Description

A kind of containing butafenacil with the Herbicidal combinations of penoxsuam

Technical field

The invention belongs to technical field of pesticide, it is effective for being specifically related to one with butafenacil, penoxsuam The Synergistic Herbicidal combinations of composition, it is adaptable to prevent and kill off bare place, orchard, vine crop field weed.

Background technology

Butafenacil (butafenacil), non-selective uracil weeding agent, be mainly used in orchard, Important broad leaved weed, grassy weed and sedge weed is prevented and kill off in bare place, Cotton Fields, vine crop field, Can also be used for weeding before the crop Seedlings such as Semen Tritici aestivi, weeding effective dose is more than 50 grams per hectares of effective ingredient consumption.

Penoxsuam is translocated herbicide, through stem and leaf, plumelet and Root Absorption, by xylem and tough Skin zone's conduction, to separate living tissue, suppresses plant strain growth, makes growing point chlorosis, and after process, 7-14d terminal bud reddens, Necrosis, 2-4 week plant is dead；Penoxsuam is rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass, thousand Gold and annual sedge weed, and effective to numerous broad leaved weeds.

By test, it has been found that butafenacil and penoxsuam mixture according to a certain percentage, to Cyprinus carpio intestinal (Eclipta prostrata, ECLPR), sesbania (Sesbania exaltata, SESEX), ring flower (Commelina diffusa, COMDI), Herba monochoriae vaginalis (Monochoria vaginalis, MONVA), barnyard grass (Echinochloa crusgalli, ECHCR), Semen Euphorbiae (Leptochloa chinensis, LEPCH), Herba Imperatae (Imperata cylindrica, IMPCY), Bermuda grass (Cynodon dactylon, CYNDA), Herba Erodii (Geranium wilfordii, GERWI), morning glory (Pharbitis nil, PHANI), The weeds such as grass (Humulus scandens, HUMSC) have synergistic function, after further study, complete Become the present invention.

Do not find the compounding relevant report of butafenacil and penoxsuam at present.

Summary of the invention

It is an object of the invention to solve in prior art, farmland weed is developed immunity to drugs problem and actual preventing and treating Effect is poor, it is provided that one is efficiently, low toxicity, quick-acting are good and the lasting period is long, and beneficially farmland weed is comprehensive The Herbicidal combinations administered.

It is another object of the present invention to be used for preventing and kill off farmland weed by this Herbicidal combinations, be particularly useful for preventing and kill off fruit Garden, bare place, vine crop field, Cotton Fields weeds.

The technical scheme is that a kind of containing butafenacil with the Herbicidal combinations of penoxsuam, have Effect composition is that the ratio of weight and number of butafenacil and penoxsuam, butafenacil and penoxsuam is 30:1～1:30.

The Herbicidal combinations of the present invention can use uses known method, selects suitable auxiliary agent to be prepared as being suitable for agriculture In industry use any one dosage form, reasonable dosage form have suspending agent, oil-suspending agent, water dispersible granules, Wettable powder.The processing technique of the various preparation of the present composition is prior art, according to different situations Can be varied from.

The auxiliary agent used in Herbicidal combinations of the present invention includes solvent, emulsifying agent, wetting agent, stabilizer, divides Powder, thickening agent, pH adjusting agent, defoamer, antifreezing agent, packing agent etc. are of value to effective ingredient at preparation In stable and play the known substance of drug effect, be all conventional in pesticidal preparations or allow the various compositions used, Concrete composition and consumption are determined by test according to recipe requirements.

Product described in the invention can provide with the form of finished product preparation, and i.e. in compositions, each material has mixed Closing, the composition of compositions can also the form of single dose provide, and directly mixes in tank or bucket, then before using It is diluted to required concentration.The frequency of administration of the present composition and amount of application are with weather conditions and weeds feelings Condition changes and changes, and can reach, by using suitable dosage, the purpose prevented and kill off.

The frequency of administration of Herbicidal combinations of the present invention and amount of application with crops, weeds, weather condition change and There is small variations, can reach, by using suitable dosage, the purpose effectively prevented and treated.

The present invention expands weed control spectrum, and compositions has Synergistic response to target, can be bare place, really Garden, Cotton Fields, vine crop field weed offer excellent fix is provided, weeds comprehensive control is had Positive effect.

Detailed description of the invention

In order to make the purpose of the present invention, technical scheme and advantage more short and sweet, the present invention is with in detail below Embodiment illustrates, but the present invention is only limitted to absolutely not these examples.It is preferable that the following stated is only the present invention Embodiment, is used only for describing the present invention, it is impossible to be interpreted as limiting the scope of the present invention.Should be understood that , all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, all Within protection scope of the present invention should being included in.

Embodiment one: Assays Example.

Butafenacil, penoxsuam and compounding to sesbania (Sesbania exaltata, SESEX=sesbania), Ring flower (Commelina diffusa, COMDI=ring flower), Semen Euphorbiae (Leptochloa chinensis, LEPCH=Semen Euphorbiae) interior toxicity test.

Evaluating herbicide associated form (NY/T1155.7-2006) according to Gowing method, its formula is as follows:

$E_0=X+Y-\frac{X\×Y}{100}.$

In formula:

X is butafenacil with certain dosage fresh weight inhibition to target weeds time alone；

Y is penoxsuam with certain dosage fresh weight inhibition to target weeds time alone；

E₀For when butafenacil, two kinds of pharmacy mix of penoxsuam to the theoretical value of target weeds fresh weight inhibition or Desired value；

It is the reality of comparison to target weeds fresh weight inhibition when E is butafenacil, two kinds of pharmacy mix of penoxsuam Measured value or observation.

Evaluation criterion: as E E₀During ＞ 10%, it is expressed as synergistic function；As 10%≤E E₀When≤10%, Show as collaborative summation action；As E E₀During ＜ 10%, show as joint action of antagonism.
