Description

A kind of weed killer herbicide

Technical field

The present invention relates to a kind of weed killer herbicide.

Background technology

Corn is normal edible grain in our daily life, but field is easy to growth of weeds while planting this crop, will affect like this growth of corn, so weeds need to be removed.At present conventional chemical method is carried out weeding, and the chemical agent using is mainly Acetochlor and thiameturonmethyl, because the drug effect phase of Acetochlor is short, therefore in the season of growth of corn, needs repeatedly medication, so not only take a lot of work, and cost is high; Although the herbicidal effect of thiameturonmethyl is good, the drug effect phase is longer, and price is higher, so also can cause cost to raise.

Glyphosate is a kind of efficient, low toxicity, the broad spectrum type steriland herbicide of low-residual, but the long-term use due to glyphosate single dose, make part weeds occur obvious resistance, some perennial malignant weed preventive effects are reduced, generally occur that herbicide is not thorough, do not kill root or medication a period of time weeds phenomenon of being revival from transplanting, unit are usage amount and the access times of glyphosate are increased, use cost increases simultaneously, reusing repeatedly also increased the residual risk of glyphosate in crops, do not meet very much the usage criteria of agricultural chemicals and be unfavorable for agriculture development, the problems such as being of current domestic use be take glyphosate as basic single dose or binary built composition are to increase weed control efficacies such as forest land, uncultivated areas, exists active ingredient low, and usage amount is large, cost of transportation height.Expand glyphosate composition herbicide spectrum for this reason, reduce unit are usage amount, access times and reduction use cost, non-dartboard crop is had again to higher safety is current urgent problem simultaneously.

Summary of the invention

Technical problem to be solved by this invention is to provide the weed killer herbicide that a kind of herbicidal effect is good and cost is low.

The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of weed killer herbicide, the raw material that comprises following parts by weight: Acetochlor 40-60 part, glyphosate 20-50 part, polyvinyl alcohol 1-5 part, the different monooctyl ester 3-10 of fluroxypyr part, acetone 3-8 part and surfactant 2-10 part.

The invention has the beneficial effects as follows:

Utilize glyphosate to depend merely on to inhale in pure cauline leaf conduction and fluoroglycofen-ethyl and the different monooctyl ester of fluroxypyr with cauline leaf, to tag, inhale in root the different mechanism combinations of conduction, make this triple combination have obvious synergistic effect.Glyphosate and salt thereof are a kind of steriland herbicides of low toxicity, can prevent and kill off all green plantss, but can by the metallic ion passivation in soil, be lost efficacy rapidly in soil, do not produce pollution problem; The different monooctyl ester of fluoroglycofen-ethyl and fluroxypyr belongs to the selective herbicide that the double inner sucting conduction type of tagging is prevented and kill off broadleaf weed, and broadleaf weed is all perennial weeds mostly; Effective combination of interior suction and two mechanisms of action of tagging, makes formula play synergistic effect.After dispenser, 4 hours weeds can show the symptom of being injured, and after the dispenser of traditional glyphosate single dose, 3 days ability shows the symptom of being injured, and this invention has improved quick-acting and the elimination efficiency to target weeds of weeding, has reduced the usage amount of unit are glyphosate; Reasonably proportioning combination, makes to improve under the prerequisite of weeding ratio, has lower cost.The triple combination formula of this invention is current environment protection water-based agent type preferably.This weed killer herbicide has improved preventive effect than traditional single dose, while having reduced weeding and farming interval time, has reduced labour intensity, has higher cost performance.Utilize the different mechanisms of three kinds of hypotoxicity weed killer herbicides, tag and interior suction complementation, strengthened there being the herbicidal effect of the malignant weed of resistance.And reasonably combination, both reduced residual to soil, strengthened the preventive effect to target crop simultaneously.

On the basis of technique scheme, the present invention can also do following improvement.

Further, the optimum value of described weed killer herbicide comprises the raw material of following parts by weight: 50 parts of Acetochlors, 30 parts of glyphosates, 3 parts of polyvinyl alcohol, 7 parts of the different monooctyl esters of fluroxypyr, 8 parts, 6 parts, acetone and surfactant.

Further, described glyphosate is any one in ammonium glyphosate, glyphosate potassium, glyphosate isopropyl amine salt, sodium glyphosate or glyphosate dimethylamine salt.

