Abstract

The invention discloses a bensulfuron methyl* fluoroglycofen-ethyl water emulsion which is prepared from the following raw materials and auxiliary agents in percentage by weight: 2-10 percent of bensulfuron methyl, 1-10 percent of fluoroglycofen-ethyl, 5-30 percent of dimethylbenzene, 2-20 percent of castor oil polyoxyethylene ether, 2-20 percent of oleic acid prenyl acetate, 2-20 percent of alkylphenol polyoxyethylene ether, 1-5 percent of propylene glycol, 1-5 percent of glycerol, 0.1-2 percent of xanthan gum and the balance of water. After the raw and auxiliary materials are mixed and dissolved, the water is added to be fully mixed, sheared and adjusted to obtain the bensulfuron methyl * fluoroglycofen-ethyl water emulsion. The bensulfuron methyl is inner adsorbing conduction type herbicide, and the fluoroglycofen-ethyl expresses contact killing activity; by mixing the bensulfuron methyl and the fluoroglycofen-ethyl, the bensulfuron methyl* fluoroglycofen-ethyl water emulsion has mutual promoting pesticide effect, obvious synergy and favorable preventing and removing effect on poaceae and broadleaves, and weeds in the whole growing period of a wheat field can be controlled by application once; and the two active components can be used as the herbicide of a paddy field, thereby being safe for rice which is the aftercrop of wheat.

Description

Bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion

Technical field

The present invention relates to a kind of complex weedicide---bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion that is used to prevent and treat weeds behind the wheat seedling, belong to technical field of pesticide.

Technical background

Current, the weeds of harm wheat mainly contain descurainia sophia (l.) webb ex prantl, shepherd's purse, clearvers, Veronica, chickweed, corn gromwell, etc. grassy weeds such as broad leaved weed and wild oat, amur foxtail, bromegrass, it is the most serious to be injured with winter wheat especially.At present, control for weeds behind the wheat paddock seedling, mainly be at wheat 2-4 leaf phase herbicide spraying, principal item is confined to 2,4 d butyl esters, 2 first, 4 chlorine, dicamba, bromoxynil octanoate, Bentazon and tribenuron-methyl etc. always, and is especially most widely used with tribenuron-methyl and complex preparation thereof.But grand etc. other of easy remaining metsulfuron-methyl, chlorine sulphur is difficult for composition of degraded in environment in the former medicine building-up process of tribenuron-methyl, to the wheat succession crop, has great potential safety hazard such as paddy rice, often owing to improperly cause the back stubble paddy rice underproduction even total crop failure.Because of tribenuron-methyl and complex preparation use for many years thereof, many places have produced weeds resistance biological strain on the other hand, and routine administration amount preventive effect descends, and certainly will will strengthen dosage in order to guarantee preventive effect.Like this, both increased drug cost, and made wheat produce recessive poisoning and the underproduction again easily.Therefore, press for and introduce a kind of new effective ingredient and prevent and treat weeds behind the wheat seedling.

Summary of the invention

Technical problem to be solved by this invention is, provides a kind of and is used for efficiently preventing and kill off weeds behind the wheat paddock seedling, and to the wheat succession crop---the bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion of rice safety.

Its technical scheme is: a kind of bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion, it is characterized in that: make: bensulfuron-methyl 2～10, fluoroglycofen-ethyl 1～10, dimethylbenzene 5～30 by following raw materials in percentage by weight and auxiliary agent, castor oil polyoxyethylene ether 2～20, oleic acid acid pears alcohol ester 2～20, alkylphenol polyoxyethylene 2～20, propane diols 1～5, glycerine 1～5, xanthans 0.1～2, water complements to 100.

Behind the above-mentioned supplementary material mixed dissolution, add water and fully mix shearing, adjustment, packing, promptly get bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion.

Its good effect is: the bensulfuron-methyl that bensulfuron-methyl fluoroglycofen-ethyl aqueous emulsion of the present invention is adopted and two kinds of active ingredients of fluoroglycofen-ethyl, wherein bensulfuron-methyl is the inner sucting conduction type weed killer herbicide, and fluoroglycofen-ethyl shows as contact toxicity, both use with, drug effect has mutual promoting action, have significant synergies, grass family and broad leaved weed are all had preventive effect preferably, enlarged single composition and killed the grass spectrum; And can prolong the preventive effect phase, a dispenser is the weeds in the controlled wheat paddock whole growing, has saved farming season, has reduced dosage, has saved drug cost, and environmentally friendly; Simultaneously, cultivate characteristics and actual rotation of crops arrangement situation according to China crops, the succession crop of wheat is mainly based on paddy rice, and two kinds of active ingredients of the present invention all can be used as the herbicide for paddy field use, therefore, to the rice safety of wheat succession crop.
