Abstract
Abstract Ethylene oxide, methyl bromide, mercury and organo‐mercury compounds were ineffective as fumigants for the purpose. Chloropicrin proved more satisfactory, fumigation at saturation concentrations killing the three pathogens, when diseased Zelka seed with a moisture content of 16% was exposed for 72 h. at 20°. This unusually long treatment was necessitated by slowness in penetration. Zelka showed little fumigation damage in the laboratory or in the field. A ‘Blue’ variety showed little damage in field trials, in which the emergence of Feltham Advance was reduced by 29%. All seeds were so heavily infected that some interaction between fungal and fumigation damage was anticipated. A commercial sample of the variety Onward was very susceptible to chloropicrin. In all experiments the vigour of plants grown from fumigated seeds was normal. Cultures of the pathogens were killed by dilute aqueous solutions of chloropicrin, the responses of the three species being markedly different.
