: All study materials were approved by the Higher Degrees, Research and Ethics Committee (HDREC) of Makerere University in Uganda (HDREC 718). The Ethical Board of the Ethikkommission Nordwest- und Zentralschweiz in Switzerland (EKNZ-REQ-2019-00850) declared this research does not need approval.Agro-input dealers, and where applicable their customers, consented to participate in the research for the KAP interview, the sale observation and the shop observation. Due to the nature of the method applied, agro-input dealers could not consent to the mystery shopping. When agro-input dealers were approached after the mystery shopping and did not consent to the KAP interview, or if they were not available for a KAP interview, we did not evaluate the data obtained during the mystery shopping. Farmers who pretended to be customers during the mystery shopping were thoroughly briefed and consented to their covert action before implementation.
