The Herbicidal combinations A+B1 that this invention is related, A+B2, A+B3 is used for corn, A+B4, A+B12 is used for corn and soybean, A+B9, A+B10, A+B11 is used for soybean, A+B13 is used for rape, control lady's-grass (Digitaria sanguinalis), green foxtail (Setaria viridis), wild oat (Avena fatua), salsola collina (Salsola collina), Amaranthus retroflexus (Amaranthusretroflexus), acalypha copperleaf (Acalypha australis), kitchen garden (Portulacaoleracea), black nightshade (Solanum nigrum), Ben Shi knotweed (P.bungeanum Turcz), lamb's-quarters (Chenopodium album), Siberian cocklebur (Xanthium sibiricum), piemarker (Abutilontheophrasti Medicus), field thistle (Cirsium segetum), meadow pine (Equisetumarvense), chickweed upland field weeds such as (Stellaria media).
The Herbicidal combinations A+B5 that this invention is related, A+B6, A+B8, A+B7+B5, A+B7+B6, A+B7+B8 can be used for paddy field control barnyard grass grass (Echinochloa crusgalli), the short arrowhead of moleplant seed (Leptochloachinensis) (Sagittaria pygmaea), wolf tail grass (Bidens tripartita), Monochoria vaginalis (Monochoria vaginalis), pondweed (Potamogeton distinctus), difformed galingale herb (Cyperus difformis), firefly Lin (Scirpus juncoides), flat stalk bit of a bridle grass paddy land weeds such as (Scirpisplaniculmis).
The present invention is used for using in early days behind crop preemergence application or the seedling.Term " preemergence application " is illustrated in crop, weeds and grows the processing of spraying of soil in the crop-planting field that soil surface exists with the forward direction weeds." use in early days behind the seedling " to be illustrated in and in the crop-planting field, carry out cauline leaf spraying processing during the phase at weeds 1～2 leaf.The method of handling can be by using manufactured composite preparation or before use the different activities component being mixed and carried out.
Herbicidal composition involved in the present invention is wetting powder and suspending agent preferably.Also can be other formulations such as missible oil, pulvis and granule.
Adoptable surfactant has anionic surfactant and nonionic surface active agent.The aliphatic alcohol sulfate that comprises Sulfates, alkylol polyoxyethylene groups ether sodium sulfate, alkylol polyoxyethylene groups ether sodium sulfate etc., the sodium alkyl sulfonate of Sulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate, dialkyl succinylsuccinate sulfonate, monoalkyl phenyl polyoxyethylene groups ether succinic acid sodium sulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate, aliphatic alcohol polyethenoxy base ether, alkylphenol-polyethenoxy base ether, the anhydrous sorbitol fatty acid ester, anhydrous sorbitol aliphatic acid polyethenoxy base ether, alkylphenol formaldehyde condensation product polyoxyethylene groups ether, sulfonation castor-oil plant alkoxide, quaternary ammonium salt derivative, the condensation product of oxirane and nonyl or octyl phenol is main product or hydroxyl and the oxirane that does not dissociate by esterification, the alkalies and alkaline earth salt of sulfuric ester and sulfonic acid is as sulphonyl amber ester dinonyl and dioctyl sodium and such as the alkali of the macromolecule sulfonic acid derivative of sodium lignin sulfonate and calcium and carboxylate of the anhydrous sorbierite that the alkali salt condensation forms solubility etc.That can give an example has farming breast No. 2000 series, petroleum sodium sulfonate, dodecyl sodium sulfates, draws back powder, lauryl alcohol polyethylene glycol oxide base ether sulfonic acid sodium, tween series etc.
