Embodiment 1

[0031] Example 1: 80% indoxacarb water dispersible granules.

[0032] Weigh in proportion (by weight) 80% of indoxacarb, 2% of wetting agent alkyl butanedisulfonate, 4% of dispersant of alkylphenol polyoxyethylene ether formaldehyde condensate carboxylate, alkyl naphthalene Formaldehyde condensate iodate 3%, disintegrant sodium sulfate 4%, binder polyethylene glycol 1%, defoamer isooctyl alcohol 0.5%, penetrant silicone 0.5%, filler kaolin to 100%; Mix indoxacarb and the rest of the additives except the binder in a gravity-free mixer according to the formula ratio for 20 minutes, then put the mixture into the double-screw mixer (I), and pulverize it through the jet mill while mixing When the particle size reaches more than 1000 mesh, it is collected by a cyclone separator and a bag filter, and finally mixed again in a double-screw mixer (II) for 30 minutes to obtain a uniform mother powder. Then accurately weigh the quantitative mother powder in the cyclone fluidized bed ...

Embodiment 2

[0033] Example 2: 50% indoxacarb water dispersible granules.

[0034] Weigh (by weight) indoxacarb 50%, wetting agent sodium lauryl sulfate 4%, dispersant polycarboxylate 3%, sodium lignosulfonate 4%, disintegrant urea 25% , binder sucrose 0.5%, defoamer organic silicone 0.3%, filler diatomaceous earth to 100%, mix indoxacarb 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 finally dry to obtain irregular granular water-dispersible granules, and ...

Embodiment 3

[0035] Example 3: 20% indoxacarb water dispersible granules

[0036] Weigh in proportion (by weight) 20% of indoxacarb, 2% of wetting agent sodium lauryl sulfate, 5% of dispersant alkylphenol polyoxyethylene ether formaldehyde condensate, 30% of disintegrating agent urea, and Polyethylene glycol 5% as agent, 0.3% organosilicone as defoaming agent, diatomaceous earth as filler to 100%, mix indoxacarb 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, an...

Abstract

The invention discloses an indoxacarb water dispersible granule and a preparation method thereof. The indoxacarb water dispersible granule consists of indoxacarb, a wetter, a dispersant, a disintegrant, a binder, a defoamer, a penetrant and a filler. According to the invention, as the indoxacarb is subject to ultramicro crushing and then pelletized to obtain the water dispersible granule, the shortcomings of traditional medicament forms, such as missible oil and wettable powder, are overcome, the advantages of environmental protection and low use cost are achieved, and during processing and use, environmental pollution is reduced and the use cost is lowered for peasants.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an indoxacarb water-dispersible granule and a preparation method thereof. Background technique [0002] Indoxacarb has contact and stomach poisoning effects, and can effectively control various pests on crops such as grain, cotton, fruit, and vegetables, and is effective against larvae of all ages. The insecticide enters the insect body through contact and feeding. The insect stops feeding within 0-4 hours and is paralyzed. There is no cross-resistance to other insecticides. Indoxacarb has low toxicity to mammals and livestock, and is very safe to beneficial insects such as non-target organisms in the environment. It has low residue in crops and can be harvested on the second day after application. It is suitable for crops that have been harvested many times. For example, vegetables are also very suitable, and can be used for integrated pest control and resistance manageme...
