Red House Farm: Leaf damage to oilseed rape seedlings starts off relatively high



Early October saw the first of the oilseed rape crop appear on the trial plots at Red House Farm. With high rainfall over the summer we knew that slug pressure on the crop would be fierce and wanted to make sure that we kept a close eye on the crop as it developed. 

The first sampling event revealed what we expected, with relatively high levels of leaf damage on the seedling crop straight away.  The first sampling event revealed average % leaf damage was 19% on the metaldehyde applied areas of the crop and up to an average of 29% on the SLUXX applied areas.  This was not an encouraging start.
