Narrow efficacy ranges and weed resistance limit the utility of single-active herbicide applications. Expanding the control spectrum prevents crop yield loss from surviving competitive vegetation.

Individual herbicides often fail to control a sufficiently broad range of resistant or diverse weed species. Expanding the efficacy range prevents crop yield loss and reduces the need for multiple separate applications.

Existing chemical controls fail to eliminate biotypes that have evolved tolerance or resistance mechanisms. Overcoming this survival ensures effective crop protection and prevents yield loss.

Individual herbicides often fail to control a broad range of weed species or resistant biotypes. Expanding the control spectrum prevents crop yield loss and reduces the survival of noxious weeds.
