Abstract
The invention discloses a nicosulfuron herbicide. The nicosulfuron herbicide comprises, by weight, 8 to 18% of nicosulfuron, 2 to 10% of a wetting agent, 2 to 10% of a dispersant, 0.5 to 6% of a thickening agent, 0.1 to 1% of an antifoaming agent, and the balance oil; the thickening agent is a mixture of organic modified bentonite with a modified magnesium aluminum hydrotalcite, and the modified magnesium aluminum hydrotalcite is dodecyl sulfonate intercalated magnesium aluminum hydrotalcite. The nicosulfuron herbicide is high in suspension stability, is capable of satisfying requirements in high altitude cold regions, and is excellent in drug effect.
Description
Technical field
The invention belongs to herbicide technology field and in particular to a kind of nicosulfuron oil suspension herbicide.
Background technology
Nicosulfuron (nicosulfuron), other titles：Beautiful agriculture is happy, cigarette sulphur is grand, sulfonylurea herbicide, chemical name
Claim：2- (4,6- dimethoxypyridin -2- base carbamoylamino sulphonyl)-N, N- dimethyl nicotinamide.Nicosulfuron is interior suction
Property, high efficiency corn herbicide, with can effectively prevent and kill off multiple annual gramineous weeds in corn field after low dosage bud, broad-leaved is miscellaneous
Grass and sedge weed.It is absorbed rapidly by leaf and root, and is conducted rapidly by xylem and bast, is closed by acetolactic acid
Enzyme is become to stop the synthesis of branched-chain amino acid.After applying nicosulfuron, weeds stop growing immediately, and 4～5 days young leaves fade, bad
Extremely, and progressively expand to whole plant, plant death in 20～25 days after processing under general condition.This medicine not only has cauline leaf process
Effect, also has activity of weeding before bud.Corn has preferable drug resistance to this medicine, temporary transient chlorisis or slight sending out after process
It is slow to educate, but typically can recover rapidly and the not underproduction.
It is the dispersion in oil insoluble in oily solid pesticide or immiscible liquids agricultural chemicals that pesticide oil suspension floats agent, from production
Angle considers, typically requires active compound to be solid at room temperature, and the solubility (20 DEG C～40 DEG C) in decentralized medium is less than
The pesticide species of 100mg/L.The advantage that pesticide oil suspension floats agent is uniformly can to mix dispersion with oil with arbitrary proportion, easy to use,
It is difficult to pollute environment, can directly or after dilution spray.Preparation for processing can make high dispersive, continuous phase by wet pulverizing
Suspension, the average grain diameter of its particle, typically below 3 microns, substantially increases suspensibility in aqueous medium for the particle, strengthens
Absorptions to medicament for the crops.Existing nicosulfuron oil-suspending agent based on soybean oil, such as Chinese patent application
201510170203X proposes a kind of soybean oil systems and dispersibles oil-suspending agent auxiliary agent and dispersible oil-suspending agent, this suspending agent
In actual use there is problems that, the Northeast's temperature is relatively low, and suspending agent keeps the emulsion state time short thereat,
Easily form flocculation, lead to drug effect to play and have a greatly reduced quality.
Content of the invention
The present invention proposes a kind of nicosulfuron herbicide agent, and not only suspension stability is high for this herbicide, meets High aititude low temperature
The needs in area, and good drug efficacy.
The technical scheme is that and be achieved in that：
A kind of nicosulfuron herbicide agent, calculates according to percetage by weight, including：
Nicosulfuron 8～18%, wetting agent 2～10%, dispersant 2～10%, thickener 0.5～6%, defoamer 0.1
～1%, balance of oil；Described thickener is the mixture of organic modified bentonite and modified magnalium hydrotalcite composition, described changes
Property magnalium hydrotalcite be dodecyl sodium sulfonate intercalation magnesia-alumina hydrotalcite.
Further, described organic modified bentonite and the mass ratio of modified magnalium hydrotalcite are 3～5:1.
Further, described organic modified bentonite changes to sodium bentonite for dodecyl benzyl dimethyl ammonium chloride
Property obtains.
Further, described wetting agent is fatty alcohol polyglycol ether sulfate, AEO or alkylnaphthalene
Sulfonic formaldehyde condensation compound.
Further, described dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, sodium methylene bis-naphthalene sulfonate or gathers
Vinylpyrrolidone.
Further, described defoamer is dimethicone or silicone.
Further, described oil is soybean oil, rape seed oil, peanut oil or epoxidized soybean oil
The preparation method of nicosulfuron of the present invention：
1) nicosulfuron active compound, wetting agent, dispersant, defoamer and oil are added into mixing kettle, under high shear stirring,
So that material is sufficiently mixed uniformly, obtain mixture A；
2) and then by mixture A it is heated to 40～60 DEG C, add organic modified bentonite and modified magnalium hydrotalcite, constantly
Stirring, after being cooled to room temperature, mixed material is squeezed in sand mill and grinds, sand milling 2～3h, you can.
Beneficial effects of the present invention：
1st, the thickener of the present invention is organic modified bentonite and dodecyl sodium sulfonate intercalation magnesia-alumina hydrotalcite forms
Mixture, organic modified bentonite can not only thickening, help stability and suspending buoyancy, and by bentonite
Modification enhances its hydrophily, is conducive to the performance of nicosulfuron drug effect.Dodecyl sodium sulfonate intercalation magnesia-alumina hydrotalcite possesses
Stronger hydrophobicity, after it is mixed with organic modified bentonite, improves its thixotropic property, enhances electrostatic attraction effect and is formed
Space net structure, improve the stability in low temperature for the suspending agent.
2nd, the nicosulfuron herbicide agent of the present invention is opening up good penetrability as object plane when using, and decreases active ingredient stream
Lose, have notable synergistic to act on.
