| Abstract/Contents: | "Yellow tuft, i.e., downy mildew caused by Sclerophthora macrospora (Sacc.) Thirumalachar, C. G. Shaw, and Narasimhan, was observed in July and August of 1992 in Kentucky bluegrass (Poa pratensis L.) sod fields in Illinois. The sod was 18 mo old and growing on soil used continuously for sod production the previous 5 yr. Tufts (5-15 cm in diameter) of diseased turf were observed at three field locations and collectively represented approximately 3 ha (7 acres); about 10% of that turf was affected. Excessive soil moisture for 4 wk and daily air temperatures ranging from 15 to 26 C preceded disease development. Distribution of diseased tufts of grass reflected the direction of mower movement in the fields. The tufts of yellow grass grew faster than adjacent turf, and there was extensive proliferation of shoots from crowns. Lower leaf, crown, and root tissues were heavily colonized by intercellular hyphae. Oospores were abundant in infected crown and root tissues. The hyphae, oospores, and sporangia matched those previously described by Dernoeden and Jackson (1)." |
