RAJDHANI PETROCHEMICALS PRIVATE LIMITED, of 6B, Basement, Lalita complex, Opp, HDFC Bank, 352/3, Rasala Road, Navrangpura, Ahmedabad-380009, Gujarat, India

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION

The present disclosure generally relates to the field of herbicides. Particularly, the present disclosure provides a composition comprising a compound pinoxaden; in combination with chlorimuron ethyl or imazethapyr; and at least one additional herbicide compound for controlling weeds specifically for controlling weeds growing amongst crop plants.

BACKGROUND OF THE INVENTION
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art.

Various chemical compounds have been developed and used as herbicides for controlling different weeds growing along with crop plants and competing with them and thereby overtaking the crop plants in the field and resulting into loss for farmers. Success of controlling weeds depends upon various factors including mode of action, dose and rate of application of herbicide, specificity of herbicide in controlling particular weeds, mechanism of dissipation herbicide and other factors. To compensate the specificity of the herbicide to control only limited number of species of weeds, loss of herbicide due to dissipation and other such reasons, to improve the weedicide effect, different herbicides are applied simultaneously at much higher rates leading to antagonistic effect of different herbicides when applied together thereby resulting into ineffective weed control, resistance to such herbicides due to their continued application at much higher doses and harmful effects on crop plants leading to loss of crops in the field.

It is well known that some of the acetyl-CoA carboxylase (ACCase) inhibitors can function as herbicide. In particular, it is well known that some of the phenylpyrazole class of compounds possess ACCase inhibiting properties and hence, can function as herbicide. Among phenylpyrazole class, Pinoxaden is being investigated as a post-emergence herbicide for the control of annual grass weeds in cereal crops. However, compounds other than Pinoxaden, which fall under the phenylpyrazole class of compounds and which possess ACCase inhibiting properties are also under investigation. Likewise, compounds which do not fall under the phenylpyrazole class of compounds and which possess ACCase inhibiting properties are also under investigation.

It is well known that due to evolutionary process, the herbs may develop resistance against what was originally considered as a “lethal dose of herbicide”, in which case, the farmer may be forced to apply more amount of the herbicide to attain the same or lesser result. Application of herbicide which is greater than what was originally considered as “lethal dose of herbicide” has several disadvantages. Also, specific herbicides are tailor made taking into consideration specific type of crop and specific type of herb and does not provide wide-spectrum protection.

While it is a common belief that mixing different herbicides may be beneficial as compared to singular herbicide, there is no clear guideline as to: (a) what types of inhibitors / classes of compounds / specific compounds should be mixed, (b) in what proportions, the inhibitors / class of compounds / specific compounds should be mixed, (c) there is no guarantee that the intended purpose would be attained, wherein the intended purpose could be any of delaying development of resistance, reduction in quantity of dose which functions as the lethal dose, or a wide-spectrum control against many types of herbes, etc.

Therefore, attempts have been made to provide compositions comprising different herbicides to overcome one or more drawbacks mentioned above with the conventional manner of use of different herbicides together at higher rates. However, such attempts have not be successful in providing the effective composition comprising different herbicides. Thus, there still exists an unmet need in the art to provide compositions comprising different herbicides, wherein different herbicides comprised in the composition do not counteract each other’s action but provide synergistic effect, the composition is stable, can minimize or curtail toxic or harmful effect on crop plants, help in reducing the dose and rate of application and effective on array of different weeds.

Thus, there exists a need to develop additional combinations of herbicides which possesses at least one capacity to delay development of resistance, capacity to reduce quantity of dose which functions as the lethal dose, or capacity to act as a wide-spectrum control against many types of herbes, etc.

OBJECTS OF THE INVENTION

An object of the present invention is to provide a composition comprising combination of compounds having synergistic herbicidal effect.
Another object of the present invention is to provide a composition comprising herbicides, said composition being stable.

Yet another object of the present invention is to provide a composition comprising herbicide compounds for effective control of wide array of weeds.

The present invention relates to a composition comprising synergistic combination of herbicide compounds for effective control of wide array of weeds.

In one embodiment of the present invention there is provided a composition comprising a herbicide compound pinoxaden; in combination with chlorimuron ethyl or imazethapyr; and at least one additional herbicide compound for controlling wide array of weeds growing amongst crop plants.

