تم اختبار ثلاثة مبيدات فطرية جهازية هي fenarimol, triflumizol , وtriadiminol بالتراكيز (الجرعات) الموصى به أو نصفها, مع أو دون مزج بالزيت المعدني( بمعدل 300 مل زيت/100 ليتر ماء ) لدراسة تاثير هذه المعاملات في مرض البياض الدقيقي على البندورة المحمية. أظهرت النتائج دوراً هاماً للزيت المعدني في تحسين تأثير المبيدات المدروسة من خلال خفض نسبة وشدة الإصابة بالمرض عند الاستعمال بالجرعات الموصى بها حتى عند الاستعمال بجرعات قدرها نصف الجرعات الموصى بها حيث كانت نسبة الإصابة بالمرض المذكور بعد شهر من المعاملة تحت تأثير تطبيق نصف التراكيز الموصى بها من هذه المبيدات لوحدها دون المزج مع الزيت 65.2 – 75.7% وشدة الإصابة 62.7 - 77.3% في حين انخفضت نسبة الإصابة عند المزج مع الزيت إلى 44.5 – 48.6% وشدة الإصابة إلى 16.9- 45.8%
Three systemic fungicides fenarimol, triflumizol, and triadimenol were used (mixed with mineral oil at 300 ml/100 L water or not) to evaluate the effects on powdery mildew of tomato in greenhouse. Results showed important role of mineral oil in inhancing the studied fungicides's effects by decreasing infection percentage and severity of the disease if the recommended doses are used or half of them. when these fungicides were used in low rates (50% of the recommended doses without mineral oil) infection percentage after a mounth of treating were 65.2 - 75.7% and severity 62.7 – 77.3% wherease when the fungicides were used with oil the infection percentage were decreased to 44.5 - 48.6% and severity to 16.9 – 45.8%

Research summary
تتناول هذه الدراسة تأثير مزج الزيت المعدني مع ثلاثة مبيدات فطرية جهازية هي triflumizol، fenarimol، و triadiminol في مكافحة مرض البياض الدقيقي على البندورة المحمية. أظهرت النتائج أن الزيت المعدني يلعب دوراً هاماً في تحسين فعالية المبيدات الفطرية من خلال خفض نسبة وشدة الإصابة بالمرض. عند استخدام نصف الجرعات الموصى بها من المبيدات مع الزيت، انخفضت نسبة الإصابة بشكل ملحوظ مقارنة باستخدام المبيدات وحدها. تم تنفيذ التجربة في بيت بلاستيكي في طرطوس، سوريا، خلال موسم 2011/2012. أظهرت النتائج أن مزج الزيت المعدني مع المبيدات الفطرية يحسن من تأثيرها في مكافحة المرض، مما يمكن أن يقلل من كمية المبيدات المستخدمة ويوفر تكاليف الزراعة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين كفاءة استخدام المبيدات الفطرية في مكافحة مرض البياض الدقيقي على البندورة المحمية. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة. أولاً، الدراسة تركز بشكل كبير على الجانب التجريبي دون تقديم تحليل اقتصادي مفصل لتكلفة استخدام الزيت المعدني مقارنة بالمبيدات الفطرية وحدها. ثانياً، لم يتم التطرق إلى التأثير البيئي لاستخدام الزيت المعدني على المدى الطويل. وأخيراً، كان من الممكن توسيع نطاق الدراسة لتشمل أنواع أخرى من المحاصيل والفطريات للحصول على نتائج أكثر شمولية.

To evaluate the effects of summer mineral oil which were mixed with tow systemic commercial fungicides Flint and Trifmine on some tomato yield properties in Syrian coast greenhouse conditions, the tow fungicides were supplied at the recommended doses
(mixed with mineral oil or not), the results showed no negative effctes on the plant flowers, fruits, fruit's weight through the study; there were 71.0-75.0 fruits on each plant and fruit's weight was 75.3-87.2 g/one fruit in treatments which fungicides were not mixed with mineral oil, 69.1-76.4 fruits on each plant, 74.8-81.2 g/one fruit in treatments which fungicides were mixed, compairing with 62.2 fruits/plant in control, 87.6 g/fruit in control, differences were not significant.
