Embodiment 1

[0031] Example 1: 80% water-dispersible granules of cyclomethoxyfen.

[0032] Weigh 80% of cyclic ester fluoride, 4% of wetting agent sodium lauryl sulfate, 3% of dispersant polycarboxylate 2700, 4% of sodium lignosulfonate, 5% of disintegrating agent sodium sulfate, defoamer Isooctyl alcohol 0.4%, binder sucrose 0.5%, carrier kaolin supplemented to 100%; cyclomethicone and other additives except binder were mixed in a gravity-free mixer for 20 minutes according to the formula ratio, and then The mixture is put into the twin-screw mixer (Ⅰ), crushed by the airflow mill while mixing to reach a particle size of more than 1000 mesh, collected by the cyclone separator and bag filter, and finally mixed again in the double-screw mixer (II) 30 minutes to get 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 wat...

Embodiment 2

[0034] Example 2: 50% water-dispersible granules of cyclomethoxyfen.

[0035] Weigh 50% of cyclic ester fluoride, 4% of wetting agent sodium lauryl sulfate, 3% of dispersant naphthalenesulfonate formaldehyde condensate, 4% of sodium lignosulfonate, 30% of disintegrating agent urea, and 0.5% sucrose as agent, 0.3% organosilicone as antifoaming agent, and diatomaceous earth as carrier to 100%, mix fenclofen and other additives except binder in a gravity-free mixer for 20 minutes according to the formula ratio , and then put the mixture into the twin-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 the cyclone separator and bag filter, and finally put it in the double-helix mixer (II) 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 for...

Embodiment 3

[0037] Example 3: 20% water-dispersible granules of cyclomethoxyfen.

[0038] Weigh 20% of cyclamate, 7% of sodium octyl sulfosuccinate as a wetting agent, 5% of sodium fatty alcohol polyoxyethylene ether sulfate as a dispersant, 4% of sodium lignosulfonate, 20% of urea as a disintegrating agent, Binder 0.5% sucrose, defoamer C8-10 fatty alcohol 0.8%, carrier attapulgite to 100%, cyclomethopoxyfen and other additives except the binder according to the formula ratio in the gravity-free mixing Mix in the machine for 20 minutes, then put the mixture into the double-helix mixer (I), and pulverize it through the jet 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-helix mixer. Mix again for 30 minutes in the mixer (II) to obtain a uniform mother powder. Then accurately weigh the quantitative mother powder in the cyclone fluidized bed granulator, spray the binder aqueous solu...

Abstract

The invention relates to a pyriftalid water dispersible granule and a preparation method thereof. The pyriftalid water dispersible granule is prepared from the following components in percentage by weight: 10-80% of pyriftalid, 1-8% of a wetting agent, 1-10% of a dispersing agent, 1-40% of a disintegrating agent, 0.3-5% of a defoamer, 0.5-4% of an adhesion agent, and the balance is a carrier; the preparation method comprises the following steps: uniformly mixing the raw materials except the adhesion agent; adding the mixture after ultrafine grinding to a water solution of the adhesion agent so as to carry out granulation; and finally, drying, screening, analyzing, testing, and putting in a storage. The pyriftalid water dispersible granule provided by the invention has the advantages of overcoming defects of a suspending agent and wettable powder, and having environmental friendliness and low use cost; and in processing and use processes, environmental pollution use cost of farmers are reduced.

Description

technical field [0001] The invention relates to an agricultural herbicide and a preparation method thereof, in particular to a water-dispersible granule of cyclamate and a preparation method thereof. Background technique [0002] Cyclofenac is an early post-emergence broad-spectrum herbicide for rice, specially developed for transplanting and direct-seeding rice. Its mechanism of action is to inhibit the synthesis of acetolactate synthase (ALS). It is used to control gramineous weeds and some broad-leaved weeds in paddy fields. In paddy fields, pentaclofen is absorbed by the root tips of rice, and a small part will be transmitted to the leaves, and a small part of the pesticide will be absorbed by the budding weed leaves. absorbed. The results of indoor active biological test and field efficacy test show that it has a good control effect on annual grass weeds and some broad-leaved weeds of Cyperaceae in transplanted rice fields. It has a good control effect on barnyardgra...
