Abstract:		"White rot is an economically significant disease of Allium crops. The pathogen Sclerotium cepivorum produces long-lived sclerotia that germinate in response to sulfur-containing compounds released from Allium roots. Diallyl disulfide (DADS) was the primary organic sulfur compound detected in the rhizosphere soil of two garlic cultivars, 'California Early and Late', growing in greenhouse conditions. DADS, dimethyl trisulfide (DMTS), dimethyl disulfide (DMDS), isopropyl disulfide (IPDS), dipropyl disulfide (DPDS), diethyl disulfide (DEDS), together with garlic oil, garlic juice, garlic powder, raw onion pieces, cabbage pieces, and Chinese cabbage pieces were investigated for their activities toward germinating dormant sclerotia. Results showed that DADS and other volatile sulfur compounds could stimulate sclerotial germination, and a dose-response was observed. In addition, garlic juice, powder, raw onion, and the two cabbages could stimulate sclerotial germination. Furthermore, the laboratory soil incubation experiments demonstrated the strong interaction of organic sulfur compounds with soil"
