Survey of environment harmonizing type control techniques against forest disease
1998 - 2000
Investigating Researcher (2)：
In order to study the control methods against forest diseases confronting in many regions, which are not by chemical spray, but are considered to the virus ecology and tender to environment, the survey of Matsuzai-Senchu-byo (disease by pine wood nematode) and Roshi-byo (resinosis disease) of Japanese cypress is carried out. As to Matsuzai-Senchu-byo, clarifying the causes of the over-the-year dead trees and latent infected trees on damage propagation, the proof test forests to control methods by the surface ground plowings and the mixed plantings are set up. And as to Roshi-byo, clarifying the ecology of disease virus, the proof test forests are also set up and the same surveys are carried out.
