Abstract

DETERMINATION of residues has become an important aspect of herbicidal research. Efforts are continually being made to increase the sensitivity of known tests for the chemical analysis of a large number of herbicides. Aquatic herbicides must be effective and used in small quantities (usually 1.0–5.0 p.p.m.) to be economically feasible; consequently, their residues are usually very small.
