Problems solved by technology

[0007] In recent years, weeds in rice fields have become more and more serious. After several years of field investigation and practice, it has been found that the dominance of malignant weeds in the field is becoming more and more obvious, such as barnyardgrass, rice barnyardgrass, Alisma, bermudagrass, arrowhead, and firefly. However, using butachlor alone for control and control, too high a dosage will cause certain damage to rice, and the risk of phytotoxicity is relatively high. Therefore, it is urgent to develop an efficient, safe, and cost-effective herbicide to ensure that weeds in the field can be controlled by one application, and the crops can be guaranteed. Yield

Embodiment 1

[0044] (embodiment 1) suspoemulsion

[0045] 32% bicyclic sulcotrione · oxaziclodione · butachlor suspoemulsion: 6% bicyclic sulcotrione, 1% oxacitrione, 25% butachlor, 5% solvent naphtha, polyoxyethylene polyoxypropylene embedded Segment copolymer 2%, fatty alcohol polyoxyethylene ether phosphate 3%, propylene glycol 3%, tristyrylphenol polyoxyethylene polyoxypropylene ether 5%, and deionized water make up 100%. (Above content is mass percent content, the same below).

[0046] The specific processing steps of the suspoemulsion composition are as follows: first mix and dissolve butachlor and mineral spirits according to the above formula, then add tristyrylphenol polyoxyethylene polyoxypropylene ether, and mix uniformly to prepare mixture A for use.

[0047] According to the above formula, add polyoxyethylene polyoxypropylene block copolymer, fatty alcohol polyoxyethylene ether phosphate and propylene glycol into water, stir evenly, then add bicyclic sulcotrione and oxazicloz...

Embodiment 2

[0049] (embodiment 2) dispersible oil suspension

[0050] 64% bicyclic sulcotrione · oxaziclodione · butachlor dispersible oil suspension concentrate: bicyclic sulcotrione 12%, oxaziculone 2%, butachlor 50%, alkylphenol polyoxyethylene ether formaldehyde condensation 10% calcium dodecylbenzenesulfonate, 10% calcium dodecylbenzenesulfonate, 1% organic bentonite, 1% white carbon black, and 100% methyl oleate. (Above content is mass percent content, the same below).

[0051] Preparation method: the above materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to obtain a 64% bicyclic sulcotrione·oxaziclodione·butachlor dispersible oil suspension concentrate.

Abstract

The invention discloses a weeding composition containing benzobicyclon, oxaziclomefone and butachlor. The active ingredients of the weeding composition are benzobicyclon, oxaziclomefone and butachlorin a weight ratio of (0.5-50):2:(0.5-100). The weeding composition disclosed by the invention has a remarkable synergistic effect, and compared with single use of each single agent or mutual binary compound use, the weeding composition has obviously improved weed control effect, and expands the weeding spectrum. The action mechanisms of the weeding composition are different, action sites are increased, generation of drug resistance of weeds can be delayed, and the service life of pesticides is prolonged. According to the weeding composition disclosed by the invention, the effective use amountof pesticides is reduced, the use cost is reduced, and the pollution to the environment is alleviated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a three-component compound herbicidal composition for controlling weeds in paddy fields with bicyclic sulcotrione, oxazone and butachlor as effective active ingredients. Background technique [0002] Rice is one of the main crops in our country. For a long time, barnyardgrass, syringa, and three-edge grass (including Japanese sedge, flat stalk, and three-edge grass, etc.) have been the three major harmful weeds in rice fields; in addition, some Due to the long-term and continuous use of pyrazosulfuron-methyl, bensulfuron-methyl and other pesticides in the area, the damage of the more serious malignant weeds Azalea and special-shaped sedges has been gradually reduced, but the perennial wild arrowhead, Alisma and annual The hazards of Yujiuhua, duck tongue grass, wild water chestnuts, and Moshangcai have increased. There are also weeds such as Yinglin, Acupuncture, ...
