Some problems in chemical control of forest pests
Spraying Toxaphen against mice in forest cultures seems to be doubtful on the strength of side effects. The effectiveness of toxic baits for mice control should be increased by raising attractiveness as well as by reducing the size of baits. Experiments showed that Tetrachlorvinfos can be used forHylobius-control in place of DDT. Within young coniferous stands cleared by chemicals bark beetles can be controlled by felled stems sprayed with BHC. For avio chemic measures against larvae in the crowns of conifer the best results were obtained by using insecticides mixed with Diesel oil.
