Problems solved by technology

These water-dispersible granules only contain four additives: dispersant, wetting agent, disintegrant, and filler. The formulation has the disadvantages of poor product shape during granulation, and low suspension rate when used in high-concentration hard water areas.
And the water dispersible granule of single propanil drug active ingredient and its preparation method have not been reported at present

Embodiment 1

[0028] Embodiment 1 80% propanil water dispersible granules

[0029] Propannil 80%, dispersant polycarboxylate sodium salt 2.5%, maleic acid-acrylic acid copolymer 2.5%, wetting agent dodecylbenzenesulfonate 1.33%, naphthalenesulfonic acid formaldehyde condensate sodium salt 0.67%, Disintegrant ammonium sulfate 5%, binder polyvinylpyrrolidone 1.0%, chelating agent disodium edetate 0.75%, sodium tripolyphosphate 0.75%, cornstarch supplement 100%. After the mixture is fully mixed and uniform, carry out ultrafine airflow pulverization to obtain a 750-mesh fine powder, and then add an appropriate amount of water to the kneader to knead the resulting fine powder, and then granulate it through an extrusion granulator. Dry at ℃ to get 80% propanil water dispersible granules.

Embodiment 2

[0030] Embodiment 2 60% propanil water dispersible granules

[0031] Propaniln 60%, dispersant polycarboxylate sodium salt 2.5%, maleic acid-acrylic acid copolymer 2.5%, wetting agent dodecylbenzenesulfonate 1.33%, naphthalenesulfonic acid formaldehyde condensate sodium salt 0.67%, Disintegrant ammonium sulfate 5%, binder polyvinylpyrrolidone 1.0%, chelating agent disodium edetate 0.75%, sodium tripolyphosphate 0.75%, cornstarch supplement 100%. After the mixture is fully mixed and uniform, carry out ultrafine airflow pulverization to obtain a 700-mesh fine powder, and then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and 50 Dry at ℃ to get 60% propanil water dispersible granules.

Embodiment 3

[0032] Embodiment 3 50% propanil water dispersible granules

[0033] Propaniln 50%, dispersant polycarboxylate sodium salt 2.5%, maleic acid-acrylic acid copolymer 2.5%, wetting agent dodecylbenzenesulfonate 1.33%, naphthalenesulfonic acid formaldehyde condensate sodium salt 0.67%, Disintegrant ammonium sulfate 5%, binder polyvinylpyrrolidone 1.0%, chelating agent disodium edetate 0.75%, sodium tripolyphosphate 0.75%, cornstarch supplement 100%. After the mixture is fully mixed and uniform, carry out ultrafine airflow pulverization to obtain a 780-mesh fine powder, and then add an appropriate amount of water to the kneader to knead the resulting fine powder, and then granulate it through an extrusion granulator. Dry at ℃ to get 50% propanil water dispersible granules.

Abstract

The invention discloses propanil water dispersible granules. The propanil water dispersible granules comprise the following ingredients in percentage by weight: 10-80% of propanil, 1-10% of a dispersing agent, 1-12% of a wetting agent, 1-25% of a disintegrating agent, 1-10% of an adhesive, 1-5% of a chelating agent and the balance being a carrier. The propanil water dispersible granules disclosed by the invention are simple in preparation technology, low in cost, safe, environmentally-friendly, free of dust pollution, difficult to cause pesticide hazard, convenient to use and suitable for large-scale popularization and application, adapts to high-concentration wastewater and has the good shaping property and excellent prevention effect on grass families in paddy fields and dicotyledonous weeds such as barnyard grass, monochoria vaginalis, water fennels, crab grasses and green bristlegrass.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a propanil water-dispersible granule and a preparation method thereof. Background technique [0002] Pesticide water dispersible granules are water-insoluble solid pesticide raw materials, wetting agents, dispersants, other functional additives and carriers, which are thoroughly mixed and pulverized into fine powder solids, and then kneaded, granulated, dried and sieved The pesticide formulation formed by the grading operation can be rapidly disintegrated into the original particle size in water and dispersed into a stable suspension. Water-dispersible granules have no solvent and dust, are safe for operators, have no airiness, avoid the disadvantages of traditional dosage forms such as emulsifiable concentrate, powder and wettable powder, such as large amount of solvent and dust, absorb and utilize its advantages, and develop rapidly. It is considered ...
