The invention relates to the field of herbicides, in particular to a herbicidal composition containing flucetosulfuron and butachlor, which is used for solving the problems of large dosage and poor control effect when the flucetosulfuron and the butachlor are independently used at present. The herbicidal composition is prepared by reasonably compounding flucetosulfuron and butachlor, the herbicidal composition is applied to weeds in crop fields, the herbicidal composition is absorbed by the weeds after the herbicidal composition is applied, the action mechanisms of the flucetosulfuron and the butachlor are different, so that the weeds can be prevented and controlled by a single effect or a synergistic effect, and the herbicidal effect is obvious. According to the weeding composition, more weeds can be controlled by the weeding composition at the same time, the weed control spectrum can be expanded, an obvious synergistic effect is shown, the generation of drug resistance of the weeds can be delayed, and the use dosage of a single herbicide is reduced.

The present invention discloses a phosphorus-doped modified biochar material, its preparation method and application. The raw materials of this material include potassium dihydrogen phosphate and rice straw, and the mass ratio is 1:(100-800). Its preparation method includes the following steps: (1) Wash and dry the rice straw, and crush it into powder; (2) Add potassium dihydrogen phosphate particles into ultrapure water to make a potassium dihydrogen phosphate solution; (3) Add the rice straw powder into the potassium dihydrogen phosphate solution, stir and dry to obtain the dried phosphorus-doped rice straw material; (4) Carbonize the dried phosphorus-doped rice straw material to obtain a phosphorus-doped rice straw carbonized material; (5) Wash the phosphorus-doped rice straw carbonized material to remove ash, dry and crush it to obtain the modified biochar material. By using the rich pore distribution, high specific surface area and abundant surface functional groups of this material, the purpose of removing acetochlor, butachlor and metolachlor in environmental water bodies is achieved.

The invention relates to a herbicide composition, which comprises the following active ingredients: pendimethalin, butachlor and clomazone, and an optional herbicide safener. After the pendimethalin, the butachlor and the clomazone are compounded, compared with single agents and combinations of every two of the single agents, the pesticide composition has an obvious synergistic effect in the aspect of preventing and controlling agricultural weeds such as barnyard grass and dayflower. In addition, the herbicide composition can further comprise agriculturally acceptable auxiliaries and carriers, and can be prepared into agriculturally acceptable dosage forms. In addition, the invention also relates to an application of the herbicide composition for preventing and treating agricultural weeds.
