Embodiment 1

[0031] Example 1 : 70% benzamid water dispersible granules.

[0032] Weigh 71% of the original powder of benzamid, 5% of the wetting agent octyl sulfosuccinate, 7% of the dispersant formaldehyde condensate of naphthalenesulfonate, 3% of the calcium lignosulfonate, and 3% of the disintegrating agent sodium sulfate 10%, binder sucrose 0.5%, defoamer isooctyl alcohol 0.4%, carrier diatomaceous earth to 100%; mix benzamid and other additives except binder in weightless Mix in the machine for 20 minutes, then put the mixture into the double-helix mixer (I), and pulverize it through the jet mill while mixing to reach a particle size of more than 1000 mesh, collect it through a cyclone separator and a bag filter, and finally put it in the double-helix mixer. Mix again for 30 minutes in the mixer (II) to obtain a uniform mother powder. Then accurately weigh the quantitative mother powder in the cyclone fluidized bed granulator, spray the binder aqueous solution according to the form...

Embodiment 2

[0033] Example 2 : 40% benzamid water dispersible granules.

[0034] Weigh 41% of benzamid original powder, 5% of wetting agent fatty alcohol polyoxyethylene ether, 5% of dispersant p-methoxy fatty amidobenzenesulfonic acid, 6% of sodium lignosulfonate, disintegrant sulfuric acid Sodium 20%, binder sucrose 0.5%, defoamer C8-10 fatty alcohol 1%, carrier light calcium carbonate to 100%, add benzamid and other additives except binder according to the formula The ratio is mixed in a gravity-free mixer for 20 minutes, and then the mixture is put into a double-screw mixer (I). While mixing, it is pulverized by a jet mill to reach a particle size of more than 1000 mesh, and is collected by a cyclone separator and a bag filter. , and finally mixed again for 30 minutes in the twin-screw mixer (II) to obtain a uniform mother powder. Then accurately weigh the quantitative mother powder in the cyclone fluidized bed granulator, spray the aqueous solution of the binder according to the f...

Embodiment 3

[0035] Example 3 : 30% benzamid water dispersible granules.

[0036] Weigh 30.8% of benzamid original powder, 5% of wetting agent fatty alcohol polyoxyethylene ether, 4% of dispersant p-methoxy fatty amidobenzenesulfonic acid, 6% of lignosulfonate calcium salt, disintegrant Sodium sulfate 30%, binder sucrose 0.5%, defoamer C8-10 fatty alcohol 1%, carrier diatomaceous earth to 100%, benzamid and other additives except binder according to the formula The ratio is mixed in a gravity-free mixer for 20 minutes, and then the mixture is put into a double-screw mixer (I). While mixing, it is pulverized by a jet mill to reach a particle size of more than 1000 mesh, and is collected by a cyclone separator and a bag filter. , and finally mixed again for 30 minutes in the twin-screw mixer (II) to obtain a uniform mother powder. Then accurately weigh the quantitative mother powder in the cyclone fluidized bed granulator, spray the binder aqueous solution according to the formula, and fi...

Abstract

The present invention relates to a zoxamide water dispersible granule and a preparation method thereof. The zoxamide water dispersible granule includes the components by weight: 10-80% of zoxamide, 1-8% of a wetting agent, 1-10% of a dispersing agent, 1-40% of a disintegrating agent, 0.3-5% of a defoaming agent, 0.5-4% of a binder and the balance a carrier. The preparation method includes: accurately weighing active ingredients, additives and the carrier according to a ratio, mixing, granulating after superfine grinding, finally analyzing, screening, and testing for storage. The zoxamide water dispersible granule helps to overcome the shortcomings of suspensions and wettable powders, has the advantages of both environmental protection and low using cost, and helps to reduce the pollution for environment in the processing and using processes and reduce the cost of farmers.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a water-dispersible granule of benzamid and a preparation method thereof. Background technique [0002] The mechanism of action of benzamid is unique among oomycete fungicides. It inhibits sclerotin fission through binding of tubulin β-subunits and disruption of the microtubule cytoskeleton. Benhexamid did not affect zoospore motility, cyst formation or germination. Along with the first cycle of sclerotia fission, germ tube elongation is inhibited, thereby preventing the pathogen from penetrating the host plant. It is mainly used to control oomycete diseases such as potato and tomato late blight, cucumber downy mildew and grape downy mildew, etc.; it has special effects on grape downy mildew. The in vitro test shows that benzamid also has certain activity against other fungal pathogens, and it is speculated that it has certain activity against sweet potato gray mold, lett...
