Abstract

Disclosed herein is a A herbicidal combination comprising saflufenacil, Napropamide or Napropamide-M and a third herbicide.

Description

Technical Field:
The présent invention relates to a herbicidal combination for controlling undesirable plants. The présent invention more specifically relates to a synergistic combination of herbicides for controlling weeds.
Background and prior art:
Weeds are undesirable plants that can severely damage yield in crops. Farmers usually control these plants at the pre-plant stage as well as after sowing. Modem herbicides are used to either control or suppress these undesirable plants so as to allow sown crops a greater share of nutrient.
Current practipes include combining herbicides with varied modes of action, which allows broader spectrum of control and résistance management. However, the combinations currently known are not sufficient to control résistant and persistent weeds. Growers, increasingly face complex weed situations that may not be controlled with just one herbicide. There is always a need in the art for improved herbicidal combinations with enhanced weed control efficacy.
PPO inhibitor herbicides are mostly used to injure broadleaf plants and hâve some activity on grasses. They hâve a limited translocation in plants and are used to control weeds in field crops, vegetables, tree fruits and vines, small fruits, nurseries, lawns, etc. PPO inhibitors usually burn plant tissues within hours or days of exposure, making them an excellent tool to control unwanted weeds both pre and post emergent.
Saflufenacil is PPO inhibitor herbicide that is used for both pre-plant burndown as i !
well as post emergent control of weeds. Combination of Saflufenacil with other broad spectrum herbicides are known from WO2016113334 (Massa et.al) or US2013244876 (Thorsten et.al). Massa et al teach a combination comprising saflufenacil, glufosinate and a third herbicide selected from metribuzin, S metolachlor, flumioxazin, clodinafop or clethodim. Thorsten et al teach a combination comprising saflufenacil and ethephon or cyclanilide.
Very long chain fatty acid inhibitors are sélective herbicides that prevent root cell élongation. These herbicides act systemically by being absorbed through roots and then translocated. These herbicides are generally applied pre-emergent to control a range of weeds including annual grasses and some broadleaf weeds in several crops such as in vegetables, vines, bushes, sunflower, tobacco, ornamentals etc. Absorbed by |roots and shoots, these herbicides cause cell damage and are an excellent tool to control both pre -emergent weeds. Napropamide and/or Napropamide-M are examples of very long chain fatty acid inhibitor herbicides, which is used pre-emergent for control of broadleaf and annual grasses. Napropamide is known to be used in combination such as those known from JP 2016-88913 A (Nakamura, Arata et.al) teach combinations of PPO inhibitors with very long chain fatty acid inhibitors and a plant activator for turf. US9307765 B2 (Shroff et.al.) teach combinations of Napropamid-M with various other herbicides. However, prior art does not teach the use of spécifie PPO inhibitors and spécifie very long chain fatty acid inhibitors with additional spécifie herbicides for the yet better control of weeds in agricultural lands.
A combination of herbicides may not always resuit in the desired effect. Combination of herbicides may lead to an additive effect or an antagonistic effect. It may also resuit in phytotoxicityto the crops making it an undesirable combination. Agronomists must therefore, carefully select the herbicides that can be combined to offer a synergistic effect that would control weeds while having no phytotoxic effect on the cLp, and reduce the chances of development of herbicide résistant weeds.
Protection of planted crops from undesirable plants which inhibit crop growth is a perpétuai struggle for ail farmers. Herbicides hâve been used to control growth of such plants. There are many herbicides and combinations known in the art. There still remains a need for improved herbicidal combinations that can effectively control weeds thereby improving yield and plant health, with reduced phytotoxicity.
Saflufenacil is a PPO inhibitor herbicide. Its Chemical name is A/'-{2-chloro-4-fluoro5-[1,2,3,6-tetrahydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)pyrimidin-1yl]benzoyl}-A/-isopropyl-A/-methylsulfamide.
Napropamide and its isomer Napropamide-M are very long chain fatty acid inhibitor herbicides. Their Chemical names are (RS)-N,N-diethyl-2-(1naphthyloxy)propionamide and (R)-N,N-diethyl-2-(1-naphthyloxy)propionamide respectively.
Saflufenacil alone is usually effective for control of early season broadleaf weed control. However, its weed control efficacy reduced beyond 30 days after treatment. The use of a combination of herbicides with spécifie modes of action may leave other weeds completely untouched. There is therefore, a need in the art, for an herbicidal combination which offers a broader and more complété spectrum of weed control, which can give a better control of weeds at lower use rates, and which gives good residual control.
There is therefore a need in the art for combinations that hâve advantageous properties such as a herbicidal combination that is synergistic, helps in résistance management, reduces dosage of herbicides used thus causing minimal damage to the environment, or a herbicidal combination that has excellent residual effects.
Embodiments, of the prJsent invention may therefore ameliorate one or more oi the above mentioned problems:
i !
Objects ofthe invention:
Therefore, one object of the présent invention is to provide a synergistic herbicidal combination comprising saflufenacil wherein the weed control efficacy of saflufenacil does not reduce with continued usage.
Another object of the présent invention is to provide a synergistic herbicidal combination comprising saflufenacil wherein the weed control efficacy of saflufenacil does not reduce for at least 30 days after treatment.
Yet another object of the présent invention is to provide a synergistic herbicidal combination icomprising saflufenacil wherein the weed control efficacy of saflufenacil does not reduce with continued usage.
Another objept of the présent invention is to provide a synergistic herbicidal combination which offers a broaderand more complété spectrum of weed control.
Another object of the présent invention is to provide a synergistic herbicidal combination which provides a better control of weeds at lower use rates, and which gives good residual control.

