Abstract: The effects of Multiguard Protect, a commercial formulation of furfural, on plant growth, nematode populations in roots and soil, and galling caused by Meloidogyne spp. were assessed in two greenhouse trials. 'Tiny Tim' tomato (Lycopersinon esculentum) and 'Capistrano' bell pepper (Capsicum annuum) were transplanted into pots containing field soil naturally infested with a mixed population of root-knot nematodes, as well as other pathogenic and microbivorous nematodes, and soil microorganisms. Multiguard treatments were applied as soil drenches at: 1) 452 kg/ha 7 days preplant; 2) 452 kg/ha 7 days preplant + 28 kg/ha 2 weeks post-plant; 3) 85 kg/ha 7 days preplant; 4) 85 kg/ha 7 days preplant + 28 kg/ha 2 weeks post-plant; 5) 28 kg/ha 2 weeks post-plant; 6) untreated control. The experiments were performed twice, once in fall 2005 and repeated winter 2006. No phytotoxicity or root disease, other than galling, was observed on either crop with any treatment. Multiguard significantly increased root-knot and other parasitic nematode populations in both roots and soil at 452 kg/ha in tomatoes and peppers in the fall trials compared to the untreated controls and lower rates Multiguard. However, galling was still significantly reduced on tomato at the 452 kg/ha rate in both trials. Galling on pepper was significantly lower than tomato and was not reduced by Multiguard treatments in either experiment. At high rates, Multiguard appears to have an effect on either the host plant or the nematode that inhibits gall formation in tomato.
