Root-knot nematode (RKN) is a soil-dwelling microscopic roundworm. This nematode is parasitic on numerous plants, including vegetables, fruits, field crops, ornamentals, and common weeds. RKN can occur in commercial and homeowner plantings. Frequently, the nematode interacts with other plant pathogens to form a disease complex in which the resulting disease is much more severe than that caused by either component alone. Rootknot nematode is particularly serious when high populations are allowed to build up due to continuous replanting of susceptible plants on the same site. The Whitley County ANR agent worked with a commercial vegetable producer to address a RKN issue in a seasonal high tunnel.  The ANR agent took the producer to a neighboring county to observe a bag culture system implemented in response to similar RKN issues.  The ANR agent networked with specialists, fellow agents, and commercial growers to help the producer implement a bag culture system that has resolved the RKN issues in his high tunnel.
