Certain triazolo[1 ,5-a]pyrimidine derivatives with cyclic amines in position 7 have been proposed for controlling plant-destructive fungi, for example in WO 98/46607, US 6117876
and US 6297251. However, the action of those preparations is not satisfactory in all aspects of agricultural needs. Surprisingly, with the compounds of formula I, new kinds of fungicides having a high level of biological actitivity have now been found.
The compounds of formula I can be obtained by coupling of a compound of formula II, wherein R7, R8 and R9 are as defined for formula I and Hal is halogen, preferably fluorine, chlorine or bromine, with a compound of formula III, wherein R1, R2, R3, R4, R5, R6, R10, R11, X, m, n, j and w are as defined for formula I.
The reaction (Il + III → I) can be carried out in a manner known per se for the transformation of amines with heterocyclic halides, e.g. 4-halopyrimidines or 7-halotriazolo[1 ,5- a]pyrimidines. Preferably the reaction is carried out in solution. Preferred are either organic solvents like N,N-dimethylformamide, N,N-dimethylacetamide, acetonitrile, dioxane, N- methylpyrrolidon, methanol, ethanol or dimethylsulfoxide, or organic solvents, like toluene or xylene in mixture with water and a phase transfer catalyst. The reaction is advantageously
carried out in the presence of a base. In general all types of organic or inorganic bases may be used, for instance triethylamine, diisopropylethylamine, pyridine, 4-dimethylaminopyridine, sodium hydroxide, potassium hydroxide, sodium methoxide, sodium ethoxide, sodium carbonate or potassium carbonate. Reaction temperatures are between 0 0C and +100 0C, preferably between +10 0C and +50 0C. The reaction of cyclic amines with compounds of formula Il is already described in WO 98/46607, US 6297251 and US 6117876.
The compounds of formula II, wherein R7, R8 and R9 are as defined for formula I and Hal is halogen, preferably fluorine, chlorine or bromine, can be obtained by halogenation of a compound of formula IV, wherein R7 and R9 are as defined for formula I and R15 is hydroxy, CrC6alkyl or cyano.
The preparation of compounds of formula Il is already described in WO 2002/038565, US 6297251 and US 6117876.
The compounds of formula III, wherein R1, R2, R3, R4, R5, R6, R10, R11, X, m, n, j and w are as defined for formula I, can be obtained by known methods for the synthesis of annulated nitrogen-heterocycles.
For instance, the synthesis of 3-aza-bicyclo[3.1.0]hexanes of formula (Ilia) can be achieved from acrylates of formula (V), following a route described in Synthesis and Chemistry of Agrochemicals 1987, 401 - 408 and US 4183857.

Surprisingly, it has now been found that the novel compounds of formula I have, for practical purposes, a very advantageous spectrum of activities for protecting plants against diseases that are caused by fungi as well as by bacteria and viruses.
The compounds of formula I can be used in the agricultural sector and related fields of use as active ingredients for controlling plant pests or on non-living materials for control of spoilage microorganisms or organisms potentially harmfull to man. The novel compounds are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and are used for protecting numerous cultivated plants. The compounds of formula I can be used to inhibit or destroy the pests that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later e.g. from phytopathogenic microorganisms.
It is also possible to use compounds of formula I as dressing agents for the treatment of plant propagation material, e.g., seed, such as fruits, tubers or grains, or plant cuttings (for example rice), for the protection against fungal infections as well as against
phytopathogenic fungi occurring in the soil. The propagation material can be treated with a composition comprising a compound of formula I before planting: seed, for example, can be dressed before being sown. The active ingredients according to the invention can also be applied to grains (coating), either by impregnating the seeds in a liquid formulation or by coating them with a solid formulation. The composition can also be applied to the planting site when the propagation material is being planted, for example, to the seed furrow during sowing. The invention relates also to such methods of treating plant propagation material and to the plant propagation material so treated.
Furthermore the compounds according to present invention can be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage, in hygiene management.
In addition, the invention could be used to protect non-living materials from fungal attack, e.g. lumber, wall boards and paint.
The compounds of formula I are, for example, effective against the phytopathogenic fungi of the following classes: Fungi imperfecti (e.g. Botrytis spp., Alternaήa spp.) and Basidiomycetes (e.g. Rhizoctonia spp., Hemileia spp., Puccinia spp., Phakopsora spp.). Additionally, they are also effective against Ascomycetes (e.g. Ventuήa spp., Blumeria spp., Podosphaera leucotricha, Monilinia spp., Fusarium spp., Uncinula spp., Mycosphaerella spp., Pyrenophora spp., Rhynchosporium secalis, Magnaporthe spp., Colletotrichum spp.) and Oomycetes (e.g. Phytophthora spp., Pythium spp., Plasmopara spp.). Outstanding activity has been observed against powdery mildews (e.g. Uncinula necator), rusts (e.g. Puccinia spp.) and leaf spots (e.g. Septoria tritici). Furthermore, the novel compounds of formula I are effective against phytopathogenic bacteria and viruses (e.g. against Xanthomonas spp, Pseudomonas spp, Erwinia amylovora as well as against the tobacco mosaic virus).
Within the scope of present invention, target crops to be protected typically comprise the following species of plants: cereal (wheat, barley, rye, oat, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, drupes and soft fruit (apples,
pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucumber plants (pumpkins, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamomum, camphor) or plants such as tobacco, nuts, coffee, eggplants, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, as well as turf and ornamentals.
The target crops in accordance with the invention include conventional as well as genetically enhanced or engineered varieties such as, for example, insect resistant (e.g. Bt. and VIP varieties) as well as disease resistant, herbicide tolerant (e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®) and nematode tolerant varieties. By way of example, suitable genetically enhanced or engineered crop varieties include the Stoneville 5599BR cotton and Stoneville 4892BR cotton varieties.
The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation. To this end they are conve- niently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions or suspensions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e.g. in polymeric substances. As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.
Suitable carriers and adjuvants can be solid or liquid and are substances useful in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO 97/33890.
The compounds of formula I are normally used in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be e.g. fertilizers or micronutrient donors or other preparations, which influence the growth of plants. They can also be selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.
The compounds of formula I are normally used in the form of fungicidal compositions for controlling and protecting against phytopathogenic microorganisms, comprising as active ingredient at least one compound of formula I, in free form or in agrochemically usable salt form, and at least one of the above-mentioned adjuvants.

A method of controlling and preventing an infestation of crop plants or of non-living materials by phytopathogenic or spoilage microorganisms or organisms potentially harmful to man, especially fungal organisms, which comprises the application of a compound of formula I as active ingredient to the plants, to parts of the plants or to the locus thereof, or to any part of the non-living materials.
A preferred method of controlling and preventing an infestation of crop plants by phytopathogenic microorganisms, especially fungal organisms, which comprises the
application of a compound of formula I, or an agrochemical composition which contains at least one of said compounds, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen. However, the compounds of formula I can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e.g. in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula I may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.
A formulation [that is, a composition containing the compound of formula I] and, if desired, a solid or liquid adjuvant or monomers for encapsulating the compound of formula I, is prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface active compounds (surfactants).
The agrochemical formulations will usually contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of the compound of formula I, 99.9 to 1 % by weight, preferably 99.8 to 5% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant.
Advantageous rates of application are normally from 5g to 2kg of active ingredient (a.i.) per hectare (ha), preferably from 10g to 1kg a.i./ha, most preferably from 2Og to 60Og a.i./ha. When used as seed drenching agent, convenient dosages are from 10mg to 1g of active substance per kg of seeds.
Whereas it is preferred to formulate commercial products as concentrates, the end user will normally use dilute formulations.
