Theses and Dissertations
Phytophthora erythroseptica Pethyb. is a devastating fungal pathogen of potato (Solanum tuberosum). The pathogen causes a disease known as pink rot. Pink rot results in necrosis and decay of tubers; and is responsible for major losses pre and post harvest. Attributes of the disease are progressing toward epidemic proportions. To help prevent such dramatic outbreaks of the disease, understanding the factors associated with incidence will provide opportunities to control the pathogen. A link between pH and disease severity has been observed. We studied the effects of pH and Ca to determine their influence on disease development. Low pH and Ca …
