Addition of the methylcarbamate compounds p-chlorophenyl
N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate
(carbaryl) to various herbicides has resulted in reduced rates of

in both plants and soils while PPG-124 has only been demonstrated
to affect degradation in soils. Both these materials are effective...
Evaluation of the safety hazards along a highway is usually
