Distribution of study participants (own illustration, adapted from CONSORT flowchart [24]).

AD: agro-input dealer; DAO: district agricultural officer. Reading explanation: Of the 479 agro-input dealers approached, 25 Shops were closed and 50 agro-input dealers refused to take part in the study, resulting in 404 KAP interviews (310 + 94) that were started. 402 of the interviews were finished and used for analysis. From 107 MYS conducted, ten MYS had to be excluded from analysis because the agro-input dealers refused to take part in the KAP survey. Additionally, three MYS could not be included in the analysis because the KAP survey was conducted with a different staff member than the MYS. 10 agro-input dealers refused the shop observation, thus 392 shop observations were conducted. At 236 shops a sale observation took place because 156 agro-input dealers did not have any customers during the time the researchers were at their store or they did not give consent. In one case, only a sale observation but no shop observation was conducted
