Abstract

Control of weeds in a rice crop is obtained by applying to the crop, the weeds, or the locus of either or both, a herbicidal composition containing molinate and acetochlor in a weight ratio of from about 250:1.5 to about 5:1.

Description

Synergistic herbicide compositions
Background of invention and prior art
The present invention relates to Synergistic herbicide compositions, especially for the composition of preventing and kill off the weeds in the rice crops.
Molinate (S-ethyl six hydrogen-1H-azatropylidene-1-carbothioic acid ester) is a kind of weed killer herbicide of thiocarbamates, is used for preventing and kill off the weeds of rice crops for many years always, and common production marketing with trade mark ORDRAM .It has different formulations and concentration, and molinate is before plantation, before the flood irrigation or use after the flood irrigation, can prevent and kill off the weeds in the rice crops of wide spectrum scope.General amount of application is about 500 to about 11000g/ha.Yet,, wish under using, promptly can realize weed control than the situation of low dosage molinate as many agricultural chemicals.This also causes less influencing the workman of environment and/or converted products.
Have surprisingly been found that now more a spot of weed killer herbicide Acetochlor and molinate combination can produce synergistic effect, so that use molinate a small amount of and/or amount of application promptly can obtain same weed control efficacy.
Acetochlor (be 2-chloro-2 '-methyl-6 '-ethyl-N (ethoxymethyl) antifebrin) be the weed killer herbicide of a kind of acetamide or halogenated acetanilide being class, with several trade (brand) names, particularly SURPASS  and HARNESS  sell, and with trade mark such as TOPNOTCH TMAnd FULTIME TMThe microencapsulated formulation of selling.This weed killer herbicide is mainly sold as corn herbicide, and known it also can be used for some other crop such as soybean.Yet it is too big and can not be as preventing and kill off the main weed killer herbicide of the weeds in the rice crops to the poisoning of rice that Acetochlor is considered to usually.But, to Acetochlor and the molinate that rice crops does not produce the poisoning amount basically be used in combination according to the present invention, when especially using with the amount of application little or lower than conventional usage amount, can produce synergistic effect, the result uses before flood irrigation or after the flood irrigation all to obtain the good preventive effect to weeds in the rice crops.
Summary of the invention
The present invention includes a kind of Herbicidal combinations and prevent and kill off method for weed in the rice crops.
On the one hand, the present invention relates to contain the Synergistic herbicide compositions of molinate and Acetochlor.
Second aspect, it comprises the Synergistic herbicide compositions that contains molinate and Acetochlor, both were respectively about 250: 1.5 to about 5: 1 by weight.
On the other hand, the present invention relates to a kind of method for weed of preventing and kill off in the rice crops, this method comprises and will contain the synergistic composition of molinate and Acetochlor, and particularly both weight ratios are respectively and were applied to described crop, described weeds or they separately or common growth place to about 5: 1 composition in about 250: 1.5.
The present invention describes in detail
The present invention relates to use the Herbicidal combinations of molinate and Acetochlor to prevent and kill off the purposes of weeds in the rice crops.Within the scope of the present invention, said composition shows synergistic effect, and two kinds of weed killer herbicides of promptly this effect and this are prevented and kill off identical weeds separately under similar condition effect is compared, and is exceed people unexpected.
According to the present invention, the weed killer herbicide molinate of available herbicidally effective amount and Acetochlor synergistic composition in the presence of rice crops, handle crop, weeds or they separately or common growth place come management of weeds.In general, we find when two kinds of weed killer herbicides be respectively by weight about 250: 1.5 to about 5: 1, preferred about 250: 3.25 to about 12: 1, show synergistic effect when most preferably from about making up in 36: 1 to about 12: 1.Yet we find for molinate and Acetochlor synergistic effect between the two, not necessity limit these two kinds of herbicidal compositions must be within these weight ratio scopes, because under other weight ratio condition, also may have synergistic effect.
In the time of when be administered to the rice thing of cultivating by different way in the different time on, said composition all can produce synergistic effect or obtain beyond thought preventive effect to weeds in the rice crops.For management of weeds, said composition can be before plantation, the plantation back but before flood irrigation (before the flood irrigation, behind the seedling) or rice crops emerge and flood irrigation after (after the flood irrigation, behind the seedling) use, and can on Direct-seeding Rice or transplanting rice, use.
For using composition, needn't require these two kinds of weed killer herbicides of molinate and Acetochlor to use, perhaps even need not use simultaneously with the form of physical mixed.No matter when they use, as long as two kinds of weed killer herbicides exist simultaneously in the rice crops and just can produce the combination synergistic effect.Therefore, for example can use the physical composition of two kinds of weed killer herbicides, perhaps also can a kind ofly use earlier than another kind.For example, one of two kinds of weed killer herbicides are used with sustained release formulation such as microencapsulated formulation before seed rice is planted, and another kind is used with the liquid or solid formulation of routine subsequently; As long as when second kind of herbicide application, the weed killer herbicide of using earlier also is present in the soil, as long as and the weight ratio of weed killer herbicide that can bring into play drug effect in the open and claimed scope of the present invention.
