Two applications of the protectant fungicides, Bravo, Manzate 200 and DPX 164 reduced foliar infection of turnip rape (Brassica campestris) by Albugo Candida. However, the fungicides had no apparent effect on staghead formation, the systemic phase of the disease. The acylalanine fungicides CGA 29212 and CGA 48988 showed excellent eradicant activity against foliar infection in growth room tests. In a field test, CGA 29212 significantly reduced the number of stagheads. CGA 38140 showed no activity against A. Candida on turnip rape.
