What Readers Want to Know
These are the questions that arrive most often in our inbox. Each answer is short by design; the chapters carry the fuller argument and the sources behind it.
Safety and science
- Is glyphosate the same thing as Roundup?
- Glyphosate is the active ingredient. Roundup is the brand Monsanto launched in 1974; since US patents lapsed in 2000, many generic glyphosate products have appeared under other names.
- Does glyphosate cause cancer?
- IARC classed it as probably carcinogenic in 2015. EFSA, ECHA, JMPR and the US EPA concluded it is unlikely to pose a cancer risk at expected exposures. The disagreement centres on hazard versus risk, and on heavy occupational use. Read the health chapter
- Is there glyphosate in my food?
- Trace residues are often detected, especially in grains such as oats and wheat and in legumes, usually well below regulatory maximum residue limits. Organic certification prohibits its use, though drift can occur.
- Is it harmful to bees and wildlife?
- Direct toxicity to bees is generally low, though some laboratory studies suggest effects on bee gut bacteria. Indirect effects matter more: clearing flowering weeds removes forage, and some formulations are more toxic to aquatic life than glyphosate itself.
Law, farms and gardens
Is glyphosate banned in Europe?
No. The EU renewed approval in November 2023 until 2033. Member states may restrict specific products and uses.
Which countries have banned it?
Sri Lanka banned it in 2015 and partly lifted the ban in 2018; Vietnam announced a ban in 2019; Mexico decreed a phase-out in 2020 that was later postponed.
Why did Bayer settle if regulators say it is safe?
Bayer said its 2020 settlement of roughly $10.9 billion was meant to end litigation uncertainty and did not admit liability. Courts and regulators apply different standards.
Why do farmers still use it?
It is cheap and effective, and it makes no-till farming practical, reducing erosion and fuel use. Read the farm chapter
What can gardeners use instead?
Mulching, hand-weeding, hoeing, dense ground-cover planting and boiling water on paving work well for small areas, at the cost of more time.
