A compound of formula (I) may move acropetally, basipetally or locally in plant tissue to be active against one or more fungi. Moreover, a compound of formula (I) may be volatile enough to be active in the vapour phase against one or more fungi on the plant. The invention therefore provides a method of combating and controlling insects, acarines, nematodes or molluscs which comprises applying an insecticidally, acaricidally, nematicidally or molluscicidally effective amount of a compound of formula (I), or a composition containing a compound of formula (I), to a pest, a locus of pest, or to a plant susceptible to attack by a pest, and a method of combating and controlling fungi which comprises applying a fungicidally effective amount of a compound of formula (I), or a composition containing a compound of formula (I), to a plant, to a seed of a plant, to the locus of the plant or seed, to soil or to any other growth medium (for example a nutrient solution). The compounds of formula (I) are preferably used against insects, acarines, nematodes or fungi.
The term "plant" as used herein includes seedlings, bushes and trees. Furthermore, the fungicidal method of the invention includes protectant, curative, systemic, eradicant and antisporulant treatments.
As fungicides, the compounds of formula (I) are preferably used for agricultural, horticultural and turfgrass purposes in the form of a composition.
In order to apply a compound of formula (I) as an insecticide, acaricide, nematicide or molluscicide to a pest, a locus of pest, or to a plant susceptible to attack by a pest, or, as a fungicide to a plant, to a seed of a plant, to the locus of the plant or seed, to soil or to any other growth medium, a compound of formula (I) is usually formulated into a composition which includes, in addition to the compound of formula (I), a suitable inert diluent or carrier and, optionally, a surface active agent (SFA). SFAs are chemicals which are able to modify the properties of an interface (for example, liquid/solid, liquid/air or liquid/liquid interfaces) by lowering the interfacial tension and thereby leading to changes in other properties (for example dispersion, emulsification and wetting). It is preferred that all compositions (both solid and liquid formulations) comprise, by weight, 0.0001 to 95%, more preferably 1 to 85%, for example 5 to 60%, of a compound of formula (I). The composition is generally used for the control of pests or fungi such that a compound of formula (I) is applied at a rate of from O.lg to 10kg per hectare, preferably from lg to 6kg per hectare, more preferably from lg to 1kg per hectare. When used in a seed dressing, a compound of formula (I) is used at a rate of 0.000 lg to lOg (for example O.OOlg or 0.05g), preferably 0.005g to lOg, more preferably 0.005g to 4g, per kilogram of seed. In another aspect the present invention provides an insecticidal, acaricidal, nematicidal, molluscicidal or fungicidal composition comprising an insecticidally, acaricidally, nematicidally, molluscicidally or fungicidally effective amount of a compound of formula (I) and a suitable carrier or diluent therefor. The composition is preferably an insecticidal, acaricidal, nematicidal or fungicidal composition.
In a still further aspect the invention provides a method of combating and controlling pests or fungi at a locus which comprises treating the pests or fungi or the locus of the pests or fungi with an insecticidally, acaricidally, nematicidally, molluscicidally or fungicidally effective amount of a composition comprising a compound of formula (I). The compounds of formula (I) are preferably used against insects, acarines, nematodes or fungi.
