Many vegetable crops, vetch, clover, and certain varieties of soybean are excellent hosts. Nonhost crops include corn, sorghum, peanut, and winter grain crops such as wheat, rye, oats, and barley.
Many weeds are also good hosts for reniform nematode.
Some of the better weed hosts are cocklebur, cowpea, sow thistle, jimson weed, Florida beggarweed, and Florida pusley. Reniform nematodes are especially adapted for spread from field to field in contaminated soil clinging to farm equipment, tires, or the soles of shoes. Farm workers, cotton scouts, and other farm personnel should also make certain that all soil has been removed from their shoes upon leaving a reniform infested field. Nematicides are the best and most efficient means for controlling reniform nematodes in fields infested with reniform nematodes. Aldicarb at the higher recommended rates and 1,3-dicloropropene both provide economical return in infested fields.
