DOTHISTROMA PINE NEEDLE BLIGHT
Dothistroma (septosporum) (= D. pini) is a needle blight that affects the health and growth of pine trees. Each summer, affected forests around New Zealand are aerially sprayed with a copper fungicide to control the disease.

The Committee’s services are available to all forest owners - large or small, to ensure the best control of the disease in the most cost effective manner.
The DCC purchases bulk supplies of copper fungicide at competitive rates on the world market, purchases spray oil and contracts aerial application of the spray.
The Committee, which is non-profit making, is also responsible for monitoring the programme and reviewing new research and developments that might improve the programme. The DCC members are from major forest growers, Farm Forestry Association and Scion.
In order to ensure that the most competitive flying rates are received, the Committee requires requests for spraying to be made by mid-August of each year.
If
assistance is required to assess levels of infection, you should
contact one of the NZ Forest Owners’Association approved Forest Health
Surveyors, a Registered Forestry Consultant, or someone trained in Dothistroma assessment.Forest owners are urged to act promptly so that their forest can be scheduled on the work programme for this season. For enquiries or assistance with spray programmes contact:
