Abstract :Apple scab, caused by insert ignore into journalissuearticles values(Venturia inaequalis insert ignore into journalissuearticles values(Cke); Wint.); is a serious and most destructive fungal disease of apple trees in Turkey. Managing a lot of plant diseases is possible enhancement of host resistance by sistemic acquired resistance insert ignore into journalissuearticles values(SAR); inducers according to last investigations. With this aim, experiments were conducted in Isparta Province, Horticultural Research Institute of Eğirdir to evaluate the efficacy of alone plant activators and fungicides and combinated applications for control possibilities of the apple scab on Malus domestica cv. Golden in 2004. This chemicals were applicated during the early phase plant growth and three times. According to data, firstly two application Isr- 2000 and last application Chorus from three spraying, Isr- 2000+Chorus combination was provided the most effectiveness on ratio 73.10%. It was followed by Isr- 2000+Candit combination insert ignore into journalissuearticles values(67.81%);. In the fungicides, alone Chorus insert ignore into journalissuearticles values(58.77%); and alone Candit insert ignore into journalissuearticles values(55.74); were given moderate effectiveness in three times applications. Obtained results were showed that alone application of Isr- 2000 was given high effectiveness compared with Crop set. However disease severity was situmulated by alone and only one application of Crop set with compared control trees. Results of plant activators were encouraged, indicating a reduction of apple scab on disease control.
