Abstract
The invention discloses a glufosinate and sulfometuron methyl containing compounded herbicide composition, wherein the weight ratio of glufosinate to sulfometuron methyl (effective components) is 10:(1-3). The glufosinate-sulfometuron methyl compounded herbicide composition is prepared into a suspension concentrate, and comprises effective components (glufosinate and sulfometuron methyl) and additives, wherein the additives comprise an emulsifier, an antifreeze agent, an antiseptic agent, a thickening agent, stuffing and water. The invention also discloses a method for preparing the compounded herbicide composition, and the method comprises the following steps: fully and uniformly mixing the raw materials in an enameled stirred tank, thus obtaining the glufosinate-sulfometuron methyl compounded herbicide composition in a suspension concentrate form. The compounded herbicide composition is low in toxicity, wide in herbicide controlling spectrum, good in quickly available and effect-persistent properties and low in cost, therefore, the compounded herbicide composition is an ideal variety for controlling weeds on non-cultivated lands; meanwhile, the compounded herbicide composition is simple and safe in use and good in environmental compatibility; and compared with other herbicide compositions, the herbicide composition disclosed by the invention is capable of slowing the generation of drug resistance, quick in weeding, wide in herbicide controlling spectrum and high in price-performance ratio.
Description
Technical field
The present invention relates to a kind of control uncultivated area weeds composition pesticide, particularly contain compound pesticide composition of careless ammonium phosphine and sulfometuronmethyl and preparation method thereof.
Background technology
In recent years, because a large amount of uses of various agricultural chemicals cause the agricultural weed pesticide resistance increasingly high; Like mouse tail amur foxtail, lady's-grass, barnyard grass, wild barley, Annual Ryegrass, green foxtail, setaria glauca, wild wheat, wild corn, perennial grassy weed and nutgrass flatsedge, as: duck bud, bent awns hairgrass, fescue grass; Or the like, harm is serious throughout the country, and is total in the control of chemical agent; Main at present use glyphosate, paraquat etc. all produce very strong pesticide resistance, and a mu using dosage increases year by year, and use cost increases year by year; And quick-acting is poor, and certain limitation is in use arranged.
Grass ammonium phosphine is a kind of organic phosphates weed killer herbicide, glutamine synthetase inhibitor, non-selective contact weedicide.Certain systemic action is arranged; Can be used for orchard, vineyard, uncultivated area weeding; Prevent and kill off annual or perennial dicotyledonous and grassy weed and nutgrass flatsedge etc., like mouse tail amur foxtail, lady's-grass, barnyard grass, green foxtail, wild wheat, wild corn, orchardgrass, fescue grass, bent awns hairgrass, yorkshire fog grass, perennial ryegrass, reed, annual bluegrass, wild oat, bromegrass, clearvers, benbie, deaf nettle, black nightshade, chickweed, quackgrass, bent grass, stroke son grass, field scorpion grass, Bermuda grass, Amaranthus retroflexus etc. with also can be used for potato.
Sulfometuronmethyl is a sulfonylurea herbicide, and it is synthetic to suppress branched-chain amino acid, thereby suppresses the cell division of plant strain growth end, stops weed growth to chlorosis downright bad.These article are steriland herbicide before the bud, behind the bud; Be applicable to that forest prevents and kill off annual and perennial grassy weed and broad leaved weed; Or open up the forest isolation strip; The cleaning of forest land, lumbering back, that the wasteland is cultivated is preceding, leisure uncultivated area, the wasteland weeding of roadside, road go out filling, like fescue grass, goldenrod, broomcorn millet, earth almona, johnson grass, artemisiifolia etc.
Summary of the invention
The present invention provides a kind of careless ammonium phosphine and sulfometuronmethyl compound pesticide composition of containing; Keep careless ammonium phosphine broad weed-killing spectrum to the effective advantage of control of weeds and the lasting effect of sulfometuronmethyl, interior absorption, and synergy is arranged, active high; Consumption is few, adapts to the requirement of China control uncultivated area weeds.
A kind of compound pesticide composition that contains careless ammonium phosphine and sulfometuronmethyl, the weight ratio of active ingredient grass ammonium phosphine and sulfometuronmethyl is 10: 1～3.
The formulation that contains careless ammonium phosphine and sulfometuronmethyl compound pesticide composition provided by the invention is an aqueous suspension agent, comprises active ingredient grass ammonium phosphine, sulfometuronmethyl and additive, and described additive comprises emulsifier, antifreeze, preservative, thickener, filler and water.
Described emulsifier is one or more in calcium dodecyl benzene sulfonate, NPE, AEO, the styrene phenol formaldehyde resin polyoxyethylene poly-oxygen propylene aether, with pesticide active ingredient emulsification, dispersion.
Described antifreeze is one or both in glycerine, the ethylene glycol, prevents that aqueous suspension agent is freezing at low temperatures, freezes.
Described preservative is one or both in Sodium Benzoate, the potassium sorbate, prevents that aqueous suspension agent microbial bacterial in storage from growing, go mouldy, corruption.
Described thickener is one or both in xanthans, the sodium carboxymethylcellulose, makes the aqueous suspension agent thickening, prevents the active ingredient cohesion in the aqueous suspension agent, layering.
Described filler is one or both in white carbon, the kaolin, as the carrier of pesticide original medicine, changes the rheological property of preparation.
The raw material weight percentage composition of described aqueous suspension agent is:
The weight ratio of grass ammonium phosphine and sulfometuronmethyl is 10: 1～3.
Preferably, the raw material weight percentage composition of above-mentioned aqueous suspension agent is:
The present invention also provides a kind of preparation method who contains careless ammonium phosphine and sulfometuronmethyl compound pesticide composition; Earlier emulsifier, antifreeze, preservative, thickener, filler, water in the additive are stirred in the enamel stirred tank fully; After mixing, add careless ammonium phosphine, sulfometuronmethyl again, and mix; Grind through sand mill again, process containing of suspending agent formulation of careless ammonium phosphine and the compound pesticide composition of sulfometuronmethyl.
The present invention adopts careless ammonium phosphine and the composite use of sulfometuronmethyl; Low toxicity, broad weed-killing spectrum, quick-acting and lasting effect good, nominal is to the extremely strong removing activity of weeds, and is with low cost; Can prevent and treat annual or perennial dicotyledonous and grassy weed and nutgrass flatsedge etc.; Be the comparatively desirable pesticide species of uncultivated area controlling weeds, use simple, safety, environmentally safe.The formulation of this compound pesticide preparation can be decided according to the enterprise production needs, has to produce many advantages such as simple, efficient, that cost is low, environment compatibility is good.This herbicidal composition has others existing other herbicidal compositions, and the ability suspension of pesticide resistance generation enlarges and kills the careless preventive effect to important weeds of composing, also improve.
