Abstract:: Population size of Clavibacter michiganensis subsp. sepedonicus in potato cv Russet Burbank and plant response as affected by drought were assessed in a greenhouse experiment. Water deficit stress and no stress treatments, and inoculum densities of 0 or 2 X 10⁷ cfu C. m. sepedonicus/seed piece were arranged factorially. Stem...

Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Abstract:: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10...

Abstract:: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...
