ABSTRACT
Many nematodes are parasites of plants and animals causing severe damage to crops and livestock. Many antihelminthics used to control animal-parasitic nematodes have created resistance in the nematode population, resulting in decreased control efficiency (Nansen 1993). Nematicides, the chemicals which are used to control plant-parasitic nematodes, are often toxic compounds causing both environmental and health problems. Several of these nematicides have been banned in many countries and the current process of phasing out the ozone-depleting substance, methyl bromide, which is an effective nematicide and insecticide, will increase the nematode problem in agriculture (Nordmeyer 1992). Therefore, the possibility to use nematophagous fungi for nonhazardous biological control of parasitic nematodes should be encouraged.
