ASSESSMENT AND CONTROL OF DOTHISTROMA NEEDLE-BLIGHT

摘要

The object of this handbook is to provide a source of reference and an introduction to the routine forestry practice of treating exotic pines against Dothistroma needle-blight. The information provided has been gained from over 30 years of research and experience in operational control of Dothistroma needle-blight. This handbook updates three previous versions, published in 1979,1982, and 1988, and it is hoped that readers will find it a useful reference guide for running a successful Dothistroma control programme. Dothistroma pini is a fungus that causes a needle cast of conifers. It was first noticed in New Zealand in the central North Island in 1962 and positively identified in 1964 (Gilmour 1967a). In our exotic forests the most important tree species which are significantly affected are Pinus radiata, P. nigra subsp. laricio, and P. ponderosa.
