BACKGROUND Sudden death syndrome (SDS) caused by the ascomycete fungus, Fusarium virguliforme, exhibits root necrosis and leaf scorch or foliar SDS. The pathogen has never been identified from the above ground diseased foliar tissues. Foliar SDS is believed to be caused by host selective toxins, including FvTox1, secreted by the fungus. This study investigated if the xylem sap of F. virguliform...

Inheritance of resistance to Stemphylium solani and to its phytotoxin in cotton cultivars Leaf blight of cotton (Gossypium hirsutum) caused by Stemphylium solani occurs in several cotton growing areas of Brazil, and causes severe yield losses especially in the State of Paraná. The inheritance of resistance to S. solani and to its phytotoxin was investigated in three cotton cultivars. Crosses in...

Garlic leaf blight caused by Stemphylium solani is a serious disease in vegetable-growing areas of China (28). Symptoms of the disease start as small white spots (1 to 3 mm) enlarging to elongated purple necrotic lesions along the vein, followed by blighting of the leaf tips. Similar symptoms were produced by culture filtrates of S. solani, and a strong correlation was also found between garlic...
