where Het is a 5- or 6-membered heterocyclic ring containing one to three heteroatoms, each independently selected from oxygen, nitrogen and sulfur, the ring being replaced with the groups R ^ 3 ^, R ^ 4 ^ and R ^ 5 ^ ; R ^ 1 ^ and R ^ 2 ^ are independently H, halo, C ~ 1-4 ~ haloalkyl; and R ^ 3 ^, R ^ 4 ^ and R ^ 5 ^ are each, independently, H, halo, C ^ 1-4 ~ alkyl, C ~ 1-4 ~ haloalkyl or C ~ 1-4 ~ haloalkoxy, provided that at least one between R ^ 3 ^, R ^ 4 ^ and R ^ 5 ^ is not H; to the preparation of these compounds, to new intermediates used in their preparation, to agrochemical compositions that include at least one of the new compounds as an active ingredient, to the preparation of the compositions and to the use of the active ingredients or compositions in agriculture or horticulture for control or prevention of plant infestations by phytopathogenic microorganisms, especially fungi. |
