Abstract: Screening, monitoring, and host-parasite interaction studies were conducted to evaluate the response of selected herbs to the most common root-knot nematodes in Florida. Basil (Ocimum basilicum), borage (Borago officinalis), oregano (Origanum vulgare), lavender fLavendula spica), rosemary (Rosamarinus officinalis), pot marjoram (Q. hortensis), sage (Salvia officinalis), sweet marjoram (0. maiorana), summer savory (Satureja hortensis) and winter savory (Satureia montana), seedlings were inoculated with Meloidogyne arenaria race 1, M. incognita races 1 and 3, and M. javanica. Results from our screening study shows that basil, sage, summer savory, lavender, and rosemary were susceptible, whereas oregano, pot marjoram and sweet marjoram were resistant to Meloidoayne spp. tested. Root-knot was the most common nematode and the one that increased the most on basil, sage and oregano in a Florida field. Most nematodes increased as the season progressed and decreased in the winter. Meloidogyne arenaria race 1 penetrated and established a feeding site in oregano roots. Hypertrophy was observed, hyperplasia limited, mature females were found in and out of the root.
