Production and characterization of antifungal compounds produced by tomato plants inoculated with Fusarium oxysporum f. sp. lycopersici

Creator:: Danko, Stephen John
Abstract:: The fungitoxicity of acetone extracts from the xylem of Fusarium wilt disease resistant tomato plants (cv. Jefferson) inoculated with Fusarium oxysporum f. sp. lycopersici was greatly influenced by environmental factors. Extracts obtained from plants 1 h after watering were 4-times more toxic than extracts from plants subjected to water stress...

Establishment of Poria carbonica in wood and colonization by basidiomycetes of Douglas-fir utility poles during air seasoning

Creator:: Przybylowicz, Paul
Abstract:: Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...

The development and use of breaking radius and impact bending tests for measuring wood strength loss caused by basidiomycetes isolated from air-seasoning Douglas-fir

Creator:: Sexton, Camille Marie
Abstract:: Douglas-fir utility poles are routinely air seasoned before treatment with chemical preservatives. Basidiomycetous fungi invade these poles and may cause strength loss during air seasoning or later if treatment temperatures are insufficient to kill the decay fungi. The purpose of this study was to develop a rapid test to asses...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1988

Creator:: Morrell, Jeffrey J. and Corden, M. E. (Malcolm E.)
Abstract:: The eighth annual report details continued progress on each of the five objectives. In this year's report, Objectives II and III from previous reports have been combined to reflect the similarity of each effort. Improved fumigants: The previously established field trials continue to demonstrate the superior performance of both chioropicrin...

Evaluating potential decay control agents with a small block test

Creator:: Corden, Malcolm E. and Morrell, Jeffrey J.
Abstract:: A small-scale test was developed to evaluate the ability of fungicides to control decay fungi established in wood. The test, which uses blocks 2.5 x 2.5 x 10 cm, tests the ability of a chemical to migrate from the middle of the block to control a previously established decay fungus,...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1987

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: This seventh annual report outlines our continued progress on each of six objectives. Improved fumigants: We continue to evaluate previously established field tests, which inlicate that chioropicrin continues to protect Douglas-fir poles after 17 years and piling after 12 years. Vorlex treated poles are being gradually recolonized by decay fungi,...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1989

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: Evaluations of previously established field trials indicate that chioropicrin, and Vorlex continue to provide protection to Douglas-fir poles, although the degree of protection is diminishing. Reapplication of Vapam 18 years after the initial application eliminated fungi which had recolonized the poles. Methylisothiocyanate (MITC) continues to protect Douglas-fir poles 12 years...

Methylisothiocyanate as a wood fumigant : fungitoxicity to Poria carbonica in wood and gelatin encapsulation for use in wood products

Creator:: Zahora, Andrew Roy
Abstract:: Experiments were conducted to determine both the influence of wood moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products. The fungitoxicity of MIT was studied by determining the product of...
