Author(s): Balanagouda Patil, Jagadeesh GB, Karegowda C, Seema Naik and Revathi RM
Abstract:
Bacterial leaf blight (BLB) is considered as a major threat to rice production because of its wide spread, distribution and its destructiveness under favourable conditions. The disease is caused by Xanthomonas oryzae pv. oryzae is one of the most destructive disease in irrigated and rain fed environment in Asia and cause considerable loss. Thus, a field trial was conducted during Kharif 2016 at AHRS, Bavikere to know the efficacy of different commercially available antibacterial chemicals and bio-agents against the bacterial leaf blight of rice. Results indicated that, streptocycline + copper oxychloride combined treated plots showed the lowest per cent disease incidence of 22.33 per cent followed by bacterinashak, agrimycin 100, kasugamycin and the highest disease severity was recorded in control (55.53%). Highest grain yield of 56.49 q/ha was recorded in streptocycline + copper oxychloride, which was significantly superior over all the treatments, followed by bacterinashak (54.24 q/ha), kasugamycin (50.13 q/ha) and agrimycin 100 (49.38 q/ha). The least grain yield was obtained in Bacillus subtilis (41.33 q/ha).