Further, described glyphosate is ammonium glyphosate.

Further, described surfactant comprises any one or the two or more mixing in fatty alcohol-polyoxyethylene ether fatty alcohol, polyethenoxy ether sodium sulfate, natural fatty alcohol polyoxyethylene ether ammonium sulfate, lauryl sodium sulfate, sodium naphthalene sulfonate, alcohol ether carboxylate, modified polycarboxylic acid salt, sorbitan mono-oleic acid ester, sodium lignin sulfonate, calcium dodecyl benzene sulfonate, methyl glucamine, alkyl phenol formaldehyde resin polyoxyethylene ether, sodium hexadecyl sulfate, castor oil polyoxyethylene ether or soybean lecithin.

Further, described surfactant is the mixing of fatty alcohol-polyoxyethylene ether fatty alcohol, lauryl sodium sulfate, modified polycarboxylic acid salt, sorbitan mono-oleic acid ester, sodium lignin sulfonate, sodium hexadecyl sulfate and soybean lecithin.

Glyphosate: formal name used at school N-((phosphonomethyl)) glycine, N-((phosphonomethyl)) amion acetic acid, Phosphonomethyl Imino Acetic Acid, is a kind of organophosphorus herbicide.Chemical formula: (HO) 2P (O) CH2NHCH2COOH.Glyphosate is the chronic wide spectrum steriland herbicide of inner sucting conduction type, the main interior enol acetonyl shikimene phosphate synthase of object that suppresses, thereby suppress shikimene to the conversion of phenyl alanine, cruel propylhomoserin and tryptophan, make synthetic being interfered of protein cause plant dead.Glyphosate is transmitted to each position of plant after absorbing by cauline leaf, can prevent and kill off unifacial leaf and plant dicotyledonous, annual and perennial, herbs and shrubs Deng40Duo section.After glyphosate buries, be combined and lose activity with the metal ion such as iron, aluminium very soon, seed hiding in soil and edaphon are had no adverse effects.

Fluroxypyr (the different monooctyl ester of fluroxypyr, English common name: fluroxypyr-mepthyl, chemical name: 4-amino-3, the different monooctyl ester of the fluoro-2-pyridine of the chloro-6-of 5-bis-fluoroacetic acid) inner sucting conduction type herbicide after seedling.After medicine, be absorbed by plants very soon, make sensitive plant occur the reaction of typical hormone herbicide, plant is lopsided, distortion.Drug resistance plant as wheat body in, fluorine grass surely can be combined into conjugates and lose toxicity, thereby has selectivity.Temperature without impact, but affects the speed of its drug effect performance to the final effect of its weeding.Generally when temperature is low, drug effect performance is slower, can make to stop growing after dunsiekte, but not dead immediately; After temperature raises, plant is very fast dead.In soil, leaching is not remarkable, and major part is distributed in 0-10 centimetre of topsoil, under the condition of aerobic, in the effect of edaphon, is degraded into very soon the non-poisonous materials such as 2-pyridine alcohol, in soil the half life period shorter, can not exert an influence to a lower batch broad leaf crop.Described surfactant main feature is: surfactant can be solid-state or liquid, can promote the absorption of weeds to above-mentioned composition, and environment is easily degraded, and meets environmental requirement.

Acetochlor is interior absorption acetamide-group herbicides, is selectivity preemergence herbicide.Can be absorbed by plant plumule, monocotyledon absorbs by bud scale, dicotyledon hypocotyl Assimilation and conductivity, must dispenser before weeds are unearthed, active ingredient RNA metabolism and protein in plant corpus is synthetic, and young shoot, young root are stopped growing, if be unearthed in the suitable young shoot of field moisture end, is killed, if soil moisture is few, after weeds are unearthed, with soil moisture, increase after weeds absorb medicament and work, grassy weed is to the bent atrophy of leaf roll, other leaf shrinkage, whole strain is withered.High to grassy weed activity such as lady's-grass, Amaranthus retroflexus is responsive, the broadleaf weeds such as lamb's-quarters, kitchen garden, black nightshade there is is certain preventive effect and suppress growth, specific activity grassy weed is low, Soybean Dodder is had to good preventive effect, the drug resistance Crop Acetochlors such as soybean are non-activity material in the rapid metabolism of body, normally use crop safety.
