0095]

[0096] It can be seen from Table 13 that when the ratio of indazolesulfame and boscalid is between 1:80 and 80:1, the co-toxicity coefficients are all above 120, which has a synergistic effect on potato late blight, especially at 1 :20~40:1, the co-toxicity coefficient is above 160.

Abstract

The invention discloses a high-efficiency bactericidal composition. The composition comprises an active ingredient A amisulbrom and an active ingredient B, wherein the active ingredient B is selected from any one of the following compounds: fluopicolide, boscalid, fluoxastrobin, azoxystrobin, kresoxim-methyl, metalaxyl, prothioconazole, Bordeaux mixture and basic copper sulfate; the weight ratio of the active ingredient A to the active ingredient B is (1 to 80)-(80 to 1). The bactericidal composition has obvious synergetic effects, can be used for controlling diseases on vegetables, fruit trees and tobaccos, can achieve the effect of reducing the usage amount of pesticides, the amount of residues of pesticides on crops and environmental pollution, is safe to people and livestock, has good environmental compatibility and enables the diseases not to easily have pesticide resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a high-efficiency bactericidal composition containing indazole sulfastrobin and its application on crop diseases. Background technique [0002] Amisulbrom: It is a triazole sulfonamide fungicide developed by Nissan Chemical in the 1990s. The chemical name is 3-(3-bromo-6-fluoro-2-methylindole-1-sulfonyl)-N,N-dimethyl-1,2,4-triazole-1-sulfonamide, molecular formula for C 13 h 13 BrFN 5 o 4 S 2 . The fungicide has high activity against plant diseases caused by oomycetes, does not have systemic properties, and is mainly for prevention. [0003] Fluopicolide: It is a fungicide developed by Bayer Crop Science Company in Germany. The drug has good protection and strong permeability. It has high biological activity against oomycete fungal diseases and has good control The effect can be transmitted from the base of the plant to the tip of the leaf. Chemical name: 2,6-dichloro-N...