The compositions can be chosen from a number of formulation types, including dustable powders (DP), soluble powders (SP), water soluble granules (SG), water dispersible granules (WG), wettable powders (WP), granules (GR) (slow or fast release), soluble concentrates (SL), oil miscible liquids (OL), ultra low volume liquids (UL), emulsifiable concentrates (EC), dispersible concentrates (DC), emulsions (both oil in water (EW) and water in oil (EO)), micro-emulsions (ME), suspension concentrates (SC), aerosols, fogging/smoke formulations, capsule suspensions (CS) and seed treatment formulations. The formulation type chosen in any instance will depend upon the particular purpose envisaged and the physical, chemical and biological properties of the compound of formula (I). Dustable powders (DP) may be prepared by mixing a compound of formula (I) with one or more solid diluents (for example natural clays, kaolin, pyrophyllite, bentonite, alumina, montmorillonite, kieselguhr, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulphur, lime, flours, talc and other organic and inorganic solid carriers) and mechanically grinding the mixture to a fine powder. Soluble powders (SP) may be prepared by mixing a compound of formula (I) with one or more water-soluble inorganic salts (such as sodium bicarbonate, sodium carbonate or magnesium sulphate) or one or more water-soluble organic solids (such as a polysaccharide) and, optionally, one or more wetting agents, one or more dispersing agents or a mixture of said agents to improve water dispersibility/solubility. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water soluble granules (SG). Wettable powders (WP) may be prepared by mixing a compound of formula (I) with one or more solid diluents or carriers, one or more wetting agents and, preferably, one or more dispersing agents and, optionally, one or more suspending agents to facilitate the dispersion in liquids. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water dispersible granules (WG).
Granules (GR) may be formed either by granulating a mixture of a compound of formula (I) and one or more powdered solid diluents or carriers, or from pre-formed blank granules by absorbing a compound of formula (I) (or a solution thereof, in a suitable agent) in a porous granular material (such as pumice, attapulgite clays, fuller's earth, kieselguhr, diatomaceous earths or ground corn cobs) or by adsorbing a compound of formula (I) (or a solution thereof, in a suitable agent) on to a hard core material (such as sands, silicates, mineral carbonates, sulphates or phosphates) and drying if necessary. Agents which are commonly used to aid absorption or adsorption include solvents (such as aliphatic and aromatic petroleum solvents, alcohols, ethers, ketones and esters) and sticking agents (such as polyvinyl acetates, polyvinyl alcohols, dextrins, sugars and vegetable oils). One or more other additives may also be included in granules (for example an emulsifying agent, wetting agent or dispersing agent). Dispersible Concentrates (DC) may be prepared by dissolving a compound of formula (I) in water or an organic solvent, such as a ketone, alcohol or glycol ether. These solutions may contain a surface active agent (for example to improve water dilution or prevent crystallisation in a spray tank).
Emulsifiable concentrates (EC) or oil-in-water emulsions (EW) may be prepared by dissolving a compound of formula (I) in an organic solvent (optionally containing one or more wetting agents, one or more emulsifying agents or a mixture of said agents). Suitable organic solvents for use in ECs include aromatic hydrocarbons (such as alkylbenzenes or alkylnaphthalenes, exemplified by SOLVESSO 100, SOLVESSO 150 and SOLVESSO 200; SOLVESSO is a Registered Trade Mark), ketones (such as cyclohexanone or methylcyclohexanone) and alcohols (such as benzyl alcohol, furfuryl alcohol or butanol), N-alkylpyrrolidones (such as N-methylpyrrolidone or N-octylpyrrolidone), dimethyl amides of fatty acids (such as C8-do fatty acid dimethylamide) and chlorinated hydrocarbons. An EC product may spontaneously emulsify on addition to water, to produce an emulsion with sufficient stability to allow spray application through appropriate equipment. Preparation of an EW involves obtaining a compound of formula (I) either as a liquid (if it is not a liquid at room temperature, it may be melted at a reasonable temperature, typically below 70°C) or in solution (by dissolving it in an appropriate solvent) and then emulsifiying the resultant liquid or solution into water containing one or more SFAs, under high shear, to produce an emulsion. Suitable solvents for use in EWs include vegetable oils, chlorinated hydrocarbons (such as chlorobenzenes), aromatic solvents (such as alkylbenzenes or alkylnaphthalenes) and other appropriate organic solvents which have a low solubility in water.
