The sugarbeet cyst nematode (SBCN), Heterodera schachtii Schmidt, is a major root parasite of sugarbeet (Beta vulgaris L.). It causes serious stand and yield reductions wherever sugarbeet is produced, particularly with fields located near refineries where sugarbeets have been grown consistently for many years. The objective of this research was to evaluate the economics of growing nematode resistant, trap crop radish (Raphanus sativus L.) as a second crop following malt barley for control of the SCBN, either with or without grazing lambs. Field studies provided a basis for an economic analysis of a representative farming operation in the Big Horn Basin of Wyoming. Growing radish as a second crop following barley cost $223 ha -1 less than purchasing and applying nematicide; and increased the net return as a percent of land value, from 3.9% to 5.9%. Grazing lambs helped defray the cost of growing trap crop radish, increasing the rate of return to 9.3%.
