Problems solved by technology

After research by the inventor, it was found that the compounding of cyclamenil, cyprodinil, pyrimethanil, methofencarb, iprodione, procymidone, and sclerotia had a good increase in a certain range. There are no relevant reports about the compounding of cyclazone, cyprodinil, pyrimethanil, diethofencarb, iprodione, procymidone, and sclerotin at home and abroad.

example 19～42

[0045] Example 19~42 water dispersible granules

[0046] Combine cyclohexasulfame, active ingredient B, dispersant, wetting agent, disintegrant, and filler together through airflow pulverization 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 fungicidal composition. The fungicidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is cyclohexyl flusulfamide, the active ingredient B is any compound selected from cyprodinil, pyrimethanil, diethofencarb, iprodione, procymidone and dimethachlon, and the weight ratio of the active ingredient A to the active ingredient B is (1: 70) to (70: 1). The composition disclosed by the invention has relatively high activity to various diseases of a variety of crops and has obvious synergism, and the fungicidal spectrum is enlarged; the composition has the characteristics of small dosage, rainwater washing resistance and obvious synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a bactericidal 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] In the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effects of pesticides are ad...
