摘要：
C-butachlor andC-oxadiazon could be released from four kinds of CR formulations into water respectively, and the release percentage of each herbicide increased with time, which could be expressed by regression equations （very obvious positive relationship）. The release percentages ofC-herbicides from CR formulations were related to herbicide CR formulation and water type. Total recovery includingC-released andC-left in formulations for eachC-herbicide was high at the 56th day after treatment. Some of the releasedC-butachlor in water could be hydrolysed although under dark condition. The rate of hydrolysis was influenced by water type and formulations.
