Embodiment 1

[0032] Example 1: 80% flonicamid water dispersible granule.

[0033] Take by weighing 80% of the original drug of flonicamid, 4% of wetting agent sodium lauryl sulfate, 3% of dispersant polycarboxylate 2700, 4% of lignosulfonate, 5% of disintegrating agent sodium sulfate, Foaming agent isooctyl alcohol 0.4%, binder glucose 0.5%, carrier kaolin to 100%; flonicamid and other additives except the binder were mixed in a gravity-free mixer for 20 minutes according to the formula ratio, 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 irre...

Embodiment 2

[0034] Example 2: 50% flonicamid water dispersible granules.

[0035] Weigh 50% of the original drug of flonicamid, 4% of sodium lauryl sulfate as a wetting agent, 3% of naphthalenesulfonate formaldehyde condensate as a dispersant, 4% of lignosulfonate, 30% of urea as a disintegrating agent, Binder polyvinyl alcohol 0.5%, defoamer organosilicone 0.3%, carrier diatomaceous earth to 100%, flonicamid and other additives except the binder in a gravity-free mixer according to the formula ratio Mix in the middle for 20 minutes, then put the mixture into the double-helix mixer (I), 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 mix it in a double-helix mixer Mix again in machine (II) 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 acco...

Embodiment 3

[0036] Example 3: 30% flonicamid water dispersible granules.

[0037] Weigh 30% of flonicamid raw powder, 5% of wetting agent fatty alcohol polyoxyethylene ether, 4% of dispersant p-methoxy fatty amidobenzenesulfonic acid, 6% of lignosulfonate, disintegrant sulfuric acid Sodium 30%, binder gelatin 0.5%, defoamer C8-10 fatty alcohol 1%, carrier diatomaceous earth to 100%, flonicamid and other additives except binder according to the formula ratio Mix in a gravity-free mixer for 20 minutes, then put the mixture into a double-screw mixer (I), and pulverize it through an airflow mill while mixing to reach a particle size of more than 1000 mesh, and collect it through a cyclone separator and a bag filter. Finally, mix again in the twin-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, spray the binder aqueous solution according to the formula, and finally dry to obtain ir...

Abstract

The invention discloses a flonicamid water dispersible granule and a method for preparing the flonicamid water dispersible granule. The flonicamid water dispersible granule comprises the following components in percent by weight: 10-80% of flonicamid, 1-8% of wetting agent, 1-10% of dispersing agent, 1-40% of disintegrating agnet, 0.5-4% of binding agent, 0.3-5% of defoaming agent and the balance of carrier. The flonicamid water dispersible granule overcomes the defects of the wettable powder and other traditional preparations, has the advantages of environment friendliness and low use cost and causes less pollution to the environment when being processed and used. Due to the adoption of the flonicamid water dispersible granule, the use cost of the peasants is reduced.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a water-dispersible granule of flonicamid and a preparation method thereof. Background technique [0002] Flunicamid is effective against various piercing-sucking mouthparts pests and has good penetration. It can penetrate from roots to stems and leaves, but the penetration from leaves to stems and roots is relatively weak. The drug works by hindering the sucking action of the pests, and the pests stop sucking soon after ingesting the drug, and finally starve to death. Due to the unique mechanism of action and high biological activity of flonicamid, as well as its high safety to humans, animals and the environment, and its effectiveness against other insecticide-resistant pests, it has great room for development . [0003] The use of traditional pesticides, mainly emulsifiable concentrates and powders, has the disadvantages of environmental pollution,...
