Abstract
Pesticide use is a core strategy to control agricultural pests. Although international treaties and health recommendations call for banning hazardous pesticides, globally harmonized pesticide governance remains elusive. In Latin America (LATAM), the main net food exporter worldwide, agricultural pesticide use has increased by approximately 500% since 1990, compared with only approximately 3% in Europe. To assess the environmental and health rigour of LATAM’s pesticide legislation, we reviewed active ingredients (AIs) approved for ten major crops, and AIs banned at national level, in eight LATAM countries, assessed their hazardousness according to international standards, and legal status in the European Union (EU) and explored sources of variation in the number of AIs approved in LATAM. We identified 523 AIs approved and 236 banned in LATAM; approximately 50% of the approved and approximately 85% of the banned AIs in LATAM were either not approved or prohibited in the EU. Higher crop production and, to a lesser extent, export value were linked to more AIs approved in LATAM. These findings imply weaker regulatory frameworks for hazardous pesticides in LATAM, reflecting more permissive environmental policies compared with the EU. This reinforces the urgency of addressing asymmetries in pesticide governance and rethinking the prevailing agricultural paradigm.
