Financial and health costs of pesticide use in growing conventional and genetically modified potatoes in Prince Edward Island

This study focuses on economic analysis of the use of conventional and genetically modified potatoes in Prince Edward Island in the context of health risks of air-borne pesticide residues and consequent potential impacts on the health of farmers and their families. Estimates of health impacts and other related costs are developed for conventional potato growing practices and in growing genetically engineered potatoes (NewLeaf, NewLeaf Plus and NewLeaf Pro potatoes, each genetically modified for particular traits). From interviews with potato specialists and potato farmers, it was discerned that pesticide applications were reduced when using the genetically modified potatoes. The extent of reduction in pesticide applications is documented and translated into financial benefits and potential health benefits received by the pesticide applicator. It is concluded that the financial benefits gained from the use of fewer inputs are much more substantial than are the health costs associated with the exposure to pesticides.
