Pseudomonas sp. strain MF30 suppresses Fusarium wilt of tomato in vivo
In a search of bacterial biological control agents, 50 bacterial isolates collected from roots of wild plants in northern Sweden were tested in vivo for suppression of wilt of tomato caused by Fusarium oxysporum f. sp. lycopersici. Tomato plants were sown in 10-cm-diam. pots and after 21 d 7 ml of b...
