Abstract
Present study deals with laboratory and field efficacy of six antibiotics and three fungi toxicants against Xanthomonas oryzae pv. oryzae (Xoo) to evolve a package of practices for efficient and reliable management of BLB. Among the antibiotics, Streptomycin @ 0.05% found most effective against Xoo with inhibition zone of 27.00 mm which was at par with 26.83 mm zone of inhibition exhibited by Streptomycin @ 0.03%. Streptocycline @ 0.05% was found to be next effective in inhibiting the growth of Xoo and it resulted in 24.25 mm zone of inhibition. In combination of antibiotics + fungi toxicants; maximum inhibition zone (24.42 mm) against Xoo was exhibited by Streptocycline @ 0.3% + Carbendazim @ 0.15% and it was at par with 24.25 mm and 23.67 mm zones of inhibition exhibited by Streptomycin Sulphate @ 0.03% + Copper hydroxide @ 0.25% and Streptocycline @ 0.03% + Copper hydroxide @ 0.25%, respectively. The antibiotics and fungitoxicants found highly effective against Xoo in-vitro were further evaluated against BLB under artificial epiphytotic conditions in field. Combination of streptomycin sulphate @ 0.03% + copper hydroxide @ 0.25% was found most effective with least BLB severity (57.45%), highest yield (36.53 q/ha) and 1000 grains weight (28.36g). Streptocycline @ 0.03% + copper hydroxide @ 0.25% was found next effective combination against BLB with 59.26% severity, 35.24 q/ha yield and 27.43g 1000 grain weight. These combinations were significantly superior to the respective similar parameters observed in recommended control measure i.e. spray of combination of Copper Oxy-chloride @ 0.25% + Streptocycline @ 0.01%.
