Abstract

The invention discloses a compound weeding composition containing bispyribac-sodium and an application thereof. The active ingredients of the compound weeding composition are oxaflutole besilate and bispyribac-sodium. The compound weeding composition expands the weeding spectrum, has high selectivity to rice and barnyard grass, can be used for preventing and removing various gramineae, cyperaceae and broadleaf weeds at one time, and has an obvious prevention and treatment effect on monochoria vaginalis, barnyard grass, cyperus difformis, scirpus juncoides, eclipta prostrata, Lindernia crustacea (L.) F. Muell, potamogeton glomeratus, sagittaria trifolia, alternanthera philoxeroides and other weeds which are difficult to remove in rice fields; and the weeding composition has a prominent control effect on resistant weeds and is safe to crops. The compound weeding composition disclosed by the invention has a good synergistic effect, the application effect is obviously superior to the sum of theoretical effects of a single agent, the weeding effect is improved, the compound weeding composition has a super-superposition effect, and the harm of dominant weeds can be better controlled; in addition, the weeding composition reduces the dosage of the pesticide, reduces the phytotoxicity, also reduces the use cost and environmental pollution, and improves the safety for crops.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a compound herbicidal composition containing bispyribac and its application. 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 heteromorphic sedges has been gradually reduced, but the perennial wild arrowhead, Alisma and annual The hazards of Yujiuhua, duck tongue grass, wild water chestnuts, and Moshang vegetables are aggravated. There are also weeds such as Yinglin, Acupuncture, and cattle felt in the rice fields. [0003] The use of a single herbicide has a limited control spectrum ...
