An economic analysis of incorporation methods for preplant herbicides on clay loam soil.
In trials on a clay loam soil no significant difference was evident in the control of Amaranthus hybridus and A. retroflexus in cotton when the herbicides were incorporated by discing, cultivating or rotary cultivating. Tribulus terrestris and Echinochloa crus-galli were controlled best where the herbicides were incorporated by rotary cultivation. Cotton lint yields were unaffected by the choice of herbicide or method of incorporation. In general conventional cultivation appeared to be the most effective and economic method of incorporation.
