Response of Onions Grown for Transplants to Soil Fumigation1

Year: 1978

Type: article

Abstract: Six general-purpose fumigants applied by different methods were evaluated for control of the fungal-nematode complex on onion ( Allium cepa L.) for transplant production. Most soil treatments improved plant vigor, size, uniformity, and yield, and these positive responses were correlated with reduced populations of soil-borne fungi and nematodes. Growth response and control of pathogens varied with the fumigant used and the method of application. Populations of Pythium spp. and Fusarium spp. were reduced with methyl bromide, methyl bromide-chloropicrin mixture, chloropicrin, DD-MENCS (Vorlex), metham (748 liters/ha, drenched) and Bunema (drenched). Metham (748 liters/ha, drenched or drenched and incorporated) controlled Rhizoctonia solani Kuehn. Complete control of root-knot nematodes was obtained with methyl bromide and methyl bromide-chloropicrin mixture and nearly complete control with chloropicrin and DD-MENCS.
