FIELD OF THE INVENTION

The present invention relates to novel nitrone compounds. More particularly, the present invention relates to a nitrone compound of formula (I) and to a process for preparation thereof. The present invention further relates to a use of nitrone compound of formula (I) as a crop protection agent for the control of phytopathogenic microorganisms such as plant parasitic nematodes and plant pathogens.

BACKGROUND OF THE INVENTION

Heterocyclic compounds carrying a fluroalkenyl chain have been described in literature for use as pesticides and, in particular, as nematicides. For example, W02017002100, DE10254876, W02004005268, W02003049541, W02003029231, W02002006259, W02002006257,

W02002006256, W02001066529, W0200102378, WO95/24403 and W086/07590.

JP500037/1988 discloses polyhaloalkene compounds which have nematicidal activity. JP176141/1997 discloses thiazole compounds having insecticidal and acaricidal activity.

Nitrones are the N-oxide of imines, they are first used as agents to trap free-radicals (known as spin trapping) in chemical systems and subsequently, in biochemical systems.

US3834073 discloses phenyl nitrone derivatives for controlling plant pathogens in soil by soil treatment or by treatment of the crop plant seeds.

The control of damages to crops caused by phytopathogenic microorganisms and pests is extremely important in achieving high crop efficiency. For instance, plant disease damage to ornamental, vegetable, field, cereal and fruit crops can cause significant reduction in productivity and thereby result in increased cost to the consumer. Many products are commercially available to control such damages. The need continues for new compounds which are more effective, less costly, less toxic, environmentally safer and/or have different modes of action.

The effectiveness of the diflurobutenes, trifluorobutenes and other compounds described in the prior art is not fully satisfactory in various cases. Therefore, it is always of high interest in agriculture to find novel pesticidal compounds in order to avoid and/or control the development of microorganisms such as fungal or bacterial pathogens or pests being resistant to known active ingredients. It is therefore of high interest to use novel compounds being more active than those already known, with the aim of decreasing the amounts of active compound to be used, whilst at the same time maintaining an effectiveness at least equivalent to the already known compounds.

The present invention describes compounds of formula (I) which possess the above mentioned effects or advantages. Such compounds of formula (I), namely nitrone compounds wherein the heterocyclic ring is substituted according to the invention, show unexpected and significantly higher activity against undesired microorganisms such as fungal or bacterial pathogens or against pests such as nematodes or insects.

SUMMARY OF THE INVENTION

The present invention provides a novel nitrone compound of formula (I),

Formula (I)

wherein, R ¹ , R ² , R ³ , R ⁴ , A, A ¹ and n are as defined in the detailed description.

In one embodiment, the present invention provides a process for the preparation of compounds of formula (I).

In another embodiment, the present invention provides a use of compound of formula (I) as crop protection agent for the control of phytopathogenic microorganisms such as plant parasitic nematodes and plant pathogens.

DESCRIPTION

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“pesticide” in each case also always comprises the term “crop protection agent”.

The term“invertebrate pest” includes arthropods, gastropods and nematodes 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 (Trematoda), acanthocephala and tapeworms (Cestoda).

The term “undesired microorganisms” or“phytopathogenic microorganisms” such as f ingal or bacterial pathogens includes Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes and Pseudomonadaceae, Rhizobiaceae, Enterobacteriaceae, Corynebacteriaceae and Streptomycetaceae respectively.

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 and fiber and includes the growth of corn, 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.

The 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.

Accordingly, the present invention also makes available a composition comprising a compound of the invention and an agronomical carrier and optionally one or more customary formulation auxiliaries. The compositions are prepared in a manner known per se, in the absence of auxiliaries for example by grinding, screening and/or compressing a solid compound of the present invention and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the compound of the present invention with the auxiliary (auxiliaries). In the case of solid compounds of the invention, the grinding/milling of the compounds is to ensure specific particle size. These processes for the preparation of the compositions and the use of the compounds of the invention for the preparation of these compositions are also a subject of the invention.

Examples of compositions for use in agriculture are emulsifiable concentrates, suspension concentrates, microemulsions, oil dispersibles, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, soluble powders, dispersible powders, wettable powders, dusts, granules or encapsulations in polymeric substances, which comprise - at least - a compound according to the invention and the type of composition is to be selected to suit the intended aims and the prevailing circumstances.

