Embodiment 1
[0038] Embodiment 1 A kind of herbicidal composition suspension
[0039] Formula: sulfasulfuron-methyl 25%, fluroxypyr 15%, bispyribac 10%, alkylphenol polyoxyethylene ether and its sulfate 5%, lignosulfonate 3%, organic ammonium salt 5% , organic bentonite 3%, methyl oleate make up to 100%.
[0040] Preparation method: Mix the above-mentioned components uniformly and pulverize them in a sand mill for 4 hours to form a coarse dispersion, and then go through wet ultra-fine pulverization to make the average particle size less than 5 μm to obtain the required 50% oxazole Sulfuron · fluroxyfen · bispyribac dispersible oil suspension concentrate products.
Embodiment 2～4
[0042] Using the method of Example 1, the composition suspension concentrate was prepared according to the formula in Table 1.

The herbicidal composition of the present invention is composed of sulfasulfuron-methyl, fluroxyfen and bispyribac in a mass ratio of 0.1-30:0.1-20:0.1-20. The application of the compound herbicide of the present invention in post-emergence weeding of paddy fields, especially in the application of controlling various gramineous weeds and broad-leaved weeds in paddy fields has remarkable effects. Compared with a single agent, the herbicide of the present invention can delay weed resistance, broaden the weeding spectrum, eliminate grass and broadleaf on the premise of improving the drug effect compared with a single agent, have long-lasting effect, and have reliable safety for rice and subsequent crops.
Description
technical field [0001] The invention belongs to the field of herbicides and relates to a herbicidal composition containing sulfasulfuron-methyl, fluroxypyr and bispyribac and an application thereof. Background technique [0002] Azimsulfuron (azimsulfuron), molecular formula C 13 h 16 N 10 o 5 S, chemical name: 1-((4,6-dimethoxypyrimidin-2-yl)-3-(1-methyl-4-(2-methyl-2H-tetrazol-5-yl)pyridine azole)-5-ylsulfonyl)urea. [0003] Structural formula: [0004] [0005] Fensulfuron-methyl is mainly used to control barnyardgrass, broad-leaved weeds and Cyperaceae weeds. Because it is rapidly metabolized into non-toxic substances in rice plants, it is safe for rice. Apply after rice seedlings, the dosage is 8-25g(a.i.) / ha. If used together with additives, the dosage will be lower. 20~25g(a.i.) / ha application can effectively control barnyardgrass, northern water hair flower, special-shaped sedge, purple water amaranth, eye vegetable, flower rush, alisma and so on. Its act...
