Summary of the invention
Technical problem to be solved by this invention is to provide a kind of compound herbicide, to enlarge the careless spectrum of killing of weed killer herbicide, raising herbicidal effect.
The present invention is achieved in that a kind of compound herbicide, and described weed killer herbicide contains any one in any one and the former medicine of sulfonylurea herbicide in the former medicine of benzene oxygen class weed killer herbicide, percentage meter by weight, and its proportioning is:
The former medicine 10.0-56.0% of benzene oxygen class weed killer herbicide
The former medicine 1.0-30.0% of sulfonylurea herbicide
Auxiliary agent 14.0-89.0%
The present invention's compound herbicide, combine the advantage of benzene oxygen class weed killer herbicide, carbamide herbicides, have the characteristics of inner sucting conduction type weed killer herbicide and hormone herbicide concurrently, have collaborative and synergistic effect, enlarged and killed the grass spectrum, improved herbicidal effect, remedied the defective of single agent the anti-heterodyne of main weeds, lasting period is long, and a drug can ensure that whole growing is not endangered by weeds.
Embodiment
Further specify the present invention below.
The former medicine of described benzene oxygen class weed killer herbicide is a kind of in mcpa sodium, methoxone amine salt, the different monooctyl ester of methoxone, methoxone sylvite, the methoxone phenoxy acetic acid, and the former medicine of described sulfonylurea herbicide is a kind of in nicosulfuron, chlortoluron, primisulfuronmethyl, rimsulfuron 25, the lorox.
The former medicine of described benzene oxygen class weed killer herbicide is mcpa sodium or methoxone amine salt, and the former medicine of described sulfonylurea herbicide is a nicosulfuron, and described auxiliary agent is surfactant and filler, percentage meter by weight, and its proportioning is:
Mcpa sodium or methoxone amine salt 10.0-56.0%
Nicosulfuron 1.0-30.0%
Surfactant 8.0-15.0%
Filler 6.0-74.0%
Described surfactant is the 2012# emulsifier, and described filler is white carbon or diatomite or attapulgite.Also can be kaolin.Surfactant also can be 2014#, 2015# emulsifier.
Preparation method of the present invention is, with mcpa sodium or methoxone amine salt and nicosulfuron oven dry, surfactant (2012# emulsifier) with white carbon or diatomite or attapulgite absorption, is pulverized behind the mixing, chemically examined and be distributed into wetting powder after qualified.Also can after chemical examination be qualified, add water and stir, make material, oven dry back packing, make granule.
The formulation of described weed killer herbicide is a kind of in wetting powder, granule, soluble powder, dry suspending agent, the water dispersible granules.Obviously, can select different auxiliary agents and filler for use according to the difference of formulation.
Methoxone (MCPA) sodium salt, methoxone amine salt are phenoxy acetic acid class selectivity hormone herbicide.It can pass cuticula and cytoplasma membrane, can be transmitted to each position of ruderal plant rapidly, influences the synthetic of nucleic acid and protein.After being transmitted to growing point it is stopped growing, carry out thereby suppress photosynthetic; Be transmitted to stem and can promote stem's abnormal cell division, rhizome expands, the forfeiture absorbing capacity, and cambium expands agglomerating obstruction screen casing, and organic nutrition is hindered to cause weeds death, so broad leaved weed is very responsive to it.The gramineous plants seedling phase is very sensitive to it, and 3～4 leaf after date pesticide resistance strengthen gradually, and late tillering state is the strongest, rises again to panicle spike primordium differentiation stage susceptibility.So should be in crop late tillering state dispenser.Mcpa sodium, methoxone amine salt volatility are low, and speed of action is slow, use coldly safer.
Nicosulfuron (nicosulfuron) is the inner sucting conduction type weed killer herbicide, can absorb and conduction rapidly by stem leaves of plants and root, the activity that suppresses acetate lactic acid synzyme in the plant corpus, stop branched chain group acid synthetic and then prevention cell division, sensitive plant is stopped growing as valine, leucine and isoleucine.Nicosulfuron is applicable to corn, and sweet corn is to the nicosulfuron sensitivity.To noresidue poisoning such as back stubble wheat, garlic, sunflower, clover, potato, soybean.Can prevent and kill off annual and perennial broadleaf weed, lamb's-quarters, little lamb's-quarters, summer cypress, reed etc. are had drug effect preferably.Nicosulfuron not only has the activity of cauline leaf processing preferably but also has closed soil to kill the grass effect, so dispenser should not be late excessively.
The pure product of methoxone are colourless, tasteless crystallization, are slightly soluble in water, and 25 ℃ of solvability 825ml/L are soluble in ethanol, acetone and other organic solvent, can generate corresponding salt with various bases, are made generally in sodium salt.The former powder of mcpa sodium is a brown powder, and the penetrating odor of phenol is arranged.Soluble in water, dry powder is moisture absorption caking very easily, but never degenerates.The activity of weeding of mcpa sodium, methoxone amine salt is identical with methoxone.
The pure product of nicosulfuron are clear crystal, and are not soluble in water, and the solvability in the time of 25 ℃ in water is 120ml/L.
The present invention's compound herbicide has the synthetic of synthetic, the interferencing protein that suppresses enzyme in the weeds concurrently and hinders the various active of the normal activity of hormone in the weeds, has improved herbicidal effect, and it is active to have stem, leaf action of contace poison and an interior suction conduction.And, have certain closed soil effect, the weeds of not being unearthed there is certain activity.The present invention is by killing the grass spectrum with mcpa sodium or methoxone amine salt and composite also expansion of nicosulfuron, broad weed-killing spectrum, can effectively prevent and kill off the annual and perennial difficulty of part of corn field cuts weeds, comprise grass family and broad-leaved section weeds such as amur foxtail, wild oat, barnyard grass grass, lady's-grass, eleusine indica, the rhizome of nutgrass flatsedge, kitchen garden, Amaranthus retroflexus, field bindweed, lamb's-quarters, convexutricle sedge herb, Monochoria vaginalis, wartwort, angustifolia arrowhead herb etc., played the wealthy two effects of removing of standing grain.
The using method of the present invention's compound herbicide is: corn field is made cauline leaf and is handled.In the corn 3-4 leaf phase, dispenser when weeds are unearthed and reach 5cm left and right sides plant height.During dispenser, can earlier its water be made into mother liquor.Be about 25ml by mcpa sodium or every mu of effective ingredient of methoxone amine salt, every mu of effective ingredient of nicosulfuron is about the requirement of 1.4ml, determines dosage.Fill up the water yield again after mother liquor shaken up, carry out the field even spraying and handle.As when adopting the granule formulation, with low amounts of water particle is fully dissolved earlier, fill up the water yield again, carry out the field even spraying and handle.
