Magarey, T. Wicks, M. Wachtel] Phosphonic (phosphorous) acid (Foli-R-Fos 200) has been extensively evaluated in glasshouse and field trials since 1986. This new fungicide (at 600 mL/100L) demonstrated a high level of efficacy in the post- but not pre-infection control of Plasmopara viticola. Control equivalent to Ridomil MZ 720WP was achieved up to 17 days post-infection reducing sporulation and hastening oilspot necrosis. A tank-mix with copper oxychloride offers potential to complement existing fungicides in Australian anti-resistance management strategies. Australasian Plant Pathology Society, 1990 Magarey P.