Microemulsions (ME) may be prepared by mixing water with a blend of one or more solvents with one or more SFAs, to produce spontaneously a thermodynamically stable isotropic liquid formulation. A compound of formula (I) is present initially in either the water or the solvent/SFA blend. Suitable solvents for use in MEs include those hereinbefore described for use in in ECs or in EWs. An ME may be either an oil-in- water or a water-in-oil system (which system is present may be determined by conductivity measurements) and may be suitable for mixing water-soluble and oil-soluble pesticides in the same formulation. An ME is suitable for dilution into water, either remaining as a microemulsion or forming a conventional oil-in-water emulsion.
Suspension concentrates (SC) may comprise aqueous or non-aqueous suspensions of finely divided insoluble solid particles of a compound of formula (I). SCs may be prepared by ball or bead milling the solid compound of formula (I) in a suitable medium, optionally with one or more dispersing agents, to produce a fine particle suspension of the compound. One or more wetting agents may be included in the composition and a suspending agent may be included to reduce the rate at which the particles settle. Alternatively, a compound of formula (I) may be dry milled and added to water, containing agents hereinbefore described, to produce the desired end product.
Aerosol formulations comprise a compound of formula (I) and a suitable propellant (for example n-butane). A compound of formula (I) may also be dissolved or dispersed in a suitable medium (for example water or a water miscible liquid, such as n-propanol) to provide compositions for use in non-pressurised, hand-actuated spray pumps. A compound of formula (I) may be mixed in the dry state with a pyrotechnic mixture to form a composition suitable for generating, in an enclosed space, a smoke containing the compound.
Capsule suspensions (CS) may be prepared in a manner similar to the preparation of EW formulations but with an additional polymerisation stage such that an aqueous dispersion of oil droplets is obtained, in which each oil droplet is encapsulated by a polymeric shell and contains a compound of formula (I) and, optionally, a carrier or diluent therefor. The polymeric shell may be produced by either an interfacial polycondensation reaction or by a coacervation procedure. The compositions may provide for controlled release of the compound of formula (I) and they may be used for seed treatment. A compound of formula (I) may also be formulated in a biodegradable polymeric matrix to provide a slow, controlled release of the compound.
A composition may include one or more additives to improve the biological performance of the composition (for example by improving wetting, retention or distribution on surfaces; resistance to rain on treated surfaces; or uptake or mobility of a compound of formula (I)). Such additives include surface active agents, spray additives based on oils, for example certain mineral oils or natural plant oils (such as soy bean and rape seed oil), and blends of these with other bio-enhancing adjuvants (ingredients which may aid or modify the action of a compound of formula (I)).
A compound of formula (I) may also be formulated for use as a seed treatment, for example as a powder composition, including a powder for dry seed treatment (DS), a water soluble powder (SS) or a water dispersible powder for slurry treatment (WS), or as a liquid composition, including a flowable concentrate (FS), a solution (LS) or a capsule suspension (CS). The preparations of DS, SS, WS, FS and LS compositions are very similar to those of, respectively, DP, SP, WP, SC and DC compositions described above. Compositions for treating seed may include an agent for assisting the adhesion of the composition to the seed (for example a mineral oil or a film-forming barrier).
Wetting agents, dispersing agents and emulsifying agents may be surface SFAs of the cationic, anionic, amphoteric or non-ionic type.
Suitable SFAs of the cationic type include quaternary ammonium compounds (for example cetyltrimethyl ammonium bromide), imidazolines and amine salts.
