Concerns about Scots Pine

Diplodia tip blight causes stunted, brown shoots with short needles. Small black fungal fruiting bodies usually can be seen at the base of infected needles. The disease causes annual destruction of buds and shoots. Red band needle blight produce similar symptoms. The disease usually begins on lower branches and spreads upward causing yellow red spots or bands on needles. Insect pests include the tip moth, sawfly, aphids, and the pine needle scale.

Management Practices for Scots Pine

Control of diseases requires the use of protectant fungicides when the new growth is emerging in May. It is also important to promote good air circulation by adequate tree spacing and weed control. Improve tree vigour through mulching, fertilisation and watering. Control of insect pests requires 3 to 4 sprays of an insecticide at 3 week intervals from May onwards.
