Abstract
The invention belongs to the complex weedicide in pesticide herbicide field, specifically glyphosate and imazethapyr.Herbicide is with glyphosate-class herbicides and imazethapyr as active component, and glyphosate-class herbicides (in terms of glyphosate) is 10 15:1 with the mass fraction ratio of imazethapyr.Described herbicide is as resistance glyphosate genetically modified crops herbicide formulations.Herbicidal composition of the present invention improves control of weeds effect, expands weed control spectrum.Annual gramineous weed and part broad leaved weed preventive effect are highlighted by glyphosate class herbicides compounds, but poor to perennial weeds and part broad leaved weed preventive effect.Use and glyphosate is compounded with imazethapyr, improve broad leaved weed and the preventive effect of the part malignant weed of tolerance glyphosate, therefore this complex weedicide combines the activity of weeding of glyphosate and both imazethapyrs, and for relatively glyphosate and imazethapyr single dose, decrease Pesticide use amount, reduce use cost, it is simple to popularization and application.
Description
Technical field
The invention belongs to the compounding weeding in pesticide herbicide field, specifically glyphosate and imazethapyr
Agent.
Background technology
Glyphosate (glyphosate), has another name called glyphosate, agriculture reaches (Roundup) etc., and its chemical name is:
N-((phosphonomethyl)) glycine, is a kind of organophosphor weeding developed by Monsanto Chemicals for 1971
Agent.
Glyphosate is the most most economical Uptake and translocation nonselective herbicide, and it mainly passes through stem
Leaf absorbs, and conducts under ground portion, suppresses enolpyruvyl shikimene phosphonic acids synzyme in plant, from
And shikimene converts to phenylalanine, tyrosine and tryptophan in suppressing plant, it is that protein synthesis is subject to
To interference, cause weeds dead.
Due to the good characteristic of glyphosate, exploitation and the plantation of resistance glyphosate genetically modified crops increase in recent years
Long rapid, glyphosate has become the first in the world big genetically modified crops herbicide-tolerant kind.But for many years
During use, the resistance of glyphosate has been produced by part susceptible weeds.
Imazethapyr (amicarbazone) chemical name: 2-[4,5-dihydro-4-methyl-4-(1-
Methylethyl)-5-oxo-1H-imidazoles-2-base]-5-ethyl-Niacin Nicitinic Acid, belong to imidazolone type weeding
Agent, i.e. branched-chain amino acid biosynthesis inhibitor, medicament is absorbed by root, leaf, and conduction is to separate living tissue
In, it is that plant growing is obstructed.Semen sojae atricolor can be thus very strong to this medicine patience, before belonging to bud by its rapid metabolization
And getting up early selective herbicide after Seedling.Prevent and kill off Soybean Field and other leguminous plant field grassy weeds and some
Broad leaved weed.
The preparation of glyphosate mainly has water preparation, soluble granula, soluble powder etc. at present.Compounding system
Agent has glyphosate dicamba aqueous solution, glyphosate 2 first 4 chlorine water agent etc..Patent (CN1268297A)
Report glyphosate and Dicamba complex preparation, be used for preventing and kill off crop no-tillagely, fallow land, orchard, nursery
Annual and perennial weeds.Patent (CN101773143A) report glyphosate compounds with glufosinate-ammonium.
Patent (CN1268296A) report glyphosate and isopropyl methoxalamine compound, for dry crop such as Cotton Gossypii,
No-tillage ground weeding before the sowing such as Semen sojae atricolor, Semen Maydis, Sorghum vulgare Pers., Semen arachidis hypogaeae.Imazethapyr preparation mainly have water preparation,
Wettable powder, cream etc..Complex preparation has imazethapyr different grass pine cream, imazethapyr fluorine
Sulfanilamide grass ether bentazone water preparation, imazethapyr Quizalotop-ethyl Fluosulfonamide oxalether cream, imidazoles second
Nicotinic acid imazaquin water preparation etc..Patent (CN1745633) report imazethapyr and bentazone and
Diphenyl ether herbicide compounds, and (CN102686109A) report imazethapyr compounds with fluroxypyr,
(CN104304274A) report imazethapyr compounds with cloransulammethyl.By glyphosate and imidazoles second cigarette
Acid is compounding, can improve the preparation drug effect to glyphosate-resistant weeds, extends the Life Cycle of glyphosate products
Phase.
Summary of the invention
Present invention aim at the complex weedicide providing a kind of glyphosate with imazethapyr.
For achieving the above object, the present invention uses the technical scheme to be:
A kind of glyphosate and the complex weedicide of imazethapyr, herbicide is with glyphosate-class herbicides and imidazoles
Second nicotinic acid is active component, glyphosate-class herbicides (in terms of glyphosate) and the mass parts of imazethapyr
Number ratio is 10-15:1.
The mass fraction ratio of described glyphosate-class herbicides (counting with glyphosate) and imazethapyr is as 14:1.
Described herbicide is soluble granula, by weight percentage, herbicide active active ingredients 5～90%, alkali
0.1～10%, surfactant 1～20% and water-solubility carrier 5～90%.
Described herbicide active active ingredients weight percentage is 10～70%.
Described glyphosate-class herbicides is glyphosate and/or glyphosate salt；Described glyphosate salt is glyphosate salt
One or more in ammonium salt, isopropyl amine salt, potassium salt, sodium salt, dimethylamine salt.
Described alkali is selected from sodium hydroxide, potassium hydroxide or triethanolamine.
Described surfactant selected from APG, tallow amine polyoxyethylene ether, castor oil polyoxyethylene ether,
Fatty alcohol-polyoxyethylene ether, dodecylbenzene sodium sulfonate, sodium lauryl sulphate, fatty alcohol-polyoxyethylene ether
One or more combinations in sodium sulfate, aliphatic alcohol polyoxyvinethene phosphate.
One or more in ammonium sulfate, anhydrous sodium sulfate, glucose, sucrose of described water-solubility carrier
Combination.
Described herbicide is as resistance glyphosate genetically modified crops herbicide formulations.
The application of herbicide, described herbicide is used for preventing and kill off resistance glyphosate genetically modified crops field weed, described miscellaneous
Grass is annual gramineous weed, perennial weeds and broad leaved weed.
Advantage for present invention:
Herbicidal composition of the present invention improves control of weeds effect, expands weed control spectrum.Glyphosate
Annual gramineous weed and part broad leaved weed preventive effect are highlighted by class herbicides compounds, but to perennial weeds
Poor with part broad leaved weed preventive effect.Use and glyphosate is compounded with imazethapyr, improve broad-leaved miscellaneous
Grass and the preventive effect of part malignant weed of tolerance glyphosate, therefore this complex weedicide combine glyphosate with
The activity of weeding of both imazethapyrs, and for relatively glyphosate and imazethapyr single dose, decrease agriculture
Medicine usage amount, reduces use cost, it is simple to popularization and application.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described, but does not limit the invention to
