Embodiment 1

[0031] Example 1: 20% clodinafop-propargyl water-dispersible granules.

[0032] Weigh clodinafop-propargyl technical 20%, wetting agent sodium lauryl sulfate 4%, dispersant polycarboxylate 3%, sodium lignosulfonate 4%, disintegrant sodium sulfate 5%, appropriate amount of filler kaolin After mixing it evenly, it is pulverized by an airflow mill to obtain the mother powder. After mixing the mother powder with the binder carboxymethyl cellulose 0.5% and water evenly, it is then granulated, dried, and sieved to obtain 20% alkyne Water dispersible granule of grass ester.

[0033] This example is used to prevent and control gramineous weeds in winter wheat fields, the dosage of active ingredients is 45-60 g / hectare, and the control effect is 85%-97%.

Embodiment 2

[0034] Example 2: 80% clodinafop-propargyl water-dispersible granules.

[0035] Take clodinafop-propargyl former medicine 80%, wetting agent fatty alcohol polyoxyethylene ether 3%, dispersant polycarboxylate 4%, lignin 4%, disintegrant urea 5%, appropriate filler white carbon black, will After it is mixed evenly, it is pulverized by an airflow mill to obtain the mother powder. After the mother powder is mixed with the binder polyethylene glycol 0.5% and water evenly, it is then granulated, dried, and sieved to obtain 80% clodinafop-propargyl water. Dispersible granules.

[0036] This embodiment is used to prevent and control gramineous weeds in spring wheat fields, the dosage of active ingredients is 45-60 g / ha, and the control effect is 90%-95%.

Abstract

The invention relates to a clodinafop-propargyl water dispersible granule and a preparation method thereof. The clodinafop-propargyl water dispersible granule comprises the following components in percentage by weight: 5-85% of clodinafop-propargyl, 1-8% of wetting agent, 1-10% of dispersing agent, 1-10% of disintegrating agent, 0.5-4% of binding agent and the balance of packing material. The preparation method comprises the following steps of: uniformly mixing the above raw materials except for the binding agent; then, ultrafine grinding the mixture, and adding the powder into the water solution of binding agent to granulate; and finally drying, screening, analyzing, inspecting and warehousing the granule. The clodinafop-propargyl water dispersible granule overcomes the defects of suspension and wettable powder and combines the advantages of environmental protection and low use cost. The pollution to the environment is lowered during the processing and use process, and the use cost of peasants is lowered.

Description

technical field [0001] The invention relates to an agricultural herbicide and a preparation method thereof, in particular to a clodinafop-propargyl water-dispersible granule and a preparation method thereof. Background technique [0002] Clodinafop-propargyl, an aryloxyphenoxypropionic acid herbicide, can effectively inhibit the biosynthesis of esters and become an acetyl cosensitizer A hydroxylase inhibitor. It can control grass weeds such as wheat voles, oat grass, ryegrass, common bluegrass foxtail and so on. [0003] At present, clodinafop-propargyl is generally made into wettable powder in use. Although wettable powder has low production cost, it is not environmentally friendly, and the dust drift is relatively serious, which brings inconvenience to production, transportation and use. [0004] Water-dispersible granules are a new type of dosage form. In recent years, research institutes and enterprises at home and abroad have paid more attention to the research of thi...
