The efficacy of new fungicide mixtures in controlling Plasmopara viticola in grapevine was evaluated in field trials. The efficacies of Profiler (fluopicolide + fosetyl-Al) and the standard fungicide Mikal Flash (fosetyl-Al + folpet) were tested at Radmilovac and Slankamenački Vinogradi in 2006 and 2007. Both tested fungicides exhibited high efficacy in controlling grape downy mildew. There were no significant differencies in the efficacies of Profiler (96.1-99.7%) and Mikal Flash (94.9-99.2%). Our experiments showed that the investigated fungicide mixture fluopicolide + fosetyl-Al is highly effective against P. viticola, even when it it is applied at long intervals and under high disease pressure.
