| Abstract/Contents: | "Stenotrophomonas maltophilia C3 was found in previous studies to provide field control of leaf spot in tall fescue (Festuca arundinacea Schreb.), caused by Bipolaris sorokiniana (Sacc.) Shoemaker. Chitinases and other lytic enzymes were involved in antagonism by C3 in the laboratory, but the spatial distribution of C3 detected on field turf sugggests that field control cannot be explained entirely by antagonism through lytic enzymes. In this study, strain C3 inhibited the germination of B. sorokiniana conidia on tall fescue leaves and suppressed the development of Bipolaris leaf spot possibly by inducing localized host resistance. When live or heat-killed cells of C3 were applied to foilage, pathogen conidial germination on foilage, leaf spot incidence and leaf spot severity were reduced, but live cells were more effective than dead cells. Application of C3 cells to tall fescue roots had no effect on conidial germination on leaf surfaces or disease development. Application of live C3 cells to any portion of a leaf reduced germination of pathogen conidia on the entire surface of the treated leaf. Germination of conidia on non-treated leaves of the same shoot, however, was unaffected. The possibility of localized induction of resistance, coupled with antagonism, could contribute to effective disease control using C3 without requiring uniform colonization of leaves." |
