Description
Technical field
The present invention relates to a kind of Synergistic herbicide compositions.The invention still further relates to a kind of growing method preventing and treating undesirable plant.
Background technology
In plant husbandry, preventing and treating suppression plant growth to cause weeds that yield reduces and cover crop be critically important.In order to reduce the loss caused due to the weeds in arable farming, as growth difference or crop yield reduce, have now been developed that some can effectively prevent and treat described weeds and the herbicidal active component to crop safety.Up to the present, there is the herbicide developed in a large number registered and for preventing and treating the weeds of some crop.Sufficiently high activity of weeding and a wide herbicidal spectrum should be had for preventing and treating the herbicide of the weeds in specific arable farming, and response environment and crop safe enough.But, not every herbicide can fully meet above-mentioned requirements.
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.So, 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.
The combined administration of some different herbicide with specific effect known may cause the activity of herbicide components to be improved compared with simple addition.This activity improves also referred to as synergistic function or Synergistic active.Therefore the rate of application of weeding active compound needed for preventing and treating noxious plant can be reduced.
Bensulfuron-methyl (Bensulfuron-methyl), Chinese name cry again Nongdeshi or rice without grass, chemical name: 2-{ ((4,6-dimethoxypyridin-2-base) amino carbonyl nitrilo] sulfonvlmethvl) essence of Niobe；Chemical structural formula is:

The Synergistic herbicide compositions of the present invention can be used in a usual manner by using technology well known to those skilled in the art.Suitably technology includes spraying, atomization, dusting, broadcasts sowing or water.Use type and depend on desired purpose in a well-known manner；Under any circumstance this technology is it is ensured that the most possible of inventive compound is distributed.
The present invention provides a kind of method preventing and treating undesirable plant growing, including: (i) before undesirable plant germination (before bud)；(ii), after undesirable plant germination (after bud), or (iii) (i) and (ii) time, the Synergistic herbicide compositions of the present invention of herbicidally effective amount is applied to undesirable plant or its growth place.
If the active component of the Synergistic herbicide compositions of the present invention being applied to soil surface before germinateing, then it is entirely prevented from weeds seedling and germinates, or weed growth is to cotyledon period, but then it just stops growing, and final the most dead after two thoughtful surroundings.
If after germination described active component to be applied to the green parts of plant, growth the most drastically can stop in the extremely short time after treatment equally, and the trophophase that this ruderal plant is when being maintained at time of application point, or it is the most dead after some time, thus early and eliminate the competition useful crop produced by undesirable plant constantly with pole in this way.
A kind of method preventing and treating undesirable plant growing, by active component bensulfuron-methyl or the pyrazosulfuron of the Synergistic herbicide compositions of the present invention, sends Roc herbicide sulfone, mefenacet collectively or individually to be applied to undesirable plant or its growth place.
Described reactive compound can be applied to undesirable plant (such as noxious plant, such as unifacial leaf or dicotyledonous broad leaved weed, grassy weed, sedge or undesired crop plants), seed (such as caryopsis, seed or asexual propagation organ, the branch portion of such as tuber or band bud) or growth place (such as soil), preferably be applied to green plants and plant parts and, if appropriate, soil additionally it is applied to.
Active component bensulfuron-methyl or pyrazosulfuron that the Synergistic herbicide compositions of the present invention comprises effective dose, Roc herbicide sulfone, mefenacet is sent to have synergistic function.When administration of active ingredients bensulfuron-methyl or pyrazosulfuron together, send Roc herbicide sulfone, mefenacet (such as common preparation or as tank mix) time synergism be can be observed；When using reactive compound (using respectively) in the different time, it is possible to observe synergism.Can also many parts use described herbicide or Synergistic herbicide compositions (sequential application), such as use before first bud and then use after bud, or use after bud the most in early days, then use after mid-term or later stage bud.The most jointly or the most simultaneously use described active compound bensulfuron-methyl or pyrazosulfuron, send Roc herbicide sulfone, mefenacet, and particularly preferably jointly use.A kind of possible use is that the form with tank mix uses described reactive compound jointly, is wherein mixed in groove together with water by the concentrate formulation of the optimal preparation of each reactive compound, then uses gained flushing liquor.
When active component bensulfuron-methyl or pyrazosulfuron, send Roc herbicide sulfone, mefenacet jointly to be used time, there is synergistic function.Here, the activity of described Synergistic herbicide compositions is higher than the expection summation of each herbicidal activity used.Synergism makes rate of application to reduce, preventing and treating the broad leaved weed of more wide range, grassy weed and sedge, herbicide effect onset is faster, the persistent period is longer, preferably prevent and treat and can widen the phase of using by only once or several times using just to have undesirable plant.Active component bensulfuron-methyl or pyrazosulfuron in described Synergistic herbicide compositions, send Roc herbicide sulfone, the effective dose of mefenacet is all adjustable to relatively low level, so that its effect as little as optimum degree to soil.This makes it first be possible not only to be applied to sensitive crop, the most almost avoids underground water pollution.Needed for the Synergistic herbicide compositions of the present invention makes active component, rate of application significantly decreases.
A kind of method controlling undesirable plant growing, uses in the presence of other reproductive part of plant, the seed of useful crop or the useful crop of useful crop including by the Synergistic herbicide compositions of the present invention.
If active component can not be well tolerable by some crops, then can be by spraying apparatus directed spraying Herbicidal combinations so that they the most tactiosensible crops when reaching to be grown in the following leaf being not intended to plant or exposed soil.
The method of the infringement that other reproductive part of plant, the seed of useful crop or useful crop that the present invention also provides for a kind of useful crop reducing or preventing and send Roc herbicide sulfone to processing with it are caused, including other reproductive part with the plant of useful plant, the seed of useful crop or useful crop described in Synergistic herbicide compositions of the present invention process.Bensulfuron-methyl of the present invention or pyrazosulfuron, send Roc herbicide sulfone, the combination of mefenacet, improve the compatibility sending Roc herbicide sulfone with crops.
The rate of application sending Roc herbicide sulfone can change in a wide range, such as at 0.1-1000g/ha, and preferably 5-500g/ha, more preferably 10-300g/ha.When prior to seeding, plantation before or bud before and bud after use send Roc herbicide sulfone time, it can prevent and treat the noxious plant of relatively wide spectrum, the most annual unifacial leaf or dicotyledonous broad leaved weed, grassy weed and sedge, and undesired crop plants.
The rate of application of bensulfuron-methyl or pyrazosulfuron can change in a wide range, such as 1g-500g/ha, in the range of preferably 1-200g/ha, preferably 2-100g/ha, particularly preferably 3-50g/ha.
The rate of application of mefenacet can change in a wide range, such as 1g-1000g/ha, preferably 5-800g/ha, preferably 2-500g/ha.
For the Synergistic herbicide compositions of the present invention, rate of application is the most relatively low, such as in the range of 1-500g/ha, preferably 2-300g/ha, particularly preferably 5-200g/ha.
