- 요약Weed interference with sweetpotato can reduce yield and leave it susceptible to pathogens and insects. Guava root-knot nematode (Meloidogyne enterolobii) is an emerging pest in North Carolina. Guava root-knot nematode can severely impact sweetpotato yield and quality. In addition, it is known for its aggressive nature, having a wide variety of both weed and crop hosts. Research was conducted to evaluate which weeds may act as a host for root-knot nematodes and identify herbicides which could be registered to control identified weed hosts in sweetpotato. In addition, yellow nutsedge (Cyperus rotundus L.) is a troublesome pest. However, there are few options for yellow nutsedge control in organic production systems. Research was conducted to develop a management program utilizing subsequent mowing and herbicide applications to improve yellow nutsedge control.A survey was conducted to identify which weeds may be acting as a host for root knot nematodes in sweetpotato producing counties in North Carolina. Summer weeds were excavated, then the roots were cleaned and examined for the presence or absence of root-knot nematode galling. The weed species with the highest prevalence across fields sampled and root-knot nematode incidence rate were: annual morningglory (Ipomoea spp.), prink purslane (Portulaca pilosa L.), carpetweed (Mollugo verticillata L.), Palmer amaranth (Amaranthus palmeri S. Watson), and Florida pusley (Richardia scabra L.).
