One observation this year. Following last autumn we only got two fields of wheat planted the rest bar W Linseed went in to canary seed or SB, SO.
This autumn I drilled some oats straight from the combine into the wheat stubble. Of this I lost 75% to slugs, wasn't too worried as it was only got a bit of cover. Wheat was planted early September on the linseed and canary stubbles and not a slug to be seen really. The barley stubble had greened up and no sign of slugs there either. Seems that for some reason wheat had become a slug magnet here.
Having just spent a couple of days drilling oats into wheat stubble on heavy soil with quite a lot of residue I am quite worried. Put the call out to the pellet man, just hope he can get there soon.
