The fluroxypyr weed killer herbicide is a wheat paddock weed killer herbicide commonly used, and broad leaved weed clearvers, kitchen garden, black nightshade, field bindweed, knotweed, amaranth, Commeline communis, field bindweed, descurainia sophia (l.) webb ex prantl, vetch etc. are had good preventive effect.Absorbed by ruderal plant very soon after the fluroxypyr dispenser; Make the susceptible weeds plant reaction of typical hormone herbicide occur; Plant deformity, distortion, finally withered, be applicable to that wheat, barley, corn, grape, orchard, pasture, forest land, lawn etc. prevent and kill off broad leaved weed.But the wheat paddock weeds are main weeds with grassy weed and broad leaved weed, and fluroxypyr can only be prevented and kill off broad leaved weed, to serving as that the grassy weed of typical case's representative does not have preventive effect with bromegrass, hard grass.In order to protect wheat to avoid weeds harm in all directions, need to use multiple weed killer herbicide, so just increase the risk of antagonism between each weed killer herbicide, and increased dosage, increased cost, the safety of harm environment and succession crop.
Summary of the invention
In view of this, the object of the invention provides a kind of wheat paddock Herbicidal combinations and preparation thereof, makes the present invention can prevent and kill off grassy weed and broad leaved weed simultaneously, and has synergistic effect to preventing and kill off grassy weed.
For realizing the object of the invention, the present invention adopts following technical scheme:
A kind of wheat paddock Herbicidal combinations is made up of pyridine sulphur grass amine and fluroxypyr.
Fluroxypyr; Belong to and inhale conduction selectivity herbicide after seedling in the pyridines; Its mechanism of action has changed the configuration of mitochondrial volume and mitochondrial membrane for promoting the activity of adenosine triphosphatase, has suppressed respiration and has disturbed metabolism of nucleic acid; Finally cause weeds dead, be widely used in and prevent and kill off broad leaved weed.
Pyridine sulphur grass amine belongs to sulfonamides inner sucting conduction type, selectivity winter wheat field herbicide after seedling, and broad weed-killing spectrum, activity of weeding is high, drug action is fast.Its mechanism of action is the inhibitor of acetolactate synthestase (ALS), absorbs via grass cutting blade, sheath portion, stem or root, accumulates at growing point; Suppress the synthetic of acetolactate synthestase; Cause to synthesize branched-chain amino acid, and then influence protein synthesis, influence the weeds cell division; Cause weeds to stop growing, dead then.Grassy weed and broad leaved weeds such as wheatland amur foxtail, Japanese amur foxtail, hard grass, bromegrass, wild oat, Veronica, descurainia sophia (l.) webb ex prantl, shepherd's purse, chickweed, rice crock, Herb of Common Nipplewort can be effectively prevented and kill off, and weeds such as annual bluegrass, clearvers, wartwort can be effectively suppressed.
In weight portion; As preferably; Herbicidal combinations according to the invention is made up of 1-90 part pyridine sulphur grass amine and 1-90 part fluroxypyr, more preferably is made up of 2-10 part pyridine sulphur grass amine and 20-50 part fluroxypyr, most preferably is by 6 parts of pyridine sulphur grass amine and 45 parts of fluroxypyrs and forms.
Different herbicidal activity components mix each active component of back because the difference of composition, structure, physicochemical property makes that the synergy between each active component is typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and the effect of its generation is greater than the sum total of each composition effect; And being exactly the effect of its generation, summation action equals the sum total of each composition effect; Antagonism is meant that a kind of material disturbed the effect of another kind of material when two kinds of materials acted on living organism, or the effect of interfering with an opponent each other, the phenomenon that general effect is descended.
The present invention calculates co-toxicity coefficient evaluation pyridine sulphur grass amine and fluroxypyr and uses effect with according to Sun Yunpei (Sun Y-P) method, and the result shows co-toxicity coefficient all greater than 120, shows that the mixing use of the two has the notable synergistic effect.
In addition; The present invention has carried out the control of weeds test to each single-activity composition in said Herbicidal combinations and the Herbicidal combinations respectively; And each active component consumption is less than this absorption of active ingredient of single use in the said Herbicidal combinations, and the result shows that the preventive effect of Herbicidal combinations according to the invention is higher than the preventive effect of single use active component; Show that each active component does not have cross tolerance in the Herbicidal combinations according to the invention, control efficiency has synergistic effect.
In addition, the present invention also provides a kind of weed killer herbicide, is made up of acceptable auxiliary material on Herbicidal combinations according to the invention and the pesticidal preparations, and the percentage by weight that said Herbicidal combinations accounts for said weed killer herbicide is 10-90%.
