Abstract

Spray operations against the spruce budworm have been conducted in New Brunswick in 1980, 1982 and 1983 and in Nova Scotia from 1980 to 1983. The results obtained in terms of foliage protection have been extremely variable. Attempts to pinpoint the causes for this variable result suggest that a number of factors are responsible. These are weather during and after spraying and sampling problems.