The herbicide compound pinoxaden (8-(2,6-diethyl-p-tolyl)-1,2,4,5-tetrahydro-7-oxo-7H-pyrazolo [1,2-d] [1,4,5] oxadiazepin-9-yl 2,2-dimethyl propionate) used as one of the active ingredients in the composition of the present invention is a compound belonging to the phenylpyrazole class of chemical compounds. It is a post-emergence herbicide for the control of annual grass weeds in cereal crops. It’s herbicidal property is due to the inhibition of acetyl-CoA carboxylase (ACCase). It has the structure as per Formula I:

Formula I
The herbicide compound chlorimuron ethyl (2-([(4-chloro-6-methoxypyrimidine-2-yl)amino carbonyl]amino sulfonyl)benzoic acid, ethyl ester) is a member of the class of sulfonylurea. It is a pre and post- emergence herbicide that inhibits plant acetolactate synthase (ALS), an enzyme required for the biosynthesis of valine and isoleutine. It has the structure as per Formula II

Formula II

The herbicide compound imazethapyr (2-[4.5-dihydro-4-methyl-4-(1 -methylethyl)-5-oxo-lH-imidazol- 2-yl]-5-ethyl-3-pyridinecarboxylic acid) is a member of the class of imidazolinone. It is a herbicide that inhibits plant acetolactate synthase (ALS), an enzyme catalyzes the first common step in the biosynthesis of branched-chain amino acids: valine, leucine and isoleucine. This metabolic pathway plays an important role in plants. It has the structure as per Formula III.

Formula III

In one embodiment, the additional herbicide to be included in the composition in accordance with the present invention can be selected from the group consisting of but not limiting to fomesafen sodium, acifluorfen sodium, lactofen, bentazone, imazamox or imazethapyr.

Fomesafen sodium is an herbicide used for control of broadleaf weeds. Fomesafen products are formulated as the sodium salt and the concentration of the active ingredient in the formulation is expressed in terms of the acid equivalent (ae). Fomesafen sodium is in the diphenylether chemical class and it mode of action is via inhibition of protoporphyrinogen oxidase (PPO) in the plant.

Sodium acifluorfen is an herbicide for post-emergent weed control on agricultural crops and for residential spot treatment.

Lactofen is a broad spectrum pre and post emergence herbicide used for the control of broadleaf weeds.

Bentazone, is a post-emergence herbicide. The mode of action is based primarily on an irreversible blockage of the photosynthetic electron transport and in further consequence the inhibition of photosynthesis at photo system II.

Imazamox is used for control of most annual and perennial broadleaf weeds and grasses, woody species, and riparian and emergent aquatic weed species. Imazamox is a member of the imidazolinone class of herbicides.

The individual herbicides belonging to different class of chemicals are suitable for controlling limited species of weeds growing with only few crops like soybean, groundnut/Peanut, green gram, and few others. Surprisingly the composition comprising pinoxaden; in combination with chlorimuron ethyl or imazethapyr; and at least one additional herbicide selected from fomesafen sodium, acifluorfen sodium, lactofen, bentazone, imazamox or imazethapyr act synergistically that can control array of diverse weeds growing amongst large number of crop plants.

An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding is Clearfield® summer rape (canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®. which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt cotton (resistant to cotton boll weevil). Crops which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour). Other useful plants include turf grass for example in golf-courses, lawns, parks and roadsides, or grown commercially for sod, and ornamental plants such as flowers or bushes.

The composition in accordance with the present invention can be used to control harmful plants that are difficult to control and that sprout from rhizomes, rhizomes or other permanent organs.

The composition in accordance with the present invention can be used to control wide array of weeds in non-cultivated areas, on paths, track systems, industrial areas ("industrial weed control") or the like.

In another embodiment the composition can be used in known plant crops or tolerant crop plants which are still to be developed, are modified by conventional mutagenesis or are genetically modified for any property in comparison to previously occurring plants.

In another embodiment, the present disclosure relates to a method of controlling growth of undesired plants by application of a herbicidally effective amount of an composition of the present invention or formulation comprising the same.

In still another embodiment, the present disclosure relates to a method of preventing undesired plants from infecting crops by applying a herbicidally effective amount of the composition of the present invention or formulation comprising the same.

