Chemical applications for control of armillaria root rot of Ponderosa pine

Creator:: Filip, Gregory M.
Abstract:: Root rot caused by Armillariella mellea creates roughly circular disease centers of infected dead and dying trees in the younggrowth ponderosa pine forest under study. Research objectives concerning chemical control of the disease were: 1) to test the effectiveness of certain chemicals in protecting living pines adjacent to disease centers...

Epidemiological insights into Armillaria mellea root rot in a managed Ponderosa pine forest

Creator:: Shaw, Charles G. (Charles Gardner) 1948-
Abstract:: Root rot of ponderosa pine caused by Armillaria mellea was studied in a pine forest that had been under management for 30 years in Klickitat County, Washington. Information sources included disease survey, detailed observation and description of specific disease situations, and examination of roots in situ and removed. Roughly circular...

Growth and sporulation of Phytophthora lateralis in vitro as influenced by the chemical and physical environment

Creator:: Englander, Larry
Abstract:: Phytophthora lateralis Tucker and Milbrath, causal agent of a serious fungus root rot of Chamaecyparis lawsoniana, has seriously damaged natural stands in southwestern Oregon forests and affected ornamentals throughout the Pacific Northwest. Progress with an effective control program in the field has been limited by lack of critical knowledge of...

Infection of stressed ponderosa pines by Armillariella mellea from indigenous and artificial inoculum sources

Creator:: Fuller, Lloyd Randolph
Abstract:: Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically in hazel stems (Corylus cornuta var. californica) which were used in the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.) which had been "stressed" in five different manners plus two control groups. All trees were inoculated twice giving a...

The relation of cover to the distribution of Armillaria mellea in a Ponderosa pine forest

Creator:: Adams, David Howard
Abstract:: Numerous isolates of Armillaria mellea were obtained within a 250 by 450 foot Study Area in a ponderosa pine plantation in central Oregon. These isolates were recovered from roots of armillaria-killed young-growth pine, from large stumps of the former pine overstory, including roots away from the stump proper, and from...

Survival of Phytophthora lateralis in an organic matter fraction of the soil

Creator:: Ostrofsky, William Dow
Abstract:: Chamaecyparis lawsoniana, an extremely valuable timber tree species, is highly susceptible to a serious, soil -borne root disease caused by Phytophthora lateralis. Disease outbreaks of epidemic proportions are continually causing high mortality in natural stands of the host tree. Practical control measures rely on an understanding of the many factors...
