Description
Technical field
The invention belongs to pesticide herbicide technical field, particularly the Herbicidal combinations for preventing and kill off rice direct-seeding field weed of pyrazosulfuron, fenoxaprop, penoxsuam composition.
Background technology
Paddy rice is one of staple food crop of China, and rice is the staple food of the whole nation about 60% population, and its sowing area accounts for 18.5% of the total sowing area in the whole nation, and rice yield accounts for 39.23% of total grain output, the impact that therefore the increase and decrease tool of the output of paddy rice is very important.But all the time, all kinds of weeds have impact on the output of paddy rice, according to investigations, its Rice Yield Loss Caused of the field of weed encroachment generally at 10-20%, serious loss 40-50%.In recent years, the planting patterns direct seading rice of a kind of saving of labor, water saving rises rapidly, its management of weeds more seems and is even more important, wherein affect more greatly and more difficult anti-be the grassy weed such as barnyard grass, moleplant seed, be secondly the broad leaved weeds such as Monochoria vaginalis, mexicana, potamogeton grass.Herbicide for paddy field development is more delayed, and kind is few, and the wider of application is bensulfuron-methyl, Acetochlor, methoxone etc., but due to these service life of the products longer, weeds create drug resistance, and they are unsatisfactory to the effect of barnyard grass, moleplant seed.
The chemical name of pyrazosulfuron is 5-(4,6-dimethoxypyridin base-2-carbamoylamino sulphur-1-methylpyrazole-4-carboxylic acid (ethyl ester), belong to sulfonylurea herbicide, for selectivity inner-adsorption conduction-type herbicide, absorbed mainly through root system, shift rapidly in weeds plant body, Developing restraint, weeds are dead gradually.Paddy rice can decompose this medicament, does not almost affect paddy growth, and efficacy stability, safety is high, the lasting period is long, reaches 25-35 days.
Fenoxaprop belongs to heterocyclic oxy group phenoxy propionic acid class weed killer herbicide, mainly by suppressing key enzyme one acetyl-CoA carboxylase of fatty acid synthesis, thus inhibits the synthesis of fatty acid.Medicament is by cauline leaf Assimilation and conductivity to the growing point of meristematic tissue and root, and effect rapidly, stops growing for after dispenser 2-3 days, 5-6 days lobus cardiacus chlorosis purpling looks, meristematic tissue browning look, and blade is withered gradually, is the extremely strong cauline leaf inorganic agent of selectivity.
Penoxsuam is rice field broad-spectrum herbicide, effectively can prevent and kill off barnyard grass (comprising the barnyard grass to Stam F-34, dichloro quinolinic acid and anti-acetyl-CoA carboxylase tool resistance), annual sedge weed, and it is effective to numerous broad leaved weed, lasting period reaches 30 ~ 60 days, a drug energy basic controlling full season Weed infestation.Meanwhile, it also can prevent and kill off anti-bensulfuron-methyl weeds in rice field, and has residual activity to many broad-leaveds and sedge weed and barnyard grass etc., but it is invalid to moleplant seed weeds, as needed control, can be mixed with cyhalofop-butyl, be the kind that herbicide spectrum in current herbicide for rice field is the widest.
Summary of the invention
The object of the invention is just to be to provide a kind of synergistic effect significantly, the rice direct seeding field ternary weeding composition of broad weed-killing spectrum.
Of the present inventionly following scheme is taked to realize:
A kind of Herbicidal combinations for rice direct seeding field, this Herbicidal combinations comprises pyrazosulfuron, fenoxaprop, penoxsuam and synergist, and the mass ratio of described pyrazosulfuron, fenoxaprop, penoxsuam and synergist is 1 ~ 50: 1 ~ 15: 10 ~ 20:1 ~ 5.
Further, described synergist is organosilicon, cyclohexanedione or pyrrolidones.
Further, described Herbicidal combinations also contains agriculturally acceptable surfactant and carrier.
Further, the formulation of described Herbicidal combinations is wetting powder, suspending agent or water-dispersible granules.
