بحث عن بديل لاستخدام بروميد الميثيل في تعقيم التربة ضد العوامل الممرضة للنبات و ذلك باستخدام التشميس، تم تنفيذ تجربتين في مركز كريني للبحوث العلمية الزراعية جامعة كاليفورنيا صيف ٢ م بفاصل ١ م تتكون كل منها من × ١٩٩٨ . قسمت الأرض في التجربتين بعد تحضيرها إلى قطع ١ خمس معاملات تتكرر ثلاث مرات، ُ غطيت جميع معاملات التجربتين برقائق البولي إيتيلين الأسود اللون أو الفضي وفق المخطط. تم تغطية كل معاملتين من كل مكرر بخيمة واحدة من البولي إيتيلين الشفاف بينما ُ غطيت المعاملتين الأخريتين بخيمة من مضاعفة يفصل بينهما أقواس معدنية.
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, ٢m٢ 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.

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.
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.
plants plays an important function in alive environment and
generally in architecture, and it has an important function in the
formation of constructional spaces that the constructional masses
appears in their real scales and it is interrelated wi

Plants and trees have important functions in all social economic
environmental aspects, in addition to their great function in
controlling sunshine and changing many hard climatic conditions,
and they have a great function in dilution the global warming which
has become a global phenomenon that the whole world is seeking to
solve.
TMP-SMX is the first choice drug to prevent Pneumocystis jiroveci pneumonia
(PCP) in hemato-oncology patients. The utilization of alternative drugs (Pentamidine – Dapsone) was
suggested in some protocols in hemato-oncology. It seems that there is a
n increase in the utilization of
alternative drugs. The aim of the study was to evaluate the utilization of different drugs to prevent PCP
and to identify the reasons which lead to the utilization of alternative drugs.
A study of the effectiveness of methyl bromide (MB) and some alternatives
were carried out to determine their effects on soil sterilization, densitY of
nematode and production of tomato (variety Karam) crop, under greenhouses
conditions in Banias
area, during 1999-2000.The treatments were as follows:
MB (57g/m2), Dazomet GR 98%, organic matter + solarization (Biofumigation)
and control. Results showed that the effectiveness in reducing the
total nematode density were 97.5%, 66.1%, 28.8 and 0% respectively. The root
knots index for Meloidogyne spp. were 0, 0.64, 0.83 and 1.83 respectively. The
Bio-fumigation treatment didn't have any effect on reducing the nematode
density, but increased the plant growth and yield. The crop yield were 190.67,
167.33, 185 and 157.67.kg/plot respectively and there was no significant
difference between the MB and the Bio-fumigation treatments.
