be induced, since they are continually interacting with microorganisms and insects. To
what extent plants in the fi eld are induced, and to what extent they can be further induced
by application of elicitors, is not known. Nevertheless, as indicated above, there are
many clear examples of induced resistance providing good levels of disease control in
a range of different cropping systems, particularly in situations where disease levels are
low to moderate. However, there must be a high probability that induced resistance will
be of economic benefi t to growers before it will fi nd widespread acceptance. Inducing
agents do provide a means to reduce fungicide inputs when used in rotation with fungi-
cides or as tank mixes with reduced rates of fungicide and activators such as ASM are
being integrated within existing disease management programmes. As our understanding
of induced resistance increases, so will the opportunity to exploit the phenomenon for
disease management within cropping systems.
