Because typically farmers are the main users of pesticides, the degree of awareness about pesticide effects inherently influences their methods of pest management. Perceived pros (beneficial effects) and cons (harmful effects) of pesticides or perceived needs of farmers were main determinants of implementation of alternative methods of pest control in previous studies. For example, farmers who considered that pesticides are harmful to the environment and human health were more concerned by the negative effects and were found to be more reluctant to use pesticides in their pest control practices.
