Extract

The search for means of controlling submersed aquatic weeds has emphasized the need for evaluation techniques that can be used for the discovery and development of effective herbicides. Before the development and use of aromatic solvents, submersed aquatic weeds were usually removed mechanically. Mechanical removal is time consuming and costly and contributes little toward lasting control or eradication of the weeds. Recently, a number of herbicides that provide some degree of control have been developed. Many of these materials, however, are toxic to irrigated crops and to fish and other wildlife, and the control period is short. The evaluation techniques reported here were designed for use in the discovery and development of new and more efficient herbicides.