Suitable anionic SFAs include alkali metals salts of fatty acids, salts of aliphatic monoesters of sulphuric acid (for example sodium lauryl sulphate), salts of sulphonated aromatic compounds (for example sodium dodecylbenzenesulphonate, calcium dodecylbenzenesulphonate, butylnaphthalene sulphonate and mixtures of sodium di- wopropyl- and tri-wopropyl-naphthalene sulphonates), ether sulphates, alcohol ether sulphates (for example sodium laureth-3-sulphate), ether carboxylates (for example sodium laureth-3-carboxylate), phosphate esters (products from the reaction between one or more fatty alcohols and phosphoric acid (predominately mono-esters) or phosphorus pentoxide (predominately di-esters), for example the reaction between lauryl alcohol and tetraphosphoric acid; additionally these products may be ethoxylated), sulphosuccinamates, paraffin or olefine sulphonates, taurates and lignosulphonates. Suitable SFAs of the amphoteric type include betaines, propionates and glycinates. Suitable SFAs of the non-ionic type include condensation products of alkylene oxides, such as ethylene oxide, propylene oxide, butylene oxide or mixtures thereof, with fatty alcohols (such as oleyl alcohol or cetyl alcohol) or with alkylphenols (such as octylphenol, nonylphenol or octylcresol); partial esters derived from long chain fatty acids or hexitol anhydrides; condensation products of said partial esters with ethylene oxide; block polymers (comprising ethylene oxide and propylene oxide); alkanolamides; simple esters (for example fatty acid polyethylene glycol esters); amine oxides (for example lauryl dimethyl amine oxide); and lecithins. Suitable suspending agents include hydrophilic colloids (such as polysaccharides, polyvinylpyrrolidone or sodium carboxymethylcellulose) and swelling clays (such as bentonite or attapulgite).
A compound of formula (I) may be applied by any of the known means of applying pesticidal or fungicidal compounds. For example, it may be applied, formulated or unformulated, to the pests or to a locus of the pests (such as a habitat of the pests, or a growing plant liable to infestation by the pests) or to any part of the plant, including the foliage, stems, branches or roots, to the seed before it is planted or to other media in which plants are growing or are to be planted (such as soil surrounding the roots, the soil generally, paddy water or hydroponic culture systems), directly or it may be sprayed on, dusted on, applied by dipping, applied as a cream or paste formulation, applied as a vapour or applied through distribution or incorporation of a composition (such as a granular composition or a composition packed in a water-soluble bag) in soil or an aqueous environment.
A compound of formula (I) may also be injected into plants or sprayed onto vegetation using electrodynamic spraying techniques or other low volume methods, or applied by land or aerial irrigation systems.
Compositions for use as aqueous preparations (aqueous solutions or dispersions) are generally supplied in the form of a concentrate containing a high proportion of the active ingredient, the concentrate being added to water before use. These concentrates, which may include DCs, SCs, ECs, EWs, MEs SGs, SPs, WPs, WGs and CSs, are often required to withstand storage for prolonged periods and, after such storage, to be capable of addition to water to form aqueous preparations which remain homogeneous for a sufficient time to enable them to be applied by conventional spray equipment. Such aqueous preparations may contain varying amounts of a compound of formula (I) (for example 0.0001 to 10%, by weight) depending upon the purpose for which they are to be used.
A compound of formula (I) may be used in mixtures with fertilisers (for example nitrogen-, potassium- or phosphorus-containing fertilisers). Suitable formulation types include granules of fertiliser. The mixtures suitably contain up to 25% by weight of the compound of formula (I).
The invention therefore also provides a fertiliser composition comprising a fertiliser and a compound of formula (I).
The compositions of this invention may contain other compounds having biological activity, for example micronutrients or compounds having similar or complementary fungicidal activity or which possess plant growth regulating, herbicidal, insecticidal, nematicidal or acaricidal activity.
By including another fungicide, the resulting composition may have a broader spectrum of activity or a greater level of intrinsic activity than the compound of formula (I) alone. Further the other fungicide may have a synergistic effect on the fungicidal activity of the compound of formula (I).
The compound of formula (I) may be the sole active ingredient of the composition or it may be admixed with one or more additional active ingredients such as a pesticide, fungicide, synergist, herbicide or plant growth regulator where appropriate. An additional active ingredient may: provide a composition having a broader spectrum of activity or increased persistence at a locus; synergise the activity or complement the activity (for example by increasing the speed of effect or overcoming repellency) of the compound of formula (I); or help to overcome or prevent the development of resistance to individual components. The particular additional active ingredient will depend upon the intended utility of the composition.

