أجري البحث لدراسة تأثير التشميس في فطور تربة البيوت المحمية , و تضمنت الدراسة أربع معاملات : شاهد , تشميس 30 , 40 , 50 يوماً, و على أعماق 0 , 5, 10, 15 و 20سم , مع تغطية معاملات التشميس بغطاء شفاف من البولي إيتيلين. و نفذ البحث في جامعة تشرين ضمن بيت بلاستيكي مساحته 350 م² لموسمين زراعيين2007 -2008, 2009-2008.
This investigation was carried out in a plastic house (350 m² area) located at Tishreen University in two seasons 2007-2008 and 2008-2009, to study the effect of soil solarization in soil borne fungi in greenhouse. With four treatments: the control treatment, Soilsolarization: 30, 40, and 50 days, and 0, 5, 10, 15 and 20 cm depth. The solarized soil covered with transparent polyethylene.

The study was carried out to comparison between of of three controlling treetments,
of soil-borne fungi in greenhouses. The treetments were as follows: An treeted control,
Formalin 3%, soil Solarization + animal manur and solarization for 50 days, and 0 , 5, 10
,15 and 20 cm depth.
Root rot is considered one of the serious widely spread tomato diseases in
plastic houses culture of Syria. Soil solarization, using transparent polyethylene
(PE) covering, was applied during July and August (١٩٩٤-١٩٩٦) in Tartoos
governorate for
controlling soilborne pathogenic fungi. Results indicated that,
native fungal populations in covered moist soil supplied with or without sulfur
were significantly reduced in comparison with the uncovered treatment.
A study of effectiveness of methyle bromide (MB) and two of its alternatives were
carried out to evaluate their impact on soil sterilization, the density of nematode
and on the growth and production of carnation crop. The experement was carried
ou
t in two plastic houses of 400m2 in Zabadani region during 1999-2000.The
treatments were as follows; MB(28g/m2), metam sodium (75cm3/m2), soil steaming
and control. The results showed significant-differences between the control and the
treatments, where the effectiveness of reducing the density of nematodes were
55.6%, 53.4%, 69.9% and 0% respectively. The soil steaming treatment encouraged
the plant vigour and harvest started earlier, but the average number of carnation
flowers for the different treatments were 28.3, 23.9, 32.8 and 23.8 (flowers during
each harvest day) respectively. Confirmed differences were found for yield, where
the highest number of carnation flowers were found in the plots treated with metam
sodium, and therefor we recommend using metam sodium as a part of integrated
pest management program of nematodes in carnation cultivatar.
In the summer of ١٩٩٨ at the Kearney Agric. Center-University of
California, two experiments were carried out to evaluate solarization methods
for disinfestation of nursery soil from soil born fungi and nematodes. On
rototilled sandy loam soil, ٢m
٢ x ٢٠cm high beds were shaped into place, each
experiment had ٥ treatments with ٣ replications, tow treatments received the
double tent over black or silver plastic. The other ٢ treatments had single tent.
In addition, a nontreated control was placed in the shade.
A Study was carried out to evaluate the impact of some insecticide.
The results showed that no effects on growth of the studied fungi
were observation when Deltamethrin and Chlorpyrifos were used by
the low concentration.
