  • Among 54,251 licensed pesticide applicators, 82.8% of whom used glyphosate, it was not associated with any solid tumour or lymphoid malignancy, including non-Hodgkin lymphoma; a possible raised risk of acute myeloid leukaemia in the most-exposed group needs confirmation.

What this means for you

The chemical-hazard rating is what drives the score down. Glyphosate residues are widely detected and its hazard classification is debated by regulators. For home use, non-chemical weed control removes the exposure and the drift onto edible plants.
