- Notes:
- 8 pages., via online journal., The paper introduces the pest belief model and Fishbein and Ajzen's theory of reasoned action to analyze farmers’ decisions in stem borer management. Farmers spent an average of $39/ha (median $18) on insecticides believing that if they had not controlled an average loss of 1004 kg/ha or $402 (median 592, $237) would occur. Farmers’ estimates of the worst attack averaged 19 white heads/m2 (median10) with the associated average loss of 1038 kg/ha or $415 (median 592, $270), implying that farmers’ decisions were guided by the worst attacks. Perceived benefits from insecticides were directly related with farmers’ insecticide use and perceived severity. Perceived susceptibility was also high, with 59% of farmers believing that a loss of 450 kg/ha would be “extremely or very likely”. Farmers believed insecticides could destroy natural enemies but placed only moderate importance to conserving them. Health was believed to be very important but farmers had mixed beliefs that spraying could bring about poor health. This study also provides evidence suggesting high peer pressure on farmers’ spray decisions directly influencing perceived benefits from sprays, insecticide spending and spray frequency.
