The World Health Organization classified carbaryl, glyphosate, and paraquat as hazardous to human health. In the Agriculture Health Study in the United States, health problems were associated with the use of these 3 agrochemicals 12 or more times per year. These 3 agrochemicals were commonly used in Grenada. The purpose of this quantitative cross-sectional study was to investigate the relationship between the social and economic characteristics of the farmers who participated in the 2012 agriculture survey and the use of agrochemicals at frequencies that could pose health risks. Five constructs of the social cognitive theory were used as the premise to hypothesize relationships between the variables. Binomial regression analysis was conducted to test the hypotheses of relationships between the characteristics of 8,868 farmers and use of agrochemicals or herbicides -?¥12 timers per year. Statistically significant relationships were found between 16 characteristics of the farmers and use of agrochemicals. Significant relationships were also found between 8 characteristics of the farmers and use of herbicides -?¥12 timers per year. The findings of this study show that several characteristics of the farmers in Grenada were associated with the use of agrochemicals at frequencies that were hazardous to health. By demonstrating the need to implement preventive measures and adopt the precautionary principle in the use of agrochemicals, positive changes can be made in monitoring agriculture practices, health surveillance, and clinical practice.
