1. Both Pseudoperonospora Humuli and Phytophihora infestans are extremely susceptible in the zoospore stage to the action of weak solutions of soap or saponin. The zoospores are caused to disintegrate suddenly, apparently by changes in surface tension, within 60 seconds, in solutions containing over 0·1 per cent, soft soap. Those of P. Humuli are more vulnerable than those of P. infestans.2. The fungicidal action of soap and saponin mixed with certain adherent substances was tested on hop plants.3. The power of adhesion and the fungicidal efficiency of the mixtures were tested by allowing single drops to dry on the surface of watch glasses and by then adding drops of water containing zoospores.4. Other substances, e.g. aluminium-lime mixture, glycerine, iodine, bromine, were also found to kill zoospores rapidly.

1. It is suggested that the fungicidal action of sulphur upon the Erysiphaceae is due primarily to hydrolysis.2. The presence of alkali, which brings about an acceleration of this hydrolysis, should enhance the fungicidal properties of sulphur.3. An explanation is thus afforded of the inhibition of the fungicidal action of sulphur against the hop powdery mildew (Sphaerotheca humuli) by gelatine or saponin solutions when employed as the spreader and of the promotion of fungicidal action in the presence of soft soap and alkali casein solutions.4. Attention is drawn to analogies between the action of sulphur upon the mildew and upon copper.5. Current views relative to the fungicidal action of sulphur are discussed from the standpoint of the hydrolysis hypothesis.

Logarithmic Reduction

OBJECTIVE: this study aimed to evaluate the efficacy of hand hygiene performed with two different soap formulations: 0.3% Melaleuca alternifolia essential oil versus 0.5% triclosan, and to compare them with two reference hygiene procedures: the official methodology procedure (soft soap) versus the draft version of the procedure (soft soap + propan-2-ol). METHOD: using the European EN 1499 method, logarithmic reduction factors were determined for the number of colony forming units of Escherichia coli K12 before and after hand hygiene of 15 volunteer subjects, and compared using the one-tailed Wilcoxon test. RESULTS: referring to the soft soap, there was no difference between the performance of soap with 0.3% M. alternifolia and soap containing 0.5% triclosan. The soft soap + propan-2-ol proved to be more effective than the other hand hygiene procedures. CONCLUSION: studies to verify the therapeutic efficacy of essential oil in hand hygiene can improve adherence to this practice.
