| Abstract:
The experiment was carried out to evaluate the effect of different plant activators on some pests including C. michiganensis subsp. michiganensis, the causal agent of bacterial canker of tomato in a greenhouse, naturally infected by the bacterium during growing period including autumn 2002-spring 2003 in Mugla province of Aegean Region of Turkey. The experiment was arranged in a factorial plot design and included 4 different treatments (ISR 2000, consecutive application of ISR 2000 and CropSet, Messenger and water) with 4 replications. Evaluations for bacterial canker were done at the end of growing season by estimation of disease incidence (%) and disease severity index based on 0-5 scale. ISR 2000 and consecutive application of ISR 2000 and CropSet reduced the disease incidence significantly from 87% (water control) to 44% and 42% and the severity index from 4.37 (water control) to 2.45 and 2.56 respectively. The incidence (80%) and severity index (4.55) in Messenger treated plots was not significantly different from these in water control plots. | |
