A winter-spring potato (Solanum tuberosum) crop of 379 200 MT valued at nearly 100 million $U.S. is produced annually on 17 600 ha in Florida. The most important production regions are southeastern and northeastern Florida. There are important differences between these two regions in the soil types, pests, and pathogens present, cultivars planted, cultural methods used, and markets targeted. Meloidogyne incognita is the most important pathogen in southeastern Florida and is a problem in northeastern Florida as well. Other important nematodes and soil-borne diseases in northeastern Florida include Belonolaimus longicaudatus, corky ringspot (caused by trichodorid nematode-transmitted tobacco rattle virus), and bacterial wilt (caused by Pseudomonas solanacearum). Management strategies differ depending upon the pathogens, nematodes, and insects present, market destination of the crop (i.e., fresh or processed potatoes), and soil conditions. Management options include use of summer cover
