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 out 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.

Research summary
تتناول الدراسة فعالية بدائل بروميد الميثيل في مكافحة الديدان الخيطية في بيوت بلاستيكية مزروعة بالقرنفل في منطقة الزبداني خلال الفترة 1999-2000. تم استخدام أربع معالجات: بروميد الميثيل (28 جم/م²)، ميتام صوديوم (75 سم³/م²)، تبخير التربة، ومعاملة الشاهد. أظهرت النتائج فروقاً معنوية بين المعالجات والشاهد، حيث كانت فعالية تقليل كثافة الديدان الخيطية 55.6%، 53.4%، 69.9% و0% على التوالي. شجعت معاملة تبخير التربة على نمو النباتات وبدء الحصاد مبكراً، لكن متوسط عدد أزهار القرنفل كان 28.3، 23.9، 32.8 و23.8 زهرة لكل يوم حصاد على التوالي. أوصت الدراسة باستخدام ميتام صوديوم كجزء من برنامج الإدارة المتكاملة للآفات في زراعة القرنفل.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال مكافحة الديدان الخيطية باستخدام بدائل بروميد الميثيل، إلا أنها تفتقر إلى تحليل اقتصادي لتكلفة كل معاملة مقارنة بالعائد الاقتصادي من الإنتاج. كما أن الدراسة لم تتناول تأثير هذه المعالجات على البيئة والصحة العامة بشكل كافٍ. كان من الأفضل تضمين دراسات طويلة الأمد لتقييم التأثيرات البيئية والصحية لهذه البدائل. بالإضافة إلى ذلك، لم يتم التطرق إلى إمكانية استخدام تقنيات أخرى مثل المكافحة البيولوجية كجزء من الإدارة المتكاملة للآفات.

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.
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.
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.
The study was conducted in Jableh during 2012/2013 in plastic green house on sweet and hot pepper hybrids to study the effect of plant density on growth and productivity. The hybrid VIGARIO(sweet pepper) and hybrid ERAD (hot pepper)variety were ap plied in six treatment and four replication .It was showed that the highest number of flowers were recorded in VIGARIO variety in space (50x60)cm to amount(18.33) flower/plant ,while the the highest number of fruits were recorded in space(50x40)cm to amount(20.98)fruit/plant and the earlest yield (390.6)g/m2and the highest total (3486)g/m2productivity were found in space (50x40)cm . IRAD hybrid give the highest number of flower in space (50x40)cm to amount(28.23) flower/plant,while the hieghest number of fruit were recorded in space (40x60)cm to amount(107.17) fruit/plant and the highest productivity were found in space(50x40)cm to amount (9485.7)g/m2.
In previous years, the Government depended on deficit financing system, which inflame the inflation in Syrian economy. In view of negative results which result from that, We -in our research- have put an frame to determinate all financing alternat ives otherwise deficit financing system. Looking for alternatives to finance development process, on the first side decreases the load on public budget, as it decreases the using of foreign loans, or withdraw the money from the central bank (deficit financing),and on the other side it attains the partnership principle with the privet sector in financing the development process in the country. We demonstrate the position of traditional and islamic economy from using deficit financing system, and illustration the deferent available alternatives of financing, and their positives and negatives, and which we recommend to reliance on to financing development process.
