Evaluation of biocontrol agents for managing root diseases on hydroponically grown tomato

Abstract

The effect of the bacterial strain Pseudomonas fluorescens 5.014 together with three commercial biocontrol products (Binab T, Gliomix and Mycostop) against root diseases caused by Pythium ultimum, P. aphanidermatum, Phytophthora cryptogea and Fusarium oxysporum f. sp. radicis-lycopersici was evaluated in the climate chamber for 4 weeks. The results indicated efficiency of all the biocontrol strains against P. ultimum and P. aphanidermatum. Effectiveness against F. oxysporum f. sp. radicis-lycopersici was only shown by the commercial products. BinabT and Mycostop were also effective against P. cryptogea. A growth promoting effect was indicated by the biocontrol strains after their application to the system.