To know the effect of some fungicides on peacock eye disease has beentested five
fungicides from different chemical groups, using concentrations advisable to field
application,on the 45 year old olive trees in the Baksa village Lattakia . The resul
ts
showed an increase in incidence of the control of 22.4 to 45.5 % after 45 days, versus low
incidence rates in the fungicides tested treatments . The best two fungicides were
thiophanate –methyl with infection decreasing from 19.2 to 10.3% and chlorothalonil from
24.3% to 16.5% . The severity also decreased in the treatment of the fungicide thiophanate
–methyl from 9.7 to 4.1 % and chlorothalonil from 13.7 to 8.9 % while the severity of the
infection of the control increased from 10.5 to 25.6 % .In order to efficiency the fungicide
thiophanate – methyl was more effective reducing the infection severity compared with the
control with 82.8 %, followed by chlorothalonil , kresoxsim methyl , and mancozeb with
73.3 , 72.0 , 71.9% respectively whereas the fungicide copper oxychloride was the least
effective with 68.1%.
WI٢٢٩١ and Tadmor, two barley lines widely grown in the Mediterranean
region were tested for powdery mildew (Erysiphe graminis f. sp. hordei)
resistance together with the European differential tester set against six powdery
mildew isolates. The si
x cultures of powdery mildew developed from single
colonies were comprised of four powdery mildew isolates originating from Syrian barley lines and two cultures originating from Danish barley lines.
This search carried out to study the effect of treatment with some fungicides
(mancozeb + metalaxyl - M, chlorothalonil ،azoxystrobin and mancozeb) in
control late blight (Phytophthora infestans Mont.) on potato va. Spunta and
yield in homs during
two seasons 2008 and 2009. The results showed that the
use of a mixture of fungicides (mancozeb + metalaxyl - M) gave the superior
efficacy in controlling the disease during two seasons compared with other
treatments. The percentage of effect (74.32% and 57.24%) during 2008 and
2009, respectively. While, the fungicides (mancozeb) gave the lowest effect in
controlling the disease during two seasons, where as the percentage of effect
(31.95% and 40%), respectively. Recorded results showed that spray of potato
plant with tested fungicides increase the yield compared with untreated plants.
The mixture fungicides (mancozeb + metalaxyl-M) increase in yield (35.55%
and 32.285) during 2008 and 2009, at respectively. We can arrange the tested
fungicides according to their the efficacy in controlling the disease and in
increase the yield such as following: mancozeb +metalaxyl-M> chlorothalonil>
azoxystrobin> mancozeb.
The experiment was carried out during2013-2014 Miaar Shaker village (Tartous) to determine the best method of irrigation on growth and productivity of Tomato plant in plastic green-house. Three method of irrigation were used in the experiment :(furro
w surface , surface drip and subsurface drip irrigation). Growth of plants, productivity and fruit quality were studies.
The results showed that surface and subsurface drip irrigation give more plant growth (leaves number and leaves area) more flowering and fruit production as compared with furrow irrigation method .The leaves number and leaves area in plant with surface drip irrigation was 31.49 leaves and 17078/plant while these number reached only to 22.91 leaves and 7057.86/plant in the furrow irrigation with significant difference . The productivity of plants was also higher in surface drip irrigation method(4.75 kg/ plant) without significant difference as compared with subsurface irrigation method and with significant difference as compared with furrow irrigation method (3.95 kg/ plant). The quality of fruits was better in surface drip irrigation (8.28% dry material ,5.02% TSS and 28.23mg vitamin c /100g) in fresh matter while these number were 7.18%, 4.98% and 20.96 mg/100g in furrow .
The irrigation method haven't affect in the: plant length ,and acidity percentage.
