| Abstract/Contents: | Pythium aristosporum and P. arrhenomanes are reported as new pathogens of the secondary roots of Agrostis palustris grown on golf green mixes with a high sand content. P. vanterpoolii also was found associated with the roots but was not pathogenic. The total, shoot, and root dry weights of plants root-inoculated with P. aristosporum and P. arrhenomanes decreased in sand and to a lesser extent in sand-loam media. Both pathogens developed throughout the cortical and vascular tissues of the roots but did not produce lesions or rot. Infected roots occasionally had a light buff coloration. Mycelium was observed in root hairs, and infected root tips were bulbous and ultimately devitalized. Sporangia and oospores were rarely observed in infected roots. |
