We assess decision making when growers choose to invest in a new fruit cultivar, given the tradeoffs between superior fruit quality and improved disease resistance. We also estimate the welfare effects of adopting a cultivar with improved disease resistance. Florida strawberry growers are more willing to pay for fruit quality relative to improved disease resistance. When adopting a cultivar with improved disease resistance, Florida strawberry growers save between $182.40 and $204.50 per 1,000 plants every annual harvest period. Our findings improve the understanding of how strategic decisions are made to meet increasing marketplace demands for superior fruit quality and reduced chemical applications.

We investigate how phytosanitary regulations related to apple maggot could affect optimal pest control strategies and profits for apple producers potentially located in apple maggot quarantine areas. We estimate producer profits by an orchard's quarantine status subject to a phytosanitary regulation requiring an additional cold storage period, reflecting the import requirements of China and British Columbia (Canada). Interestingly, we find that the increased cost burden generated by the additional cold storage from quarantine areas has an unintended consequence of raising the number of chemical applications, suggesting a substitution effect between pesticide application and cold storage.
