Abstract

The invention discloses a flumetsulam-containing weeding composition, which mainly takes flumetsulam, thifensulfuron methyl and acetochlor as main effective components, wherein the mass percent of the flumetsulam is 10-60%, the mass percent of the thifensulfuron methyl is 10-50%, and the mass percent of the acetochlor is 10%-50%. The weeding composition also comprises a dispersing agent, a salt-forming agent, a disintegrating agent, a wetting agent, a filler and water. The flumetsulam-containing weeding composition provided by the invention has an obvious synergistic effect after compounding according to a certain proportion, and has a good control effect on broadleaf weeds such as equisetum purpureum (jiegucao), shepherd's purse, erysimum cheiranthoides, descurainia sophia (maihao), polygonum, siberian cocklebur (laochangzi), solanum nigrum (wild grapes), amaranthus retroflexus (amaranth), chenopodium album (huicai), galium aparine L. (selayang), and datura stramonium in crops such as soybeans, corn, wheat, barley and oats.

Description

technical field [0001] The invention relates to the field of pesticide preparation, in particular to a herbicidal composition containing flumetsulam. Background technique [0002] Flumesulam is a typical acetolactate synthase inhibitor with strong systemic conductivity. It is a relatively slow process from the plant absorbing the drug to the occurrence of damage symptoms until the plant dies. By inhibiting the synthesis of branched-chain amino acids, protein synthesis is blocked, and plants stop growing and eventually die. Long residual effect period, broad herbicidal spectrum, suitable for soil, stem and leaf treatment. Thifensulfuron-methyl chemical is a highly efficient, broad-spectrum, selective systemic conduction post-emergent herbicide. With post-emergence treatment, sensitive plants almost immediately stop growing and die within 7-21 days. Adding surfactants can increase the activity of thifensulfuron-methyl on broadleaf weeds. At effective doses, crops such as s...
