Abstract
The invention relates to herbicide for an orchard. The herbicide is prepared from the following components in parts by weight: 15-25 parts of sethoxydim, 10-20 parts of acetochlor, 10-20 parts of clethodim, 20-30 parts of bentazone, 20-30 parts of sodium dodecyl sulfate and 40-50 parts of salad oil. The herbicide composition is mainly used for preventing and controlling weeds in an orchard with good weeding effect, the dosage and application frequency are reduced, the acting period of the herbicide is long, and weed harm in the whole growth period can be effectively controlled by once application.
Description
Technical field
The present invention relates to herbicidal composition, particularly a kind of weed killer herbicide for orchard.
Background technology
Weed killer herbicide is in the market of a great variety, but most weed killer herbicide creates very large pollution to soil after use, changes soil structure, affects the mouthfeel of crop itself; And a lot of weed killer herbicide all can make seedling body itself sustain damage in use, affects its growth rate.
Sethoxydim: sethoxydim belongs to oxime herbicide, is have silk to divide inhibitor, almost has high activity to all grassy weeds, the invalid and safety to broad leaved weed.2-[1-(ethoxy imino) butyl]-5-[2-(ethylmercapto group) propyl group]-3-hydroxy cyclohexylphenyl-2-ketenes, molecular formula C

Physicochemical property: sterling is fluidity (low viscosity) liquid, relative density (d25) 1.043, boiling point >90 DEG C/3 × 10-5mmHg, vapour pressure <0.013mPa. distribution coefficient KowLogP=4.51/ (PH5).Solvability (mg/L, 20 DEG C) in water, 25 (PH4) 4700 (PH7).Can dissolve each other with methyl alcohol, ethane, ethyl acetate, toluene, octanol, dimethylbenzene, olive wet goods organic solvent, solvability >1kg/kg (25 DEG C). stability: under PH8.7 (25 DEG C) 10mg/L concentration and 12h/d (shining with helium lamp) condition, DT50=5.5d.DT50<1d (15 DEG C) in soil.Can not mixture with inorganic or organocopper compound.
Purposes: this product belongs to oxime herbicide, is have silk to divide inhibitor, almost has high activity to all grassy weeds, the invalid and safety to broad leaved weed.For broad leaf crop (cotton, flax, rape, potato, soybean, sunflower and vegetables), to use after 0.20-0.25kgAI/ha bud, prevent and kill off annual gramineous weed, prevent and kill off perennial weed with 0.20-0.5kg/ha, if additional 1-2L oil/ha preventive effect is better.
Acetochlor: Acetochlor is a kind of weed killer herbicide of extensive use.Being succeeded in developing in 1971 by About Monsanto Chemicals, is current one of most important weed killer herbicide kind in the world, is also one of maximum weed killer herbicide of current China usage amount.Acetochlor sterling is weak yellow liquid, and former medicine is because presenting peony containing impurity.Stable in properties, not volatile and photodissociation.Water insoluble, be soluble in organic solvent.Fusing point is greater than 0 DEG C, and vapour pressure is greater than 133.3pa, and boiling point is greater than 200 DEG C, not volatile and photodissociation.When 30 DEG C and the relative density of water be 1.11, the micro-223mg/l of the solvability in water.Be applicable to: corn, cotton, beans, peanut, potato, rape, garlic, tobacco, sunflower, castor-oil plant, shallot etc.Acetochlor is selectivity bud pre-treatment weed killer herbicide, hypocotyl mainly through monocotyledonous coleoptile or dicotyledon absorbs, and absorbs backward upper conduction, synthesizes and Cell growth inhibition mainly through hindering protein, weeds young shoot, young root are grown stop, so dead.The energy force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, so the effect of preventing and kill off grassy weed is better than broad leaved weed.About the 45 days lasting period in soil of Acetochlor, mainly through microbial degradation, the mobility in soil is little, mainly remains in 0-3 cm layer of soil.
Clethodim is a kind of novel dry land herbicide after seedling, has excellent selectivity.Be applicable to the grassy weeds such as the broad-leaved field Control Wild oats such as soybean, rape, cotton, peanut, lady's-grass, green foxtail, eleusine indica, annual bluegrass, hard grass.After dispenser, can be absorbed rapidly by grassy weed cauline leaf and conduct to stem apex and meristematic tissue, suppress merismatic activity, destroy cell division, finally cause weeds dead.
[English common name] clethodim
[chemical name] (±) 1 [(E)-3-chloroallyloxyamino imino group] propyl group 1 [2 one (ethylmercapto group) propyl group]-3-hydroxy cyclohexylphenyl-2-ketenes.
Bentazone is a kind of tool optionally contact killing type herbicide after seedling, for the process of weeds cauline leaf in seedling stage.Be mainly used in the crops such as paddy rice, soybean, peanut, wheat, prevent and kill off broad leaved weed and sedge weed, invalid to grassy weed.
