Example Embodiment

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

[0032] Weigh (by weight) 80% indoxacarb, 2% wetting agent alkyl succinate, dispersant 4% alkylphenol polyoxyethylene 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 make up to 100%; Mix indoxacarb and other additives except the binder in a non-gravity mixer for 20 minutes according to the formula ratio, and then put the mixture into a double screw mixer (Ⅰ), and pulverize by a jet mill while mixing When the particle size is above 1000 meshes, it is collected by a cyclone separator and a bag filter, and finally mixed in a double screw mixer (II) for another 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 ...

Example Embodiment

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

[0034] Weigh (by weight) indoxacarb 50%, wetting agent sodium lauryl sulfate 4%, dispersing agent polycarboxylate 3%, lignosulfonate 4%, disintegrating agent urea 25% , Binder sucrose 0.5%, defoamer organosilicone 0.3%, filler diatomaceous earth to make up to 100%, mix indoxacarb and other additives except binder in a non-gravity mixer according to the formula ratio After 20 minutes, put the mixture into the double screw mixer (I), mix and pulverize by the jet mill to reach a particle size of more than 1000 meshes, collect it by a cyclone separator and a bag filter, and finally in the double screw mixer ( Ⅱ) Mix again for 30 minutes to obtain a uniform master powder. Then accurately weigh a certain amount of mother powder in a rotary fluidized bed granulator, spray the binder aqueous solution according to the formula, and finally dry it to obtain irregular granular water-dispersible granules, and then screen to obtai...

Example Embodiment

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

[0036] Weigh (by weight) indoxacarb 20%, wetting agent sodium lauryl sulfate 2%, dispersing agent alkylphenol polyoxyethylene ether formaldehyde condensate 5%, disintegrating agent urea 30%, bonding Polyethylene glycol 5%, antifoaming agent 0.3% silicone, filling diatomaceous earth to make up to 100%, mix indoxacarb and other additives except the binder in a non-gravity mixer according to the formula ratio After 20 minutes, put the mixture into the double screw mixer (I), mix and pulverize by the jet mill to reach a particle size of more than 1000 meshes, collect it by a cyclone separator and a bag filter, and finally in the double screw mixer ( Ⅱ) Mix again for 30 minutes to obtain a uniform master powder.

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...
