Abstract
The invention relates to a herbicide and particularly discloses a weeding composite with nicosulfuron and quinclorac. The active ingredient of the weeding composite is the mixture of nicosulfuron and quinclorac, wherein the ratio of the weight percentage of nicosulfuron to the weight percentage of quinclorac is 1-20%:40-1%. The weeding composite has wide herbicidal spectrum, good herbicidal effect on elder gramineous weeds, remarkable synergistic effect, low combination dosage and lower cost and environmental pollution.
Description
(1) technical field
The present invention relates to a kind of weed killer herbicide, particularly a kind of Herbicidal combinations that contains nicosulfuron and dichloro quinolinic acid.
(2) background technology
Weeds are formidable enemies that crops produce, if it is not controlled, it is striven water and strives fertile characteristic and can bring heavy losses to crop.Corn is the staple food crop of China, nicosulfuron is one of main weed killer herbicide of corn field, can behind bud, effectively prevent and kill off multiple annual gramineae, broad leaved weed and sedge weed, it is by the leaf of plant and root absorbs and conduction rapidly, by suppressing the activity of acetolactate synthestase in the plant corpus, stop the synthetic of branched-chain amino acid and the prevention cell division.Use handle 4～5 days blades in back fade, downright bad and expand to whole plant very soon.The nicosulfuron high-efficiency broad spectrum, but a lot of shortcomings are also arranged,, not good such as low temperature to above the average age for marriage grassy weed to the grassy weed poor effect, to the responsive easily generation of a lot of serial corn varieties poisoning.
Dichloro quinolinic acid is interior absorption hormone herbicide, mainly absorbs by the weeds root, also can be absorbed by seeds germinated, and conduction makes weeds death in the weeds body, is mainly used to prevent and treat grassy weed.
(3) summary of the invention
The present invention provides the Herbicidal combinations that contains nicosulfuron and dichloro quinolinic acid that a kind of control efficiency is good, enlarge careless extremely spectrum in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of Herbicidal combinations that contains nicosulfuron and dichloro quinolinic acid, it is characterized in that: its active component is the mixture of nicosulfuron and dichloro quinolinic acid, the weight fraction ratio of nicosulfuron and dichloro quinolinic acid is 1～20%: 40～1%, preferred proportioning is 3～8%: 20～2%, and best proportioning is 3～6%: 20～10%.
Described dichloro quinolinic acid comprises dichloro quinolinic acid, dichloroquinoline acid sodium-salt, dichloro quinolinic acid methylamine salt, dichloro quinolinic acid ethylamine salt, dichloro quinolinic acid ethanolamine salt and dichloro quinolinic acid isopropyl amine salt.
Its active component accounts for 0.5～90% of composition weight, and preferred weight fraction is 0.5～50%.
Described composition is missible oil, wetting powder, granula, water dispersible granules, aqueous suspension agent, aqueous emulsion, dry suspending agent, microemulsion or oil-suspending agent.
Method of application of the present invention depends on specific application, in all cases, must guarantee that their dispersion is trickle as much as possible and even.
These preparations can prepare in a known manner, for example by active compound is mixed with solvent and carrier; If desired, can fill with emulsifier and dispersant; If water is cooked thinner, also can make cosolvent with other solvents.
The cosolvent that is fit to this purpose mainly is:
Solvent such as aromatic compound (as dimethylbenzene), chlorinated aromatic hydrocarbons compound (as chlorobenzene), paraffin (as petroleum distillate), alcohols (as methyl alcohol, ethanol), ketone (as cyclohexanone), amine (as monoethanolamine, dimethyl formamide) and water.
Carrier has the natural mineral matter (as kaolin, diatomite, calcite, talcum etc.) of grinding and the synthetic mineral matter (for example white carbon) that grinds.
Emulsifier has nonionic and anion emulsifier as (polyoxyethylene aliphatic alcohol ether, alkylsulfonate and arylsulphonate).
