Applications Natural Select TM pressure-treated wood is effective against termites and fungal decay, both above ground and in ground. Wood treated with the two preservatives performs in a very similar manner. The formulations of the preservatives are different, however. CCA consists of copper, chromium, and arsenate. Treating procedures and retention levels are nearly identical.
Copper is the principal active ingredient, protecting against termites and fungal decay.
Protection against copper-tolerant fungi is provided by an organic azole also used in fungicides applied to fruits, peanuts, and other crops. The formulation renders wood useless as a food source for termites and fungi while keeping the wood attractive, clean, and odorless. As a result, fewer environmental restrictions apply. No special EPA precautions apply to handling the wood. All Rights Reserved.