Therefore, weed killer herbicide not only can the liquid or solid form be used, and can produce the combination product of the liquid or solid form that contains two kinds of weed killer herbicides.Typical liquid preparation comprises emulsion, suspending agent (comprising the suspending agent that contains microcapsules), solution, missible oil and the preparation that can flow.The form that solid product comprises has granule, wetting powder, water dispersible solid product (comprising the water dispersible granule that contains the microencapsulation agricultural chemicals) or pulvis.Except active weedicide, the liquid of composition and solid type generally also contain other composition such as solvent, wetting agent, suspension aids, anti-caking agent, dispersant, emulsifier, antifreezing agent, defoamer and other additive.
One of weed killer herbicide or both can be prepared into the controlled release composition of various form known and be used.Such composition can make active ingredient relatively lentamente or sustained release in environment, comprise as capsule, microcapsule formulations and various forms of sustained release granula.
Can contain these two kinds of weed killer herbicides that exist with multiple different physical form according to combination product of the present invention or composition.In some cases, combination product can mix (" bucket mix ") by simple physics and produce the commercially available product that contains described active weedicide, as two kinds of missible oil of weed killer herbicide as described in containing, as long as all the components of two kinds of products is compatible relatively.Alternatively, can a kind of packing of produce and market, as a whole, it comprises and places separately these two kinds of weed killer herbicides of container, but packaging together, generally is called " two packed ".Two packed Herbicidal combinations of the present invention that are particularly suitable for, because the amount than Acetochlor is many basically for the amount of molinate, do the as a whole packing of product so can produce, comprising bigger bulk container that contains molinate weed killer herbicide product and the relative little bulk container that contains Acetochlor weed killer herbicide product.
Alternatively, can produce the previously prepared composition (" pre-composition ") that contains these two kinds of weed killer herbicides.Because Acetochlor and molinate are liquid under usual conditions, so fluid composition is preferred often.Typical fluid composition comprises the missible oil that contains two kinds of weed killer herbicides, and two-phase emulsion (or microemulsion), and wherein each contains a kind of weed killer herbicide mutually.A kind of premixed liquid body preparation that typically contains these two kinds of weed killer herbicides is a missible oil, contain just like 900g/L molinate and 25g/L or 37.5g/L Acetochlor, with kerosene make solvent and comprise the Sponto217 of 1.50 percentage by weights and the Sponto 221ER of 3.50 percentage by weights as emulsifier.The Sponto product is the emulsifier that contains the blend of the nonyl phenol of ethoxylation and calcium dodecyl benzene sulfonate.
Yet two kinds of weed killer herbicides also can be sold by solid pharmaceutical preparation usually in the middle of the practical application, i.e. impregnated granules agent can be produced the solid product such as the impregnated granules agent that contain these two kinds of weed killer herbicides thus similarly.Solid pharmaceutical preparation such as the wetting powder or the pulvis that can prepare similarly, other.
In addition, utilize appropriate ingredients and condition, can also prepare the microencapsulation product, wherein one or both weed killer herbicides are enclosed in the microcapsules, and described microencapsulation product can liquid form (being capsule suspension) or solid form (i.e. the water-dispersible granules of producing by dry micro-capsule suspension) sale.One type of liquid agent shape can be micro-capsule suspension, and wherein a kind of weed killer herbicide is enclosed in the capsule, and another kind is present in the continuous liquid phase with non-encapsulated form.Another kind of type is the suspending agent that contains encapsulated molinate of difference and Acetochlor.Contain the preparation of these two kinds of weed killer herbicides or types of compositions and be not restricted to cited those in the present disclosure, because for the preparation of other type, those skilled in the art is easy to expect.
Composition management of weeds with molinate and Acetochlor can be illustrated by following examples:
Using of the composition of embodiment 1 present embodiment simulation molinate and Acetochlor on the Direct-seeding Rice of cultivating under the condition of typical America.Seedling after-stage and barnyard grass grass are in 2 leaves during the phase before filling, with the composition of molinate and Acetochlor in the greenhouse with the amount of application shown in the table 1 (the gram numerical table of using one or both weed killer herbicides with per hectare shows), be administered to comprise rice ( Red rice, the Katy kind) and the barnyard grass grass ( Echinochloa crusgalli ECHCG) and difformed galingale herb ( Cyperus DifformisCYPDI) on the level land.Treat that weeds are long separately to 2 leaf after dates, be transplanted in the rice crops.Result of the test as follows face table 1 (comparing to does not have the contrast plot of handling, to prevent and kill off or the percentage of poisoning is represented.100% expression is prevented and kill off fully; 0% expression does not have effect).
