Abstract:

Bacterial wilt caused by R. solanacearum is one of the most widely spread and destructive disease of ginger (Zingiber officinale Rosc.). An experiment on in vitro studies was carried out to find out the effectiveness of botanicals, bioagents and anti-bacterial chemicals to inhibiting the growth of R. solanacearum. It was revealed from the evaluation that among the nine botanicals tested neem leaf extract was found highly effective with the maximum mean inhibition of 10.31 mm than other botanicals. Among the bioagents Pseudomonas fluorescens (Shivamogga and Bangalore isolate) recorded maximum inhibition zone of 16.85 mm and 16.49 mm respectively, compared to Bacillus subtilis and Trichoderma harzianum. Whereas, results revealed from the evaluation of anti-bacterial chemicals viz., streptocycline + copper oxychloride showed maximum mean inhibition of 29.38 mm followed by streptocycline at 500 ppm (27.07 mm).
