| Abstract/Contents: | "Pathogenicity was studied in pre- and post-emergence tests on bentgrass seedlings at 28C with 33 Pythium spp. isolated from bentgrass and other turfgrasses with symptoms of root and crown rot in NC. In pre-emergence tests 13 species were highly or moderately pathogenic. In post-emergence tests P. arrhenomanes, P. aristosporum, P. aphanidermatum, P. graminicola, P. myriotylum, P. tardicrescens, P. vanterpoolii and P. volutum were highly pathogenic. P. dissotocum, P. irregulare, P. multisporum, P. paroecandrum, P. splendens, P. sylvaticum, P. ultimum (var. sporangiiferum, var. ultimum), and P. violae were moderately pathogenic. Highly and moderately pathogenic species colonize the epidermis and cortex inter and intracellularly causing severe or mild disease. In tests at 16, 28 and 32C, the higher temperatures favored pathogenicity of most species." |
