Early researchers identified key concepts and developed tactics for multiple option management of nematodes. Traditional management tactics include host resistance (where available), cultural tactics such as rotation with nonhosts, sanitation and avoidance, and destruction of residual crop roots and judicious use of nematicides. There have been advances in biological control of nematodes, but f...

Nematode management decisions should be based, in part, on knowledge of the damage threshold population density, and this value is likely to vary based on the level of resistance of the cotton cultivar. The damage functions of two cotton cultivars resistant to the root-knot nematode (Meloidogyne incognita) were compared with that of a susceptible cultivar in field microplots using a 3 x 7 facto...

Crop rotation and fallow are management options that can be used to control plant parasitic nematodes in forest tree nurseries. Before these options can be put into practice, it is important to determine the host range and survivability under fallow of the parasitic nematode to be controlled. The results of host range tests on a needle nematode (Longidorus spp.) and a stunt nematode (Tylenchorh...

Fluopyram is a succinate dehydrogenase inhibitor (SDHI) fungicide that is being evaluated as a seed treatment and in-furrow spray at planting on row crops for management of fungal diseases and its effect on plant-parasitic nematodes. Currently, there are no data on nematode toxicity, nematode recovery, or effects on nematode infection for Meloidogyne incognita or Rotylenchulus reniformis after ...

Determinatitm and use of economic thresholds is considered essential in nematode pest management programs. The economic efficiency of control measures is lnaximized when the difference hetween the crop valne and the cost of pest control is greatest. Since the cost of reducing the nematnde pnpnlation varies with the magnitutle of the reduction attempted, an economic (optimizing) threshold can be...
