Problems solved by technology

However, in recent years, due to the large-scale single and continuous use of some herbicide varieties, many weeds have developed resistance; Weeds and broad-leaved weeds often occur in a mixture, and a single herbicide species or a combination of two components can no longer effectively solve the above problems, and all of them will show some defects

Embodiment 1

[0037] Example 1: 33% Furansultrione · Fluoxetone Sulfame · Clopyrazosulfuron-methyl Aqueous Suspension Concentrate

[0038]Furansulcotrione 15%, Trifluorocarbazone 3%, Chlorpyrazosulfuron 15%, Alkylphenol Polyoxyethylene Ether Formaldehyde Condensate 12%, Sodium Alginate 3%, Potassium Sorbate 0.5%, Silicone Compound 0.1%, ethylene glycol 2.5%, deionized water 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 a 33% furansulcozone·flumesulam·clopyrazosulfuron aqueous suspension concentrate.

[0039] A new aqueous suspension formulation embodiment can be formed by replacing clopyrazosulfuron-methyl with one of pyrazosulfuron-methyl, rimsulfuron-methyl, bensulfuron-methyl, promasulfuron-methyl, and pyrazosulfuron-methyl.

Embodiment 2

[0040] Example 2: 30.5% Furansultrione · Fluoxetone Sulfame · Pyrazosulfuron-methyl Dispersible Oil Suspension Concentrate

[0041] Furansulcotrione 25%, Trifluorocarbazone 5%, Pyrazosulfuron-methyl 0.5%, Fatty Acid Ester Sulfate 15%, Castor Oil Polyoxyethylene Ether 10%, Magnesium Aluminum Silicate 2%, Turpentine 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 30.5% furansulcotrione·fluzonesulam·pyrazosulfuron-methyl dispersible oil suspension concentrate.

[0042] Replacing pyrazosulfuron-methyl with one of chlorpyrazosulfuron-methyl, rimsulfuron-methyl, bensulfuron-methyl, promasulfuron-methyl, and pyrazosulfuron-methyl can form a new dispersible oil suspension formulation embodiment .

Embodiment 3

[0043] Example 3: 61% Furansulcotrione·Fluoresonesulam·Erimsulfuron-methyl Water-dispersible Granules

[0044] 1% of furansulcotrione, 10% of fensulfame, 50% of rimsulfuron, 13% of polycarboxylate, 8% of Sapindus powder, 6% of sodium chloride, kaolin supplemented to 100%. The above-mentioned materials are mixed in proportion, air-jet pulverized, mixed evenly, kneaded and granulated, dried and sieved to obtain 61% furansulcozone·fluzonesulfazone·flumesulfuron water-dispersible granules.

[0045] A new embodiment of the water-dispersible granule formulation can be formed by replacing rimsulfuron-methyl with one of chlorpyrazosulfuron-methyl, pyrazosulfuron-methyl, bensulfuron-methyl, promasulfuron-methyl, and pyrazosulfuron-methyl.

Abstract

The invention discloses a weed-killing composition containing tefuryltrione, triafamone and sulfonylurea herbicide. The effective component of the weed-killing composition consists of the tefuryltrione, the triafamone and the sulfonylurea herbicide, wherein the sulfonylurea herbicide is selected from one of halosulfuron methyl, pyrazosulfuron ethyl, orthosulfamuron, bensulfuron methyl, propyrisulfuron and metazosulfuron; the weight ratio of the tefuryltrione to the triafamone to the sulfonylurea herbicide is (0.5-50):5:(0.5-50). The weed-killing composition disclosed by the invention is applied to control and removal of weeds in paddy fields; compared with single use of all single agents or mixed use of two components, the weed-killing effect is obviously improved, the weed-killing spectrum is expanded, the effect-lasting period is long and the weed-killing composition is safe to rice.

Description

technical field [0001] The present invention relates to the field of pesticide composition and application thereof, in particular to a herbicidal composition compounded with furansulcotrione, flunonesulam and sulfonylurea herbicides as effective active ingredients. Control of weeds in paddy fields. 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 a...
