Among the preferred compounds of the invention, the compounds can be mentioned in which Ar represents an optionally substituted pyridinyl radical, for example the compounds in which Ar represents a 6-chloro 3pyridinyl radical; there can also be mentioned the compounds of formula (I) in which X represents a nitrogen atom.
In particular, a subject of the invention is also the compounds of formula (I) in which R represents a linear, branched or cyclic alkyl radical containing up to 8 carbon atoms optionally substituted by one or more halogen atoms, such as for example a terbutyl radical. or also a trichloromethyl radical. Quite especially a subject of the invention is the compounds of Examples 3 and 5A. 30 The compounds of formula (I) have useful properties which allow their use for combating parasites. It can be for example for combating parasites of vegetation, whether it be parasites of the soil or of the parts above ground, parasites of premises and parasites of warm- blooded animals. 35 Thus it is that the products of the'invention can be used to combat parasitic insects, nematodes and acaridae of vegetation and animals. In particular a subject of the invention is the use of 3 the compounds of formula (I) to combat parasites of vegetation, parasites of premises and parasites of warmblooded animals.
The products of formula (I) can also be used to combat insects in premises, in particular to combat flies. mosquitoes and cockroaches.
The products of formula (I) can also be used to combat insects and other parasites of the soil, for example Coleoptera, such as Diabrotica, click beetles and May beetle grubs, Myriapoda such as scutigeridae and blanjules, and Diptera such as cecydomia and Lepidoptera such as owlet moths.
They are preferably used at doses of between 5 g and 300 g of active ingredient per hectare.
All these properties make the products of formula (I) products which correspond perfectly-to the requirements of the modern agrochemical industry: they allow the protection of crops while preserving the environment.
The products of formula (I) can also be used to combat parasitic acaridae and nematodes of vegetation..