In addition to the major chemical classes of pesticide listed above, other pesticides having particular targets may be employed in the composition, if appropriate for the intended utility of the composition. For instance, selective insecticides for particular crops, for example stemborer specific insecticides (such as cartap) or hopper specific insecticides (such as buprofezin) for use in rice may be employed. Alternatively insecticides or acaricides specific for particular insect species/stages may also be included in the compositions (for example acaricidal ovo-larvicides, such as clofentezine, flubenzimine, hexythiazox or tetradifon; acaricidal motilicides, such as dicofol or propargite; acaricides, such as bromopropylate or chlorobenzilate; or growth regulators, such as hydramethylnon, cyromazine, methoprene, chlorfluazuron or diflubenzuron).

Suitable herbicides and plant-growth regulators for inclusion in the compositions will depend upon the intended target and the effect required. An example of a rice selective herbicide which may be included is propanil. An example of a plant growth regulator for use in cotton is PDC™.
Some mixtures may comprise active ingredients which have significantly different physical, chemical or biological properties such that they do not easily lend themselves to the same conventional formulation type. In these circumstances other formulation types may be prepared. For example, where one active ingredient is a water insoluble solid and the other a water insoluble liquid, it may nevertheless be possible to disperse each active ingredient in the same continuous aqueous phase by dispersing the solid active ingredient as a suspension (using a preparation analogous to that of an SC) but dispersing the liquid active ingredient as an emulsion (using a preparation analogous to that of an EW). The resultant composition is a suspoemulsion (SE) formulation.
The invention is illustrated by the following Examples:
EXAMPLE 1 This Example illustrates the preparation of N-(4-chloro-3-methylisothiazol-5-yl)thio(2- [2,2-dimethylpropyl] benzoxazol-5-yl)acetamide.
Step 1 - Preparation of 5-amino-4-chloro-3-methylisothiazole.
5-Amino-3-methylisothiazole hydrochloride (250g, 1.66 mole) was suspended in dichloromethane( 1.251) and stirred at 8°C. Sulfuryl chloride(146.8ml, 1.83 mole) was added dropwise over lhour and during this addition the temperature of the reaction mixture was maintained between 10 and 15°C. As the sulfuryl chloride was added the suspended particles dissolved and a dark oil began to fall out of solution. The resultant two-phase mixture was stirred at 10°C for 15minute. The mixture was cooled to below 10°C and quenched by careful addition of aqueous potassium carbonate solution (367.3g, 2.66 mole, of potassium carbonate in 1 litre of water). The two phases were separated and the aqueous layer extracted with dichloromethane (600ml+400ml). The combined organic layers were dried over anhydrous magnesium sulfate, filtered and the filtrate was concentrated in vacuo. The residue was slurried in hexane (~500ml) for lhour, filtered and dried to give 5-amino-4- chloro-3-methyl-isothiazole as a red-brown-solid (228.7g, 93%), m.p. 69-71°C. 1H NMR (CDC13) δ: 2.3(3H,s); 4.6(2H, br.s)ppm. Step 2 - Preparation of methyl (4-hydroxyphenyl)acetate. Hydrogen chloride was bubbled through a solution of (4-hydroxyphenyl) acetic acid (25g , 0.16mole) in methanol (100ml) at room temperature. An exotherm resulted in the solution refluxing for about lOminutes. The mixture was allowed to cool to room temperature and the solvent was evaporated in vacuo to afford methyl (4- hydroxyphenyl)acetate as a yellow oil (27.5g) which crystallised on seeding, m.p. 46-52°C.
1H NMR (CDC13) δ: 3.57(2H,s); 3.71(3H,s); 6.0(lH,br); 6.76(2H,m); 7.10(2H,m)pρm. Step 3 - Preparation of methyl (4-hydroxy-3-nitrophenyl)acetate.
