The activation of defensive responses of plants is a promising tool for controlling
pests in conventional agriculture. Over the last few years, several compounds have been studied
to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These
compounds have the ability to induce a priming state on the plants that results in resistance (or
tolerance) against subsequent infection by a pathogen. In terms of molecular response, induced
plant defense involves a broad number of physical and biochemical changes such as callose
deposition or phenolic compounds, activation of salicylic and/or jasmonic acid pathways or synthesis of defense-related enzymes. Despite the large number of studies performed to ascertain
the physiological and biochemical basis of induced resistance, only a few resistance-activating
compounds have been studied as a real alternative to classic means of control and the studies geared towards incorporating induced resistance into disease management programs are
relatively rare. The incorporation of natural resistance inducer in pest management programs
of woody crops, alone or in combination with classical methods, could be a reliable method for
reducing the amount of chemical residues in the environment. In this review, we discuss the
current knowledge of induced resistance in woody crops, focusing on the mode of action of
compounds authorized for conventional agriculture. We conclude by discussing the environmental and economic advantages of applying resistance inducers to conventional agriculture with
special emphasis on natural compounds. [-]
