- Use: Non-selective, systemic herbicide used to kill a wide spectrum of annual and perennial weeds. Crucial in "Roundup Ready" genetically modified crop systems and for pre-planting/pre-harvest weed control.
- Conclusion: Glyphosate revolutionized weed control with its broad-spectrum effectiveness and utility in no-till farming, but intense global controversy surrounds its potential human health impacts (carcinogenicity) and environmental effects (impact on biodiversity, soil health, water quality), leading to regulatory scrutiny, bans in some regions, and increasing pressure for integrated weed management.
