Abstract

A comparison of the fungicidal value of mercuric chloride solutions made up in tap water with those made up in distilled water showed that the tap water solutions were much less effective in killing the sclerotia of Rhizoctonia solani on potato tubers. Of the 182 sclerotia treated with bichloride, 1-1000 in distilled water, only 6 or 1.1 per cent grew. In the case of a similar treatment of tap water solution of the 139 sclerotia examined, 34 or 7.1 per cent grew. Ninety per cent of untreated sclerotia grew in the control experiments. These facts are important in the application of seed treatments where the grower uses hard water in making up disinfecting solutions.
