White rot, caused by Sclerotium cepivorum, is a serious disease that causes significant yield losses in Allium production. The pathogen persists in soil as sclerotia, which germinate in response to sulfur compounds in Allium root exudates. This study was aimed at investigating the potential of early-terminated Allium bait crops to...
1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.

The role of small secreted peptides in plant defense responses to viruses has been seldom investigated. Here, we report a role for potato (Solanum tuberosum) PIP1, a gene predicted to encode a member of the PAMP-induced peptide (PIP) family, in the response of potato to potato virus Y infection (PVY)....
Micronutrient deficiency, also known as the hidden hunger, affects over two billion people worldwide. Potato is the third most consumed food crops in the world, and is therefore a fundamental element of food security for millions of people. Increasing the amount of micronutrients in food crop could help alleviate worldwide...

Under July 1, 1972 - June 30, 1973 cost levels for the Little White Salmon and Willard National Fish Hatcheries, small budget reductions made by reducing expenditures for fish food resulted in sharp increases in average total cost per pound of salmon produced.
Experiments were conducted to determine survival, growth, and accumulation of HEOD (major component of dieldrin) in the tissues of steelhead trout (Salmo gairdneri) embryos, alevins, and fry exposed to dieldrin concentrations ranging from 0.012 to 52 ppb. The fish were held in specially designed exposure chambers provided with continuously renewed...

Nearly complete sequences of RNA-CP and 3'-proximal RNA-TGB were determined for 43 samples of potato mop-top virus (PMTV) originating from potato tubers and field soil from Sweden, Denmark and the USA. The results showed limited diversity and no strict geographical grouping, suggesting only a few original introductions of PMTV from...

This publication describes raspberry cultivars, including red, yellow, black, and purple types. It explains the difference between floricane-fruiting and primocane-fruiting cultivars, includes information on commercial value, and identifies which cultivars work well for home gardens.
Canopy management is critical to successful winegrape production. Canopy management begins with vineyard design and includes decisions about soil, water, cover cropping, fertilization and weed control. Shoot thinning, leaf removal, hedging and crop thinning are also part of canopy management.
Vineyard design and management methods that create vine balance will help sustain productive yields, achieve desired fruit quality and maintain vine health. Different climates across Oregon will affect strategies for achieving vine balance, but the basic approach is the same everywhere.
In 1982, Oregon State University Extension Service was again asked to make a winegrape acreage survey in Oregon. Winegrape acreage is currently increasing dramatically and the Table Wine Research Advisory Board (TWRAB) is interested in keeping track of these changes.
In 1981 Extension made a survey of acreages by county...
