The results of an international termite exposure test have indicated that pine sapwood stakes 2 by 4 by 18 inches furnish an effective means for testing the protection provided against decay and termite attack by various wood preservatives. The Forest Products Laboratory during late 1938, in cooperation with others, treated test stakes of southern pine sapwood with several preservatives for installation at the Harrison Experimental Forest at Saucier, Miss. Replicate sets were treated for installations at Madison, Wis., Bogalusa, La. Jacksonville, Fla., and the Canal Zone, Panama. Since 1938, additional preservatives have been added to these tests, principally at the Saucier, Miss., station. Stake tests are useful for screening out ineffective materials. They can be used to advantage as a means of further exploring the preservative properties of materials that show promise in a laboratory toxicity tests. The limitations of these somewhat accelerated field tests must be recognized, however, by those who wish to make use of them.
