Description
Technical field
The invention belongs to herbicide technology fields, and in particular to a kind of fluridone complex weedicide and preparation method thereof.
Background technique
In agricultural production process, serious, the target crops such as damage to crops, forest occur for unwanted plant (weeds)
Growth, and influence not expecting vegetation plot (such as bare place, railway, highway, forest fire protection road, industrial sites, threshing ground)
Normal use.Herbicide is to prevent and kill off the method the most economic, quick and effective for not needing plant.It is current market sales of
Single dose kind Oxyfluorfen, oxadiazon, Acetochlor etc. are used for a long time, have many weeds to generate resistance, dosage
Greatly.
Summary of the invention
The technical problem to be solved by the present invention is providing, a kind of safety and environmental protection, herbicidal effect is good, is not easy to develop drug resistance
Fluridone complex weedicide and preparation method thereof.
To achieve the above object, The technical solution adopted by the invention is as follows:
It, can be with arbitrary proportion mixture, a kind of usual activity between A and B between medicament in present composition component A
Component content is higher than rest activity ingredient, and preferably mixing ratio is 100:1 to 1:100 or 50:1 to 1:50.
Fluridone: raw medicine is white crystalline solid, can be used for wheat, rice, corn and pasture selective herbicidal.It is right
In terrestrial plant, mainly by root absorption, conduction to blade reduces carotenoid by inhibiting lycopene dehydrogenase
Chlorophyll is lost in biosynthesis, inhibits photosynthesis.Usual amounts: 189-252g (a.i)/hm2, but single herbicide
Using drug resistance is easy to produce or prevention spectrum is limited, the harm that production does not need plant in practice not can be well solved.It is mixed
With herbicide have can expand prevention spectrum, enhancing preventive effect, delay the advantages such as herbicide resistance, in production practice become most by
The application form of welcome.Herbicide especially with synergy, it is such as multiple with Oxyfluorfen and sulfone pyrrole grass azoles herbicide
Match, interact between each active principle, make combination aging fruit better than the theoretical summation of exclusive use effect, thus actually makes
Used time can play a multiplier effect, and more be welcome by user.
Oxyfluorfen: cotton field degrass spectrum: black nightshade, barnyard grass, sesbania, downy brome, herba setariae viridis, datura, quackgrass,
Artemisiifolia, acalypha copperleaf, Thorn-Apple, thorn chrysanthemum twirl, piemarker, Siberian cocklebur, charlock, rhizome of nutgrass flatsedge etc., to grass family, Cyperaceae and broad-leaved
Grass is effective.
The mode of action: before selective bud or after bud
The mechanism of action: playing its activity of weeding in the case where there is light, mainly enters plant by plumule, mesocotyl
In vivo, less through root absorption, and there is denier to be transported up by root into leaf portion.
Usual amounts: 144-216g (a.i)/hm2
Sulfone pyrrole grass azoles:
Cotton field degrass spectrum: a series of gramineae weeds such as setaria, knotgrass, Echinochloa, Panicum, Sorghum and eggplant
The broadleaf weeds such as category, Amaranthus, Datura, abutilon, Chenopodium
The mode of action: before selectivity, bud
The mechanism of action: it is absorbed by weeds young root and young shoot after application, inhibits seeding previous vigor, destroys separate living tissue
It is serious potential inhibition in VLCFA in plant (extremely long branched fatty acid) (C20~C30) biosynthesis with plumule
Agent, it is special that VLCFA in plant is inhibited to extend C18: 0 to C20: 0, C20: 0 to C22: 0, C22: the 0 to C24: 0 of enzymatic,
In C24: 0 to C26: 0 and C26: 0 to C28: 0 extension stage, in addition, from C18: 1 to C20: 1 and C20: 1 to C22: 1 prolongs
It is also suppressed to stretch the stage.
Usual amounts: 125-250g (a.i)/hm2
It is using the beneficial effect of technical solution of the present invention:
1, mixed composition has good synergistic effect, and application effect is substantially better than single dose theoretical effect summation, that is, has
There is super superposition, can preferably control dominant weed occurrence injury；
2, there is good complementarity in control of weeds spectrum between mixed composition active constituent, can expands very well anti-
Spectrum is controlled, synthesis effectively controls various weeds occurrence injuries；
3, mixed composition has good synergistic effect, can reduce pharmaceutical use, reduces use cost and environment is dirty
Dye improves the safety to crop.
4, sulfone pyrrole grass azoles is as new product, and anti-grass is active very high (8-10 times of Acetochlor), and dosage is few, and weeds almost do not have
It is resistant.Fluridone, sulfone pyrrole grass azoles can not only make up ethoxy fluorine grass as disposable herbicide before novel bud and after seedling
Ether, the deficiency of the old products such as Acetochlor can expand degrass spectrum, while weeds can be delayed to sulfone pyrrole grass azoles and fluridone
Drug resistance extends the service life of new product.
