Métodos de isolamento de bactérias do filoplano de tomateiro visando populações específicas e implicações como agentes de biocontrole
[Isolation methods of tomato phylloplane bacteria aiming specific populations and implications as biocontrol agents]
Fitopatologia Brasileira 29 (6), 638-643
Abstract: In a process of selecting tomato (Lycopersicon esculentum) phylloplane bacteria with potential for controlling aerial diseases of this crop, different isolation methods were used to obtain the isolates from total leaf surface and also from protected sites of the phylloplane. Three hundred isolates were tested in vivo for their ability to control diseases caused by Alternaria solani, Pseudomonas syringae pv. tomato and Phytophthora infestans. The results demonstrated a predominance of antagonists in the total population originating on the surface of the leaflets harvested from the upper leaves of the plants. Only one selected antagonistic isolate obtained from the lower leaves was recovered from the protected sites of the phylloplane and/or was stress tolerant.
