Experimental Work with the Introduction of Chemicals into the Sap Stream of Trees for the Control of Insects
The introduction of chemicals into the sapstream of living plants for the control of insects and diseases and also for the preservation of the wood has been the object of experimentation for more than 100 years. It has been found that this principle is thoroughly sound within certain limitations. It is likewise practical for purposes to which it can be adapted, such as the treating of small timbers in the round and for the control of bark beetles. Two papers follow, one by F. C. Craighead and R. A. St. George and another by W. D. Bedard. The former paper discusses the more general aspects of the problem of introducing chemicals into trees while the latter describes the application of the method for the control of the mountain pine beetle.
