Abstract

A Pestalotiopsis sp. identified as the major pathogen causing leaf blight disease of Syzygium cumini was isolated from naturally infected leaf samples of S. cumini collected from forest nurseries of the Mysore district, India. The fungus was pathogenic on 4-month-old seedlings, which exhibited leaf blight symptoms within 15 days of inoculation. The effects of five systemic and two contact fungicides were evaluated against the pathogen in vitro using the poison food technique. Among the seven fungicides studied in vitro only two systemic fungicides namely, Bavistin and Roko were proven to be effective against Pestalotiopsis sp. at concentrations of 50, 100 and 150 mg/L; these fungicides showed 100% growth inhibition and nil fungal growth. The effectiveness of systemic fungicides was higher than that of contact fungicides. Thus, the present study recommends the use of Bavistin and Roko at a minimal concentration of 50 mg/L for maximum inhibition of Pestalotiopsis sp.
