Avocado, a significant fruit crop grown in many tropical and subtropical parts of the world, is threatened by Phytophthora root rot (PRR), a disease that has already eliminated commercial avocado production in many areas in Latin America and crippled production in Australia and South Africa.  Just in California the disease is estimated to cost avocado growers approximately $30-40 million a year in production losses.
