Abstract :Effects of a growth regulator insert ignore into journalissuearticles values(Prehexadione-Ca); with a plant activator+systemic fungusit insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(68,85-95,70%); and in the field insert ignore into journalissuearticles values(95,60-98,08%); and it was followed by Prohexadione-Ca insert ignore into journalissuearticles values(greenhouse 16,50-25,20% and field 17,22-27,58%);, Benzothiadiazole+Metalaxyl insert ignore into journalissuearticles values(greenhouse 12,27-16,29%, field 6,38-17,21%); and Tenn Cop 5 E insert ignore into journalissuearticles values(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.
