The response pattern from owners and workers on FA and non-FA
farmswas similar when they were asked to rate the use of pesticides between
1 (always bad) and 10 (always good). The mean rank increased
from 62.4 for FA farm owners, to 88.08 for non-FA farm owners, to
107.39 for FA farm workers, to 167.57 for non-FA farm workers
(Supplementary Table 5) indicating an increasing commitment to
pesticides, with a higher mean rank reflecting a higher proportion of
responses towards the ‘always good’ end of the Likert scale. The mean
rank for non-FA farm workers was significantly different to those for
the other groups (H (tie-corrected) = 88.53, P b 0.001) and the mean
rank for FA farm owners was significantly different to that from FA
farm workers (Supplemental Table 5) suggesting more frequent
responses towards the ‘always bad’ end of the scale amongst owners
compared to workers. The difference in mean rank between FA farm
owners and non-FA farm owners was not significant.
