Abstract

The antagonistic capacity of the bacterium Burkholderia cepacia for controlling diseases caused by the Oomicete pathogen Phytophthora capsici in pepper plants was studied. Its effect on seed, leaves and roots was evaluated by measuring the reduction in leaf spot and root rot caused by the pathogen and its influence on plantlet germination and growth. The antagonistic capacity of B. cepacia was assessed in vitro by confronting the bacterium and P. capsici, while its innocuousness was confirmed by adding to seeds and plantlets in in vivo trials. When the bacteria preparation was added to plants inoculated with the pathogen, it reduced root rot by 37% in field conditions and by 55,6% in the controlled conditions of greenhouse. The results obtained suggest that B. cepacia may be considered for use as an antagonist for the biocontrol of the soil fungi which attack peppers.
