Other claims from this paper (7)
- Intervention effect Seedling growth and biomass of the target weed decreased proportionally with extract concentration.
- Intervention effect Chlorophyll content and protein levels of the target weed decreased proportionally with extract concentration.
- Observation Complete plant mortality of the weed occurred at the highest extract concentration.
- Observation GC-MS analysis of Argemone mexicana extract identified 23 bioactive compounds, primarily alkaloids (protopine, sanguinarine, berberine) and phenolic acids (caffeic and ferulic acid).
- Intervention effect In field trials the extract at 200 mg/mL gave 96.5 % weed control efficacy within 7 days, comparable to synthetic herbicides.
- Mechanism The authors attribute the herbicidal activity of A. mexicana extracts to multi-compound synergistic effects.
- Recommendation The authors conclude that practical application of the extract needs work on concentration requirements, cost-effectiveness and broader spectrum validation.
