Description
Technical field
The present invention relates to pesticide processing field, more particularly to a kind of effervescent tablet containing fenoxaprop active ingredient
And preparation method thereof.
Background technology
One of an important factor for weeds in paddy field is influence yield and quality of rice, can generally cause rice underproduction 10%-
20%, up to more than 50%, even No kernels or seeds are gathered, as in a year of scarcity for the underproduction when serious.Especially now increasing peasant using direct seading rice,
The light cultivation pattern such as machine-transplanted rice and Throwing seedling rice, because sowing is early, do not transplant, Weed infestation is more serious.
China's paddy field weed-killer is mainly the strategy using " inside front cover kills three benefits " at present." envelope " is before broadcasting or is broadcast
Before seedling carries out soil closing to rice field afterwards, and this measure is the key of Weed Control in Direct-sowing Rice Field." two kill ", it is for applying for the first time
The weeds still to be survived after medicine, and the simultaneous weeds for controlling second peak generation, usually in the rice 4-6 leaf phases." three mend " be as
Fruit weeding early stage is failed, and still there is the supplement prophylactico-therapeutic measures taken during a great deal of weeds generation in field.
Because rice field mud is more, walking in rice field, dispenser is all very tired and difficult, and labor intensity is especially big.Especially
Be stay in now rural area farming be all the elderly, it is difficult to undertake high labor intensity dispenser operation.
The content of the invention
It is an object of the invention to provide a kind of dispenser it is simple and quick, reduce labor intensity, Jing Evil are contained to rice safety
The effervescent tablet of azoles diclofop-methyl active ingredient.
The technical solution adopted by the present invention:A kind of effervescent tablet containing fenoxaprop active ingredient, including it is as follows

One or both of fluroxypyr, dichloro quinolinic acid, bentazone, azoles humulone, benthiocarb.
The present invention effect be:Labor intensity is significantly reduced, easy to use, saving of work and time is laborsaving, without dust pollution, no
Need medical instruments;Other effervescent tablet accumulating is convenient, easy to use.
The invention further relates to following technical scheme:A kind of effervesce as described above containing fenoxaprop active ingredient
The preparation method of tablet, comprises the following steps:S1:By first active component and the second active component, solid acid, titanium dioxide
Carbon source, wetting dispersing agent, drier, filler are dried and crushed respectively, then are pre-mixed, and are blended into the binding agent mixing,
The mixture of gained crosses standard screen;S2:The mixture is directly granulated in comminutor, that is, obtains effervescent tablet.
The present invention effect be:Prepared effervescent tablet significantly reduces labor intensity, easy to use, and saving of work and time saves
Power, without dust pollution, it is not necessary to medical instruments;Other effervescent tablet accumulating is convenient, easy to use.

The invention further relates to a kind of preparation method of the effervescent tablet containing fenoxaprop active ingredient, including it is following
Step:S1:Jiang fenoxaprop and other herbicides, solid acid, carbon dioxide source, wetting dispersing agent, drier, filler point
It is not dried and crushes, then be pre-mixed, be blended into binding agent mixing, the mixture of gained crosses 325 mesh standard sieves;S2:Making
Said mixture is directly granulated in grain machine, that is, obtains effervescent tablet.The shape of the effervescent tablet be spherical, column, plate-like or
Sheet.
Fenoxaprop is a kind of efficient aromatic oxygen-phenoxy group propionates class herbicide, mainly applies to broad leaf crop field
Grassy weed is prevented and kill off, coordinates safener to prevent and kill off the grassy weed of wheat paddock.Generally Jiang fenoxaprop and cyanogen
Fluorine grass ester and penoxsuam compounding control rice field grassy weed, and excellent herbicidal effect is shown, obtain in production
Promote.Used in the local fenoxaprop such as Malaysia, India on rice., fenoxaprops simultaneously
Poisoning be present to rice, rice strain yellow, growth inhibition can occur in rice early application, but dispenser is to rice ratio after 5 leaves
It is safer.
It is most of to be absorbed by rice root because effervescent tablet is applied in paddyfield water, it is a small amount of to reach rice stem,
And it is different from traditional cauline leaf process mode.It is experimentally confirmed that being used for cauline leaf process fenoxaprops all the time, work as processing
After being absorbed into effervescent tablet by rice root or basal part of stem, the poisoning to rice is significantly reduced, increases rice Dui Jing Evil
Azoles diclofop-methyl endures concentration range, changes to be formerly only available and applies Jing oxazole dogstail using cauline leaf process after the leaf phase of rice 5
Spirit, fenoxaprop effervescent tablet the heart stage of 2 leaf of rice one 2 times amount even 4 times amount under be all safe to rice.And
And effervescent tablet enters in water and produces bubble, rapid disintegration, herbicide active ingredient is set uniformly to be distributed in water, Ke Yizhi
Connect throwing to be applied in rice terrace, it is not necessary to special medical instruments.
In this way, instant invention overcomes labor intensity is big, spray pattern is low during the administration of existing herbicides for use in paddy, dispenser when to applying
The shortcomings of medicine person is dangerous, labor intensity is significantly reduced, easy to use, saving of work and time is laborsaving, without dust pollution, it is not necessary to medicine
Tool;Other effervescent tablet accumulating is convenient, easy to use.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