Examples of suitable liquid carriers are unhydrogenated or partially hydrogenated aromatic hydrocarbons, preferably the fractions Cs to C12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffins or cyclohexane, alcohols such as ethanol, propanol or butanol, glycols and their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol or ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents, such as N-methylpyrrolid-2-one, dimethyl sulfoxide or N,N- dimethylformamide, water, unepoxidized or epoxidized vegetable oils, such as unexpodized or epoxidized rapeseed, castor, coconut or soya oil, and silicone oils. Examples of solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly disperse silicas or highly disperse absorbtive polymers. Suitable particulate adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are calcite or sand. In addition, a large number of granulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues. Suitable surface-active compounds are, depending on the type of the active ingredient to be formulated, non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties. The surfactants mentioned below are only to be considered as examples; a large number of further surfactants which are conventionally used in the art of formulation and suitable according to the invention are described in the relevant literature. Suitable non-ionic surfactants are, especially, polyglycol ether derivatives of aliphatic or (cyclo) aliphatic alcohols, of saturated or unsaturated fatty acids or of alkyl phenols which may contain approximately 3 to approximately 30 glycol ether groups and approximately 8 to approximately 20 carbon atoms in the (cyclo)aliphatic hydrocarbon radical or approximately 6 to approximately 18 carbon atoms in the alkyl moiety of the alkyl phenols. Also suitable are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol or alkyl polypropylene glycol having 1 to approximately 10 carbon atoms in the alkyl chain and approximately 20 to approximately 250 ethylene glycol ether groups and approximately 10 to approximately 100 propylene glycol ether groups. Normally, the abovementioned compounds contain 1 to approximately 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenoxypolyethoxyethanol, castor oil poly glycol ether, polypropylene glycol/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol or octylphenoxypolyethoxyethanol. Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate. The cationic surfactants are, especially, quarternary ammonium salts which generally have at least one alkyl radical of approximately 8 to approximately 22 Carbon atoms as substituents and as further substituents (unhalogenated or halogenated) lower alkyl or hydroxyalkyl or benzyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples are stearyltrimethylammonium chloride and benzylbis(2-chloroethyl)ethylammonium bromide.

Examples of suitable anionic surfactants are water-soluble soaps or water-soluble synthetic surface- active compounds. Examples of suitable soaps are the alkali, alkaline earth or (unsubstituted or substituted) ammonium salts of fatty acids having approximately 10 to approximately 22 Carbon atoms, such as the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which are obtainable for example from coconut or tall oil; mention must also be made of the fatty acid methyl taurates. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. As a rule, the fatty sulfonates and fatty sulfates are present as alkali, alkaline earth or (substituted or unsubstituted) ammonium salts and they generally have an alkyl radical of approximately 8 to approximately 22 Carbon atoms, alkyl also to be understood as including the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or calcium salts of lignosulfonic acid, of the dodecylsulphuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulphuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulphonyl groups and a fatty acid radical of approximately 8 to approximately 22 Carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of decylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensate. Also possible are, furthermore, suitable phosphates, such as salts of the phosphoric ester of a p- nonylphenol/(4-l4)ethylene oxide adduct, or phospholipids.

As a rule, the compositions comprise 0.1 to 99%, especially 0.1 to 95%, of compound according to the present invention and 1 to 99.9%, especially 5 to 99.9%, of at least one solid or liquid carrier, it being possible as a rule for 0 to 25%, especially 0.1 to 20%, of the composition to be surfactants (% in each case meaning percent by weight). Whereas concentrated compositions tend to be preferred for commercial goods, the end consumer as a rule uses dilute compositions which have substantially lower concentrations of active ingredient.

Examples of foliar formulation types for pre-mix compositions are:

Whereas, examples of seed treatment formulation types for pre-mix compositions are:

Examples of formulation types suitable for tank-mix compositions are solutions, dilute emulsions, suspensions, or a mixture thereof, and dusts.

As with the nature of the formulations, the methods of application, such as foliar, drench, spraying, atomizing, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

The tank-mix compositions are generally prepared by diluting with a solvent (for example, water) the one or more pre-mix compositions containing different pesticides, and optionally further auxiliaries. Suitable carriers and adjuvants can be solid or liquid and are the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers.

Typically, a pre mix formulation for foliar application comprises 0.1 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.9 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.

Normally, a tank-mix formulation for seed treatment application comprises 0.25 to 80%, especially 1 to 75%, of the desired ingredients, and 99.75 to 20%, especially 99 to 25%, of a solid or liquid auxiliaries (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 40%, especially 0.5 to 30%, based on the tank-mix formulation.

Typically, a pre-mix formulation for seed treatment application comprises 0.5 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation whereas commercial products will preferably be formulated as concentrates (e.g., pre-mix composition (formulation)), the end user will normally employ dilute formulations (e.g., tank mix composition).

Preferred seed treatment pre-mix formulations are aqueous suspension concentrates. The formulation can be applied to the seeds using conventional treating techniques and machines, such as fluidized bed techniques, the roller mill method, roto static seed treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The seeds may be pre sized before coating. After coating, the seeds are typically dried and then transferred to a sizing machine for sizing. Such procedures are known in the art. The compounds of the present invention are particularly suited for use in soil and seed treatment applications.

In general, the pre-mix compositions of the invention contain 0.5 to 99.9% especially 1 to 95%, advantageously 1 to 50%, by mass of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, by mass of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries (or adjuvant) can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, by mass based on the mass of the pre-mix formulation.

Suitable target plants are, in particular, cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar or fodder beet; fruit, for example pomaceous fruit, stone fruit or soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soya; oil plants, such as oilseed rape, mustard, poppies, olives, sunflowers, coconut, castor, cocoa or ground nuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or bell peppers; Lauraceae, such as avocado, Cinnamonium or camphor; and also tobacco, nuts, coffee, eggplants, sugarcane, tea, pepper, grapevines, hops, the plantain family, latex plants and ornamentals (such as flowers, and lawn grass or turf). In an embodiment, the plant is selected from cereals, corn, soybean, rice, sugarcane, vegetables and oil plants.

