Pasteuria penetrans, an endospore‐forming obligate parasite of root‐knot nematodes, can be an effective biological control agent, particularly when used in pots, small plots or container‐grown crops. The absence of adequate mass‐production techniques prevents its deployment on a field scale. The spores are not mobile and their concentration and distribution influence parasitism since attachment of spores to free‐living juvenile root‐knot nematodes depends upon chance contact. Efficacy can also be influenced by the specificity of the population of P. penetrans to the root‐knot nematode population. If these problems can be overcome, the use of P. penetrans in integrated management systems developed over several crop cycles would appear to have good prospects for decreasing root‐knot nematodes in intensively cultivated soils.
