Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Compost teas and compost amended container media for plant disease control

Creator:: Scheuerell, Steven J.
Abstract:: The primary goal of this dissertation research was to assess the use of compost for the control of several foliar and soil borne diseases commercially important in the Pacific Northwest. The use of compost teas to control of gray mold (Botrytis cinerea) on geraniums, powdery mildew (Podosphearapannosa var. rosae), rust...

An evaluation of the efficacy of hot water-chemical treatments to clean styroblock containers, Champion Timberlands Nursery, Plains, Montana

Creator:: James, Robert L., Woollen, R. L., and United States. Forest Service. Northern Region
Abstract:: Treating styroblock containers in hot water (68°C) with a very dilute bleach and detergent solution effectively reduced populations of Fusarium and Cylindrocarpon spp., two potential root pathogens of containerized conifer seedlings. However, the treatment did not significantly reduce levels of Phoma (another potential pathogen) nor saprophytic Penicillium and Alternaria spp....

Effects of inoculations with pathogenic and beneficial microorganisms and ammonium of nitrate fertilization on Easter lily growth

Creator:: Valenciano Mora, Jose Roberto
Abstract:: Although chemical fungicides are commonly used to control fungal soil-borne diseases of Easter lilies, Lilium longiflorum Thunb., in field production and greenhouse forcing, cultural and biological controls may be alternatives or complementary to chemicals for control of pathogens. The influence of inoculations with beneficial, symbiotic, and biocontrol microorganisms to enhance...

Effects of radio frequency waves on fungal colonization of styroblock containers

Creator:: James, Robert L., Trent, Andy, United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Fungal pathogens tend to accumulate within styroblock containers, which are reused to produce successive crops of container-grown seedlings. Most nurseries treat reused containers by immersing them in hot water for varying time periods. The efficacy of radio frequency waves (RFs) to reduce levels of selected groups of fungi within styroblock...

Fungal colonization of styroblock containers Plum Creek Nursery, Pablo, Montana

Creator:: James, Robert L. and Gilligan, Carma J.
Abstract:: An evaluation of the efficacy of steam treatment on reducing levels of Fusarium, Cylindrocarpon, and Trichoderma within styroblock containers was conducted at the Plum Creek Nursery in Pablo, Montana. Although levels, of both Fusarium and Cylindrocarpon were significantly reduced by cleaning, relatively high populations of both these fungi persisted after...

Needle diseases in Oregon coast range conifers

Creator:: Oregon State University. Extension Service, Kavanagh, Kathleen L., 1955-, Filip, Gregory M., and Rogers, William Reinhold
Abstract:: This publication discusses the environmental requirements of needle diseases, their potential impact on tree vigor, when disease levels signal a problem, and what you can do to minimize damage.

Spatial analysis of Phellinus weirii infection centers in the central Cascades of Oregon : inferring ecological processes from patterns

Creator:: Lattin, Peter D.
Abstract:: This study was conducted to investigate why root disease centers east of the Cascade crest tend to be larger in diameter and more abundant than their counterparts to the west, within subalpine forest stands of central Oregon. The trend in a 290 km² study area appeared opposite of what was...

Effect of scald (Rhynchosporium secalis) on yield and yield components of twelve winter barley (Hordeum vulgare) genotypes

Creator:: Zencirci, Nusret
Abstract:: The effects of scald epidemics, induced by Rhynchosporium secalis (Oud.) Davis, on the yield and quality of winter malting barley have not been reported. The principal objective of this investigation was to assess yield and quality losses in resistant and susceptible winter barley genotypes in diverse environments of the Pacific...
