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...

Phylloplane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L.), hop (Humulus lupulus L.), mint (Mentha piperita L.) and tomato (Lycopersicon esculentum Mill.)

Creator:: Sontirat, Pattana
Abstract:: Phyllopane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L. ), hop (Humulus lupulus L. 'Fuggle-H'), mint (Mentha piperita L. 'Mitcham') and tomato (Lycopersicon esculentum Mill. ) has been observed by cultural methods. A leaf impression method was used to examine both actively growing and inactive propagules present on...

Influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers.

Creator:: Carre, Deborah Danielle
Abstract:: The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...

Inactivation of Verticillium dahliae in peppermint stems by propane gas flaming

Creator:: McIntyre, John Lee
Abstract:: The fungus Verticillium dahliae Kleb. causes a wilt disease of peppermint, Mentha pipertita L. Propane flaming of peppermint stubble is widely used to control Verticillium wilt in the Willamette Valley of Oregon, but little is known about the temperature required for effective control of the fungus. The purposes of this...

Effects of dry heat treatment of styroblock containers on colonization by selected fungi

Creator:: James, Robert L., Trent, Andy, and United States. Forest Service. Northern Region
Abstract:: Tests were conducted to evaluate efficacy of dry heat (82.2°C for 10, 20, and 60 minutes) to reduce colonization by selected fungi within styroblock containers and residual seedling roots left in containers after seedling extraction. Dry heat alone was generally ineffective in significantly reducing fungal colonization. However, simply wetting container...

Fungal root pathogen interactions in a mixed conifer forest in the Blue Mountains of northeastern Oregon

Creator:: Ferguson, Brennan Angus
Abstract:: The coniferous forests of the Pacific Northwest are affected by a variety of endemic fungal root pathogens. Forest disease surveys have noted the presence of two or more of these root pathogens infecting the same stump or root, and it has been suggested that these fungi may be interacting synergistically....