The term“plant” is to be understood as including also plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesizing one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus and also plants which have been selected or hybridized to preserve and / or attain a desired trait, such as insect, fungi and /or nematode resistance. Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins from Bacillus cereus or Bacillus popilliae·, or insecticidal proteins from Bacillus thuringiensis, such as 8-endotoxins, e.g. CrylAb, CrylAc, CrylF, CrylFa2, Cry2Ab, Cry3A, Cry3Bbl or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vipl, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus, toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl- transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases. In the context of the present invention there are to be understood by 8-endotoxins, for example CrylAb, CrylAc, CrylF, CrylFa2, Cry2Ab, Cry3A, Cry3Bbl or Cry9C, or vegetative insecticidal proteins (Vip), for example Vipl, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins. Flybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated CrylAb, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G- recognition sequence is inserted into a Cry3A toxin (see WO 03/018810). Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073. The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. Cryl-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0 367474, EP-A-0 401 979 and WO 90/13651. The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera). Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available.

In one embodiment, the present invention provides a combination comprising the compound of general formula (I), stereoisomer, agriculturally acceptable salts, tautomers or N-oxides thereof and one or more active compatible compound selected from fungicides, insecticides, nematicides, acaricides, biopesticides, herbicides, plant growth regulators, antibiotics, nutrients or fertili ers.

Compounds of this invention are effective for controlling nematodes and/or fungal pathogens of agronomic plants, both growing and harvested, when employed alone, they may also be used in combination with other biological active agents used in agriculture, such as one or more nematicides, insecticides, acaricides, fungicides, bactericides, plant activator, molluscicide, and pheromones (whether chemical or biological). Mixing the compounds of the invention or the compositions thereof in the use form as pesticides with other pesticides frequently results in a broader pesticidal spectrum of action. For example, the formula (I) compounds of this invention may be used effectively in conjunction or combination with pyrethroids, neonicotinoids, macrolides, diamides, phosphates, carbamates, cyclodienes, formamidines, phenol tin compounds, chlorinated hydrocarbons, benzoylphenyl ureas, pyrroles and the like.

The activity of the compositions according to the invention can be broadened considerably, and adapted to prevailing circumstances, by adding, for example, one or more insecticidally, acaricidally, nematicidally and/or fungicidally active agents. The combinations compounds of formula (I) with other insecticidally, acaricidally, nematicidally and/or fungicidally active agents may also have further surprising advantages. For example, better tolerance by plants, reduced phytotoxicity, pests or fungi can be controlled in their different development stages or better behavior during their production, for example during grinding or mixing, during their storage or during their use.

The known and reported active compounds such as fungicides, insecticides, nematicides, acaricides, biopesticides, herbicides, safeners, plant growth regulators, antibiotics, fertilizers and nutrients can be combined with at least one compound of formula I of the present invention.

CHEMISTRY EXAMPLES:

The following examples set forth the manner and process of making compounds of the present invention without being a limitation thereof and include the best mode contemplated by the inventors for carrying out the invention.

Example 1: N-methyl-l-(2-((3,4,4-trifluorobut-3-en-l-yl)sulfonyl)thiazo l-5-yl)methanimine oxide Step 1: Preparation of 2-((3, 4, 4-trifluorobut-3-en-l-yl)thio)thiazole

To a solution of thiazole-2-thiol (1 g, 8.5 mmol) in acetonitrile (10 mL), potassium carbonate (1.8 g, 12.8 mmol) was added at 25 °C and stirred for 30 min. To the resulting reaction mixture, 4-Chloro- 1,1, 2-trifluorobut-l-ene (1.3 g, 9.4 mmol) was added and stirred at 60 °C for 4 h. After completion of the reaction, the reaction mixture was diluted with ethyl acetate (30 mL) followed by water (30 mL) and acidified to pH 4 using 1 N hydrochloric acid.

Meloidogyne incognita: IN VIVO TEST

Cucumber plants were grown in seedling trays containing a mixture of Sand:Soil:FYM:Cocopeat in ratio of 1:1: 1:1. One mL of test compounds at the desired concentrations was applied into the soil mixture with the help of a micropipette when the cucumber seedlings were ten days old and inoculated with approximately 2000 freshly hatched second-stage juveniles of Meloidogyne incognita. The treated plants were allowed to grow at 27 °C under greenhouse conditions. Observation of gall rating was recorded after 15 days of application. Plants were carefully uprooted and roots were washed thoroughly. The gall rating was observed on 0-10 scale as described by Zeck (1971) as mentioned below:

0 = no galls

1 = very few small galls

2 = numerous small galls

3 = numerous small galls of which some are grown together

4 = numerous small and some big galls

5 = 25% of roots severely galled

6 = 50% of roots severely galled

7 = 75% of roots severely galled

8 = no healthy roots but plant is still green

9 = roots rotting and plant dying

10 = plant and roots dead Compounds 1 3 4 5 6 9 10 13 15 16 19 20 21 22 24 25 26 27 28 30 38 40
