Embodiment 1

[0031] Example 1: 80% trifloxystrobin water-dispersible granule.

[0032] Weigh in proportion (by weight) 80% trifloxystrobin, wetting agent alkyl butanedisulfonate 2%, dispersant alkylphenol polyoxyethylene ether formaldehyde condensate carboxylate 4%, 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 trifloxystrobin and other additives except the binder in a gravity-free mixer for 20 minutes according to the formula ratio, then put the mixture into a double-screw mixer (I), and pulverize it by an airflow 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 granulator, ...

Embodiment 2

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

[0034] Weigh (by weight) trifloxystrobin 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%, trifloxystrobin and other additives except binder are mixed 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-dispe...

Embodiment 3

[0035] Example 3: 20% trifloxystrobin water-dispersible granule.

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

Abstract

The invention discloses a trifloxystrobin water dispersible granule and a preparation method thereof. The trifloxystrobin water dispersible granule consists of trifloxystrobin, a wetter, a dispersant, a disintegrant, a binder, a defoamer, a penetrant and a filler. According to the invention, as the trifloxystrobin 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 specifically relates to a trifloxystrobin water-dispersible granule and a preparation method thereof. Background technique [0002] Trifloxystrobin is a mitochondrial respiration inhibitor that prevents electron transfer in the synthesis of cytochrome bcl, and has protective, therapeutic, and leaf osmotic conduction effects. The field efficacy test results show that trifloxystrobin has good control effect on cucumber powdery mildew, downy mildew, banana scab and leaf spot. Spraying starts at the early stage of the disease, generally spraying 3 times with an interval of 10 days. The second-grade medicine is safe for cucumbers and bananas, and no harm has been reported. [0003] At present, trifloxystrobin is mainly based on emulsifiable concentrate. Since emulsifiable concentrate preparations are mainly formulated with aromatic organic solvents, a large amount of aromatic organic solvents such as to...
