From Conclusions and future directions :

"Although a high-sugar level does not always boost the immune system in plants, since we know pathosystems, in
which a high-sugar level stimulates the development of the
pathogenic fungi (the so-called high-sugar diseases��"
Horsfall and Diamond 1957), in most plant species, particularly those important in agriculture, sugar enhances
resistance. As it was mentioned earlier, sugar transporters
are key elements, necessary for the formation of the secondary sink at the site of fungal pathogen invasion. The
information that certain sugars may act as priming agents
may also be useful in programs to generate stress-resistant
cultivars. Moreover, certain sugars may prove an effective
substitute to toxic pesticides."
