Russet Burbank, Shepody, Frontier Russet, and Ranger Russet potatoes were tested for their response under furrow irrigation to PAM-treated irrigation water. The use of PAM was associated with an increase in US Number One tubers for Russet Burbank and Shepody varieties.
Host resistance, both quantitative and qualitative, is the preferred long-term approach for disease management in many pathosystems, including powdery mildew of hop (Podosphaera macularis). In 2012, an epidemic of powdery mildew occurred in Washington and Idaho on previously resistant cultivars whose resistance was putatively based on the gene designated R6....

Studies were conducted in the vicinity of Mount Tolman
on the Colville Indian Reservation in eastern Washington in
order to identify vegetation habitat types of the area.
After field studies were completed, Daubenmire's keys to
habitat types of eastern Washington (1968, 1970) were used
to determine habitat types of the...

Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these...

Tile drainage increases aeration in the root zone of poorly drained soils by
accelerating water movement from the subsurface. Water movement is the main agent
of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by
transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The
detection frequency...

In Kentucky bluegrass (Poa pratensis), Claviceps purpurea, the causal agent of ergot, typically releases ascospores during the early-morning hours, between about midnight and 10:00 A.M., corresponding to time of flowering, when the unfertilized ovaries are most susceptible to infection. During aeromycology studies of C. purpurea in perennial ryegrass (Lolium perenne)...

BACKGROUND: Basic leucine zipper (bZIP) transcription factors are present exclusively in eukaryotes and constitute
one of the largest and most diverse transcription factor families. The proteins are responsible for central
developmental and physiological processes in plants, animals, and fungi, including the pathogenicity of fungal
plant pathogens. However, there is limited...

In August 2012, wilted hop bines were observed in a yard near Seneca Castle, New York,
affecting 10 to 20% of the plants. Affected bines had a dark stem discoloration and wilted
leaves that remained attached after bines were killed. Dark brown to black, erumpent
pycnidia were aggregated in the...
