Abstract
The invention belongs to the field of agricultural herbicides, and in particular relates to a rice paddy herbicide containing a tribenuron-methyl and florasulam compounded composition. The invention aims to provide a compounded composition containing tribenuron-methyl and florasulam serving as active ingredients. By compounding, the prevention and control range is widened, the prevention and control effect is improved, and the pesticide consumption and agricultural cost are reduced. The technical scheme of the invention is that: in the compounded composition containing the tribenuron-methyl and the florasulam, the weight ratio of the tribenuron-methyl to the florasulam is 40:1-1:20; and the tribenuron-methyl and the florasulam account for 1 to 80 percent of the total weight of the compounded composition. The compounded composition has the advantages that: the synergism is achieved and the herbicide effect time is prolonged by compounding.
Description
Technical field
The invention belongs to the agricultural herbicide field, particularly contain the herbicide for paddy field of tribenuron-methyl and florasulam complex composition.
Background technology
Florasulam, chemical name are 2,6-, two fluoro-5-ethyoxyl-8-fluorine [1,2,4] triazoles [1,5-c] pyrimidine-2-sulfonanilides; Structural formula is:
It belongs to sulfonylurea herbicide, is typical inhibitor of acetolactate synthetase, and wheat crops and lawn are had high selectivity, and it is applicable to winter wheat, winter barley, spring wheat, spring barley, lawn, onion and meadow, range land etc.
Tribenuron-methyl, chemical name are 2-[4-methoxyl group-6-methyl isophthalic acid, 3,5-triazine-2-base (methyl) carbamyl amino-sulfonyl] benzoic acid or methyl esters; Structural formula is:
It belongs to sulfonylurea herbicide, is selective herbicide behind the sulfonylurea inner sucting conduction type bud.Can be by weeds cauline leaf, root absorption after cauline leaf is processed, and in vivo conduction, by hindering acetolactate synthestase, the biosynthesis of valine, isoleucine is suppressed, stop cell division, cause weeds dead.Broadleaf weed chickweed, shepherd's purse, conical silene herb, corn gromwell, ion grass, clearvers, Hairy Bittercress, tongue of sparrow grass, volume stem knotweed etc. are responsive to tribenuron-methyl, the medium sensitivities such as wartwort, Veronica.Observed weeds in 10-14 days after the dispenser and be subject to the severe inhibition effect, lobus cardiacus moves back green necrosis gradually, and blade moves back green, and generally whole strain was withered gradually in 30 days behind the winter wheat medicine, and dead plant strain growth is suppressed, and acts on slower.The anti-heterodynes such as field bindweed, Commelina communis, acalypha copperleaf, Armstrong, field thistle strengthen with dosage rising inhibitory action.The cereal crop tribenuron-methyl there is good drug resistance.
Through retrieval, do not find the document of tribenuron-methyl and the composite patent of florasulam.
The inventor has filtered out the compounded combination of tribenuron-methyl and florasulam through a large amount of desk research and field experiment, and various formulation products have been made in these combinations, thereby proposes the present invention.
Summary of the invention
The present invention aims to provide a kind of tribenuron-methyl and florasulam of containing as the complex composition of active ingredient, comes the expanding prevention scope by composite, improves control efficiency, reduces dosage and agricultural cost.
Another object of the present invention is to contain the complex composition of tribenuron-methyl and florasulam, is equipped with suitable auxiliary agent and makes operable formulation products.
Technical scheme of the present invention is: a kind of complex composition that contains tribenuron-methyl and florasulam, the weight ratio of its active ingredient tribenuron-methyl and florasulam is 40: 1～1: 20.
Described active ingredient tribenuron-methyl and florasulam total weight percentage in described complex composition is 1%～80%.

Except above-mentioned active ingredient tribenuron-methyl and florasulam, also comprise carrier and auxiliary agent in the described complex composition, to make wetting powder, oil-suspending agent or water dispersible granules.
Described carrier is selected from a kind of in vegetable oil or the filler.Wherein, vegetable oil is selected from one or more in corn oil, soybean oil, the castor oil; Filler is selected from one or more in white carbon, kaolin, precipitated calcium carbonate, diatomite, quartz sand, talcum powder and ammonium sulfate, sodium sulphate, sodium chloride, potassium chloride, the potassium sulphate.
Described auxiliary agent comprises a kind of surfactant at least.The surfactant formulation is emulsifier, dispersant, wetting agent or bleeding agent.Surfactant can be nonionic or anionic, also can be two or more compound uses.
Described emulsifier is selected from alkylphenol-polyethenoxy polyethenoxy ether, Ben-zylphenol Polyoxyethyl Ether, phenethyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether, polyoxyethylene carboxylate, phenethyl phenol polyethenoxy polyethenoxy ether, castor oil polyoxyethylene ether, alkylphenol polyoxyethylene formaldehyde condensation products, and in the phosphate neutralized salt of these compounds, alkyl benzene sulphonate (sodium salt or calcium salt) or the commercially available emulsifier monomer one or more.The newborn 500# of concrete example such as farming series, 600# is serial, 400# is serial, 1600# is serial, NP (OP) series, AEO is serial, BY is serial, this dish series, tween is serial and composite kind 2201,0201B, 0201C, 0203B etc.
Described dispersant; wetting agent; bleeding agent is selected from lignosulfonates (sodium salt or calcium salt); Negel; condensation compound of methyl naphthalene sulfonic acid and formaldehyde sulphate; how sulfonic formaldehyde condensation compound; methanonaphthalene sodium sulfonate dibutyl is sulfonic formaldehyde condensation compound how; N-methyl fatty acyl group sodium taurocholate; alkylphenol-polyethenoxy formaldehyde condensation products sulphate; the alkylphenol polyoxyethylene phosphate; the withered powder of tea; saponin; lignosulfite; fatty alcohol polyoxyethylene ether sulfate; lauryl sodium sulfate; neopelex; pull open among powder or the JFC one or more; can use separately, but also compound use.
Also organic solvent or cosolvent can be contained according to different formulations, also the functional aids such as antifreezing agent, thickener, stabilizing agent, defoamer can be added in case of necessity.
Described organic solvent, cosolvent are solvent naphtha series.
Described antifreezing agent is selected from one or more in ethylene glycol, glycerine, propane diols, urea or the diethylene glycol (DEG).
Described thickener is selected from one or more in xanthans, polyvinyl alcohol, bentonite, carboxymethyl cellulose, the aluminium-magnesium silicate.
Above-mentioned substance all is to well known to a person skilled in the art material, can buy by market.
The formulation of described complex composition is wetting powder, oil-suspending agent or water dispersible granules.
The present invention is mainly used in control wheat crops and lawn is had high selectivity, and it is applicable to winter wheat, winter barley, spring wheat, spring barley, lawn, onion and meadow, range land etc.Can use according to the common spray method that is watered.Lasting period to weeds of the present invention is relevant with the content of individualized compound in the composition, and is also relevant with the amount of application of composition.
Beneficial effect of the present invention is: the one, and composition shows fabulous synergistic effect in certain ratio range; The 2nd, because tribenuron-methyl is different from the mechanism of action of florasulam weed killer herbicide, there is not mutual pesticide resistance, can delay the pesticide resistance that alone tribenuron-methyl and florasulam weed killer herbicide produce, extend working time.
