Abstract

A survey was conducted at different rice growing regions of Tamil Nadu such as Erode, Tanjore and Coimbatore. Among the areas surveyed the maximum disease incidence was recorded at Tanjore in the rice variety ADT 54 with the percent disease incidence of 50.23%. Initially one bacterial pathogen Xanthomonas oryzae pv.oryzae was isolated in nutrient agar medium from the leaves having characteristic symptom. Totally 10 isolates of Xoo were collected from three different regions of Tamil Nadu. On isolating the pathogen the colonies are found to be well separated with slimy yellow color and mucoid growth.
