Abstract
Residual toxicity of prometryne and fluometuron was assayed in six different soils after three months of herbicidal treatment . the persistence of herbcides varied in different soils, fluometuron was more persistent than prometryne .
residual toxicity of prometryne was completely lost in heavy soil. In general, residual toxicity of the herbicides was inversely related to the amount of colloidal material in soil. Degradation of herbicides was also associated with soil pH. Formulate for the estimation of
