Abstract

The field experiments were conducted to evaluate different chemicals, antagonists and botanicals against bacterial blight of rice caused by Xanthomonas oryzae pv. oryzae in South Gujarat. The experiments were laid out in Randomized Block Design at three different locations. streptomycin sulphate + copper oxychloride was found superior over rest of the treatments for reducing bacterial blight intensity and increase grain and straw yield and 1000-grain wt. at all the threelocations and in pooled data. The next effective treatment was copper oxychloride and Pseudomonas fluorescens.
