Azide as NaN3 or KN3 impregnated on clay granules gave excellent control of yellow nutsedge (Cypetus esculentus L.) compared to methyl isothiocyanate combined with chlorinated C3 hydrocarbons (Vorlex) or a non-hand weeded control. Nematode control was obtained with all treatments. Significant yield responses from the use of azide were obtained with all crops.
