example 17～32
[0045] Example 17~32 water dispersible granules
[0046] Combine cyclohexasulfame, active ingredient B, dispersant, wetting agent, disintegrant, and filler together through airflow crushing to obtain the required particle size, and then add binder (optional) and other additives to obtain the preparation grain materials. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying.

Abstract
The invention discloses a pesticide composition. The pesticide composition contains an active component A and an active component B, wherein the active component A is N-(2-trifluoromethyl-4-chlorphenyl)-a-oxocyclohexyl sulfonamide, the active component B is any one compound selected from the group consisting of pyraclostrobin, fluoxastrobin, metominostrobin, enestroburin, coumoxystrobin and orysastrobin, and a weight ratio of the active component A to the active component B is 1: 60 to 80: 1. The pesticide composition has high activity on a plurality of diseases of a plurality of crops, a substantial synergistic effect, a broadened bactericidal spectrum and the characteristics of a small usage amount, resistance to rain wash and substantial synergy.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition on crop diseases. technical background [0002] Cyclohexasulfame chemical name: N-(2-trifluoromethyl-4-chlorophenyl)-a-oxocyclohexylsulfonamide. It has strong preventive, therapeutic and osmotic activities, and has high persistence. The field test results show that cyclazone can effectively control Botrytis cinerea, rape sclerotinia, cucumber brown spot and scab. [0003] Pyraclostrobin, fluoxastrobin, phenoxystrobin, erythoxystrobin, syringstrobin, and oryzastrobin are all methoxyacrylate fungicides, methoxyacrylate fungicides It is an external quinone inhibitor, which inhibits mitochondrial respiration by hindering the electron transfer between cytochrome b and cytochrome c1. The selectivity comes from the deesterification of enzymes in plants. It has protective, therapeutic, eradicating and long-lasting effects, and inhibits spor...
