The efficacy of several fungicide mixtures in controlling Venturia inaequalis in apple was
evaluated in field trials. The efficacies of Flint Plus (trifloxystrobin + captan) and Tercel (pyraclostrobin
+ dithianon) in comparison with standard fungicides Zato 50-WG (trifloxystrobin)
and Stroby + Delan (kresoxim-methyl + dithianon) were tested in the localities Mihajlovac,
Radmilovac and Landol in 2004 and 2005. Both tested fungicides exhibited high efficacy
in controlling apple scab. There were significant differencies in the efficacies of Flint Plus
(91.3-98.5%) and Zato 50-WG (68.2% and 78.4%); and Tercel (88.7-93.5%) and Stroby + Delan
(77.9% and 82.1%). Our experiments showed that the investigated fungicide mixtures are
highly effective against V. inaqeulais, even under high disease pressure.Ispitivana je efikasnost nekoliko kombinacija fungicida u suzbijanju Venturia inaequalis
na jabuci u poljskim uslovima. U 2005-oj i 2006-oj godini ispitivana je efikasnost Flint Plus
(trifloksistrobin + kaptan) i Tercel (piraklostrobin + ditianon) u odnosu na standardne fungicide
Zato 50-WG (trifloksistrobin) i Stroby + Delan (kresoksim-methil + ditianon) na lokalitetima
Mihajlovac, Radmilovac i Landol. Oba ispitivana fungicida ispoljila su visoku efikasnost
u suzbijanju čađave pagavosti jabuke. Između efikasnosti Flint Plus (91.3-98.5%) i Zato
50-WG (68.2% i 78.4%), i Tercel (88.7-93.5%) i kombinacije fungicida Stroby + Delan (77.9% i
82.1%) zabeležena je statistički značajna razlika. Naši ogledi su pokazali da su ispitivane kombinacije
fungicida visoko efikasne protiv V. inaequalis čak i u uslovima jake zaraze
