| Abstract/Contents: | "The incidence and severity of naturally occurring symptoms of Sclerotinia dollar spot was determined in field planting blocks of experimental and commercial germmplasm [germplasm] lines of zoysiagrass. Field observations of disease symptoms were made on zoysiagrass cultural study blocks at TAMU-Dallas during the months of Oct or Nov in 1987 and 1988. Observations of disease severity were made on three replicate cultural blocks with randomized plantings of the commercial and experimental zoysiagrasses. The incidence of dollar spot symptoms was greatest on the variety Emerald and the experimental germplasm line TAES3477. Dollar spot symptoms were also noted on the experimental gerplasm [germplasm] DALZ8502 both years and during one of the two years on DALZ8508 and DALZ8501. During 1988, two hybrid zoysiagrasses, TAES3372 and TAES3477, were added to the cultural blocks. Although TAES3372 did not demonstrate disease symptoms, the hybrid TAES3477 was severely damaged. Zoysiagrasses with fine leaf textures and a high leaf density were generally more dollar spot susceptible than turfgrasses with a coarse leaf texture and low leaf density in the foliar canopy. The experimental variety DALZ8516 with a fine leaf texture and high leaf density was an exception, however; with no dollar spot disease symptoms observed during the two year study." |
