| Abstract: | Abstract During the present century increasing world demand for forest products has brought about a rapid expansion of even-aged forest plantation estates, requiring the forester to adopt the outlook and techniques of the farmer to an increasing extent, both to maintain yield and protect crops from damage. Aircraft have already proved their worth in the protection of natural and artificial forests from fire and are frequently used for seeding, fertiliser application, survey and the control of insect pests. They are also potentially useful for the control of forest diseases, although their role in this respect has so far been limited. The development of aerial spraying to control dothistroma blight of Pinus radiata is reviewed in this paper. |
