Abstract
Two crops of celery were irrigated with: (a) river water, (b) river water irradiated with ultraviolet light, or (c) mains water. Ultra‐violet radiation was effective in reducing the number of coliforms but not pectate‐degrading bacteria in the river water. At harvest, larger numbers of coliforms were found on the celery which had been irrigated with the untreated river water even when the last irrigation had been six days previously. Total colony counts and numbers of fluorescent pseudomonads and pectate‐degrading bacteria on the crop were not affected by the different water sources.This publication has 5 references indexed in Scilit:
