Abstract

A soil
solarization experiment was carried out in a seven years old commercial olive
orchard naturally infected with Verticillium dahliae in
western Anatolia. Solarization was applied to individual trees for either one
or two successive years. The maximum temperature was recorded in solarized soil were 42.9 and 44.4
ºC in the first and second year’s application respectively. Solarization
slightly reduced the mean severity of wilting in both years without a
statistical significance between treated and control trees. In one-year
solarization, the percentage of recovery exceeded the natural recovery in
control trees while double-solarization couldn’t supply a significant additive
effect in improving the health of olive trees.
