Abstract

The effectiveness of soil solarization and or fungi biological control
(Trichoderma harzianum) against fusarium wilt and root-knot nematode
diseases in musk melon was tested. This research has been implemented under
field conditions in Dier Ezzor governorate in the east side of Syria. Results
showed an increase in temperature at the depth 5 - 20 cm after 60 days of
covering with transparent plastic grading between 12.3 - 19.30C. The
effectiveness of soil solarization alone or when incorporated with fungi
(Trichoderma harzianum) reached 99% for fusarium fungi populations. The
solarization inhibited fusarium fungi successfully preventing pathogen
population recovery for 90 days after planting; where the activity reached
96.4%. However, no fungi was found at the same time by incorporation
solarization with Trichoderma harzianum. The general average of reproductive
unit of the root-knot nematode was affected in the solarized soil at the same
prior time and depth where activity reached 96%. The rate of injury of plants
with fusarium wilt diseases decreased in solarized soil or in sectors of treatment
in corporation with fungi significantly and eventually and did not surpassed 5.2-
3.9%, respectively, compared to control (100%) The rate of injury the root-knot
nematode diseases decreased in the same treatments to 4.9-9.4% compared to
100% in control. The solarization and fungi treatment increased the
characteristics and final yield of musk melon yield.
