Abstract

The invention discloses a synergic herbicide comprising effective constituents and auxiliary materials, the effective constituents include mixture of bispyribac sodium and cyhalofop-butyl, wherein the percentages by weight of the constituents include, bispyribac sodium 1-45%, cyhalofop-butyl 1-45%. The rice field herbicide has low cost.

Description

technical field [0001] The present invention relates to pesticides, especially a kind of herbicide technology. Background technique [0002] Bispyribac ether: other names in Chinese are Yiqi, bispyrimidine salicylate, common name in English: bispyribac-sodium, is a pyrimidine salicylic acid herbicide. Mechanism of herbicidal action: Inhibitor of acetolactate synthase (ALS), works by preventing the biosynthesis of branched-chain amino acids. Absorbed through the stems, leaves and roots, and transmitted in the plant, the weeds stop growing and then die. It has high selectivity, is safe for crops, humans, livestock and beneficial organisms, and basically has no pollution to the environment. Bispyribac is mainly used for the control of annual and perennial weeds after direct-seeding rice seedlings, and has special effects on barnyardgrass (it is effective on barnyardgrass at the 1-7 leaf stage, and the control effect is especially good at the 3-6 leaf stage), , Barnyardgrass,...
