Abstract
Fumigation with methyl bromide in Sept.-Oct. or Feb.-March had no significant phytotoxic effect on 2+0 naked rooted seedlings or 1+0 container stock of Pinus contorta. Larvae of Rhyacionia buoliana were equally susceptible (99% mortality) to fumigation in spring or autumn; mortality of R. buoliana was 100% in dry conditions.
