Abstract
Disclosed is a corn field weed control composition, which comprises stabilized and effective methoxone sodium salts and nicosulfuron, the weight portions of their effective constituents being 80:1 to 1:80.
Description
Affiliated technical field
The present invention relates to a kind of by mcpa sodium and the composite cornfield weeding composition bucket mixture that forms of nicosulfuron.
Background technology
Traditional weed killer herbicide kind of using in the present domestic corn field has mixture (as second green bristlegrass, first and second green bristlegrass, the different third careless green bristlegrass etc.), mcpa sodium, nicosulfuron of acetamide-group herbicides (as Acetochlor, propisochlor etc.), atrazine, acetamide-group herbicides and atrazine etc., and all there is certain defective in these weed killer herbicide types.Wherein acetamide-group herbicides can only be used as closed soil treatment, and generally can only suppress the sprouting of grassy weed, for the weeds and the broad leaved weed that are unearthed with sedge weed is invalid or invalid substantially.Atrazine is before inhaling optionally seedling in a kind of, herbicide after seedling, weeds are based on root absorption, cauline leaf absorbs seldom, weeds are had sealing process, also can kill the weeds that some have been unearthed, its shortcoming is that herbicidal spectrum is wideless, relatively poor for sedge weed and many grassy weed preventive effects, invalid substantially to the common weed rhizome of nutgrass flatsedge in the corn field, and its lasting period is longer, under the situation of large usage quantity second stubble crop wheat and other broad leaf crop is had certain influence.The mixture of acetamide-group herbicides and atrazine carries out soil treatment or can prevent and kill off various grassy weeds and broad leaved weed to weeds cauline leaf spraying at weeds 3-4 leaf before the phase corn field, but it is relatively poor to the sedge weed preventive effect, invalid substantially to the rhizome of nutgrass flatsedge, can cause certain influence to second stubble crop equally during large usage quantity.Mcpa sodium is a selective herbicide, and use is sprayed to the weeds cauline leaf and can be prevented and kill off convexutricle sedge herb in the corn field, Monochoria vaginalis, wild arrowhead and other broad leaved weed separately, and is very fast to sedge weed and broad leaved weed preventive effect, but can not prevent and kill off grassy weed.Spraying can prevent and treat multiple grass family, sedge family and part broad leaved weed to the independent use of nicosulfuron to the weeds cauline leaf, but invalid for some weeds such as acalypha copperleaf, Armstrong etc.
Summary of the invention
The purpose of this invention is to provide a kind of broad-spectrum weed-killing, the little effective cornfield weeding composition of consumption.
For the present invention that achieves the above object is a kind of cornfield weeding composition of realizing like this, comprise stabilizing effective mcpa sodium and nicosulfuron, the parts by weight of their active principles are 80:1 to 1:80; Mcpa sodium and nicosulfuron proportioning according to the above ratio are good, and packaged combination is used respectively, matching while using.Parts by weight the best of mcpa sodium and nicosulfuron active principle is 15～4:1.Mcpa sodium adopts pulvis; Nicosulfuron adopts oil suspending agent or pulvis.
Above-mentioned composition mu consumption 50 to 100 grams.
The advantage that said composition has been gathered mcpa sodium and nicosulfuron, in the field spraying entirely of corn 2-6 leaf phase, weeds 2-5 leaf phase, to corn and second stubble crop safety, to broad leaved weed and sedge weed preventive effect better and than very fast, grassy weed also there is better preventive effect, remedied the narrower shortcoming of corn field herbicide herbicidal spectrum of traditional type, disposable various grass family, broad-leaved and the sedge weed of preventing and kill off in the corn field of energy, and herbicidal effect is better, and is time saving and energy saving.Carrying out a large amount of field trials through my company proves, this product has special efficacy and instant effect for extremely difficult weeds that prevent and treat such as sarson, wheat volunteer, the rhizome of nutgrass flatsedge etc. in the corn field, resistance of rainwater washing against, can see careless dispenser, needn't wait rain, solved traditional weed killer herbicide need wait rain or irrigate the fields after could dispenser a difficult problem.Because it is poor that mcpa sodium and nicosulfuron mix the composition stable of back gained, remarkable reduction can appear in its drug effect after depositing a period of time, so when commercially producing, above-mentioned two kinds of materials that can proportioning is good are packing separately, sell after adding external packing again.During use two materials are mixed matching while using, better effects if.
Embodiment
Herbicidal composition of the present invention can be according to the production method preparation of pesticidal preparations field routine; Mcpa sodium and nicosulfuron all are commercially available.
This cornfield weeding composition, the parts by weight of mcpa sodium and nicosulfuron active principle are 80:1 to 1:80.Wherein parts by weight the best of mcpa sodium and nicosulfuron active principle is 15～4:1.Mcpa sodium adopts pulvis; Nicosulfuron adopts oil suspending agent or pulvis, and they preferably in the good ratio of proportioning, are divided into little packing, package separately; Be placed in the overall package, be used in combination matching while using.Composition mu consumption 50 to 100 grams of the present invention.