Nitric acid (69% by weight, 16M, 20ml) was added dropwise to a solution of methyl (4-hydroxyphenyl)acetate [from step 2] (50.0g, 0.3mole) in acetic acid (500ml), maintaining the temperature of the reaction below 15°C by external cooling. (An induction period was observed for this reaction.) Once gas chromatographic analysis had confirmed that the reaction was complete, the mixture was carefully quenched into water (21) with vigorous stirring. An emulsion formed which subsequently crystallised. After filtration, washing with water and drying, the desired product was obtained as a yellow powder.

Methyl (4-hydroxy-3-nitrophenyl)acetate [from step 3] (48.9g, 0.23mole) and 5% palladium on carbon were suspended in methanol and the resulting mixture was hydrogenated until all the starting material had been consumed. The reaction mixture was filtered to remove the catalyst and the filter-cake was washed with methanol. The combined filtrate and washings were concentrated in vacuo, affording methyl (3-amino-4- hydroxyphenyl)acetate as a solid (41.0g). 1H NMR (d6-DMSO) δ: 3.51(2H,s); 4.45(2H,b); 6.20(lH,dd); 6.40(lH,d); 6.49(lH,d);

Once the addition was complete, the mixture was allowed to stir at room temperature for lhour. The reaction mixture was poured slowly into water (50ml) and concentrated hydrochloride acid was added until the pH of the mixture was below pH6. The mixture was stirred for lhour then filtered and the solid was washed thoroughly with water and dried.

The residue was taken up in xylene (10ml), 5-amino-4-chloro-3-methylisothiazole [from step 1] (0.829g, O.OOόmole) was added and then the mixture was heated under reflux for 2hour. The mixture was cooled to room temperature, diluted with ethyl acetate and washed with brine. The organic solution was dried over anhydrous magnesium sulfate, filtered and the filtrate was evaporated in vacuo. The residue was further purified by flash column chromatography on silica gel, eluting with a 2:1 mixture of hexane: ethyl acetate, to give N-(4-chloro-3-methylisothiazol-5-yl)-[2-(2,2- dimethylpropyl)-benzoxazol-5-yl] acetamide (0.325g) as a pale orange solid, m.p. 144-145°C. 1H NMR (CDCI3) δ: l.l(9H,s); 2.35(3H,s); 2.85(2H,s); 3.95(2H,s); 7.25(lH,dd);

The solution was treated portion-wise over 2hour with 2,4-bis(p-tolylthio)-l,3,2,4-dithiadiphosphetane-2,4-disulfide (18g), heated to reflux for a further 5hour and was then allowed to cool to ambient temperature. The mixture was filtered, the insoluble material was washed with fluorobenzene and the combined filtrate was diluted with hexane (100m) and was then applied to a short column of silica. The column was eluted with hexane then mixtures of hexane and ethyl acetate (ratio 10:1 to 6:1).

EXAMPLE 10 This Example illustrates the pesticidal/insecticidal properties of compounds of formula (I). The activities of individual compounds of formula (I) were determined using a variety of pests. The pests were treated with a liquid composition containing 500 parts per million (ppm) by weight of a compound of formula (I). Each composition was made by dissolving the compound in an acetone and ethanol (50:50 by volume) mixture and diluting the solution with water containing 0.05% by volume of a wetting agent, SYNPERONIC NP8, until the liquid composition contained the required concentration of the compound. SYNPERONIC is a registered trade mark.
The test procedure adopted with regard to each pest was essentially the same and comprised supporting a number of the pests on a medium, which was usually a substrate, a host plant or a foodstuff on which the pests feed, and treating either or both the medium and the pests with a composition. Pest mortality was assessed usually between two and five days after treatment.
In each test against peach potato aphids (Myzus persicae), Chinese cabbage leaves were infested with aphids, the infested leaves were sprayed with a test composition and pest mortality was assessed after three days.
