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: 18.5% bicyclic sulcotrione · chlorpyrazosulfuron · sapylphos water suspension concentrate

[0038] Bicyclic sulcotrione 10%, chlorpyrazosulfuron 0.5%, saponin 8%, alkylphenol polyoxyethylene ether sulfate 8%, hydroxymethyl cellulose 1.5%, sodium benzoate 0.2%, silicone compounds 0.3%, ethylene glycol 2%, and 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 18.5% bicyclic sulcotrione·chlorpyrazosulfuron-sulfuron-sulfuron-phosphorus 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: 25.5% bicyclic sulcotrione · pyrazosulfuron · sapylphos dispersible oil suspension concentrate

[0041] Bicyclic sulcotrione 10%, pyrazosulfuron-methyl 0.5%, saponin 15%, polyoxyethylene polyoxypropylene ether block copolymer 5%, nonylphenol polyoxyethylene ether 8%, magnesium aluminum silicate 2 %, peanut oil makes 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 25.5% bicyclic sulcotrione-pyrazosulfuron-methyl-sapylphos 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: 67.5% bicyclic sulcotrione · rimsulfuron · saponin water dispersible granules

[0044] 25% bicyclic sulcotrione, 2.5% sulfazone-methyl, 40% saponin, 10% naphthalene sulfonate formaldehyde condensate, 7% sodium alkyl sulfonate, 5% croscarmellose sodium, kaolin Top up to 100%. The above-mentioned materials are mixed in proportion, jet milled, mixed evenly, kneaded and granulated, dried and sieved to obtain 67.5% bicyclic sulcotrione · rimsulfuron · sapylphos 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 weeding composition containing benzobicylon, a sulfonylurea herbicide and anilofos. The weeding composition contains the following effective active components: benzobicylon,the sulfonylurea herbicide and anilofos, the sulfonylurea herbicide is selected from one of halosulfuron-methyl, pyrazosulfuron-ethyl, orthosulfamuron, bensulfuron methyl, propyrisulfuron and pyrazosulfuron, and the weight ratio of benzobicylon to the sulfonylurea herbicide to anilofos is (5-100) to 5 to (10-150). The weeding composition provided by the invention has a remarkable synergistic interaction effect, is capable of effectively preventing and removing multiple weeds of grassy weeds, cyperaceae weeds, broad leaf weeds and the like in rice fields, long in lasting period and safe to 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 bicyclic sulcotrione, sulfonylurea herbicide and saponin as effective active ingredients, which is applied to paddy fields Weed control. Background technique [0002] Bicyclic sulcotrione (benzobicyclon): It is an inhibitor of p-hydroxyphenylpyruvate dioxygenase (HPPD), which affects the synthesis of plastoquinone by inhibiting HPPD, and then acts on phytoene dehydrogenase by plastoquinone. (PDS), which ultimately affects the biosynthesis of carotenoids and causes leaf bleaching. It has very good effects on firefly sedge, special-shaped sedge, flat stalk, Yujiuhua, Yujiuhua, Moshangcai, Alisma, wild Arrowhead, young rice barnyardgrass, false rice, Qianjinzi, etc., especially It has outstanding control effect on Yinglin and Yujiuhua. [0003] Anilofos: It is an organophosphorus selective herbicide, which c...
