Occurrence of Potato Powdery Scab Caused by Spongospora subterranea f. sp. subterranea in Costa Rica

open access: yesPlant Disease, 2002
Powdery scab of potatoes, caused by Spongospora subterranea (Wallr.) Lagerheim f. sp. subterranea Tomlinson, is important worldwide due to its effect on tuber quality and transmission of Potato mop-top virus. Although powdery scab-like lesions have been observed on potato in Costa Rica (1), the presence of the pathogen has not been confirmed. During a
