Environmental considerations of disinfectants used in agriculture.

Using disinfectants in agriculture increasingly requires consideration of the indirect effects on the environment and human health. At present, only limited information is available on post-application effects of disinfectants, and such data therefore needs to be gathered in order to assess potential effects. In addition, a basis exists for establishing precautionary guidelines using current information. Optimum handling and application procedures require a knowledge of the specific features of each type of disinfectant. A need to establish product standards through efficacy tests has also emerged. The benefits of disinfectants for disease control must also be weighed against any environmental consequences. Emergency application of a disinfectant carries different implications from routine use on farms, and any large-scale application should undergo an environmental impact assessment.
