Abstract

The invention belongs to the technical field of herbicides, and particularly relates to a compound weeding composition and a compound herbicide, the compound weeding composition comprises a weeding active component A and an auxin analogue; the herbicidal active component A is refined glufosinate-ammonium or a herbicidal active derivative thereof; the auxin analogue is diphenylurea or a derivative thereof, and comprises but is not limited to N, N-dimethyl-N, N-diphenylurea and 3, 4, 4 '-trichloro-sym-diphenylurea. According to the invention, the diphenylurea is matched with the refined glufosinate-ammonium for use under the physiological and biochemical action of a similar auxin mechanism in a plant body, so that the biological activity of the herbicide for killing weeds is improved, the weeding effect is maintained or increased, the unit dosage of the refined glufosinate-ammonium is reduced, and the resistance of the weeds to the refined glufosinate-ammonium is slowed down. In addition, compound herbicides of different dosage forms can be prepared by adopting the compound weeding composition and the auxiliaries, and the application is flexible and wide.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a compound herbicidal composition and a compound herbicide. Background technique [0002] L-Glufosinate-ammonium, also known as glufosinate-ammonium, was originally found from the active metabolite of biopesticide herbicide bialaphos in plants. Its herbicidal activity is twice that of ordinary glufosinate-ammonium, and the application amount per mu is only glufosinate-ammonium. 50% of the phosphine, and the application cost is basically the same. In 2006, a Japanese company successfully developed a single isomer of glufosinate-ammonium. [0003] Glufosinate-ammonium is a biocidal contact-killing herbicide for the treatment of weed stems and leaves. It has very good water solubility, stable structure and certain systemic effect. It is limited to the transfer from the base of the leaves to the top of the leaves. Amide synthase is the target enzyme. By inhibiting the...
