Description
Technical field
The invention patent relates to pesticide herbicide technical field, it is especially a kind of containing diflufenican, pendimethalin and
The Herbicidal combinations of Oxyfluorfen.
Background technique
Diflufenican (diflufenican), chemical name N- (2,4 difluorobenzene base) -2- [(3- trifluoromethyl) benzene oxygen
Base] -3- pyridine anilide, it is a kind of herxheimer-liked reaction inhibitor, belongs to amine herbicide, weeds plant is absorbing
Carotenoid content can be gradually reduced after medicament, and so as to cause Destruction of Chlorophyll and cell rupture, it is de- that weeds show as young shoot
Color or white, until it is dead to wilt.It is mainly used for preventing and treating a variety of annual gramineous weeds such as corn and soybean and wheatland and certain
A little broadleaf weeds, it is especially obvious to clearvers, Veronica removal effect.
Pendimethalin (pendimethalin), chemical name N- (1- ethyl propyl) -2,6- dinitro -3,4- dimethyl
Aniline, before being a kind of selective bud, upland field soil handles herbicide after bud.The weed bud that it can sprouted absorbs, and makes
Obtain medicament causes weeds dead with tubulin binding after entering plant to inhibit the mitosis of plant cell,
It has been widely used in the various crops such as corn and soybean, peanut, cotton, direct-seeding dry rice, potato, tobacco, vegetables, Neng Gouyou
Effect prevention and treatment annual gramineous weed, part broadleaf weeds, such as nutgrass flatsedge, barnyard grass, herba digitariae, herba setariae viridis, semen euphorbiae, herba eleusines indicae, horse
Bitterroot, amaranth, Chenopodiaceae, piemarker, black nightshade, cyperus iria, anisotropic nutgrass flatsedge etc..
Oxyfluorfen is a kind of contact killing type herbicide, its activity of weeding is usually played in the case where there is light, main logical
Cross plumule, mesocotyl enters in plant, less through root absorption, only denier is transported up by root into leaf
Portion, before being widely used in cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, weeding after bud, to barnyard grass, sesbania,
Downy brome, herba setariae viridis, datura, quackgrass, artemisiifolia, secondary chrysanthemum twirl, piemarker, charlock unifacial leaf and broadleaf weeds have significantly
Control efficiency, while its very anti-leaching can be made into missible oil use.
Currently, common herbicide is mostly single dose in agricultural production, often effect is single, such as closes herbicide only to not going out
The weeds of soil are effective, then invalid to unearthed weeds, thus in order to reach different herbicidal effects, it is often necessary to repeatedly divide
Not Shi Yong a variety of special purposes herbicide, not only considerably increase medicine frequency and recruitment cost in this way, but also can be to work
Object and Environmental security threaten, and are used for a long time, are also easy to that weeds is made to develop drug resistance.Therefore suitable herbicide is screened to carry out
Compounding, which is used in mixed way, can not only effectively improve herbicidal effect, reduce dosage, reduce cost, and be conducive to delay weeds anti-
The generation of pharmacological property is of great practical significance simultaneously for complicated and diversified weed species are prevented and treated.
Summary of the invention
For the problems of the prior art, the purpose of the present invention is to provide a kind of component is reasonable, drug cost is low, is not easy

The pharmacodynamic test of 26 garlic field weeding composition pharmaceutical preparation of embodiment
The Herbicidal combinations medicament that Example 1 to embodiment 25 prepares carries out pharmacodynamic test, with 50% pyrrole fluorine acyl
Careless amine wettable powder 1,330 grams per liter pendimethalin missible oil, 2,240 grams per liter Oxyfluorfen as a control group as a control group
Missible oil as a control group 3, clear water is as blank control group.
(1) synergy effect of each group drug to be measured to weeds:
Co-toxicity coefficient method is used to evaluate the synergistic effect of Herbicidal combinations medicament provided by the invention: dense with composition medicament
The natural logrithm of degree (X) is asked with growth inhibition percent or fresh weight suppression percentage (Y) of the composition medicament to target weeds
Regression equation, and composition medicament is calculated to the EC of weeds50Value or EC90Value, then acquires co-toxicity coefficient.With co-toxicity coefficient
Complex composition medicament is evaluated to the synergy effect of weeds, co-toxicity coefficient > 120 are expressed as synergistic effect, and co-toxicity coefficient exists
Summation action is expressed as between 80~120, co-toxicity coefficient < 80 are expressed as antagonism.
