Herbicide containing halosulfuron-methyl

Abstract

The invention relates to the technical field of pesticide compositions, in particular to a herbicide containing halosulfuron-methyl. The active ingredients of the herbicide are the halosulfuron-methyland methyl iodosulfuron, wherein the mass ratio of the halosulfuron-methyl to the methyl iodosulfuron is (2-5): (3-15). The herbicidal activity of the compounded halosulfuron-methyl and methyl iodosulfuron in the herbicide is higher than that of the separately used halosulfuron-methyl and methyl iodosulfuron for broadleaf grass and cyperaceae, and a synergistic effect is achieved; a weed controlspectrum is enlarged after the combination, and the dosage is also reduced; after the halosulfuron-methyl and the methyl iodosulfuron are compounded, the synergistic effect is shown within a certain ratio, the control effect of the composition is obviously improved than single agents, the dosage of a pesticide is reduced, the use frequency of the pesticide is reduced, the use cost of the pesticideis reduced, the adverse effect of the pesticide on the ecological environment is reduced, and the maintenance of the ecological balance is facilitated.

Background technique [0002] The main weeds in the corn field are: crabgrass, amaranthus, cyperus, amaranth, teff, nightshade, barnyardgrass, millet, quinoa, gray-green quinoa, purslane, amaranthus, pig Hairy cabbage, Kochia, amaranth, foxtail, amaranth, amaranth, quinoa, green amaranth, goosegrass, green weed, thorn quinoa, amaranth, velvetleaf, wild watermelon seedlings, amaranth and other weeds. Perennial weeds include bindweed, reed, Cyperus cyperus, etc. [0003] The common weeds in wheat fields mainly include Aurantia chinensis, Japanese sagegrass, sage grass, clubhead grass, hardgrass, bluegrass, candle grass, wild oats, brome, poisonous wheat, rice chaste, mountain bittern, mud Cucumber, endive, annual capsicum, spinach, chickweed, beef chickweed, cocklebur, Maijiagong, large vetch, narrow-leaf vetch, wide-sprea...

AI Technical Summary

Problems solved by technology

[0004] Wheat fields and corn fields are generally planted on a large scale, and manual weeding is unrealistic. Traditional herbicides have a narrow weeding spectrum, and cannot use weeds in corn fields and weed fields at the same time, and the weeding effect is poor, causing great damage to crops.
