Embodiment 1

[0040] Formulation Example 1: 23.4% furansulcotrione · oxaziclomefone · thiamid aqueous suspension concentrate

[0041] Furosulcotrione 7.5%, Oxazicone 0.9%, Dithiazide 15%, Polyoxyethylene polyoxypropylene ether block copolymer 10%, Sodium butylnaphthalene sulfonate 6%, Xanthan gum 2 %, C 10-20Saturated fatty acid compound 0.1%, urea 3%, deionized water supplemented to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a 23.4% furansulcotrione·oxaziclodione·thiamid aqueous suspension concentrate.

Embodiment 2

[0042] Formulation Example 2: 26.2% furansulcotrione · oxaziclomefone · dithiamid dispersible oil suspension concentrate

[0043] Furosulcotrione 5%, Oxazimidone 1.2%, Mefenacet 20%, Fatty Alcohol Polyoxyethylene Ether 5%, Castor Oil Polyoxyethylene Ether 15%, Xanthan Gum 2%, White Carbon Black 3 %, cyclohexanone 5%, and palm oil to make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 26.2% furasulcotrione·oxaziclodione·fenthiamid dispersible oil suspension concentrate.

Embodiment 3

[0044] Formulation example 3: 69.3% furansulcotrione · oxaziclomefone · dithiamid water dispersible granules

[0045] Furansulotrione 7.5%, Oxazicone 1.8%, Mefenacet 60%, Polycarboxylate 6%, Sodium Dodecyl Benzene Sulfonate 4%, Low-substituted Hydroxypropyl Cellulose 5%, Kaolin tops up to 100%. The above-mentioned materials are mixed in proportion, air-jet pulverized, mixed evenly, kneaded and granulated, dried and sieved to obtain 69.3% furansulcozone·oxaziclodione·thiamid water-dispersible granule.

Abstract

The invention discloses a weeding composition containing tefuryltrione, oxaziclomefone and mefenacet. The effective components consist of the tefuryltrione, the oxaziclomefone and the mefenacet; the weight ratio of the tefuryltrione to the oxaziclomefone to the mefenacet in the composition is (0.5 to 50) to 6 to (20 to 200); the weight sum of the tefuryltrione, the oxaziclomefone and the mefenacetin the composition is 0.1% to 85%. The weeding composition has the advantages that in the actual application process, the weeding composition can be processed into the application preparations of water suspension agents, dispersible oil suspension agents, emulsion oil, water dispersion granule and granule, and be used for preventing and removing the weeds in a rice field; compared with the singleuse of each single agent or mutually binary compounding of the single agent, the weeding composition of the invention has the advantages that the weeding effect is obviously improved, the weeding spectrum is broadened, the lasting period is long, and the safety effect is realized for rice.

Description

technical field [0001] The present invention relates to a pesticide composition and its application field, in particular to a three-component herbicidal composition with furasulcotrione, oxazicone and mefenacetamide as active ingredients, which is mainly used in paddy fields Weed control. Background technique [0002] Tefuryltrione: belongs to benzoylcyclohexanedione herbicides, the mechanism of action is 4-hydroxyphenylpyruvate dioxygenase inhibitor, which can inhibit the synthesis of indispensable pigments in plant growth, through the root , stems, young buds, and leaves absorb and conduct rapidly. Furansulcotrione can be used to control annual and perennial broad-leaved weeds in rice fields, both before and after buds. Grass, firefly rush, water sedge and other weeds of the Miscyrus genus, and broad-leaved weeds such as dwarf sagittarius, wild sagittarius, and water chestnuts that have become resistant to sulfonylureas in recent years are very effective. In addition, i...
