Abstract

As a part of a broader program for management of bacterial blight of cotton, the cultivars, the application of bactericides, chemicals and organics were evaluated. Among cultivars JK (42 – 44) was found to be resistant and the cultivar LRA-5166 remained highly pathogenic. Seeds of cotton cv. LRA 5166 and JK (42 – 44) inoculated with Xanthomonas campestris pv. malvacearum were subjected to different treatments in the greenhouse and field experiments to evaluate seed germination and their resistance to blight and in improving seed germination in cotton, respectively. Hot water treatment inhibited the incidence of bacterial blight to a lesser extent and the germination was also poor. Organic treatments exhibited better performance in increasing germination and in reduction of blight disease, which was significantly superior over all other treatments by 72, 67, 66 and 68%, respectively. Whereas in the case of chemical treatment, the incidence of blight was reduced to a greater extent and germination was affected.
