Genetic Characterization of Binucleate Rhizoctonia Species Causing Web Blight on Azalea in Mississippi and Alabama.
Web blight on containerized azalea is an annual problem for commercial nurseries during summer months in the southern United States. Losses to web blight are associated with the cost of fungicide… Expand
Ultrastructure of the Penetration and Infection of Pansy Roots by Thielaviopsis basicola.
ABSTRACT Transmission electron microscopy was used to study the penetration and infection of pansy roots by Thielaviopsis basicola. Events observed in 7- to 10-day-old roots produced on moist filter… Expand
Toxicity Responses of Herbaceous and Woody Ornamental Plants to Chlorine and Hydrogen Dioxides
Regular and excessive rates of chlorine dioxide (ClO2) and hydrogen dioxide (H2O2) were sprayed five times at 3-day intervals on eight bedding plant and nine shrub species to determine if plant… Expand
Chemical disinfestation of greenhouse growing surface materials contaminated with Thielaviopsis basicola
Sodium hypochlorite and captan significantly reduced propagule viability of Thielaviopsis basicola on polypropylene fabric, pressure-treated wood, and galvanized metal hardwarecloth surfaces that had… Expand
Activity of Chlorine Dioxide in a Solution of Ions and pH Against Thielaviopsis basicola and Fusarium oxysporum.
Chlorine dioxide (ClO2) is a disinfestant used to control pathogens in water. To determine if interactions between inorganic ions and pH levels effect ClO2 activity in vitro, concentrations of ClO2… Expand
Evaluation of Methods to Detect Fruit Infected by Monilinia vaccinii-corymbosi in Mechanically Harvested Rabbiteye Blueberry.
Blueberry fruit infected by Monilinia vaccinii-corymbosi (causal agent of mummy berry disease) are unfit for processing because of the formation of hardened structures (pseudosclerotia) within them.… Expand
Plant Spacing Effects on Microclimate and Rhizoctonia Web Blight Development in Container-grown Azalea
Rhizoctonia web blight, caused by Rhizoctonia solani and binucleate Rhizoctonia spp., is an annual problem in compact cultivars of container-grown azalea (Rhododendron spp.) in the Gulf Coast states.… Expand
Phytophthora mississippiae sp. nov., a New Species Recovered from Irrigation Reservoirs at a Plant Nursery in Mississippi
A previously unknown Phytophthora species was recovered from irrigation water in Mississippi. This novel species produced both nonpapillate and semipapillate sporangia, and catenulate hyphal… Expand

Spore germination, infection structure formation, and colony development of Erysiphe pulchra on glass slides and leaf disks of a susceptible flowering dogwood line were examined using light and… Expand
Effect of Temperature on Sporulation of Botryosphaeria dothidea, B. obtusa, and B. rhodina.
Three Botryosphaeria spp. were grown on autoclaved apple and peach stems in cotton-plugged tubes with constant moisture at 6, 12, 18, 24, and 30°C to determine the effect of temperature on… Expand
