Problems solved by technology

Tribesulfuron-methyl is a selective systemic conduction herbicide, which can be absorbed by the roots and leaves of weeds, and conduct in plants. By inhibiting the activity of acetolactate synthase, it affects the biosynthesis of branched-chain amino acids. It manifests as growth point necrosis, leaf vein chlorosis, plant growth is severely inhibited, dwarfed, and eventually the whole plant dies. Sensitive weeds stop growing immediately after absorbing the pesticide, and die after 1-3 weeks. Applicable crops are wheat, barley, and barley , oats, the control targets are mainly various annual broad-leaved weeds, and the effect is better on Artemisia solani, shepherd's purse, broken rice shepherd's purse, Maijiagong, quinoa, amaranth, etc. It also has a certain control effect on field thistle, Polygonum curliculus, field bindweed, lacquer, etc., and has no effect on grass weeds such as wild oats, kangaroo, brome, and sycamore

Abstract

The invention discloses a preparation method of a tribenuron-methyl and quinclorac micro-emulsion and belongs to the field of herbicides. The micro-emulsion includes 12-13% of tribenuron-methyl water dispersing granules, 5-6% of quinclorac, 15% of diethyl ether, 4% of ethyl acetate, and 63% of water, and is prepared by blending the components under special conditions. The preparation method uses general devices, has simple processes and mild reaction conditions and is free of pollutant emission. The tribenuron-methyl and quinclorac are compounded, so that the micro-emulsion has synergistic effect. By compounding the two herbicides with auxiliary materials, the micro-emulsion is significantly higher than single tribenuron-methyl or quinclorac in prevention effect on weeds in paddy rice fields and is greatly enhanced in herbicidal effects, and especially has special effects on older barnyard grass. The micro-emulsion also is available in a dry farmland.

Description

technical field [0001] The invention belongs to the field of herbicides, in particular to a preparation method of a microemulsion of tribenuron-methyl and barnyardgrass. Background technique [0002] Trisulfuron-methyl, also known as Broadleaf, is slightly soluble in water and organic solvents. The commonly used dosage forms are 10% Tribenuron-methyl WP and 75% Tribenuron-methyl Water-dispersible Granules. Tribesulfuron-methyl is a selective systemic conduction herbicide, which can be absorbed by the roots and leaves of weeds and conduct in the plant body. By inhibiting the activity of acetolactate synthase, it affects the biosynthesis of branched-chain amino acids. It manifests as growth point necrosis, leaf veins chlorosis, plant growth is severely inhibited, dwarfed, and eventually the whole plant dies. Sensitive weeds stop growing immediately after absorbing the pesticide, and die after 1-3 weeks. Applicable crops are wheat, barley, and barley , oats, the control object...
