Citrus Canker: The Pathogen and Its Impact

Increasing international travel and trade have rendered U.S. borders more porous and dramatically increased the risk of introductions of invasive plant pests into agricultural crops (3). The current USDA system for protecting agricultural industries has been overwhelmed and has sometimes failed to intercept a number of introductions of exotic pests, including plant pathogens. Such introductions threaten crops and can hinder national and international agricultural markets and trade. Currently in Florida, one such invasive species is
