various organic amendments. Here, a renewed interest evolves in using nematode-
trapping fungi, partly due to an increased knowledge on the biology of these fungi
and partly due to better methods of formulation and application of fungal biocontrol
agents to the soil. Commercial production of some of these fungi was started and
used in France. These are
Arthrobrotrys robusta
variant “Antipolis” marketed as
'Royal 300' (Cayrol et al.
1978
) and 'Royal 350' of
A. irregularies
for controlling
root knot nematodes on tomato (Cayrol and Frankowski
1979
). Stirling and Smith
(
1998a
) developed formulation of nematode-trapping fungi for the control of root
knot nematodes in microcosm. Our laboratory experience also showed that it is
possible to develop mass culture of nematode-trapping fungi on some cheap solid
substrates with long shelf life (unpublished data).
