Embodiment 1

[0018] Mix 5% of refined metolachlor with 1% of alkylphenol polyoxyethylene ether phosphate, 5% of polyoxyethylene polyoxypropylene ether block copolymer, and 3% of phenylphenol polyoxyethylene ether , 5% methylated palm oil, mixed evenly, adsorbed with 20% white carbon black to form a flowable powder, and then mixed with 0.5% pyrazosulfuron methyl, 2% sodium lignosulfonate, 5% polycarboxylate Salt dispersant, 10% corn starch and glass floating beads make up 100%, mix evenly, and then pulverize by jet mill to obtain mother powder. Then the obtained mother powder is moistened with an appropriate amount of water, kneaded evenly with a kneader, and then extruded and granulated with an extrusion granulator to obtain wet granules containing refined metolachlor and pyrazosulfuron-methyl as active ingredients. After the wet granules were dried, the qualified 5.5% refined isopropyl-pyrazine floating granules for paddy field weeding were obtained.

Embodiment 2

[0020] Mix 10% of refined metolachlor with 2% of alkylphenol polyoxyethylene ether phosphate, 6% of polyoxyethylene polyoxypropylene ether block copolymer, 4% of phenylphenol polyoxyethylene ether , 8% methylated palm oil, mixed evenly, adsorbed with 22% white carbon black to form a flowable powder, and then mixed with 1.0% pyrazosulfuron methyl, 3% sodium lignosulfonate, 6% polycarboxylate Salt dispersant, 8% corn starch and glass floating beads make up 100%, mix evenly, and then pulverize by jet mill to obtain mother powder. Then the obtained mother powder is moistened with an appropriate amount of water, kneaded evenly with a kneader, and then extruded and granulated with an extrusion granulator to obtain wet granules containing refined metolachlor and pyrazosulfuron-methyl as active ingredients. The wet granules were dried to obtain qualified 11% refined isopropyl-pyrazine paddy field weeding floating granules.

Embodiment 3

[0022] Mix 15% of refined metolachlor with 3% of alkylphenol polyoxyethylene ether phosphate, 6% of polyoxyethylene polyoxypropylene ether block copolymer, 4% of phenylphenol polyoxyethylene ether , 10% methylated palm oil, mixed evenly, adsorbed with 25% white carbon black to form a flowable powder, and then mixed with 1.5% pyrazosulfuron methyl, 4% sodium lignosulfonate, 6% polycarboxylate Salt dispersant, 10% corn starch and glass floating beads make up 100%, mix evenly, and then pulverize by jet mill to obtain mother powder. Then the obtained mother powder is moistened with an appropriate amount of water, kneaded evenly with a kneader, and then extruded and granulated with an extrusion granulator to obtain wet granules containing refined metolachlor and pyrazosulfuron-methyl as active ingredients. After drying the wet granules, a qualified 16.5% refined isopropyl-pyrazine floating granule for paddy field weeding was obtained.

Abstract

The invention relates to a paddy field weeding floating granule and a preparation method thereof. The floating granule comprises 1-15 wt% of original S-metolachlor, 0.5-4 wt% of pyrazosulfuron-ethyl,1-20 wt% of a surfactant, 1-25 wt% of an adsorbent, 1-20 wt% of an of oily substance, 1-10 wt% of corn starch and 15-50 wt% of a solid core material. The above formula of the above preparation contains a diffusing agent and other surfactants, so the granule can float on the water level after being applied, can float and diffuse under the action of the contained surfactant and natural wind, diffuses to the water level of all the field in a short time, and then settles to soil from the water level. The floating granule has the characteristics of simple production process, convenience in storageand transportation, time-saving and labor-saving application, and realization of long-lasting effect after application.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a paddy field weeding floating granule and a preparation method thereof. Background technique [0002] With the improvement of the precision of the target of pesticide application and the increasing emphasis on environmental protection, some dosage forms that pollute the environment are gradually eliminated and replaced by new dosage forms with high efficiency, low toxicity and environmental protection, which are gradually promoted and applied. . In recent years, the research on labor-saving technology of paddy field weeding has gradually been extensive and in-depth. The floating granules for paddy field weeding have simple processing technology, safe and convenient storage and transportation, time-saving and labor-saving application, and stable and long-lasting efficacy. It has obvious practical value and development prospect. The action point of the mixture of...
