The September 1999 issue of Crop Protection reported about scientist Wagner Bettiol’s study on using diluted milk as a control for powdery mildew on cucurbits. Backed by Embrapa, the Brazilian Agricultural Research Corporation, the study reported that a solution of 10% – 20% raw milk in water sprayed weekly was equally effective or better than the most trusted chemical fungicides on the market (around 90% effective, depending on the plant variety’s natural disease resistance). Continued studies at the University of Adelaide in Australia seek to understand why milk works so well against powdery mildew (and also botrytis blight, which you may have seen on your squash flowers or strawberries — it’s that fuzzy mold that appears in wet conditions).

Milk which is not raw, won't work... The pasteurization processs kills off all of the bacteria.
