ABSTRACT
Fungi often suppress their competitors, including agricultural pests, via predation, parasitism, and antagonism. These suppressive mechanisms have evolved so that fungi may compete for food and space against their competitors. Such mechanisms may be very complicated and could be investigated from various aspects, such as pathology, ecology, epidemiology, and histology. General information on this topic can be found in two excellent books [3,4]. This chapter attempts to provide readers with an update on the role that secondary metabolites play in fungal biopestcides.
