Abstract

Agar-block test was carried out to compare the effectiveness of two laboratory prepared CCA-C wood preservatives against a commercial CCA formulation. Krabak (Anisoptera leavis) wood blocks were used as substrate for Polyporus sanquineus fungi.


Results indicated that weight losses of the blocks treated with three formulations do not differ significantly. Anticipated threshold retentions cannot be determined from this test because of inadequate distribution of retention range.
