Evaluation of Fusarium graminearum Associated with Corn and Soybean Seed and Seedling Disease in Ohio.
Results indicate that F. graminearum is an important pathogen of both corn and soybean seed and seedlings in Ohio, and that continued use of fludioxonil potentially may select for less sensitive isolates of F. GramInearum. Expand
Characterization of Pythium spp. Associated with Corn and Soybean Seed and Seedling Disease in Ohio.
Cool, moist conditions in combination with minimum tillage, earlier planting, and recent shifts in commercial fungicide seed-treatment active ingredients have led to an increase in corn (Zea mays)… Expand
Infection of Soybean Seed by Fusarium graminearum and Effect of Seed Treatments on Disease Under Controlled Conditions.
There are limited choices in fungicide seed treatments for managing this seedling disease, and it is possible that shifts in seed treatment products may have played a role in the recent emergence of this soybean pathogen. Expand
Association of soil chemical and physical properties with Pythium species diversity, community composition, and disease incidence.
A high-throughput baiting and identification process identified more than 7,000 isolates of Pythium from 88 locations in Ohio and formed five communities, and significant differences were observed in disease incidence, as well as soil pH, calcium, magnesium, and cation exchange capacity between communities.

Population Structure of Geosmithia morbida, the Causal Agent of Thousand Cankers Disease of Walnut Trees in the United States
The large number of haplotypes observed and the genetic complexity of G. morbida indicate that it evolved in association with at least one Juglans spp. Expand

This research provides a valuable genetic resource for research into the genus Ophiognomonia, demonstrates a framework for the rapid and cost‐effective discovery of SNP markers in non‐model organisms and should prove especially useful in the case of asexual or clonal fungi with limited genetic variability.

The new family Septorioideaceae, within the Botryosphaeriales and Septorioides strobi as a new species associated with needle defoliation of Pinus strobus in the United States.
A morphological description and phylogenetic analysis show that this putative new species is distinct from S. pini-thunbergii and S. strobi, and comprise a new family within the order Botryosphaeriales, which is recognized as Septorioideaceae fam. Expand
Extent and severity of Caliciopsis canker in New England, USA: an emerging disease of eastern white pine (Pinus strobus L.).
To assess the extent and severity of Caliciopsis canker and to explore environmental variables associated with disease to identify areas at risk of damage, 58 sites across New England with >75% P. strobus basal area in public lands were surveyed. Expand
De novo genome assembly of Geosmithia morbida, the causal agent of thousand cankers disease
The first draft genome of G. morbida serves as a valuable tool for comprehending the underlying molecular and evolutionary mechanisms behind pathogenesis within the Geosmithia genus. Expand
