Previous studies have shown that seed dressing with methiocarb or metaldehyde can protect newly emerged oilseed rape seedlings from slug damage. Here, we document two mini-plot field experiments testing these seed dressings. Both metaldehyde and methiocarb significantly reduced slug damage compared with untreated control seeds, but both seed dressings performed less well to the metaidehyde bait pellets. Protection offered by metaldehyde seed dressing was short-lived, whereas methiocarb seed dressings gave protection throughout the 4 weeks duration of both experiments. (c) 2005 Elsevier Ltd.
