Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of paddy rice Emulsionable herbicides preparation.
Background technology
AC322140 belongs to sulfonylurea, and sterling is gray solid；Fusing point 160.9 ~ 162.9 DEG C；Density 0.64 (20 DEG C)；Vapour pressure is 2.2 × 10-5Pa (20 DEG C).Distribution coefficient LogP (20 DEG C)=3.36 (pH 3), 2.045 (pH 5), 1.69 (pH 6), 1.41 (pH 7), 0.7 (pH 8)；In water, solubility (ppm) is: 0.17 (pH 5), 6.52 (pH 7), 549 (pH 9)；At room temperature deposit 18 months and stablize, deposit 12 months for 36 DEG C and stablize, deposit 3 months for 45 DEG C and stablize；In water the half-life (my god): 2.2 (pH3), 2.2 (pH 5), 5.1 (pH 6), 40 (pH 7), 91 (pH 8)；p K a 5.04.AC322140 is the inhibitor of acetolactate synthestase (ALS) as other sulfonylurea herbicide.Cyclammonium sulphur is grand can be absorbed by weeds root and leaf, conducts in plant body, and weeds i.e. stop growing, leaf look chlorisis, the most withered after general several weeks.AC322140 is mainly used in preventing and kill off annual and perennial broadleaf weed and sedge weed.Paddy field: perennial weeds such as water Rhizoma Sparganii, ovum fringe water chestnut, wild water chestnut, short arrowhead, firefly Lin；Grass, Monochoria vaginalis, mexicana and Vandellia weeds etc. on annual grassy weeds such as difformed galingale herb, chickweed, footpath between fields.
Imazamox is imidazolone type, and sterling is tasteless solid；Fusing point 166 ~ 166.7 DEG C；Vapour pressure is 1.3 × 10-5Pa (25 DEG C).Distribution coefficient LogP=5.36；In acetone, solubility is 2.93g/100ml.Imazamox is the same with other imidazolinone herbicide, mainly acetolactate synthestase (ALS) or the inhibitor of acetic acid hydroxy acid synzyme (AHAs), i.e. by suppressing the acetolactate synthestase of plant, stop the biosynthesis of branched-chain amino acid such as valine, leucine, isoleucine, the final synthesis destroying protein, interference D N A synthesis and cell division and growth.Most of grassy weed and broad leaved weed can be prevented and kill off.Broad leaved weed such as piemarker, acalypha copperleaf, field mustard, lamb's-quarters, bur beggar-ticks, clearvers, morning glory, benbie, field forget-me-not, knotweed, black nightshade, Veronica etc.；Grassy weed and sedge weed such as wild oat, bromegrass, annual bluegrass, moleplant seed, millet, amur foxtail, thin and delicate lady's-grass, rush, Chufa etc..
Current paddy rice herbicide, herbicidal effect is the best, and the property of medicine is held time short, and, big to rice hazard.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of paddy rice Emulsionable herbicides preparation.In herbicide of the present invention, effective active composition AC322140, the mutual mixture of imazamox will not produce conflict；Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weeds, the most effectively kill the weeds after being unearthed, it is possible to control not to be unearthed weeds, improves herbicidal effect；Active ingredient in herbicide of the present invention coordinates good synergistic effect within the specific limits, and preventive effect is higher than single dose, and the property of medicine is held time length；To rice safety.
A kind of paddy rice of the present invention is to be realized by following technical scheme with Emulsionable herbicides preparation: the active ingredient of described herbicide includes: AC322140, imazamox, AC322140 in herbicide, imazamox account for 45-80 part of herbicide gross mass, also include emulsifying agent 3-20 part, solvent 20-55 part.
Described AC322140, the part by weight of imazamox are 1-10:1-10.
AC322140, the part by weight of imazamox are 4:5.
AC322140, imazamox are dissolved in a solvent, adds emulsifying agent, be uniformly mixed the cream preparation i.e. preparing this herbicide.
Described emulsifying agent is calcium dodecyl benzene sulfonate and at least one in aliphatic acid polyethenoxy ether, APES sulfosuccinate, styrylphenol polyoxyethylene ether, NPE, castor oil polyoxyethylene ether, aliphatic acid polyethenoxy base ester, polyoxyethylene aliphatic alcohol ether.
Described solvent is at least one in dimethylbenzene, toluene, decyl amide, diesel oil, methyl alcohol, turpentine oil, ethanol, n-butanol, isopropanol, turpentine oil, solvent naphtha, dimethylformamide, dimethyl sulfoxide (DMSO).
Preferably, containing AC322140 32 parts by weight, imazamox 40 parts, aliphatic acid polyethenoxy ether 15 parts, dimethyl sulfoxide (DMSO) 45 parts in herbicide.
The dosage of this cream preparation is 300-600 gram of active ingredient/hectare.
Beneficial effects of the present invention:
In herbicide the most of the present invention, effective active composition AC322140, the mutual mixture of imazamox will not produce conflict；
2. broad weed-killing spectrum, can prevent and kill off most of annual and perennial weeds, the most effectively kill the weeds after being unearthed, it is possible to control not to be unearthed weeds, improves herbicidal effect；
Active ingredient in herbicide the most of the present invention coordinates good synergistic effect within the specific limits, and preventive effect is higher than single dose, and the property of medicine is held time length；
4. pair rice safety, has no adverse effects to underground water and environment.
