Determinación del nivel de inóculo primario de Pseudomonas solanacearum en suelos con infestación natural

Several methods were tested for detecting the residual inocuhnn of Pseudomonas solanacearum, Race 1, in inceptisols at Turrialba, Costa Rica, where lire bacterium is apparently endemic Planting healthy potato tubers in soil samples in the greenhouse, then using plant wilt as indicator of the pathoge...
