Glyphosate is one of the most widely used active substances in pesticides to prevent unwanted plant growth around planted crops or to kill plants or parts of plants. These substances are often called ‘herbicides' or ‘weedkillers'.

Glyphosate is used in agriculture and horticulture to combat weeds before sowing. Where genetically modified plants with resistance to glyphosate are grown, the substance is also used after sowing to kill weeds growing amongst the crops. This practice does not, however, happen within the European Union.

ECHA manages the law on the classification and labelling of substances and mixtures. This law regulates the way in which substances are assessed and labelled, based on the hazardous properties they may have – for example poisons, flammable substances, corrosive substances and so on.

For certain substances, such as active substances in pesticide products, a decision on the classification may be made at EU level to apply across the whole of Europe. In practice, this means that the relevant labelling will be required to warn consumers on every product containing the substance.
