Biological and molecular characterization of wild type parental and nonpathogenic mutant strains of Pseudomonas syringae pathovars phaseolicola and syringae

Creator:: Bertoni, Gregory
Abstract:: The in planta growth of three wild type strains of phytopathogenic bacteria and three nonpathogenic mutant strains was studied to determine if mutations eliminating the ability of the mutant strains to cause disease had affected their growth in leaf tissue. The mutant strains were obtained by Tn5 mutagenesis of Pseudomonas...

Role of inoculum sources of Botrytis cinerea in the epidemiology of gray mold of snap beans

Creator:: Johnson, Kenneth Bjorn
Abstract:: Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum,...

Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

Creator:: Morris, Mark A.
Abstract:: Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...
