Abstract
The invention belongs to the field of pesticides, and in particular relates to a special herbicide for wheat. Effective active components, namely, amidosulfuron and pyribenzoxim in the herbicide can be blended without contradiction, the herbicide controlling spectrum is wide, most annual and perennial weeds can be prevented and eliminated, not only are unearthed weeds effectively killed, but also earthed weeds can be controlled, and the weeding effect is improved; after being matched within a certain range, the effective components in the herbicide has a very good synergism effect, the prevention effect is higher than that of a single dosage, and the drug properties last for a long time; the herbicide is safe to in-season wheat and later crops.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a grow wheat herbicides special.
Background technology
Amidosulfuron belongs to sulfonylurea, and sterling is white granular solid; Fusing point 160 ~ 163 DEG C; Density 1.5 (20 DEG C); Vapour pressure is 2.2 × 10-5Pa (20 DEG C).Distribution coefficient LogP (20 DEG C)=1.63 (pH 2); Solvability (20 DEG C, mg/l) is: 3.3 (pH 3), 9 (pH 5.8), 13500 (pH 10) in water, isopropyl alcohol 99, methyl alcohol 872, acetone 8100; At room temperature deposit and stablize for 24 months; P K a 3.58.Amidosulfuron is the inhibitor of acetolactate synthestase (ALS).Absorbed by weeds root and leaf, conduct in plant body, namely weeds stop growing, leaf look chlorisis, then withered.With methylsulfonamides, dimethoxypyridin amine for initiation material, can obtain.
Pyribenzoxim is pyrimidine ether, and sterling is tasteless white solid; Fusing point 128 ~ 130 DEG C; Vapour pressure is <7.4 × 10-6Pa; Distribution coefficient LogP=3.04; Solvability in water: 3.5ppm.The inhibitor of acetolactate synthestase (ALS), capable of being fast degraded in soil, therefore on underground water without impact.To environment also safety.On lower stubble crop rotation also without impact.Numerous grassy weeds and broad leaved weed can be prevented and kill off.Grassy weed is as amur foxtail, lady's-grass, barnyard grass, green foxtail, annual bluegrass, Bermuda grass etc.; Broad leaved weed is as piemarker, ambatch, Amaranthus retroflexus, large bur beggar-ticks, Cassia tora, lamb's-quarters, field bindweed, clearvers, kitchen garden, sheep hoof, knotweed, sesbania, black nightshade, chickweed, dandelion, pansy, Noogoora burr.Especially good to barnyard grass activity.
Existing weeding for wheat agent herbicide spectrum is wide not, and herbicidal effect is poor, and the property of medicine is held time short.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a grow wheat herbicides special.In weed killer herbicide of the present invention, effective active composition amidosulfuron, the mutual mixture of pyribenzoxim can not produce conflict; Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weed, not only effectively kills the weeds after being unearthed, also can control weeds of not being unearthed, and improves herbicidal effect; Active ingredient in weed killer 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 working as stubble wheat and succession crop safety.
A grow wheat herbicides special of the present invention is realized by following technical scheme: the active ingredient of described weed killer herbicide comprises: amidosulfuron, pyribenzoxim.
Described amidosulfuron, the part by weight of pyribenzoxim are 1-10:1-10.
The part by weight of amidosulfuron, pyribenzoxim is 1:4.
Weed killer herbicide is missible oil.
Amidosulfuron in weed killer herbicide, pyribenzoxim account for 45-80 part of weed killer herbicide gross mass, also comprise emulsifier 3-20 part, solvent 20-55 part.
Amidosulfuron, pyribenzoxim are dissolved in a solvent, adds emulsifier, be uniformly mixed the cream preparation of i.e. this weed killer herbicide obtained.
Described emulsifier is at least one in calcium dodecyl benzene sulfonate and aliphatic acid polyethenoxy ether, alkylphenol polyoxyethylene sulfosuccinate, styrylphenol polyoxyethylene ether, polyoxyethylene nonylphenol ether, castor oil polyoxyethylene ether, aliphatic acid polyethenoxy base ester, polyoxyethylene aliphatic alcohol ether;
Described solvent is at least one in dimethylbenzene or biodiesel, toluene, decyl amide, diesel oil, methyl alcohol, turpentine oil, ethanol, n-butanol, isopropyl alcohol, turpentine oil, solvent naphtha, dimethyl formamide, dimethyl sulfoxide (DMSO), water.
Containing amidosulfuron 13 parts, pyribenzoxim 52 parts, aliphatic acid polyethenoxy ether 15 parts, dimethyl sulfoxide (DMSO) 45 parts by weight in weed killer herbicide.
Beneficial effect of the present invention:
1. in weed killer herbicide of the present invention, effective active composition amidosulfuron, the mutual mixture of pyribenzoxim can not produce conflict;
2. broad weed-killing spectrum, can prevent and kill off most of annual and perennial weed, not only effectively kills the weeds after being unearthed, also can control weeds of not being unearthed, and improves herbicidal effect;
3. active ingredient in weed killer 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;
4. pair when stubble wheat and succession crop safety.
