Abstract

Three concentrations each of fenvalerate and acephate were tested for efficacy against the spruce bud midge on black and while spruce in southcentral Alaska in 1985. Only the highest concentration of fenvalerate (0.025 percent), which is currently registered with the United States Environmental Protection Agency for forest use, provided significant protection.