The term herbicide, as used herein, shall mean an active ingrédient that kills, Controls or otherwise adversely modifies the growth of undesirable plants. As used herein, a herbicidally effective or végétation controlling amount is an amount of active ingrédient that causes a “herbicidal effect,” i.e., an adversely modifying effect and includes déviations from natural development, killing, régulation, desiccation, retardation. Tthe terms “plants” and “végétation” include, but are not limited to, germinant seeds, emerging seedlings, plants emerging from végétative propagules, and established végétation. The term “locus” as used herein shall dénoté the vipinity of a desired crop in which weed control, typically sélective weed control is desired. The locus includes the vicinity of desired crop plants wherein the weed infestation has either emerged or is yet to emerge. The term crop shall include a multitude of desired crop plants or an individual crop plant growing at a locus.

Thus, in anotfier aspect, the présent invention provides a method of controlling weeds at a locus, said method comprising applying a composition comprising saflufenacil, napropamide or napropamide-M and a third herbicide and at least one agrochemically acceptable excipient.
Surprisingly, it has been found by the présent inventors that saflufenacil, 5 napropamide or napropamide-M, and a third herbicide when applied individually, was ineffective in the control of weeds, but demonstrated excellent synergistic control on weeds when applied together. The combination controlled the weed both pre and post emergently. The combination of saflufenacil, napropamide or napropamide-M and a third herbicide synergistically controlled broadleaf weeds, 10 sedges, and grasses a particular locus. The current invention therefore provides advantageous methods of controlling weeds both pre and post emergently. The présent method also provides a broader spectrum of controlling weeds that helps in résistance management, thus preventing the weed from becoming résistant to either of the herbicides whist providing a broader spectrum of control at lower use 15 rates.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, 20 combinations, and équivalents ofthe spécifie embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by ail embodiments and methods within the scope and spirit of the invention.
Examples:
Trials were carried out for evaluating the herbicidal mixtures of the invention on different weeds. The percentage control was calculated from the observed percent weed coverage data after 20 DAA and 30DAA. The results were tabulated as i hereunder: ।

Conclusion: It was thus found that the efficacy of saflufenacil and Napropamide combination was very poor initially. The addition of a third herbicide e.g. metribuzin surprising restored the efficacy of an otherwise poor combination to acceptable 5 levels. The addition of a third herbicide was found surprisingly bénéficiai jto an otherwise ineffective combination.
