Description
Technical field
The present invention relates to a kind of Synergistic herbicide compositions and the method preventing and treating undesirable plant growing thereof.
Background technology
Crops cause crop yield to reduce due to Weed infestation, are required to use substantial amounts of herbicide for this every year and carry out weed control to retrieve crop yield loss.In recent years, weeds are increasingly severe to the harm on crops, and due to the abuse of herbicide, cause weeds that pesticide is produced increasing resistance, cause weed control efficacy to reduce year by year.
Most-often used increase activity of weeding is that two or more have the herbicidal active compounds mixing of different activity of weeding with the method for the herbicidal spectrum widening existing herbicide.If mixing two or more herbicidal active compounds, the herbicide action outstanding than single herbicide application may be demonstrated.When the effect of the mixture of two or more composition is more than the expection effort levels of each composition, we term it " potentiation ".But, present in the Herbicidal mixture of the two or multiple herbicidal active compounds, potentiation is the most visible.Due to the difference of the aspects such as herbicidal performance, absorbance, transfer, metabolism, the activity of weeding of most of mixture is singly executed less than each composition." antagonism " represents the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds singly executing less than each composition." addition " represents that the such situation i.e. herbicide action of the mixture of two or more herbicidal active compounds is identical with singly executing of each composition.
Send Roc herbicide sulfone (Pyroxasulfone); chemical name is: 3-[5-(difluoro-methoxy)-1-methyl-3-(trifluoromethyl) pyrazoles-4-ylmethyl sulfonyl]-4,5-dihydro-5,5-dimethyl-1; 2-azoles, chemical structural formula is:
Roc herbicide sulfone is sent to have been described in EP1364946 and US20050256004.Sending Roc herbicide sulfone is highly effective pre-emergent herbicide, but after Seedling, activity is poor.Send Roc herbicide sulfone when being applied to some dicotyledonous crops such as Cotton Gossypii, Helianthi, Semen sojae atricolor, Btassica (brassica) crop, during such as card Nola (canola) and Brassica campestris L and some gramineous crop such as rice, Semen Tritici aestivi, rye (Secale cereale L.) and Fructus Hordei Vulgaris, crops sustain damage with unacceptable degree.

Biology test case
Evaluation to the mixed potentiation executing middle display of two or more herbicidal active component is based on " CalculationSynergistic
And Antagonistic Response of Herbicide Combinations " Colby ' s method described in (Weeds 15/1 (1967), S.R.Colby) determines.
Shown in computing formula such as following formula (1)
……………………………………(1)
In formula (1), X represents herbicide A control of weeds (%) under Xg effective ingredient/ha consumption,
Y represents herbicide B control of weeds (%) under Yg effective ingredient/ha consumption,
E0 represents the expection control of weeds (%) under X+Yg effective ingredient/ha consumption.
If the actual control of weeds rate observed in biologic test exceedes the use calculated desired value of Colby ' s method (E0), then it represents that the effect of Herbicidal combinations is more than the summation of each agent effectiveness, it means that compositions has potentiation.
Test before Seedling:
Under greenhouse experiment, unifacial leaf and the seed of dicots ruderal plant or rhizome are placed in equipped with covering in the alms bowl of dauk and with soil.Use standard soil as cultivation matrix.In the Seedling last stage, herbicide individually or is as a mixture administered to soil surface.After process, alms bowl is placed in greenhouse and is held under the excellent growing conditions being suitable to weeds.By compared with untreated matched group, the infringement of emerging after emerging the plant damage after the test period in 3-4 week or test plants carries out visual assessment.Shown in test result, the Synergistic herbicide compositions of the present invention illustrates the best activity of weeding before emerging to broad-spectrum weeding.Testing viewed numerical value to show, under suitable low dosage, the effect of the Synergistic herbicide compositions of the present invention has exceeded the desired value according to Colby, shows obvious potentiation.
