Abstract
A cross-sectional study of knowledge and practices related to
use of pesticides among
vegetable and rice growers in Bangladesh
By Alison Clune
Background: Several studies suggest that poor pesticide
application practices contribute
to adverse health effects associated with pesticide
poisoning.
Purpose: To investigate whether better knowledge of safe
pesticide application and
storage is associated with safer application and storage practices
among farmers in
Bangladesh.
Methods: Interviews were conducted with 72 farmers including
kitchen gardeners, local
farmers, and city/regional farmers. A standardized questionnaire
was used to collect
information about farmers' practices, knowledge, and attitudes
about pesticide
application and storage. Practice, knowledge, and attitude scores
were used to
summarize questionnaire data. Multiple linear regression and
mapping were used to
explore the relationship between knowledge and practice of safe
pesticide application and
storage. Informal focus groups were conducted separately to
supplement questionnaire
data.
Results: None of the interviewed farmers had formal training on
pesticide application or
storage, and 89% received pesticide application and storage
information from other
farmers. A marginally significant association was found between
pesticide knowledge
and application and storage practices in the final multiple linear
regression model
(p=0.0863). The level of knowledge about such practices was higher
and less varied in
southwest districts than in central districts, and the relationship
between knowledge and
practice was similarly reflected in the mapping analysis. The
association between
pesticide knowledge and practice was about four times greater when
a farm was located
in a town compared to a village, municipality, or slum. The
strength of association also
increased with the number of pesticide information sources reported
by the farmer.
Conversely, farmers who grew beans exhibited a weaker association
between pesticide
knowledge and practice than those who did not grow beans, likely
because beans require
high pesticide inputs.
Conclusions: Greater pesticide knowledge may lead to safer
application and storage
practices, and the best way to disseminate information about
pesticides is through word-
of-mouth.
Recommendations: Based on these results, it will be possible to
develop community-
based training on pesticide application and storage that encourages
word-of-mouth
knowledge dissemination to mitigate occupational hazards associated
with pesticide
application and storage.
