Pest or Disease on Scots & Black Pine
I have noticed a fair bit of pine drop more noticeable on the Scots Pine. Both species are leaking white resin mainly at the tips. I cant find any Adelgids or Conifer aphids (maybe they have been and gone?) so am not sure as to why this is happening. The trees are irrigated and not under any particular stress.

This would be Diplodia Tip Blight. This is common in these, among other coniferous trees. Have you noticed any actively bleeding cankers elsewhere on the trees?
