Data were collected by means of a structured questionnaire
administered via personal interviews. This method was used
because some of the respondents did not haveformal education
and many of those who had some education might not be
familiar with the terminology used in the questionnaire. The
questionnaire contained both fix-response and open-ended
questions about common practices of farmers on disposal of
pesticide waste after use. In particular, farmers were presented
with a number of multiple choice tests and were asked to
choose the answer which they thought it best described their
attitude for each particular case. Besides closed questions, free
spacefor alternative answers was also included in all questions.