In yet another embodiment, the present disclosure relates to use of the composition of the present invention or formulation comprising the same on unwanted vegetation or plants.
In an embodiment the formulation of present invention may be present in the commercial form for example wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules using water for use are optionally diluted in the customary manner with water or other inert substance before use. The manner of use can include mixing the formulation together with water in the tank and the spray mixture, application before or after sowing, apply to the open furrow in which the seeds have been sown, seed dressing or treatment of the germinated seedlings.

In an embodiment the composition of the present invention as such or formulation comprising the same can be applied to the plants (for example harmful plants such as mono- or dicotyledon weeds or undesired crop plants), the seeds (for example grains, seeds or vegetative propagation organs such as tubers or shoot parts with buds) or the area on which the plants grow (for example the area under cultivation).

In an embodiment the composition of the present invention as such or formulation comprising the same can be applied in the pre-sowing (possibly also by incorporation into the soil), pre-emergence or post-emergence methods. Preference is given to use in the early post-sowing pre-emergence process or in the post-emergence process of plantation crops against harmful plants which have not yet emerged or have already emerged. The application can also be integrated into weed management systems, with shared multiple applications for example sequential applications.

In an embodiment, the composition or formulation in accordance with the present disclosure may be applied via tank mix method or sequential application. The composition may be used pre-emergence or post-emergence of undesired plants. It may be applied on the locus of the plant, including all plant parts, or on the soil or turf of growth. It may be applied before or after the crop seeds are planted.

In an embodiment, the composition lowers the application rate of active compounds on the undesired plants based on the formulation the way of application may be selected from spraying, dusting, scattering, soaking and the like.

In an embodiment, the composition or formulation comprising the same slows down the growth or kills the undesired plants. The herbicide compounds comprised in the composition in synergistic manner intervene the undesired plant's own metabolism and can thus be used to influence plant constituents in a targeted manner and to facilitate the harvest, e.g. by triggering desiccation and stunted growth. Furthermore, they are also suitable for general control and inhibition of undesirable vegetative growth without killing the plants, which can play an important role in many monocotyledonous and dicotyledon crops, as this can reduce or completely prevent storage.

The synergistic pesticide action of the inventive mixtures are demonstrated by the examples below. A synergistic effect exists wherever the action of a combination (ready-mix) or tank mix of active ingredient is greater than the sum of the action of each of the components alone. Therefore, a synergistically effective amount or an effective amount of a synergistic composition or combination is an amount that exhibits greater pesticide activity than the sum of the pesticide activities of the individual components.

In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S.R. in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” published in the journal Weeds, 1967, 15, p.20-22, incorporated herein by reference in its entirety. The action expected for a given combination of two or three active components can be calculated as follows:

Example 1:
A combination comprising Pinoxaden, Imazethapyr and Acifluorfen sodium in a ratio of 1:1.5:3 was prepared and its efficacy was tested against mixed weed flora in soybean crop in the following manner.
Crop : Soybean (Glycine max)
Target weeds : mixed weed flora (Grasses, broad leaf)
Number of Treatments: 11
Plot size : 6 m x 4 m=28 sq.m.
Application time :14 DAS (days after sowing), 2 to 4 leaf stage of weeds.
Application method : foliar spray with backpack sprayer attached flat fan nozzle.
Water volume : 400 liter per hectare
Observation Methods: Weed control (%): Species wise weed count recorded at 15 and 30 DAA (Days after Application) by using 0.25 m2 (50 cm x 50 cm) quadrant, treatment wise in minimum 5 places randomly selected in the plot. The species wise weed count further grouped into Grasses and Broad Leaf weeds (BLW) and sedges. The data presented here as total weed control (grasses+broad leaf+sedges). The average of each variable was used together with the sum of all the variables per plot to calculate the percentage of control.

Phytotoxicity: The observations on crop safety i.e., phytotoxicity or adverse effect of treatments were recorded at regular intervals. All the visual phytotoxicity symptoms like plant yellowing, leaf scorching, tip burning, bleaching, necrosis, stunting, crinkling, epinasty, hyponasty. Three leaves from each selected plant were scored using 0-10 rating scale, whereas 0=No injury/phytotoxicity, 1=1 to 10% phytotoxicity, 2=11 to 20%, 3=21 to 30%.......10=91 to 100% phytotoxicity. Percent phytotoxicity was determined using following formula.

Pod counts: Count the number of pods per plant from randomly selected 25 plants per plot at the time of harvest.
