I am an organic gardener can I use this method without fearing the chemicals? Fungicides registered for the control of peach leaf curl include liquid lime-sulfur, chlorothalonil (Daconil, Bravo 720), ferbam, and copper-based fungicides (numerous trade names are available) including Bordeaux mixture. Follow all label instructions regarding amounts of pesticide to use, method of application, and safety warnings.

Is this really the only way to go and if so is it SAFE?
