Data from 1997-2003 show that acidified clay products are a valuable alternative to control downy mil-dew of grapevine in conditions of medium rain fall, good spray timing and with a good application tech-nique. The limits of these products show under heavy rain conditions and when there is high disease pressure. date: 2006 date_type: published refereed: never citation: Tamm, Dr Lucius; Amsler, Thomas; Schaerer, Hansjakob; Lévite, Dominique and Häseli, Andreas (2006) Current downy mildew control strategies in Swiss organic vineyards.
