Yields of Onion Cultivars in Midwestern Organic Soils Infested withFusarium oxysporumf. sp.cepaeandPyrenochaeta terrestris

Pathogenicity and mycotoxin production by Fusarium proliferatum isolated from onion and garlic in Serbia

“…Although in previous reports, wilting of onion plants showing rot of the basal plate of the bulb in the field has been (Lacy et al 1982) and the rot of the basal plate of garlic is most often caused by F. culmorum (Rengwalska and Simon 1986), we rarely isolated F. oxysporum from garlic and onion, while we never isolated F. culmorum from either host plant. The data of the pathogenicity tests that we performed showed that F. proliferatum should be regarded as a potentially serious pathogen of onion and garlic in Serbia.…”

“…Wilting of young and adult plants of onion (Allium cepa) is caused by a complex of species of the genus Fusarium among which F. oxysporum f. sp. cepae is considered the most important onion parasite worldwide, causing rot of the basal plate of the onion bulb (Lacy and Roberts 1982). Rot of the basal plate of garlic (A. sativum) is most often caused by F. culmorum (Rengwalska and Simon 1986) which can be responsible for losses of garlic cloves of up to 40% in the field, and even higher in storage (Schwartz and Mohan 1995).…”

Review on Aggregatum Onion (Allium cepa L. var. aggregatum Don.)

“…Pathogen survives in soil and onion bulb in the form of chlamydospore for many years. Yield losses of 25-35% due to Fusarium basal rot have been reported in onion (Lacy and Roberts, 1982).…”

Onion diseases

“…Both of the above fungi fit the same environmental niche and they have often been present together in a disease complex in onion roots, which made it difficult to decide which of the two was the main cause of damage (Lacy and Roberts, 1982). It is now accepted that the pathogens can act independently to cause disease: P.…”