Mixture, inert carrier and the filler and one or more wetting agents and the dispersant that contain each active component in the wetting powder.Carrier is generally mineral inert substance such as potter's clay, kaolin, bentonite, talcum powder, diatomite etc.The wetting powder of the Herbicidal combinations of this invention contains the active component mixture of 0.5～90% (weight) (the more excellent 5-80% of being) usually, the dispersant of 0.25-25% (more excellent is 1～15%) (weight), inert solid carrier and the filler of 5-95% (weight) (more excellent is 5-80%).Form Herbicidal combinations jointly by them.
The suspending agent of this Herbicidal combinations is that water-soluble relatively poor active component is constantly stirred in water with emulsifier, dispersant, wetting agent etc., makes it evenly to disperse and suspend, so that spraying is used.Can suitably add thickener, antifreezing agent, defoamer etc. as required.Suitable suspending agent comprises the active component of 0.1～90% (weight) (more excellent is 0.5～60%).The upper limit is decided by the solubility limit of active component in solvent.
Missible oil is that the active ingredient with Herbicidal combinations is dissolved in as in a certain solvent in butanols, cyclohexanone, dimethyl formamide, dimethylbenzene or high boiling aromatic series or the hydro carbons, adds one or more emulsifier again and is prepared from.Active constituent content is approximately 0.1～90% (weight) in the missible oil, and more excellent is 5～80%.
Pulvis is through abrasive dust processing and make with active ingredient and fine grain dispergated solid matter such as talcum powder, natural clay and kaolin, bentonite, pyrophyllite or the diatomite of being.Pulvis contains effective composition and is approximately 0.1～50% (weight), and more excellent is 2～40%.
The preparation of granule is that active ingredient is sprayed at particulate inert material surface with absorption property or active ingredient is adhered to carrier mass surface or particulate inert material surfaces such as sand, kaolin with adhesives such as polyvinyl alcohol, Sodium Polyacrylate or mineral oil, also can the active ingredient that some is suitable be processed into granule with the method for common manufacturing granular fertilizer.Its active constituent content of dispersible granules agent (weight) between 5～90% in the water spreads fertilizer over the fields active constituent content (weight) between 1～50% in the granule, is preferably between 1～25%.
Following examples describe the present invention in detail.Embodiment mainly is for the present invention is described, but not is used for limiting the present invention.
Embodiment 1 is the formulation preparation example, and embodiment 2～8 is a biological Examples.
Embodiment 2～7 all adopts the cuvette that is of moderate size, and adds no grass-seed light loam 200g/ cup, and every kind of weeds are sowed 20～100, seed level 0.5～1cm, surperficial earthing.Medicine is sprayed in sowing one day after.Light application time 16 hours/day.20～30 ℃ of daytime temperature, night, temperature was 15～20 ℃. investigated various weeds fresh weights after the chemicals treatment in 20 days or 40 days.
Embodiment 8 is a field experiment, May 20 transplanting rice, the rice seedling length of time rice seedlings grow 5 leaf, 15 square metres of sub-district areas, plant medication in back 6 days, most weeds 0～1 leaves during medication adopt pesticide-clay mixture method dispenser (being about to spread fertilizer over the fields behind medicament and the 15kg sandy soil mixing in the dark rice field of 3～5cm water layer), investigate the fresh weight of various spontaneous weeds in every processing sub-district after the medication in 40 days.
Weeds preventive effect (%) is calculated as follows:
Weeds preventive effect (%)=(X-Y)/Y * 100
X: the weeds fresh weight of untreated control
Y: the weeds fresh weight after the chemicals treatment
Symphyogenetic differentiation is adopted fast and practical Colby method.If E is the expection weeds preventive effect of using with between compound (%), X, Y are respectively compound list time spent weeds preventive effects (%).Then:
When two kinds of compounds are used with: E=X+Y-XY/100
When three kinds of compounds are used with: E=(XY+XZ+YZ)/100
When surveying preventive effect, illustrate to have produced synergistic effect greater than expection preventive effect E.(" synergy of weeding composition and antagonism are calculated ", Weed 15,1967,20～22 pages) embodiment 1:
