Antagonistic Bacteria for Controlling Fusarium Wilt of Tomato Caused by Fusarium Oxysporum F. Sp. Lycopersici

Four bacterial isolates, namely Serratia marcescens, Burkholderia cepacia, Pseudomonas aeruginosa 1 and P. aeruginosa 2 obtained from the rhizosphere of tomato plants in the field which were antagonistic to the growth of F. oxysporum f.sp. lycopersici in vitro, were evaluated for their ability to su...
