Description

A kind of Synergistic herbicide compositions

Technical field

The present invention relates to a kind of Herbicidal combinations, particularly relate to a kind of Synergistic herbicide compositions.

Background technology

In recent years the direction of pesticide developing be embody efficiently, low toxicity, low-residual and pollution-free.It is embodied in pursuit " three high ", it may be assumed that safety is high, and it is low that this does not require nothing more than toxicity, remains low, and nuisanceless；Biological activity is high；Selectivity is high.Therefore continue to improve the performance of current Pesticidal products, reach efficiently, low toxicity, free of contamination requirement.

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 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, sends Roc herbicide sulfone and 2 first 4 chlorine and derivant thereof collectively or individually to be applied to undesirable plant or its growth place by the active component of the Synergistic herbicide compositions of the present invention.

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.

The active component that the Synergistic herbicide compositions of the present invention comprises effective dose sends Roc herbicide sulfone and 2 first 4 chlorine and derivant thereof to have synergistic function.When administration of active ingredients can be observed synergism when sending Roc herbicide sulfone and 2 first 4 chlorine and derivant (such as common preparation or as tank mix) thereof together；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 and send Roc herbicide sulfone and 2 first 4 chlorine and derivants thereof, 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.
