10.5.2 FUSARIUM VERTICILLOIDES
Intensity of
F. verticilloides
is increased at drought stress condition, which
is determined by the frequency and duration of drought (Paica et al.,
2013). Mycotoxin production due to
Aspergillus
is also increased under
such circumstances.
10.5.3 CRONARTIUM RIBICOLA
The blister rust of pines is favored cooler climate and spread of basidio-
spores is driven by moisture, air circulation and temperature (Van Arsdel,
1965). Events related to the frequency of 100% RH and changes in tem-
perature influence the disease cycle of
C. ribicola
.
10.5.4 PHYTOPHTHORA RAMORUM
Larger lesions are developed in spring on coast live oaks infected with
P. ramorum
. The synchrony between host cambium activity (host phe-
nology) and pathogen colonization rate (sporulation of the pathogen) are
likely to be affected by climate shifts (Donnelly et al., 2011). Likewise,
the climate changes adjust the pattern of susceptibility to
P. ramorum
in
ecosystems (but not currently affected) at risk (Brasier and Webber, 2010;
Tubby and Webber, 2010).
10.5.5 PHYTOPHTHORA CINNAMOMI
Moisture, pH and temperature influence growth and reproduction of
P.
cinnamomi
(soilborne nature). Bergot et al. (2004) predict that raised
mean temperature will lead to a potential range expansion of
P. cinna-
momi
. Similarly, larger mean winter temperature, shifting of seasonal pre-
cipitation from summer into winter supports infection by
P. cinnamomi
in
Central Europe.
