Abstract |
: |
Two experiments were held to test the effect of solarization
as a disinfestation non-chemical method of peat moss, a potential
source of pathogenic fungal inocula. Solarization took place in spring
and summer, 2004, of transparent polyethylene bags filled with artificially
infested sphagnum peat moss with Pythium aphanidermatum
and Fusarium oxysporum. Average daily maximum temperatures of
solarized bags at five cm deep reached 51 and 54.2?C in the spring
and summer experiments, an increase of 16.8 and 16.9?C, respectively,
over temperatures of non solarized shaded bags. In the
summer experiment, all tested pathogens were completely eliminated
within two days at both depths, surface at 0-7.5 cm and inner layer of
peat moss, 7.5-15 cm. In the spring experiment, however, F. oxysporum
survived solarization better than P. aphanidermatum. It took
six and eight days to eliminate the former at the surface and inner
layer of the peat moss bags, respectively. The latter, on the other
hand, took two and six days to be eliminated, respectively. The number
of both fungi was significantly not affected in the shaded bags
with a fluctuation in the population. Solarization of peat moss in clear
plastic bags is a very efficient, economical, safe and easy method to
eradicate plant pathogenic fungi even at cooler seasons. |
