Utilization of organic and mineral amendments to control potato bacterial wilt disease

Potato brown rots known as bacterial, wilt disease, is a serious disease causing problems is ill the warm regions of the tropics and subtropics. It has been reported also in cool climates of North Western Europe. Primary infection by Ralstonia solanacearum bacteria occurs through roots or the stolons as soil born disease. This study carried Out to study the effect of organic matters mid mineral fertilizers as soil amendments on bacterium population of Ralstonia solanacearum and disease severity (virulent and avirulent forms), Wider artificial inoculation condition. Result indicated that bacterium population mid disease severity were significantly reduced when treated with the soil amendments "Garlic" and "Potassium Sulfate" after 90 days ill comparison to the control treatment. Additionally, it was clear From the experiment that organic matters were more successful in the virulent forms reduction.
