Taro leaf blight disease, caused by Phytophthora colocasiae is a major limiting factor in Taro production worldwide. Knowledge of resistance of Taro genotypes against the pathogen is very important for effective management of Taro leaf blight disease. Taro leaf blight disease was surveyed in 27 Taro growing farmers’ fields of Wolaita and Kembata Tembaro Zones of Southern Ethiopia during 2017. A total of 15 representative Phytophthora colocasiae isolates were isolated at Areka Pathology Laboratory. This isolates virulence test was carried out by using detached leaf disc method. From the 15 P. colocasiae, isolate A, collected from Sodo Zuria produced extensive necrotic lesions on the leaf and the pathogen was found to be most virulent when compared with the other fourteen isolates. Then after most aggressive P. colocasiae isola.. Read More»
