Exclusion criteria

Previous Version

Pesticide shops located 10 km or more from the study area boundary will be excluded from the study because this distance is outside of the usual travelling distance for pesticide purchases, as noted in the Vendor pilot study.

Next Version

Pesticide shops located outside from the study area boundary will be excluded from the study because review of out-of-study area purchases, after six months of data collection, revealed that cross-boundary purchases were minimal. Such external zone was not required while adding substantial work to the study.
