| Abstract/Contents: | The sensitivity of 17 Pythium species to six fungicides was determined in vitro. Isolates (single or multiple) of all species were obtained from roots and stolons of creeping bentgrass. Fungicides were incorporated into corn meal agar at 0, 1, 10 or 100 ug/ml a.i. Agar plugs containing mycelium were placed on the medium and radial growth measured after 48 hr. Fungicides tested were: etridiazole, metalzxyl, mancozeb, metalaxyl + mancozeb, fostyl-Al, chloroneb, and propamocarb. LD50 values varied with Pythium sp. and fungicide. All species were sensitive to etridiazole, with LD50 values typically between 1 and 2 ug/ml. None of the species were sensitive to fosetyl-Al in vitro. LD50 values for other fungicides was species dependent. For example, LD50 values for metalaxyl ranged from <1 to >100 ug/ml across species. The role of fungicide sensitivity in the ecology of Pythium spp. and Pythium diseases on golf greens will be discussed." |
