The oxadiazole compounds reported in the above literature have disadvantages in certain aspects, such as that they exhibit a narrow spectrum of application or that they do not have satisfactory fungicidal activity, particularly at low application rates.

Therefore, it is an object of the present invention to provide cmnpounds having an improved/enhanced activity and/or a broader activity spectrum against phytopathogenic fungi.

This objective is achieved by using a compound of formula (I) of the present invention for controlling or preventing phytopathogenic fungi.

SOMMARYOF THE INVENTION:

The present invention relates to a compound of formula (I),

wherein, R1, L1,,A k, L2, W, L4, R5, R8 and R9 are as defined in the detailed description. The present invention also relates to a process for preparing the compound of formula (I).

The compounds of formula (I) have been found to be advantageous over the compounds reported in the literature in either of improved fungicidal efficacy, broader spectrum of biological activity, lower application rates, more favourable biological or environmental properties, or enhanced plant compatibility.

The present invention further relates to a combination comprising the compound of formula (I) of the present invention and at least one further pesticidally active substance for effectively controlling or preventing phytopathogenic fungi which are difficult to combat.

The present invention still further relates to a composition comprising the compound of formula (I) or the compound of formula (I) in combination with a further pesticidally active substance.

The present invention still further relates to a method and use of the compound of formula (I), the combination or the composition thereof for controlling and or preventing plant diseases, particularly phtopathogenic fungi.

DETAILED DESCRIPTION OF THE INVENTION:

DEFINITIONS:

The definitions provided herein for the terminologies used in the present disclosure are for illustrative purpose only and in no manner limit the scope of the present invention disclosed in the present disclosure.

As used herein, the terms “comprises”, “comprising”, “includes”, “including”, “has”, “having”, “contains”,“containing”,“characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method.

The transitional phrase“consisting of’ excludes any element, step or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase“consisting of’ appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

The transitional phrase“consisting essentially of’ is used to define a composition or method that includes materials, steps, features, components or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term“consisting essentially of’ occupies a middle ground between“comprising” and“consisting of’.

Further, unless expressly stated to the contrary,“or” refers to an inclusive“or” and not to an exclusive “or”. For example, a condition A“or” B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

Also, the indefinite articles“a” and“an” preceding an element or component of the present invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore“a” or“an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular.

As referred to in this disclosure, the term“invertebrate pest” includes arthropods, gastropods and nematodes, helminths of economic importance as pests. The term“arthropod” includes insects, mites, spiders, scorpions, centipedes, millipedes, pill bugs and symphylans. The term“gastropod” includes snails, slugs and other Stylommatophora. The term“nematode” refers to a living organism of the Phylum Nematoda. The term "helminths” includes roundworms, heartworms, phytophagous nematodes (Nematoda), flukes (Tematoda), acanthocephala and tapeworms (Cestoda).

In the context of this disclosure“invertebrate pest control” means inhibition of invertebrate pest development (including mortality, feeding reduction, and/or mating disruption), and related expressions are defined analogously.

The term“agronomic” refers to the production of field crops such as for food, feed and fiber and includes the growth of com, soybeans and other legumes, rice, cereal (e.g., wheat, oats, barley, rye, rice, maize), leafy vegetables (e.g., lettuce, cabbage, and other cole crops), fruiting vegetables (e.g., tomatoes, pepper, eggplant crucifers and cucurbits), potatoes, sweet potatoes, grapes, cotton, tree fruits (e.g., pome, stone and citrus), small fruit (berries, cherries) and other specialty crops (e.g., canola, sunflower, olives).

The term “nonagronomic” refers to other than field crops, such as horticultural crops (e.g., greenhouse, nursery or ornamental plants not grown in a field), residential, agricultural, commercial and industrial structures, turf (e.g., sod farm, pasture, golf course, lawn, sports field, etc.), wood products, stored product, agro-forestry and vegetation management, public health (i.e. human) and animal health (e.g., domesticated animals such as pets, livestock and poultry, undomesticated animals such as wildlife) applications.

Nonagronomic applications include protecting an animal from an invertebrate parasitic pest by administering a parasiticidally effective (i.e. biologically effective) amount of a compound of the present invention, typically in the form of a composition formulated for veterinary use, to the animal to be protected. As referred to in the present disclosure and claims, the terms“parasiticidal" and “parasiticidally” refers to observable effects on an invertebrate parasite pest to provide protection of an animal from the pest. Parasiticidal effects typically relate to diminishing the occurrence or activity of the target invertebrate parasitic pest. Such effects on the pest include necrosis, death, retarded growth, diminished mobility or lessened ability to remain on or in the host animal, reduced feeding and inhibition of reproduction. These effects on invertebrate parasite pests provide control (including prevention, reduction or elimination) of parasitic infestation or infection of the animal.

Compounds of the present disclosure may be present either in pure form or as mixtures of different possible isomeric forms such as stereoisomers or constitutional isomers. The various stereoisomers include enantiomers, diastereomers, chiral isomers, atropisomers, conformers, rotamers, tautomers, optical isomers, polymorphs, and geometric isomers. Any desired mixtures of these isomers fall within the scope of the claims of the present disclosure. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other isomer(s) or when separated from the other isomer(s). Additionally, the person skilled in the art knows processes or methods or technology to separate, enrich, and/or to selectively prepare said isomers.
