Efficacy of agro-chemicals for management of bacterial blight of pomegranate

Bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. punicae is a wide spread disease affecting pomegranate production in Punjab. Field experiment was conducted for its management at Punjab agricultural university, ludhiana during 2013. Four sprays of the agro-chemicals were done at 15 days interval starting from mid June to end July. Blitox 50 WP (0.3%) + streptocycline (250 ppm) proved most effective in reducing the per cent disease index and provided maximum disease control. Kocide 77 WP (0.25%) + streptocycline (250 ppm) was the next best treatment. The fruit yield in Blitox + streptocycline and Kocide + streptocycline was at par but differed significantly to all the other treatments. Therefore, sprays of Blitox + streptocycline and Kocide + streptocycline were quite effective for managing bacterial blight of pomegranate.