The co-toxicity coefficient calculation formula used in the present embodiment is as follows:
Co-toxicity coefficient (CTC)=100/ (ECIt is mixed×PDiflufenican/ECDiflufenican+ECIt is mixed×PPendimethalin/ECPendimethalin+ECIt is mixed×
POxyfluorfen/ECOxyfluorfen)
In formula: ECIt is mixedFor the EC of composition medicament50It is worth (to clearvers, shepherd's purse, herba digitariae, herba setariae viridis, similarly hereinafter)；PDiflufenicanFor
Diflufenican shared mass ratio in composition medicament effective component；PPendimethalinIt is effective in composition medicament for pendimethalin
Shared mass ratio in ingredient；POxyfluorfenFor Oxyfluorfen in composition medicament effective component shared mass ratio；
ECDiflufenicanFor the EC of diflufenican50Value；ECPendimethalinFor the EC of pendimethalin50Value, ECOxyfluorfenFor the EC of Oxyfluorfen50
Value.Each group of other EC50Value and co-toxicity coefficient are shown in Table 1.
The EC of 1 each group of table other drug to be measured50Value and co-toxicity coefficient
By 1 experimental result of table it is found that diflufenican provided by the invention, pendimethalin, Oxyfluorfen compounding after institute
Herbicidal combinations, diflufenican, pendimethalin, Oxyfluorfen mass ratio in 1~10:10~30:1~10,
Co-toxicity coefficient is all far more than 120, illustrates that diflufenican, pendimethalin, Oxyfluorfen after compounding, produce apparent increasing
Effect effect.
(2) cauline leaf process control efficiency of each group drug to be measured to various weeds
It tests and is carried out in Henan Zhongmou County garlic field, each group handles 4 repetitions, and processing area is 20m2；Implement
Example 1 is another that (the 34% pendimethalin Oxyfluorfen of control group 4 is arranged to embodiment 25, control group 1, control group 2, control group 3
Missible oil).Application method: soil sprays before seedling after garlic is broadcast for embodiment 1 to embodiment 25, control group 2, control group 3, control group 4
Mist processing, control group 1 is 15 days after weeds 1-2 leaf phase spraying treatment, medicine, 30 days statistics prevent and treat result.Test process, formulation rate
And control efficiency is shown in Table 2.
Preventive effect calculation formula are as follows: strain preventive effect (%)=(check plot weeds strain number-treatment region weeds strain number)/check plot weeds
Strain number × 100
The each group of 2 garlic field weed of table processing medication administration amount to be measured and control efficiency
By 2 test result of table it is found that diflufenican, pendimethalin or Oxyfluorfen and 34% 2 compared to single agent
The clever oxyfluorfen EC of first penta, gained removes after diflufenican provided by the invention, pendimethalin, Oxyfluorfen compounding
The herbicidal effect of careless composition will be apparently higher than four control groups, and significant difference (P < 0.05), synergistic function is obvious, simultaneously
Degrass spectrum has also been enlarged.
In conclusion Herbicidal combinations provided by the invention compound diflufenican, pendimethalin, Oxyfluorfen
Afterwards, reach cooperative synergism effect, expand degrass spectrum, the confrontation stronger weeds of pharmacological property can also effectively prevent, environmentally safe
It has no adverse effects, can be used for preventing and treating weeds in field.
The foregoing description of the disclosed embodiments can be realized those skilled in the art or using the present invention.To this
A variety of modifications of a little embodiments will be apparent for a person skilled in the art, and the general principles defined herein can
Without departing from the spirit or scope of the present invention, to realize in other embodiments.Therefore, the present invention will not be limited
It is formed on the embodiments shown herein, and is to fit to consistent with the principles and novel features disclosed in this article widest
Range.
