Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of herbicide suspending agent containing pentoxazone and prosulfuron.
Background technology
Pentoxazone, chemical name 3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl)-5-isopropyl alkene-1,3-oxazoles quinoline-2,4-diketone,
Structural formulaBelonging to oxazoline ketone, sterling is powder colourless, tasteless
Shape solid；Fusing point 104 DEG C；Density 1.418 (25 DEG C)；Vapour pressure is < 1.11 × 10-5Pa (25 DEG C).Partition coefficient LogP=0.67；
In water, dissolubility is 0.216mg/l (25 DEG C)；To light, heat, absolute acid stability, unstable to alkali.It is mainly used in preventing and kill off barnyard grass
With annual grassy weeds etc..With p-fluorophenol as initiation material, prepare the substituted Nitrobenzol of intermediate through chlorination, esterification, nitrification；
Intermediate substituted phenol potassium salt is prepared through hydrolysis；Substituted aniline is made in the most etherified, reduction；Last anti-with ethyl chloroformate
Ying Hou, i.e. obtains goal object with senecioic acid ester condensation.
Prosulfuron chemical name is 1-(4-methoxyl group-6-methyl isophthalic acid, 3,5-triazine-2-base)-3-[2-(3,3,3-trifluoro propyl) phenyl
Sulfonyl] urea, structural formula isFor sulfonylurea, sterling
For colorless and odorless crystalline solid；Fusing point 155 DEG C (decomposition)；Density 1.5 (20 DEG C)；Vapour pressure is < 3.5 × 10-6Pa (20 DEG C), distribution
Coefficient LogP (25 DEG C)=1.5 (pH 2) ,-0.21 (pH 6.9) ,-0.76 (pH 9.0)；Dissolubility (25 DEG C, g/l) is: in water 0.029
(pH 4.5), 0.087 (pH 5.0), 4.0 (pH 6.8), 4.3 (pH 7.7), ethanol 8.4, acetone 160, toluene 6.1, normal hexane
0.0064, ethyl acetate 56, dichloromethane 180；At room temperature deposit 24 months and stablize, can be rapid under the conditions of pH 5
Hydrolysis；pKa 3.76.Prosulfuron is the inhibitor of acetolactate synthestase (ALS) as other sulfonylurea herbicide.
Being absorbed by weeds root and leaf, conduct in plant body, weeds i.e. stop growing, leaf color chlorisis, the most withered.It is mainly used in
Prevent and kill off broad leaved weed.The weeds such as abutilon, Amaranthus, Chenopodium, Polygonum, Stellaria are had the preventive effect of excellence.
Both the above medicine, after long-term being used alone, the most easily makes plant pathogenic bacteria develop immunity to drugs, causes dosage to add
The problems such as greatly, preventive effect reduction, lasting period shortening.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of containing pentoxazone with the herbicide of prosulfuron
Suspending agent.Effective active composition pentoxazone, prosulfuron mutual mixture broad weed-killing spectrum in herbicide of the present invention；The present invention
Effective ingredient in herbicide coordinates good potentiation within the specific limits, and preventive effect is higher than single dose, and the property of medicine is held time length；
The safest to Oryza sativa L..
A kind of herbicide suspending agent containing pentoxazone and prosulfuron of the present invention is by following technical scheme
Realize: the effective ingredient of described herbicide includes: pentoxazone, prosulfuron, wherein, pentoxazone,
Prosulfuron accounts for 25-45 part of herbicide gross mass, also includes dispersant 5-20 part by weight, antifreezing agent 1-5 part,
Thickening agent 1-2 part, defoamer 0.5-1 part, water 50-80 part.
Described pentoxazone, the part by weight of prosulfuron are 1-20:1-20.
Further, pentoxazone, the part by weight of prosulfuron are 1-10:1-5.
Preferably, pentoxazone, the part by weight of prosulfuron are 7:2.
First other auxiliary agents are mixed, through high speed shear mix homogeneously, add pentoxazone, prosulfuron, at ball crusher
Middle abrading-ball 2-3 hour, makes a diameter all at below 5mm, prepares the suspending agent of this herbicide.
Described dispersant is lignosulfonates.
Described antifreeze glycol.
Described thickening agent xanthan gum.
Described defoamer is silicone oil.
This herbicide suspending agent is for Oryza sativa L., Semen Maydis and Sorghum vulgare Pers. postemergence weed control in early days.
Beneficial effects of the present invention:
In herbicide of the present invention, effective active composition pentoxazone, the mutual mixture of prosulfuron will not produce conflict；Broad weed-killing spectrum,
The most effectively kill the weeds after being unearthed, it is possible to control not to be unearthed weeds, improves herbicidal effect；Effective in herbicide of the present invention
Components matching has good potentiation within the specific limits, and preventive effect is higher than single dose, and the property of medicine is held time length, decreases pesticide anti-
Multiple access times, reduce Pesticide use amount, reduce the use cost of pesticide；The safest to Oryza sativa L., Semen Maydis and Sorghum vulgare Pers..The present invention
Suspensions stability good, easy to use, good dispersion, the ability sticking to plant surface is stronger, resistance of rainwater washing against, medicine
Persistently, penetration is strong, low cost for effect, and drug effect is high.
