Abstract :Effects of a growth regulator (Prehexadione-Ca) with a plant activator+systemic fungusit (Benzothiadiazole + Metalaxyl) combination on shoot blight phase of fire blight caused by Erwinia amylovora were investigated on Ankara, Santa Maria, Williams, Deveci, Rıza Bey pear cultivars in vivo conditions. According to the data obtained; Streptomy-cin gave the highest protection both in greenhouse (68,85-95,70%) and in the field (95,60-98,08%) and it was followed by Prohexadione-Ca (greenhouse 16,50-25,20% and field 17,22-27,58%), Benzothiadiazole+Metalaxyl (greenhouse 12,27-16,29%, field 6,38-17,21%) and Tenn Cop 5 E (greenhouse 6,57-14,38%, field 6,51-15,95%). In addition, the effects of this chemicals on shoot growth of pear varieties were also determined.Keywords : Erwinia amylovora, Prohexadione-Ca, Benzothiadiazole+Metalaxyl, Ateş yanıklığı
