Abstract:

The bacterial leaf blight of rice caused by Xanthomonas oryazae pv. oryzae is the disease of great economics importance in India especially in Bihar. Management of BLB disease can play a vital role in management of rice disease. In the present investigation evolution of different plant extract (botanical) and new chemical on growth of bacteria by poison food technique and sowing by best botanical and new chemical were conducted and antagonistic activity were tested. Three botanical and three new chemical were screened in-vitro for antagonistic activity agent BLB. Among six tested botanical and new chemical isolated again Xanthomonas oryazae pv. oryzae, The aqueous leaf extract of botanicals were effective i.e. Allium sativum, Azadirachta indica and Zingiber officinale were found to be antagonistic towards Xanthomonas oryzae pv.oryzae @ 15% conc. after 48 hours. Three chemicals found effective in reducing severity of BLB were Blitox-50+Streptocycline, Ergon 44.3 SC and Nativo 75WG @50 ppm conc. showed inhibition colony width growth of pathogen by poisons food technique respectively. The seed treatment with six effective i.e. three botanical and three new chemical provide good protection of seed against seed borne pathogen resulting increase seed germination and seedling vigor of rice variety as compare to control.