Similar tests were conducted against, independently, two-spotted spider mites (Tetranychus urticae), fruit flies (Drosophila melanogaster), tobacco budworms (Heliothis virescens), diamond back moth (Plutella xylostella) and corn root worm (Diabrotica balteata). Tests were also conducted against root knot nematodes (Meloidogyne incognita) using an in vitro test in which nematodes were suspended in a liquid composition which had been prepared as described above except that it contained a concentration of 12.5ppm by weight of a compound of formula (I) and it contained no SYNPERONIC NP8.
Results from these tests are displayed in Table 80, in which each mortality (score) is designated as 9, 5 or 0 wherein 9 indicates 80-100% mortality, 5 indicates 40-79% mortality and 0 indicates less than 40% mortality; and Dm represents Drosophila melanogaster; Mp represents Myzus persicae; Hv represents Heliothis virescens; Px represents Plutella xylostella; Tu represents Tetranychus urticae; Db represents Diabrotica balteata; and Mi represents Meloidogyne incognita.

EXAMPLE 11
This Example illustrates the fungicidal properties of compounds of formula (I). The compounds were tested against a variety of foliar fungal diseases of plants. The technique employed was as follows.
Plants were grown in John Innes Potting Compost (No.l or 2) in 4cm diameter, 3.5cm depth minipots. The test compounds were individually formulated as a solution either in acetone or acetone/ethanol (1: 1 by volume) which was diluted in deionised water to a concentration of lOOppm (that is, lmg of compound in a final volume of 10ml) immediately before use. When foliar sprays were applied to monocotyledonous crops, TWEEN 20 (0.1% by volume) was added. TWEEN is a registered trade mark. Individual compounds of formula (I) were applied as a foliar (Folr) application (where the chemical solution was applied to the foliage of the test plants by spraying the plant to maximum droplet retention.)
These tests were carried out against Uncinula necator (UNCTNE), on vines; Phytophthora infestans lycopersici (PHYTIN) on tomatoes; Puccinia recondita (PUCCRT), on wheat; and Pyricularia oryzae (PYRIOR) on rice. Each treatment was applied to two or more replicate plants for Phytophthora infestans lycopersici and Uncinula necator. For tests on Puccinia recondita and Pyricularia oryzae two replicate pots each containing 6 to 10 plants were used for each treatment. The plants were inoculated one day before (Erad) or one day after (Prot) chemical application. The Phytophthora infestans lycopersici, Puccinia recondita and Pyricularia oryzae plants were inoculated with a calibrated fungal spore suspension. The Uncinula necator plants were inoculated using a 'blowing' inoculation technique.
After chemical application and inoculation, the plants were incubated under high humidity conditions and then put into an appropriate environment to allow infection to proceed, until the disease was ready for assessment. The time period between chemical application and assessment varied from five to fourteen days according to the disease and environment. However, each individual disease was assessed after the same time period for all compounds. Assessments were performed on each of two leaves on each of the replicate plants for
Phytophthora infestans lycopersici. Assessments were performed on a single leaf of each of the replicate plants for Uncinula necator. For Puccinia recondita and Pyricularia recondita assessments were carried out collectively on the plants in each replicate pot.
The disease level present (that is, the percentage leaf area covered by actively sporulating disease) was assessed visually. For each treatment, the assessed values for all its replicates were meaned to provide mean disease values. Untreated control plants were assessed in the same manner. The data were then processed by the method, described hereinafter, to provide PRCO (Percentage Reduction from Control) values.
An example of a typical calculation is as follows:
Mean disease level for treatment A = 25% Mean disease level on untreated controls = 85% PRCO = 100 - { Mean disease level for treatment A } x 100 {Mean disease level on untreated controls}
= 100 - (25 x 100) = 70.6
85
The PRCO is then rounded to the nearest whole number; therefore, in this particular example, the PRCO result is 71. It is possible for negative PRCO values to be obtained.
