Attività di fungicidi comunemente utilizzati in vigneto su specie di Aspergillus gruppo Nigri

The activity of sixteen fungicides commonly used in vineyard against three species belonging to the group Nigri of the genus Aspergillus, A. carbonarius, A. awamori and A. niger, was tested on Czapek yeast extract Agar and on experimentally inoculated detached berrie. No activity was shown by fungicides containing dinocap, quinoxyfen, fosetyl Aluminium, Cu hydroxide and fenhexamid, while reduced efficiency was observed for the fungicides contanining myclobutanil, penconazole, trifloxystrobin, azoxystrobin, procymidone and iprodione. The fungicide containing mancozeb was efficient only against A. niger, but the best results in inhibiting the fungal growth were obtained by using formulations containing folpet and particularly pyrimethanil anf cyprodinil+fludioxonil.
