Description
Technical field
The present invention relates to direct seading rice field annual grassy weeds Prevention Technique field, be specifically related to a kind of pyribenzoxim and
Cyhalofop-butyl compounded cream and preparation method thereof.
Background technology
At present, the existing Herbicidal combinations prevented and treated for direct seading rice field annual grassy weeds, such as Chinese patent " CN
104054734 A " are disclosed a kind of " herbicide for paddy field ", including effective active composition, auxiliary agent and carrier, wherein, it is effectively living
Property composition mass percent be 31-60%, the mass percent of auxiliary agent is 11-19%；The effective active composition is by isopropyl
Grand, clomazones and halosulfuronmethyl composition, their mass parts in effective active composition are followed successively by 1~5 part, 8~25 parts
With 8~30 parts.In addition, Chinese patent " A of CN 105994333 " discloses a kind of " rice direct seeding field annual grassy weeds weeding
Agent ", including pyrazosulfuron, clomazones and butachlor active compound；Wherein, butachlor, clomazones and pyrazosulfuron active compound press 30：
4：1 ratio is compounded；After compounding, pyrazosulfuron, clomazones and butachlor active compound account for the 1-80% of herbicide gross mass.
Inventor verifies that above-mentioned several Herbicidal combinations are primarily present following defect by long term test：
1), by testing several specific proportionings disclosed in above-mentioned several Herbicidal combinations, find to direct seading rice
Field annual grassy weeds can not play good prevention effect.
2), for several formulations disclosed in above-mentioned several Herbicidal combinations, find there is difference by verification experimental verification
The defect of problem.For example, the wettable powder being made easily causes product to bond, it is difficult in water to disperse suspension, or block spray
Head, in sprayer reason precipitation etc. phenomenon, cause sprinkling it is irregular, easily make crop locally produce poisoning, itself main reason is that
There are different defects in the selection of auxiliary agent and filler.
3) problem, is compounded, by carrying out virulence test, heat to several specific proportionings disclosed in above-mentioned several Herbicidal combinations
Store stability test and co-toxicity coefficient is determined and found, be unable to reach obvious addition synergistic effect.
The content of the invention
An object of the present invention is to provide a kind of pyribenzoxim and cyhalofop-butyl compounded cream, and missible oil design is closed
Reason, the prevention effect to direct seading rice field annual grassy weeds is good, and can realize the notable synergistic of pyribenzoxim and cyhalofop-butyl
Effect.
To achieve the above object, present invention employs following technical scheme：
A kind of pyribenzoxim and cyhalofop-butyl compounded cream, is at least made up of the component of following parts by weight：
Pyribenzoxim is novel oxime ester compound, wide spectrum selective post-emergence herbicide.Mechanism of action and sulfonylureas
Class and the slow-witted type herbicides of imidazoles are similar, belong to acetolactate synthestase (ALS) inhibitor.To paddy rice, common wheat, Korea lawn grass
With activity of weeding after selective ultra high efficiency bud, activity of weeding before no bud, for preventing and kill off careless scale, big fringe amur foxtail, peppery few etc. each
Plant grassy weed and broad leaved weed effect is distinguished, to paddy rice, common wheat safety.Energy after slower 1 dispenser of chemical weeding speed
Suppress weed growth.Weeds Mortality Ratio is absorbed into from pyribenzoxim slower, generally require 1-3 weeks.Weeds are after administration
Symptom it is as follows：The tender shoots atrophy of four leaf stage, causes death.The old leaf of two leaf stage is changed very little, and keeps green.
Ammonia fluorine grass ester belongs to aryloxyphenoxypropionic class herbicide, is only to paddy rice in fragrant phenoxy phenoxy propionic acid herbicide
Kind with tight security, is also uptake and translocation herbicide as such other kind.By plant blade and
| leaf brings up absorption, and bast conduction accumulates the meristem zone in plant, resists second and drink completing of coacetylase enzyme (ACCase), make
Aliphatic acid synthesis stops, and the growth division of cell can not be normally carried out, and the destruction of the structure containing fat such as membranous system finally results in plant dead
Die.
The pyribenzoxim and cyhalofop-butyl compounded cream of the present invention, its advantage is shown：
1) missible oil that, prepared by the present invention is bright in terms of stability of emulsion, low-temperature stability etc. and heat storage stability

Gowing methods evaluate the two mixed synergy type to barnyard grass.The actual preventive effect of mixe herbicide is calculated as follows：
E0=X+Y (100-X)/100
In formula：X is the fresh weight preventive effect to barnyard grass when pyribenzoxim consumption is P；
Y is that cyhalofop-butyl consumption is that Q is fresh weight preventive effect to barnyard grass；
E0It is that Q is fresh weight to barnyard grass to fresh weight preventive effect+cyhalofop-butyl consumption of barnyard grass when for pyribenzoxim consumption being P
Preventive effect；
E is the actual preventive effect of mixe herbicide.
E-E0＞ 10% is synergistic effect；E-E0＜ -10% is antagonism；E-E0Value is to add between theoretical value ± 10%
Into effect.
2.3.2, activity test of the medicament to Procumbent Falsepimpernel
Point is sowed at the sectional area 0.25m equipped with soil after vernalization after Procumbent Falsepimpernel seed-soaking2Basin in, remaining same 2.3.1.
2.3.3, activity test of the medicament to Monochoria vaginalis
Point is sowed at the sectional area 0.25m equipped with soil after vernalization after Monochoria vaginalis seed-soaking2Basin in, remaining same 2.3.1.
3rd, interpretation of result and discussion
The mixture of embodiment 1-6 totally 6 different compound proportions is to the E-E of barnyard grass0Value is followed successively by 12.45%, 2.57%,
3.20%, 2.38%, 1.70%, 18.95%；To the E-E of Procumbent Falsepimpernel0Value is respectively 11.10%, 2.88%, 3.45%,
2.37%, 1.85%, 17.68%；To the E-E of Monochoria vaginalis0Value is respectively 13.22%, 2.57%, 3.48%, 2.37%,
1.35%, 20.80%.So as to which the synergy for the compound proportion for illustrating embodiment 1 and 6 belongs to obvious addition synergistic effect,
And the synergy of other embodiment substantially belongs to addition.Meanwhile, it be can be seen that by the experiment of embodiment 6 in compounding
It with the addition of in missible oil after a small amount of moracenin, the compounding synergy of pyribenzoxim and cyhalofop-butyl can be made further to carry
Rise.
