Since its inception in 1985, the Tri-State variety development program has primarily focused on the development of processing and dual-purpose (process and fresh) russets. Recent breeding efforts have focused more on improving genetic resistance to various pests and diseases as a means of lowering production costs. During the past decade,...
This pocket guide highlights fire-resistant plants that thrive in Willamette Valley growing conditions. It recommends groundcovers, perennials, shrubs, woody vines, and trees. There are too many annual plants available to list them all. In general, annuals are considered fire-resistant if they are kept well irrigated.
The potato psyllid, Bactericera cockerelli (Šulc), is

devastating zebra chip disease of potato. To date, four haplotypes
of the potato psyllid have been identified and include
Central, Western, Northwestern, and Southwestern haplotypes.

Due to various reasons the previous investigator decided to pull out the crop level trials from the original experiment designed in 2010 season. However, the irrigation field experiments implemented in the 2010 season continued in 2011, in order to find out the impact of varied deficit irrigation regimes on vine...
