Abstract
The invention relates to a herbicide suspending agent containing pentoxazone and amidosulfuron. According to the herbicide disclosed by the invention, effective active ingredients, namely pentoxazone and amidosulfuron, are mixed with each other, so that the herbicide controlling spectrum is broad; the effective ingredients of the herbicide disclosed by the invention have a very good synergistic effect when the effective ingredients are matched in a certain range, the control effect is higher than that of single preparations, and the medicine property duration is long; the herbicide is extremely safe to cereal crops.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of weed killer herbicide suspending agent containing pentoxazone and amidosulfuron.
Background technology
Pentoxazone, chemical name 3-(the chloro-5-cyclopentyloxy of 4--2-fluorophenyl)-5-isopropyl alkene-1,3-oxazoles quinoline-2,4-diketone, structural formula
, belong to oxazoline ketone, sterling is colourless, tasteless powdery solid; Fusing point 104 DEG C; Density 1.418 (25 DEG C); Vapour pressure is <1.11 × 10-5Pa (25 DEG C).Distribution coefficient LogP=0.67; In water, solvability is 0.216 mg/l (25 DEG C); To light, heat, absolute acid stability, unstable to alkali.Be mainly used in preventing and kill off barnyard grass and annual weed etc.Take p-fluorophenol as initiation material, through the nitrobenzene that chlorination, esterification, nitrated obtained intermediate replace; Through being hydrolyzed the phenol sylvite that obtained intermediate replaces; Again through etherificate, the aniline making replacement that reduces; After last and ethyl chloroformate reacts, namely obtain object with senecioic acid ester condensation.
Amidosulfuron chemical name is 1-(4,6-dimethoxypyridin-2-base)-3-mesyl (methyl) aminosulfonyl urea, and structural formula is
, 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.Be mainly used in preventing and kill off broad leaved weed, effective especially to clearvers etc.
Above two kinds of medicines, after long-term being used alone, all easily making plant germ develop immunity to drugs, cause the problems such as dosage increasing, preventive effect reduction, lasting period shortening, be unfavorable for environment sustainable development.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of weed killer herbicide suspending agent containing pentoxazone and amidosulfuron.Effective active composition pentoxazone, the mutual mixture broad weed-killing spectrum of amidosulfuron in weed killer herbicide of the present invention; 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; Extremely safe to cereal crop.
A kind of weed killer herbicide suspending agent containing pentoxazone and amidosulfuron of the present invention is realized by following technical scheme: the active ingredient of described weed killer herbicide comprises: pentoxazone, amidosulfuron.Wherein, pentoxazone, prosulfuron account for 25-50 part of weed killer herbicide gross mass, also comprise dispersant 5-20 part by weight, antifreezing agent 1-5 part, thickener 1-2 part, defoamer 0.5-1 part, water 50-80 part.
Described pentoxazone, the part by weight of amidosulfuron are 1-20:1-20.
Further, the part by weight of pentoxazone, amidosulfuron is 10-20:3.
Preferably, the part by weight of pentoxazone, amidosulfuron is 20:3.
First mixed by other auxiliary agents, mix through high speed shear, add pentoxazone, pyrrole grass ether, abrading-ball 2-3 hour in ball crusher, makes a diameter all at below 5mm, the suspending agent of this weed killer herbicide obtained.
Described dispersant is lignosulfonates.
Described antifreeze glycol.
Described thickener xanthans.
Described defoamer is silicone oil.
This weed killer herbicide suspending agent is for weeding before cereal crop seedling.
Beneficial effect of the present invention:
In weed killer herbicide of the present invention, effective active composition pentoxazone, the mutual mixture of amidosulfuron can not produce conflict; Broad weed-killing spectrum, effectively can improve herbicidal effect relative to single-activity composition; 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, decreases agricultural chemicals Reusability number of times, reduces Pesticide use amount, reduce the use cost of agricultural chemicals; Extremely safe to cereal crop.Suspensions stability of the present invention is good, easy to use, good dispersion, and the ability sticking to plant surface is stronger, resistance of rainwater washing against, lasting medicine, and penetration is strong, and cost is low, and drug effect is high.
