Embodiment 1

[0032] Example 1: 80% cyprodinil water-dispersible granules.

[0033] Take by weighing 81% of the former powder of cyprodinil, 4% of wetting agent sodium lauryl sulfate, 3% of dispersant polycarboxylate 2700, 4% of sodium lignosulfonate, 5% of disintegrating agent sodium sulfate, and Foaming agent isooctyl alcohol 0.4%, binder sucrose 0.5%, carrier kaolin to 100%; mix cyprodinil and other additives except binder in a gravity-free mixer according to the formula ratio for 20 minutes, Then put the mixture into the twin-screw mixer (I), and grind it through the jet mill while mixing to reach a particle size of more than 1000 mesh, collect it through the cyclone separator and bag filter, and finally put it in the double-helix mixer (II). Mix again for 30 minutes to obtain a homogeneous 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 finally dry to obtain...

Embodiment 2

[0034] Example 2: 70% cyprodinil water-dispersible granules.

[0035] Weigh 71% of the original powder of cyprodinil, wetting agent sulfosuccinate sodium salt 5%, dispersant naphthalenesulfonate formaldehyde condensate 7%, lignosulfonate calcium salt 3%, disintegrant sodium sulfate 10%, binder sucrose 0.5%, defoamer isooctyl alcohol 0.4%, carrier kaolin to 100%; put cyprodinil and other additives except binder in a gravity-free mixer according to the formula ratio Mix for 20 minutes, then put the mixture into the double-screw 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-screw mixer (II) and mix again for 30 minutes 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 finally dry t...

Embodiment 3

[0036] Example 3: 50% cyprodinil water-dispersible granules.

[0037] Weigh 52% of the original powder of cyprodinil, 4% of wetting agent sodium lauryl sulfate, 3% of dispersant naphthalenesulfonate formaldehyde condensate, 4% of sodium lignosulfonate, 30% of disintegrating agent urea, Binder sucrose 0.5%, defoamer organic silicone 0.3%, carrier diatomaceous earth to 100%, mix cyprodinil and other additives except binder in a gravity-free mixer according to the formula ratio After 20 minutes, put the mixture into the double-screw mixer (I), and pulverize it through the airflow 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-screw mixer ( Ⅱ) and mix again for 30 minutes 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 finall...

Abstract

The invention discloses a cyprodinil water dispersible granule and a preparation method thereof; the granule comprises the following components by weight: 10-80% of cyprodinil, 1-8% of a wetting agent, 1-10% of a dispersant, 1-40% of a disintegrating agent, 0.5-4% of a binder, 0.3-5% of an antifoaming agent, and the balance of carriers. The invention also discloses the preparation method of the cyprodinil water dispersible granule. The invention overcomes the disadvantages of suspending agents and wettable powder, and combines the advantages of both environmental protection and low application cost; during processing and application, environment pollution is reduced, and the application cost for peasants is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a cyprodinil water-dispersible granule and a preparation method thereof. Background technique [0002] Cyprodinil mainly inhibits the biosynthesis of methionine and inhibits the secretion of hydrolase. Absorbed quickly by leaves in plants, more than 30% penetrates into tissues, the protected sediment is stored in leaves, transported in xylem, and also transported between leaves, metabolism is relatively rapid at high temperature, and in leaves at low temperature The precipitate in is fairly stable and the metabolites are biologically inactive. It is used to control Botrytis cinerea, powdery mildew, scab, blight and wheat eye streak disease. [0003] The use of traditional pesticides, mainly emulsifiable concentrates and powders, played an irreplaceable role in preventing and controlling pests and weeds, capturing agricultural harvests, and ensuring people's lives when the ...
