Abstract
The invention relates to a herbicide for a beet field. The herbicide composition comprises the following components in parts by weight: 15-25 parts of phenmedipham, 10-20 parts of acetochlor, 10-20 parts of glyphosate, 15-25 parts of dicamba, 25-35 parts of sodium dodecyl sulfonate and 45-55 parts of salad oil. The herbicide for the beet field has the beneficial effects that the herbicide composition is mainly used for controlling weeds in the beet field, and has a good weeding effect; the consumption and the application frequency of the herbicide are reduced, the pesticide effect lasting period is long, and the harm of weeds in the whole growth period can be effectively controlled after the herbicide is applied for once.
Description
Technical field
The present invention relates to herbicidal composition, particularly a kind of weed killer herbicide for beet ground.
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.
Phenmedipham: chemical name: 3-[(methoxy hydroxyl) is amino] phenyl-N-(3-aminomethyl phenyl-) carbamate
Pure compound is colourless crystallization, 0.25-0.3, fusing point 140-144 DEG C, decompose when 147 DEG C, under vapour pressure 25 DEG C of 1.32MPa. room temperatures, in water, solvability is 4.7mg/L, 200g/kg in acetone, 50g/kg in methyl alcohol, 2.5g/kg in benzene, differently strokes the former pharmaceutically active ingredient >97% of 231g/kg., fusing point 140-144 DEG C in your ketone.Easily decompose in alkaline medium.
Chloropropham after selectivity bud.Trade name: phenmedipham.Toxicity is lower.Slight excitant is had to skin and eyes.Lower to the toxicity of birds, lower to the toxicity of honeybee.
Mechanism of action: drug effect by soil types and humidity effect little.Temperature is very large to the drug effect of phenmedipham and beet safety effects, when temperature is more than 20 DEG C during spray medicine, is conducive to the absorption of medicament on blade face and plays drug effect, and the too high and suppressed easy generation poisoning of too low plant growth of temperature, sprays the appropriate to the occasion selection fine day of medicine and carry out.Not easily by rain in soil, about 25 days half life period.
Acetochlor: 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.
Glyphosate: be the weed killer herbicide developed by About Monsanto Chemicals.Also known as: glyphosate, agriculture reach (Roundup), careless dry phosphine, the sweet acid of phosphine.Sterling is non-volatile white solid, and proportion is 0.5, greatly about about 230 DEG C fusings, and with decomposing.Solvability when 25 DEG C in water is 1.2%, is insoluble to common organic solvents, and its isopropyl amine salt is dissolved in water completely.Non-combustible, do not explode, storage at normal temperature stablize.Corrosiveness is had to medium carbon steel, tin plate (tinplate).
Chinese another name: N-(phosphine carboxymerhyl) glycine; Agriculture reaches; ; Glyphosate; The sweet acid of phosphine; Glyphosate crude oil; 41% glyphosate isopropylamine salt water solution; Glyphosate (10% ammonium salt aqua); Soluble glyphosate pulvis; N-(phosphoric acid methyl) glycine; N-((phosphonomethyl)) amion acetic acid
A kind of non-selective, noresidue steriland herbicide, very effective to prennical root weeds, be widely used in rubber, mulberry, tea, orchard and sugarcane field.
Dicamba: belong to benzoic acid system weed killer herbicide, there is Uptake and translocation effect, have remarkable preventive effect to annual and perennial broadleaf weed.Dicamba is used for spraying after seedling, and medicament very soon by the leaf of weeds, stem, root absorption, can be conducted by phloem up and down, focuses mostly at meristematic tissue and the vigorous position of metabolic activity, hinders the normal activity of plant hormone, thus make it dead.The metabolic breakdown that carries out that can be very fast after gramineous plants absorption medicament makes it to lose efficacy, therefore the pesticide resistance that performance is stronger.Safer to gramineous crops such as wheat, corn, millet, paddy rice, dicamba disappears in soil after microorganism is comparatively fast decomposed, and both there will be lopsided curling symptom with latter general 24 hours broad leaved weeds, and 15-20 days dead.
Dodecyl sodium sulfate (Sodiumdodecylsulfonate, SDS), molecular formula is NaC
12h
25sO
3, molecular weight: 272.38.Be usually used in chemical industry and light and textile industries make emulsifier, flotation agent and penetrant.Dodecyl sodium sulfate and lauryl sodium sulfate are two kinds of different materials.
