Abstract
The present invention relates to a kind of rice herbicide cream preparation.Effective active composition pentoxazone, pyraflufen-ethyl mutual mixture broad weed-killing spectrum in herbicide of the present invention；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；The safest to paddy rice.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of rice herbicide cream preparation.
Background technology
Pentoxazone, chemical name 3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl)-5-isopropyl alkene-1,3-oxazoles
Quinoline-2,4-diketone, structural formula, belong to oxazoline ketone, sterling
For powdery solid colourless, tasteless；Fusing point 104 DEG C；Density 1.418 (25 DEG C)；Vapour pressure is < 1.11 × 10-5Pa (25 DEG C).Point
Distribution coefficient LogP=0.67；In water, solubility is 0.216 mg/l (25 DEG C)；To light, heat, absolute acid stability, unstable to alkali.Main
It is used for preventing and kill off barnyard grass and annual grassy weeds etc..With p-fluorophenol as initiation material, in chlorination, esterification, nitrification prepare
The substituted nitrobenzene of mesosome；Intermediate substituted phenol sylvite is prepared through hydrolysis；Substituted aniline is made in the most etherified, reduction；
After finally reacting with ethyl chloroformate, i.e. obtain object with senecioic acid ester condensation.
Pyraflufen-ethyl chemical name is the chloro-5-of 2-[4-chloro-5-difluoro-methoxy-1-methylpyrazole-3-base]-4-fluorobenzene oxygen second
Acetoacetic ester, structural formula is, for pyrazoles, sterling is
Brown solid；Fusing point 126 ~ 127 DEG C；Vapour pressure is 4.79 × 10-3Pa (25 DEG C).In water, solubility is < 1ppm (25 DEG C).
Solubility (25 DEG C, % weight) in other solvent: dimethylbenzene 2.9, acetone 25.0, ethanol 1.0, ethyl acetate 14.5.Rat is anxious
Property per os L D50: > 5000mg/kg；This product is non-stimulated to lagophthalmos eyeball and rabbit skin.Ichthyotoxin L C50 (when 48 little 295): carp
And rainbow trout > 10ppm.A m e s test is negative.Without mutagenicity.Pyraflufen-ethyl is contact killing type herbicide, passes through plant cell
Middle protogen IX accumulates and plays drug effect.After cauline leaf processes, it can be rapidly absorbed in plant tissue, makes plant the worst
Extremely, or under sunlight irradiates, make cauline leaf dehydration withered.Be mainly used in preventing and kill off broad leaved weed such as clearvers, deaf nettle, chickweed,
Veronica persica, scentless mayweed etc..
Both the above medicine, after long-term being used alone, the most easily makes plant germ develop immunity to drugs, causes medication
The problems such as amount increasing, preventive effect reduction, lasting period shortening, are unfavorable for environment sustainable development.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of rice herbicide cream preparation.Weeding of the present invention
Effective active composition pentoxazone, pyraflufen-ethyl mutual mixture broad weed-killing spectrum in agent；Active ingredient in herbicide of the present invention is joined
Closing and have good synergistic effect within the specific limits, preventive effect is higher than single dose, and the property of medicine is held time length；The safest to paddy rice.
A kind of rice herbicide cream preparation of the present invention is to be realized by following technical scheme: described weeding
The active ingredient of agent includes: pentoxazone, pyraflufen-ethyl.Wherein, pentoxazone, pyraflufen-ethyl account for the 60-of herbicide gross mass
80 parts, also include emulsifying agent 5-15 part by weight, solvent 30-50 part.
Described pentoxazone, the part by weight of pyraflufen-ethyl are 1-20:1-20.
Further, pentoxazone, the part by weight of pyraflufen-ethyl are 10-20:1.
Preferably, pentoxazone, the part by weight of pyraflufen-ethyl are 17:1.
Pentoxazone, pyraflufen-ethyl are dissolved in a solvent, adds emulsifying agent, be uniformly mixed and i.e. prepare this herbicide
Cream preparation.
Described emulsifying agent is the mixture of calcium dodecyl benzene sulfonate and castor oil polyoxyethylene ether.
Described solvent is the mixture of dimethylbenzene and turpentine oil.
This Emulsionable herbicides preparation before the rice seedlings or in early days postemergence weed control.
Beneficial effects of the present invention:
In herbicide of the present invention, effective active composition pentoxazone, the mutual mixture of pyraflufen-ethyl will not produce conflict；Herbicide
Spectrum is wide, the most effectively kills the weeds after being unearthed, it is possible to control not to be unearthed weeds, improves herbicidal effect；In herbicide of the present invention
Active ingredient coordinate and have good synergistic effect within the specific limits, 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, reduces the use cost of agricultural chemicals；The safest to paddy rice.