In Herbicidal combinations of the present invention, active component is pyrazosulfuron, fenoxaprop, penoxsuam; and with the addition of synergist; its consumption to depend on when being used alone respective amount of application and three's portfolio ratio and synergy degree; the mass ratio of special protection of the present invention pyrazosulfuron, fenoxaprop, penoxsuam and synergist is 1 ~ 20: 5 ~ 25: 5 ~ 45: 1 ~ 5, and best proportioning is 8:4:10:3.
Organosilicon refers to containing Si-O key, and has at least an organic group to be the compound be directly connected with silicon atom.Organosilicon has unique structure: C-H is nonpolarity, makes intermolecular interaction very faint; Si-O bond distance is longer, and Si-O-Si key bond angle is large; Si-O key is the covalent bond (covalent bond has directionality, and ionic bond is non-directional) with 50% ionic bond feature.Due to the structure of organosilicon uniqueness, have both the performance of inorganic material and organic material, have that surface tension is low, viscosity-temperature coefficient is little, agricultural chemicals can be impelled to soak rapidly, penetrate into the surface of plant, make the effect of agricultural chemicals perform to maximum effectiveness, and extend the action time of medicament.
Cyclohexanedione, pyrrolidones and silicone based like being all act on the synergist on weed killer herbicide, obviously can improve wetting, the spread of pyrazosulfuron, Evil humulone and pendimethalin, dispersion, delay and permeance property, reduce spray liquor (air-flow) drift with the wind, prevent or alleviate the infringement to contiguous sensitive crop etc., be beneficial to liquid blade face sprawl and stick, reduce ultraviolet to pesticidal preparations in the decomposition of active ingredient, reach and extend the drug effect term of validity, improve its biologically active; And system or the anti-poisoning effect of the reduction removing toxic substances of target weeds to pesticide activity, delay the accretion rate of medicament in controlling object, thus increase biological preventive effect.
Herbicidal combinations of the present invention, can add agriculturally acceptable surfactant and carrier, be made into wetting powder, suspending agent or microemulsion etc.Wherein surfactant is alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, phenethyl phenol polyethenoxy ether, phenethyl phenol polyethenoxy polyethenoxy ether, castor oil ethylene oxide adduct, alkylphenol polyoxyethylene formaldehyde condensation products, alkylphenol polyoxyethylene phosphate, phenethyl phenol polyethenoxy ether phosphate, Ben-zylphenol Polyoxyethyl Ether, polyoxyethylene carboxylate, calcium dodecyl benzene sulfonate, neopelex, lignosulfonates, NNO, NO, MF, ZS-1, lauryl sodium sulfate, pull open powder, N-Methyl fatty acyl taurines sodium, alkylphenol polyoxyethylene formaldehyde condensation products sulphate, the withered powder of tea, saponin, lignosulfite, aliphatic alcohol sulfate, penetrant t, bleeding agent OT, JFC, fatty acid amide-N-N-methyltaurine sodium salt, sodium sulfate of polyethenoxy ether of fatty alcohol, pull open powder etc.
Carrier is divided into solid carrier and solvent, and solid carrier has bentonite, White Carbon black, kaolin, precipitated calcium carbonate, sodium sulphate, ammonium sulfate, diatomite, starch, potter's clay etc.; Solvent has toluene, dimethylbenzene, chlorobenzene, solvent naphtha, α-methyl naphthalene, turpentine oil, carrene, chloroform, methyl alcohol, ethanol, glycerine, ethylene glycol, butanols, isoamyl alcohol, propane diols, cyclohexanone, isophorone, acetophenone, ethyl acetate, propyl acetate, butyl acetate, DMF, DMSO, cellosolve etc., above-mentionedly to can be used alone, also can more than two kinds compound uses.
Various auxiliary agent or carrier all can commercially have been bought above.
The Herbicidal combinations of rice direct seeding field of the present invention has addition or synergistic effect, within after being mainly used in rice direct seeding field transfer about 10 days, spray, prevent and kill off the grassy weeds such as rice direct seeding field barnyard grass prevailing, moleplant seed, broad leaved weed and the sedge weeds such as needle spikesedge herb, difformed galingale herb such as other mexicana anti-of also holding concurrently, duck tongue, wartwort grass.Have that activity of weeding is high, broad weed-killing spectrum, feature easy to use, and to rice safety, belong to environmentally friendly weed killer herbicide.
