Glomerella leaf spot (GLS) in Brazil can potentially lead to severe
defoliation (above 75%) of apple plants (descended from the ?Golden Delicious?
group such as ?Gala?), reducing the yield and weakening the trees. In addition, the
production costs can increase by approximately 20% due to the application of fungicides,
main strategy of control of the disease. GLS is a disease caused by the fungi Colletotrichum
spp., and presents an incubation period short, approximately two days after infection, which
difficult many the manage of the disease. Mango wilt causes the death of the entire tree,
either a few months after the fungus penetrates the roots or more slowly if it enters through
wounded branches of the canopy caused by insect vectors. The use of mango cultivars
showing non-race-specific resistance to Ceratocystis fimbriata infection (causal agent of
the disease) is the most effective strategy that has been adopted by the growers to control
mango wilt, mainly because chemical control was not shown to be efficient. However, due
to the great genetic variability of C. fimbriata, resistant cultivars may become susceptible in
a short period. The difficulty of managing of the fruit tree diseases with resistant cultivars,
cost increase with fungicides, and environmental and health concerns have fostered the
development of eco-friendly technologies for plant protection, such as compounds that can
induce plant resistance.
