[Isolation and screening of beneficial endophytic bacteria to control bacterial ring rot of potato].
One hundred and thirty-three bacterial strains were isolated from inner tissue of potato tubers collected from Datong, Taiyuan and Inner Mongolia Autonomous regions. On the basis of antagonistic examination in vitro, greenhouse and field tests, five strains named as 069, 085, 110, 116 and 118 were chosen for their suppression of bacterial ring rot or their growth promotion. Strain 118 is an endophytic bacterium with three effects of colonization, growth promotion and suppression of the pathogenic bacteria, showing good prospects for commercial use.
