Detailed explanation-1: -Bacterial leaf blight of rice (BB) is a disease caused by the Gram-negative bacterium Xanthomonas oryzae pv.
Detailed explanation-2: -Bacterial blight is caused by Xanthomonas oryzae pv. oryzae. It causes wilting of seedlings and yellowing and drying of leaves.
Detailed explanation-3: -Background: Xanthomonas campestris pv. campestris (Xcc) (Pammel) Dowson is a Gram-negative bacterium that causes black rot, the most important disease of vegetable brassica crops worldwide.
Detailed explanation-4: -Rice leaf blight, which is caused by the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo), results in huge losses in grain yield.
Detailed explanation-5: -oryzae were made. Six chemicals (Phytomycin, Streptomycin, Blasticidin, Kasumin, Tricyclazole, and Sumithione) arrested the growth of bacteria in vitro and produced good inhibition zone. In vivo condition, however, only three chemicals (Blasticidin, Kasumin and Streptomycin) controlled the disease to a certain extent.
