The results indicated efficiency of all the biocontrol strains against <i>P. ultimum</i> and <i>P. aphanidermatum</i>. Effectiveness against <i>F. oxysporum</i> f. sp. <i>radicis-lycopersici</i> was only shown by the commercial products. BinabT and Mycostop were also effective against <i>P. cryptogea</i>. A growth promoting effect was indicated by the biocontrol strains after their application to the system. 收起
