Incidence of Phytophthora Root Rot of Fraser Fir in North Carolina and Sensitivity of Isolates of Phytophthora cinnamomi to Metalaxyl.
Although incidence of Phytophthora root rot has not increased in the state compared to a survey done in 1976 to 1977, the disease continues to limit production of Fraser fir in North Carolina.
Formation of ectomycorrhizae on Pinustaeda seedlings exposed to simulated acidic rain
Responses of ecetomycorrhiza formation and associated shoot growth to acidity of simulated rains suggest that rains of intermediate acidity (pH 4.0 and 3.2) inhibited ectomycorRhiza formation, or that increased soil acidity or other factors induced by rains at pH 2.4 enhanced ectomy Corrhizae formation.
Phylogenetic and phenotypic characterization of Fomes fasciatus and Fomes fomentarius in the United States
It is found that mean basidiospore size is significantly larger in F. fomentarius and represents the most informative morphological character for delineating the species.
Temporal and Spatial Epidemiology of Phytophthora Root Rot in Fraser Fir Plantations.
All sources of inoculum including infected planting stock, inoculum in soil, infected trees, and contaminated equipment were equally important in epidemics of Phytophthora root rot in Fraser fir and dispersal of P. cinnamomi.
Effect of fertilization on production of epigeous basidiocarps by mycorrhizal fungi in loblolly pine plantations
Basidiocarps of 39 epigeous species of proven or potential mycorrhizal fungi were found in three fertilized Pinus taeda plantation s during 1972 and 1973. The largest numbers of basidiocarps on all...
Susceptibility of Cultivars and Hybrids of Kousa Dogwood to Dogwood Anthracnose and Powdery Mildew
None of the taxa were found to be immune to dogwood anthracnose, yet there was considerable variation in resistance to the disease.
Cercospora Caricis from Cyperus Esculentus (Yellow Nutsedge): Morphology and Cercosporin Production
The objectives of this study were to compare the North Carolina isolates of the fungus with C. caricis collections and to determine if cercosporin was produced in culture, and to compare leaves collected in 1986 from Johnston and Wake Counties in North Carolina.
