Abstract
The invention discloses a weeding composition for wheat fields. The composition comprises active components, a surfactant, a synergist, a solid carrier and a solvent diluent, wherein the active components are composed of fluoroglycofen, 2-ethylhexyl(4-chloro-2-methylphenoxy)acetate and fluroxypr-mepthyl, and the total weight of the active components of the weeding composition is 1-80%. The weeding composition has the characteristics of wide weeding spectrum, low residual, and good control effect on broad leaf weeds, so the control rate can reach above 90%; and the weeding composition costs low, has small damages to crops, and can basically control weeds in the fields for a whole season through one-time application.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations that is used for wheatland, belong to technical field of pesticide.
Background technology
Wheat is one of China staple crops, and the harm of wheatland crop smothering becomes the key factor of restriction Wheat Production.Can effectively control the crop smothering in the wheatland, stablize the high yield of wheat, also become one of major subjects of modern agricultural herbicide research.Thereby plantation peasant household just needs to select a kind of efficient and to the weed killer herbicide of crop safety.Mostly there is the narrow problem of herbicidal spectrum in cornfield herbicidal in the market, can not play extraordinary effect to Tanaka's broad leaved weed effectively.
Summary of the invention
The present invention is directed to the problem in the background technology, a kind of Herbicidal combinations that is used for wheatland is provided, purpose is: can not only prevent and treat broad leaved weed, enlarge and kill the grass spectrum, and effect be remarkable.
Technical solution of the present invention:
A kind of Herbicidal combinations that is used for wheatland is characterized in that: said Herbicidal combinations comprises active component, and active component is made up of fluoroglycofen-ethyl, the different monooctyl ester of MCPA,MCP,methoxone and the different monooctyl ester of fluroxypyr.
The active component of said Herbicidal combinations is 1～80% of a gross weight.
Said Herbicidal combinations also comprises surfactant, synergist, solid carrier and solvent diluent.
The proportioning of said fluoroglycofen-ethyl, the different monooctyl ester of MCPA,MCP,methoxone, the different monooctyl ester of fluroxypyr is 1～50: 1～50: 1～50.
Said surfactant is alkylnaphthalene sulfonate, alkylsulfonate, lignosulfonates, lauryl sulfate, calcium dodecyl benzene sulfonate, APES, polycarboxylate, carboxymethyl cellulose, farming breast 500, farming breast 600, Nongru-700, farming breast 2201, farming breast 8209, farming breast 8316, farming breast 8312, agricultural newborn NP-10, dispersing agent NNO, Nekal BX or detergent LS.
Said solid carrier is bentonite, white carbon black, kaolin, precipitated calcium carbonate, sodium sulphate, ammonium sulfate, diatomite, starch or potter's clay.
Said solvent diluent is methyl oleate, acetophenone, mineral oil, vegetable oil, diformazan trident maple, S-150, S-200, propane diols or water.
Said Herbicidal combinations uses a kind of surfactant, a kind of solid carrier or solvent diluent at least.
Said Herbicidal combinations is processed following dosage forms: oil suspending agent, missible oil, wetting powder, water dispersion granule, dried outstanding agent, suspending agent, aqueous emulsion, microemulsion.
Beneficial effect of the present invention:
This Herbicidal combinations weeding spectrum width, low-residual all has good control efficiency to broad leaved weed, and control rate reaches more than 90%; And cost is low, and is little to the injury of crop, but the harm of disposable dispenser basic controlling wheatland weeds of whole season.
Embodiment
Below in conjunction with embodiment the present invention is done further elaboration.
The active component of Herbicidal combinations is mixed by the different monooctyl ester of fluoroglycofen-ethyl, the different monooctyl ester of MCPA,MCP,methoxone and fluroxypyr and forms; The proportioning of fluoroglycofen-ethyl, the different monooctyl ester of MCPA,MCP,methoxone, the different monooctyl ester of fluroxypyr is 1: 8.6: 5, and active component is 51% of a gross weight.
Get the different monooctyl ester of fluoroglycofen-ethyl 3.5%, MCPA,MCP,methoxone 30%, the different monooctyl ester 17.5% of fluroxypyr; Alkylnaphthalene sulfonate 8%, APES 5%, polycarboxylate 3% and water 33%; Pour in the disperser each component is disposable; Be uniformly dispersed, and control water oil droplet diameter is at 1～10 micron.
The drug effect report: 5～7 phases of wheat, 4～5 phases of weeds, 30 days anti-effects of investigation strain are following behind the medicine:
This result shows: herbicidal effect will be higher than arbitrary single agent in the component behind the mixing adapted of fluoroglycofen-ethyl, the different monooctyl ester of MCPA,MCP,methoxone, the different monooctyl ester of fluroxypyr, helps increasing mutually drug effect, and enlarges grass spectrum extremely.
