METHOD OF PREVENTING PINE WILT DUE TO NEMATODE AND APPARATUS FOR PREVENTING PINE WILT

摘要

In order to effectively and efficiently prevent pine wilt by electrical shock regardless of the number of standing trees, voltage pulses are applied to all or several branches extending from the middle to the top of a pine trunk and thus electrical pulses are passed toward the earth through the branches and the trunk. Thus, the growth of pine wood nematode parasitic on the above branches is inhibited to thereby prevent pine wilt.
