Abstract:

The generally high tolerance of acid-forming brown-rot fungi and the low tolerance of whiterot fungi to copper sulfate was confirmed for 16 species, including Poria cocos Wolf., a fungus associated with the failure of copper-napthenate treated fence posts in Florida, and four other brown-rot species not previously reported as copper tolerant. The tolerance of the brown-rot species was strikingly increased by lowering the pH of the substratum from pH 6 to pH 2 with sulfuric acid. Several mechanisms for fungus tolerance to copper have been suggested all require a decrease in the pH of the medium. Author
