Potential interventions for preventing pesticides self-poisoning by restricting access through vendors in Sri Lanka

Background: In South Asia, up to one in five individuals who use pesticides for self-harm purchase them immediately prior to the event. Aims: From reviewing the literature we proposed four interventions: (a) farmer identification cards (ID); (b) prescriptions; (c) cooling-off periods; and (d) training pesticide vendors. We aimed to identify the most promising intervention. Method: The study was conducted in […]
