TOWARD ENVIRONMENTALLY SOUND CONTROL OF WATER-MOLD POTATO PATHOGENS ...

In order to determine the potential of a Janthinobacterium (¿AK¿) for control of Phytophthora in potato, we will pursue the following objectives: 1. Generate a large-scale AK culture under optimized conditions to allow enough material for isolation, purification, and characterization of the bacterial compound(s) that inhibit Phytophthora infestans. 2. Confirm that the bacterial compound(s) isolated are active against other Phytophthora, including the potato pathogen P. erythroseptica, responsible for pink rot. 3. Test the viability of the AK bacterium in potted field soil as an initial indicator of the bacterium¿s potential use as a bio-protectant in the field.
