Abstract
The invention relates to a weeding composition. The composition consists of the following components in parts by weight: 36 to 49 parts of 5-(methylamino)-2-phenyl-4-[3-(trifluoromethyl)phenyl]-3(2H)-furanone, 14 to 29 parts of ethoxylated styryl phenol, 23 to 36 parts of carfentrazone-ethyl, 15 to 27 parts of bentazone, and 11 to 19 parts of N-(phosphonomethyl)-glycine. The weeding composition is less in dosage, low in cost, short in residual life and safe for afterreap crops, and has excellent prevention and control effects to grassy weeds, broadleaf weeds and nutgrass flatsedge.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations.The invention still further relates to above-mentioned synergistic composition in the purposes of wheat with controlling weeds.
Technical background
Weeds are non-target cultivated plant in the farmland, and its main harm is to strive water, fertilizer, light, space with crops, also are the vectors of crop disease and insect simultaneously.China's wheatland crop smothering area accounts for 30% of wheat planting area, and wherein the area of serious harm accounts for 8%, and causing damage accounts for 15% of wheat gross yield, prevents and treats at present the method for farmland weed and mainly sprays insecticide.
The weeds that wheat growth stage need to be prevented and treated mainly contain the grassy weeds such as mouse tail amur foxtail, tall oat grass, perennial ryegrass, rough stalked blue grass green foxtail and as clearvers, lamb's-quarters, red heart lamb's-quarters, blank pipe lead a cow, broad leaved weed and the nutgrass flatsedge such as Amaranthus retroflexus, acalypha copperleaf, precious leaf mustard, corn sow thistle, white dead nettle, black nightshade, sinapsis alba.And metsulfuron-methyl, chlorine sulphur are grand, 2, the medicaments commonly used such as 4-d butyl ester, 2 first, 4 chlorine sodium salts, dicamba, fluroxypyr are often effective to class weeds wherein.And the grand longevity of residure of metsulfuron-methyl, chlorine sulphur can be grown, and is serious to poisoning such as rear stubble broad leaf crop such as cotton, soybean, peanuts; 2,4-d butyl ester is quick-acting, low-cost weed killer herbicide, but its drift is strong, easily does the deposits yields poisoning to contiguous, simultaneously, needs special-purpose sprayer, sprayer with after clean up difficulty; The unsuitable dispenser such as 2 first, 4 chlorine sodium salts, dicamba otherwise easily produces poisoning too late.
Summary of the invention
The invention provides a kind of Herbicidal combinations.
Said composition is comprised of the component of following weight portion; 5-(methylamino)-2-phenyl-4-[3-(trifluoromethyl) phenyl]-3 (2H)-furanone 36-49 parts; styryl phenol 14-29 part of ethoxylation, carfentrazoneethyl 23-36 part, Bentazon 15-27 part and N-((phosphonomethyl)) glycine 11-19 part.
It can be mixed with wetting powder or water dispersible granules.
It can be mixed with water dispersible granules.
Composition of the present invention can be widely used in the wheat crops such as winter wheat, spring wheat, barley and oat, effectively prevent and kill off annual and perennial broad leaved weed, such as lamb's-quarters, Amaranthus retroflexus, corn gromwell, clearvers, tongue of sparrow grass, common vetch, pale persicaria, acalypha copperleaf, black nightshade etc. and the grassy weeds such as vole tail amur foxtail, tall oat grass, perennial ryegrass, rough stalked blue grass green foxtail.
The invention provides a kind of Herbicidal combinations, its consumption is few, cost is low, grassy weed, broad leaved weed and nutgrass flatsedge are all had good control efficiency, the longevity of residure is short, to succession crop safety, in soil, can degrade rapidly, the longevity of residure is generally 30-60d, to safety such as rear stubble broad leaf crop such as cotton, soybean, peanuts, and has excellent synergy control efficiency.
