Abstract
The invention discloses a herbicide composition containing florasulam and flumetsulam. The effective components of the herbicide composition are florasulam and flumetsulam, and the mass fraction of the florasulam and the flumetsulam in the composition is 20:1 to 1:20. According to practical application, the composition disclosed by the invention can be prepared into a suspension concentrate, an oil suspension, wettable powder or a water dispersible granule, and is applied to control broadleaf weed in wheat fields; the control effect of the composition is obviously better than that of a single component used alone, and the herbicidal spectrum is increased. Besides, the consumption of the herbicide composition is reduced, the generation of herbicide resistance is delayed, and pollution to the environment is reduced.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically take florasulam and Flumetsulam as the composite binary complex of active ingredient, be applied to the control of wheat paddock broad leaved weed.
Background technology
Chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because some weed killer herbicide kind large area are used separately, caused a lot of weeds to produce pesticide resistance.Meanwhile, while occurring due to weeds, grass is complicated, of a great variety mutually, and single variety is used can not effectively solve farmland weed, all can show defect in a certain respect.And the use that is mixed of variety classes weed killer herbicide, have herbicidal spectrum wide, promote preventive effect, delay the plurality of advantages such as weeds develop immunity to drugs, save time, saving of labor.
Florasulam (florasulam), belongs to triazolopyrimidine sulfonamides herbicide, has interior suction conduction, can conduct to weeds complete stool, thereby herbicide is thorough, can not recur.Efficacy stability at low temperatures, even still can guarantee to stablize drug effect in the time of 2 ℃, this point is that other weed killer herbicides are incomparable.Be mainly used in controlling broad leaved weed in wheat field, as clearvers, corn gromwell etc.
Flumetsulam (flumetsulam), belongs to triazolopyrimidine sulfonamides herbicide, and the mechanism of action is suppress acetolactate synthestase synthetic, and by suppressing the synthetic protein biosynthesis block that makes of branched-chain amino acid, plant stops growing.Longevity of residure length, broad weed-killing spectrum, soil, cauline leaf are processed and all can.Be suitable for the Tanakas such as corn, soybean, wheat, barley prevent and treat life in 1 year and perennial broadleaf weed as meadow pine, shepherd's purse, wallflower, pepper grass, broadcast ma wormwood artemisia, knotweed, Veronica, Siberian cocklebur, black nightshade, Amaranthus retroflexus, lamb's-quarters, piemarker, clearvers, datura etc.
By the screening of different pesticide species compounded formulas, select outstanding formula and can effectively improve the actual control efficiency to disease, worm, crop smothering, reduce dosage, reduce costs, delaying disease, worm, the drug-fast generation of crop smothering, is the important means of the upper disease of agricultural, worm, the crop smothering comprehensive regulation.The inventor conducts in-depth research the compounded formula screening of florasulam and Flumetsulam, find that florasulam and Flumetsulam carry out composite, in certain compound proportion scope, wheatland broad leaved weed is had to synergistic effect, after further study, completed the present invention.
Not yet find at present the Patents report that florasulam and Flumetsulam are composite.
Summary of the invention
When the object of the invention is to solve prior art Pesticides single dose and using separately to wheat weeds easily develops immunity to drugs and actual control efficiency is poor problem, a kind of efficient, wide spectrum, economy, safety are provided, are conducive to the Herbicidal combinations of the wheat weeds comprehensive regulation.
Technical scheme of the present invention is: the invention provides a kind of Herbicidal combinations that contains florasulam and Flumetsulam, active ingredient florasulam and Flumetsulam and suitable agricultural chemicals auxiliary element, consist of.Florasulam and Flumetsulam in composition ratio of quality and the number of copies be 20:1～1:20.
Described Herbicidal combinations can, according to well known to a person skilled in the art method, can be processed into the application forms using in the applicable agricultural productions such as suspending agent, oil-suspending agent, wetting powder and water-dispersible granules.
The auxiliary element using in present composition application forms comprises that emulsifier, wetting agent, disintegrant, dispersant, thickener, defoamer, antifreezing agent, carrier etc. are of value to active ingredient and in preparation, stablize and bring into play the known substance of drug effect, be all various compositions conventional in pesticidal preparations or that allow to use, concrete composition and consumption require to determine by test according to formula.
Described emulsifier can be one or more the mixing in alkylphenol polyoxyethylene phosphate, alkylphenol polyoxyethylene phosphate, diphenyl phenol polyethenoxy polyethenoxy ether, styrenated phenol APEO, diphenyl phenol polyethenoxy polyoxy formaldehyde condensation products, fatty alcohol-polyoxyethylene ether, polyoxyethylene carboxylate, nonyl phenol polyoxyethylene polyoxypropylene ether etc.
Described wetting agent can be lauryl sodium sulfate, aerosol-OT salt, sodium butylnaphthalenesulfonate, fatty acid amide N methyl taurine sodium salt, lignosulfonates, alkylphenol polyoxyethylene phosphate, petroleum sodium sulfonate, fatty acid ester sulphate, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, pull open one or more the mixing in powder, the withered powder of tea, spaonin powder, soapberry powder etc.
Described disintegrant can be one or more the mixing in sodium bicarbonate, magnesium chloride, aluminium chloride, sodium chloride, urea, ammonium sulfate, bentonite etc.
Described dispersant can be one or more the mixing in sodium methylene bis-naphthalene sulfonate, sodium lignin sulfonate, fatty acid amide N methyl taurine sodium salt, alkylphenol polyoxyethylene sulphate, polycarboxylate, lignosulfite, fatty acid ester sulphate, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether etc.
Described thickener can be one or more the mixing in polyvinyl alcohol, polyvinyl acetate, xanthans, gelatin, gum Arabic, polyvinylpyrrolidone, aluminium-magnesium silicate, phenolic resins, methylcellulose, sodium alginate etc.
Described defoamer can be one or more the mixing in epoxidized soybean oil, methyl alcohol, silicone oil etc.
Described antifreezing agent can be one or more mixing in glycerine, propane diols, diethylene glycol (DEG), urea etc.
Described carrier can be one or more the mixing in precipitated calcium carbonate, potter's clay, kaolin, diatomite, bentonite, white carbon, clay, talcum powder, quartz sand, soybean oil, corn oil, rapeseed oil, turpentine oil, methyl oleate, cocoa butter, palm oil.
The frequency of administration of the present composition and amount of application have small variations with factors such as weed growth situation, weather condition variations, can be by using suitable spraying times and dosage to reach the object of effective control.
Compared with prior art, the invention has the advantages that:
1, florasulam and Flumetsulam compositely have synergistic function, than the independent use of single dose, have obviously improved the control efficiency to wheatland broad leaved weed, and have expanded herbicide spectrum.
2, two kinds of active ingredients of florasulam and Flumetsulam are composite, reduced agricultural chemicals usage amount, reduced resistance risk, reduced use cost, Environmental compatibility is good.
