Abstract

Excellent control of the white-pine weevil in young white pine plantations, by applying concentrated lead arsenate spray with knapsack sprayers, was demonstrated and reported several years ago. Since then, research has shown that a number of newer insecticides, used as emulsions, are also very effective.
