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.
Zusammenfassung
Die Wirkung des Bakterienstamms Pseudomonas fluorescens 5.014 und der drei kommerziell produzierten Antagonisten Binab T, Gliomix und Mycostop gegeüber den Wurzelerregern Pythium ultimum, P. aphanidermatum, Phytophthora cryptogea und Fusarium oxysporum f. sp. radicis-lycopersici wurde über 4 Wochen in Klimakammern untersucht. Alle Antagonisten wirkten gegenüber P. ultimum and P. aphanidermatum, während nur die drei kommerziellen Produkte F. oxysporum f. sp. radicis-lycopersici kontrollierten. BinabT and Mycostop wirkten auch gegenüber P. cryptogea. Eine wachstumsfördernde Wirkung der Antagonisten wurde ebenfalls beobachtet.
