Abstract

The interaction of soil applied phosphorus and soil applied herbicides was investigated in field, greenhouse and controlled environment chamber studies. A previously reported diuron-phosphorus interaction could not be repeated under all conditions studied. Amitrole was consistently more toxic to plants grown under high phosphorus levels than under low phosphorus conditions. The phytotoxicity of ten other herbicides was not influenced by the phosphorus content of the soil.
