Abstract
The invention relates to a water dispersible granule of a herbicide. The water dispersible granule has the beneficial effects the active ingredients including amidosulfuron and pyraflufen-ethyl in the herbicide do not collide with each other when being mixed with each other; the herbicide has a wide weed control spectrum; through cooperation of the active ingredients in the herbicide, the herbicide has good synergistic effects in a certain range, has better control effects than a single agent and has long property duration; the herbicide is safe to crops.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, be specifically related to a kind of herbicide water dispersible granule.
Background technology
Amidosulfuron
belong to sulfonylurea, 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.
Pyrrole grass ether
for pyrazoles, sterling is brown solid; Fusing point 126 ~ 127 DEG C; Vapour pressure is 4.79 × 10-3Pa (25 DEG C).In water, solvability is <1ppm (25 DEG C).Solvability (25 DEG C, % weight) in other solvent: dimethylbenzene 2.9, acetone 25.0, ethanol 1.0, ethyl acetate 14.5.Rat acute per os L D50:>5000mg/kg; This product to lagophthalmos eyeball and rabbit skin non-stimulated.Ichthyotoxin L C50 (when 48 little 295): carp and rainbow trout >10ppm.A m e s test is negative.Without mutagenicity.
The existing agricultural chemicals for cereal crop, selectivity is not strong, and have impact to succession crop, herbicidal effect is good not.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of herbicide water dispersible granule.In weed killer herbicide of the present invention, effective active composition amidosulfuron, the mutual mixture of pyrrole grass ether can not produce conflict; Broad weed-killing spectrum; 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 crop safety.
A kind of herbicide water dispersible granule of the present invention is realized by following technical scheme: the active ingredient of described weed killer herbicide comprises: amidosulfuron, pyrrole grass ether.Wherein, active ingredient accounts for 40-80 part of weed killer herbicide gross mass, also comprises dispersant 3-20 part, wetting agent 3-10 part, disintegrant 2-5 part, filler 1-70 part.
The part by weight of described amidosulfuron, pyrrole grass ether is 1-10:1-10.
Further, the part by weight of amidosulfuron, pyrrole grass ether is 3-5:1.
Preferably, the part by weight of amidosulfuron, pyrrole grass ether is 3.6:1.
By formula, amidosulfuron, pyrrole grass ether and dispersant, wetting agent, disintegrant and filler are mixed, pulverize with micro jet, through mediating, then adding in fluidized-bed granulation dryer and carrying out granulation, drying, screening, obtained herbicide water dispersible granule.
Described dispersant is: fatty acid glyceride APEO.
Described wetting agent is: lauryl sodium sulfate.
Described disintegrant is: citric acid.
Described filler is: bentonite.
This herbicide water dispersible granule is used for the early stage postemergence weed control of cereal crop.
Beneficial effect of the present invention:
In weed killer herbicide of the present invention, effective active composition amidosulfuron, the mutual mixture of pyrrole grass ether can not produce conflict; Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weed, especially to broad leaved weeds successful, not only effectively kills the weeds after being unearthed, also can control weeds of not being unearthed, improve 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 when stubble and after stubble cereal crop safety, such as wheat, corn, Chinese sorghum etc.The water dispersible granules of weed killer herbicide of the present invention is easy to use, good stability, to crop safety.
