Buckeye rot of tomato portion of crop yield in the United States as well as India. The relatively small genome size of "Phytophthora parasitica" compared to "Phytophthora infestans" gives researchers the unique ability to further examine its ability to cause disease. Buckeye rot of tomato affects tomato plants, although there are many other plants that are affected, including pepper, potato, tobacco, pineapple, and various other hosts.