Dispersant has lignin sulfite waste liquor or methylcellulose.
Being fit to surface-active material is that aryl sulfonic acid is (as lignin sulfonic acid, phenolsulfonic acid, naphthalene sulfonic acids and dibutyl naphthalene sulfonic acids) and the alkali metal of fatty acid, alkaline earth metal and ammonium salt, alkylsulfonate and alkylaryl sulfonates, alkyl sulfate, lauryl ether sulfuric acid and aliphatic alcohol sulfate, and Sulfated 16-, 17-and the salt of octadecanol and fatty alcohol ether, the condensation product of gentle its derivative of sulfonated naphthalene and formaldehyde, the condensation product of naphthalene or naphthalene sulfonic acids and phenol and formaldehyde, dioxygen ethene octylphenol ether, the iso-octyl of ethoxylation-, octyl group or nonyl phenol, alkylphenol or tributyl phenyl polyglycol ether, different three decyl alcohol, the fatty alcohol ethylene oxide condensate, ethoxylated castor oil.Polyoxyethylene or polyoxypropylene alkyl ether, laruyl alcohol polyglycol ether acetic acid esters, sorbitan ester, lignin sulfite waste liquor or methylcellulose.
Moisture method of application can be by adding water, for example by missible oil, dispersion liquid, paste, wetting powder, effervescent tablet or water dispersion granule preparation.When preparation emulsion, paste, oily dispersion liquid or liquid water surface leafing agent, by adding the concentrate that wetting agent, adhesive, dispersant or emulsifier and possible solvent or oil are formed, this concentrate is fit to dilute with water.
Pulvis, spreading fertilizer over the fields pulvis, effervescent tablet, solid-state floater can be by mixing active substance or grinding and produce with solid matter.
Granule can prepare by reactive compound is adhered on the solid carrier.
Solid carrier is synthetic material such as white carbon, ammonium sulfate, ammonium phosphate, ammonium nitrate, urea and plant product such as flour, plant powder, sawdust, cellulose powder and other the solid powder carrier of ore soil as silica gel, silicic acid, silicate, talcum, kaolin, calcite, precipitated calcium carbonate, lime stone, diatomite, chalk, calcium sulphate, magnesium sulfate and grinding.
Application dosage of the present invention is generally 20～1000g a.i./ha according to different time, place, potential difference selectivity, weather conditions, preferred 50～300a.i./ha.Generally be foliage application, for example foliar spray is handled.
The present invention is applicable to annual gramineae hodgepodge and perennial broadleaf weeds such as directed spraying control barnyard grass grass, Ma Tang, lamb's-quarters, Amaranthus retroflexus, black nightshade, elscholtiza, piemarker, Commelina communis, bur beggar-ticks, eleusine indica, pale persicaria between corn full field spraying and other crop rows.
Broad weed-killing spectrum of the present invention, effective to above the average age for marriage grassy weed, synergistic effect is remarkable, and composite consumption is few, has reduced cost, has reduced environmental pollution.

From table 1 to table 4 as can be seen, the ratio of nicosulfuron is big more, and synergy is big more relatively.
As can be seen from Table 1, (nicosulfuron: dichloro quinolinic acid=8～5: 2～5), calculate with ED90 to barnyard grass grass synergy and summation action the back that is mixed, and the co-toxicity coefficient is 118-334 in measuring 4 mixed ratios of two kinds of weed killer herbicides.Table 2 pair eleusine indica, table 3 pair dayflower, table 4 pair kitchen garden be 5 interior (nicosulfurons: dichloro quinolinic acid=4～8: 2～6) synergy and summation action are arranged all of mixed ratio as can be seen.
As can be seen, calculate with ED90, nicosulfuron and dichloro quinolinic acid ratio are 6～8: synergistic effect in 2～4 o'clock is obvious.
Comprehensive virulence coefficient and cost factor, optimal proportion be nicosulfuron and dichloro quinolinic acid ratio 7～8: 2～3.
