ESTIMATION OF ANTIBIOTICS AND SYNTHETIC CHEMICALS TOWARDS BACTERIAL WILT OF POTATO CAUSED BY RALSTONIA SOLANACEARUM

Abstract

Bacterial wilt of potato caused by Ralstonia solanacearum is most severe bacterial disease effecting potato production worldwide.In present research, the effect of different chemicals [Score(24.51%), Topsin-M (70%), Cabrio (60%), Fossi l(29%), Milvet (80%), Forum Top (53%), Excel(80%), Evcin (80%), Electus Super (30%) and Copper Hydroxide (52.4%) and antibiotics [Quinosel (10%), Novamox -LA (15%), Neflox(30%), Gentam(20%), Velocef (29%), Rithmo (44%), Cefcom (52.4%), Cefstar(52.41%) were evaluated against R. solanacearum under in-vitro conditions through inhibition zone technique and then, the combined effect of most effective chemical Score and antibiotic Quinosel was evaluated in-vivo conditions. The findings of the current study suggest that certain chemicals and antibiotics may be considered as an effective tool for the management of R. solanacearum in potato cropping system.