Test after Seedling
Use potted plant stem and leaf facture (NY/T 1155.4-2006): the built-in quantitative soil of polypots at high 6cm, diameter 9cm, 15 ~ 20, the seed of unifacial leaf and dicots weeds is sowed in polypots, temperature indoor cultivation it is placed on after the fine earth that lid 0.5 ~ 1cm is thick, treat that weeds length carries out stem and leaf spraying treatment to 2 ~ 4 leaf phases, every alms bowl spraying liquid 1mL, often process and be repeated 4 times, and set the process without medicament as compareing.Process is placed on temperature indoor cultivation, the growing state of routine observation target weeds, estimates target damage symptoms and growth inhibited situation, and claims aerial parts fresh weight or strain fresh weight, evaluate the medicament toxicity action to target weeds with target fresh weight inhibition after 21d.
Three kinds of reagent are prepared: 1, send Roc herbicide sulfone according to constant weight percentage ratio；2, mefenacet；3, Roc herbicide sulfone+mefenacet is sent.Afterwards by above-mentioned each reagent dilute with water, it is thus achieved that medicament diluent.
Investigation method:
Test estimates target damage symptoms and growth inhibited situation after processing 21d, and claims aerial parts fresh weight, calculates fresh weight inhibition (%).
To the evaluation of the mixed potentiation executing middle display of two kinds of herbicidal active components based on Colby ' s formula.
If the actual control of weeds rate (E) observed in biologic test exceedes the use calculated desired value of Colby ' s method (E0), then represent the effect summation more than each agent effectiveness of Herbicidal combinations, it means that compositions has potentiation.
The Synergistic herbicide compositions of the present invention is tested for the important noxious plant (grassy weed, broad leaved weed, sedge weed) of following wide spectrum: rice barnyard grass (Echinochloa oryzicola), Herba Digitariae (Digitaria
Spp.) Herba stellariae mediae (Stellaria media), Amaranthus retroflexus (Amaranthus retroflexus), volume stem knotweed (Fallopia (ex
Polygonum) Convolvulus), Herba Abutili (Abuthilon
Theophrasti), Sagittaria trifolia L. Var. Angusti-folia(Sieb.) Kitag.(Sagittaria sagittifolia L.) (Sagittariatrifolia), Rhizoma Alismatis (Oriental Waterplantain Rhizome), Herba monochoriae vaginalis (Herb of Pygmy Arrowhead), Monochoria korsakowii (Monochoria
Korsakowii), Lindernia procumbens (Krock.) Phillcox. (Lindernia procumbens), Herba Solani Nigri (Solanum nigrum L.), firefly Lin (Scirpus
Juncoides Roxb), Herba Cyperi Difformis (Cyperus difformis L.), Herba chenopodii (Chenopodium alum L.), wild oat (Avena
Fatua L.), Herba Galii Teneri (Galium aparine L. var. tenerum
Gren.et (Godr.) Rebb.。
Result of the test shows: sends Roc herbicide sulfone and mefenacet in the range of 50:1-1:100, prevents and kill off grassy weed, broad leaved weed, sedge weed show obvious potentiation.
The Synergistic herbicide compositions of the present invention, preventive effect is better than activity when each component is administered alone, the test of pesticide effectiveness verifies that a combination thereof has potentiation, expand control of weeds spectrum, crop field grass family, broad leaved weed and sedge weed are prevented and kill off in a dispenser, reduce spraying times, reduce cost accounting, slow down the generation of Weed Resistance, good to crop safety, meet the security requirement of pesticidal preparations.Weeding or postemergence weed control is closed before can be used for corn and soybean, corn, Helianthi, Rhizoma Solani tuber osi, Semen arachidis hypogaeae, Cotton Fields Seedling.
Safety effect
Under greenhouse experiment, test plant wheat seed is planted in plastic tank, plastic tank grows to the 4-leaf phase.In this stage, will send Roc herbicide sulfone, mefenacet, send the compositions of Roc herbicide sulfone+mefenacet, be administered to test plant.After using 3 weeks, percentage rate is used to measure the evaluation herbicide phytotoxicity to crop.100% represents that test plant is the most dead, and 0% represents plant-less toxicity effect.
Can be seen that, mefenacet and the combination sending Roc herbicide sulfone, improve the compatibility sending Roc herbicide sulfone and crops, reduce or prevent the infringement that other reproductive part of plant, the seed of useful crop or useful crop of the useful crop sending Roc herbicide sulfone to processing with it are caused.
