Population Structure of Pythium irregulare, P. ultimum, and P. sylvaticum in Forest Nursery Soils of Oregon and Washington.

Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these concerns, a total of 115 isolates of three Pythium species (P....

Damping-off of Sweetgnm by Pythium sylvaticum

During the spring of 1964, preand postemergence damping-off killed many sweetgum (Liquidambar styraciftua L.) seedlings in a nursery at Stoneville, Miss. Fusarium solani (Mart.) Appel & Wr., Sclerotium rolfsii Sacc., Talaromyces spiculisporum Benjamin, and Pythium sylvaticum Campbell & F.F.Hendrix were isolated from the diseased seedlings. At soil temperatures similar to those prevailing when d...

Sensitivity of North American Isolates of Phytophthora erythroseptica and Pythium ultimum to Mefenoxam (Metalaxyl)

Since their introduction in the late 1970s, phenylamide fungicides have been used effectively to control diseases caused by the Peronosporales. These fungicides have a very specific mode of action; inhibiting fungal ribosomal RNA polymerases (7). Because of this specificity, there is a relatively high risk that resistance to the fungicide may appear quickly in the target fungal population (3). ...

Seed-colonizing microbes from municipal biosolids compost suppress Pythium ultimum damping-off on different plant species.

Composts are known for their suppressive properties toward many different seed- and root-infecting pathogens and diseases. Although disease and pathogen suppression induced by composts is believed to be mediated by microbial activities, the nature of the microbial species and processes responsible for suppressiveness remain unknown. We demonstrated previously that seed-colonizing microbial cons...
