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....

Lodging control and yield enhancement in Morex spring barley with paclobutrazol treatment

Creator:: Morrison, Laura A.
Abstract:: Lodging in cereals can cause significant decreases in yield. It is both a problem in susceptible cereal cultivars with a tall-stemmed, weak-strawed growing habit and in lodging-resistant cereal cultivars when they are grown under high-nitrogen, high-moisture regimes. Plant growth regulators (PGR's) are chemical growth retardants that offer a method of...

Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

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...

Thinning and urea fertilization effects on emerging grand fir (Abies grandis) foliage and growth of western spruce budworm (Choristoneura occidentalis) larvae

Creator:: Savage, Thomas J.
Abstract:: The objective of this study was to determine how the balance of carbon to nitrogen in a grand fir ecosystem affects the chemistry of emerging grand fir foliage and the growth of western spruce budworm larvae. Forest plots in the grand fir zone of eastern Oregon were thinned, thinned and...

Inheritance of resistance to the lentil strain of pea seedborne mosaic virus in Pisum sativum L.

Creator:: Kasimor, Kathryn T.
Abstract:: The inheritance mode of pea-resistance to the Lentil Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was studied. In addition, commercial pea cultivars, Plant Introduction (P.I.) lines and Oregon State University (OSU) breeding lines were tested for susceptibility to this virus. These lines were also tested for their reaction to Bean...

Fusarium root disease of western white pine seedlings at the Coeur d'Alene Nursery, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Root disease of 2-0 western white pine seedlings occurred at the Coeur d'Alene Nursery in 1982 within seedbeds fumigated with methyl bromide and chloropicrin. Although losses were not substantial, there were several groups of dead seedlings within affected seedbeds. Fusarium oxysporum was most often isolated from diseased roots. Other Fusarium...
