Implication

Agronomic field trial demonstrates stable crop yields despite weed community shifts in herbicide-tolerant maize, suggesting glyphosate supports flexible integrated weed management.

Key Points

To evaluate the agronomic and ecological effects of incorporating glyphosate into various weed management programs in herbicide-tolerant maize.
Conducted a farm-scale agronomic field investigation over three consecutive cropping seasons (2012–2014) in central Spain.
Evaluated five weed management programs: standard pre- and post-emergent herbicides, a reduced-dose conventional program, and three glyphosate-based programs using one or two post-emergent sprays alone or combined with pre- or post-emergent options.
Weed density across each cropping season was higher in management programs omitting pre-emergence herbicide applications than in programs incorporating them.
None of the evaluated weed control programs reduced maize grain yields or decreased weed species richness and diversity, although weed community composition varied significantly among programs.
