The effects of fungicides were studied on two isolates of Sclerotinia homoeocarpa that differed in fungicide sensitivity. Concentrations of benzimidazole (benomyl and thiophanate-methyl), demethylation inhibitor (fenarimol, propiconazole, and triadim

Components of resistance to Rhizoctonia solani in the tall fescue cultivars Kentucky 31 (moderately resistant) and Mojave (susceptible) were evaluated under controlled environmental conditions. Size and expansion rate of foliar lesions were recorded

In response to reports of reduced efficacy of propiconazole for control of dollar spot, isolates of Sclerotinia homoeocarpa were collected from several locations in Georgia and tested for sensitivity to propiconazole and other demethylation-inhibitin

An unusual and undescribed foliar blight of tall fescue was observed in a home lawn and in turf grass research plots near Griffin, GA in May and June, 2000 and 2001. Isolation from lesions yielded mycelium of a basidiomycete with hyphal characteristi

The components of resistance in tall fescue to Magnaporthe grisea, the causal agent of gray leaf spot, were measured in growth chamber experiments. Cultivars ranging in susceptibility to M. grisea were selected: ‘Kentucky 31’ (susceptible), ‘Re

Six replicate trials were conducted to determine the short-term temporal dynamics and the effects of foliar applications of nutrients on the phylloplane yeast community of tall fescue ( Festuca arundinacea Schreb.). In each trial, 2% sucrose + 0.5% y

Four experiments were conducted to assess the effect of foliar applications of various nutrient solutions on the phylloplane yeast community of tall fescue (Festuca arundinacea Schreb.). In the first three experiments, increasing concentrations of su

The ability of yeasts to attach to hyphae or conidia of phytopathogenic fungi has been speculated to contribute to biocontrol activity on plant surfaces. Attachment of phylloplane yeasts to Botrytis cinerea, Rhizoctonia solani, and Sclerotinia homoeo

Populations of Magnaporthe grisea associated with tall fescue and St. Augustinegrass in Georgia were analyzed for mating type distribution and fertility status in 1999 and 2000. A polymerase chain reaction based assay for mating type was developed to
