Verticillium wilt is one of the most serious disease that affect olive trees, and it is spread all over the world where the olive trees grown. It is caused by the soil – borne fungiVerticilliumdahliaekleb. Whichhas a wide host range, and forms amicroseclerotia that survive for long time in the soil.and it is difficult to manage. In this studya survey was carried out in order to determine the incidence and severity of infection on olive trees in Lattakiaduring2015. The results showed that the highest percentage of infection and severity were on the Kaissicultivar in ALqurdaha (10.68% , 4.05%) respectively , and the lowest percentage of infection and severity were on the Safrawicultivar in ALqurdaha (3.92% , 0.97%) respectively.

Research summary
تتناول هذه الدراسة مرض الذبول الفرتسليومي الذي يصيب أشجار الزيتون، وهو مرض خطير ينتشر في معظم مناطق زراعة الزيتون حول العالم. يسببه الفطر Verticillium dahliae الذي يعيش في التربة وله نطاق واسع من العوائل. تم إجراء مسح حقلي في محافظة اللاذقية خلال عام 2015 لتحديد نسبة وشدة الإصابة بهذا المرض على أشجار الزيتون. أظهرت النتائج أن أعلى نسبة إصابة كانت على صنف قيسي في منطقة القرداحة بنسبة 10.68%، بينما كانت أقل نسبة إصابة على صنف صفراوي في نفس المنطقة بنسبة 3.92%. تشير الدراسة إلى أن جميع أصناف الزيتون المزروعة في المحافظة قابلة للإصابة بالمرض بدرجات متفاوتة، حيث كان صنف صفراوي الأقل قابلية للإصابة وصنف قيسي الأكثر قابلية. توصي الدراسة بمتابعة دراسة المرض سنويًا وتقييم الفاقد في الغلة الناتج عن الإصابة، بالإضافة إلى دراسة تأثير العوامل البيئية على نسبة وشدة الإصابة.
Critical review
تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على مشكلة خطيرة تواجه زراعة الزيتون في محافظة اللاذقية. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق المسح ليشمل مناطق أخرى في سوريا، مما يمكن أن يوفر صورة أكثر شمولية عن انتشار المرض. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر فائدة إذا تضمنت تجارب ميدانية لاختبار فعالية مختلف طرق المكافحة المقترحة. كما أن الدراسة لم تتناول تأثير العوامل المناخية بشكل كافٍ، وهو ما يمكن أن يكون له تأثير كبير على انتشار المرض.

The research aims to study the economic efficiency of olive mill wastewater (OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in Lattakia Governorate, depending on the descriptive analytical method,And found the results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP , The coefficient of profitability compared to the cost of production (about 41.32%)%, while the profitability coefficient was compared to the capital invested approximately 42.98%.
A survey of Tomato spotted wilt virus (TSWV, Tospovirus, Bunyaviridae) on some solanaceous crops and associated reservoir weeds was conducted between March and November 2013. 983 field samples was collected (703 Solanaceous crops, 280 associated w eeds), and 218 greenhouse samples (190 Solanaceous crops, 28 associated weeds). Tissue Blot Immunobinding Assay TBIA were performed to detect TSWV. Results of TBIA of tested samples showed the natural infection of TSWV in Lattakia by 22,06%. The percentage infection in field crops was 8,82% on solanaceous crops and 62,5% on associated weeds and It was in greenhouse crops 2,11% on solanaceous crops and 85,71% on associated weeds. This is the first report in Syria of Tomato spotted wilt virus on Tobacco, Eggplant, and several weeds.
A field survey for chickpea wilt disease Fusarium oxysporum f.sp ciceris was conducted in different provinces of north Syria during 2011 cropping season with the objectives to determine chickpea wilt distribution and factors affecting its develop ment. Two hundred and fifty samples were collected from Alhasakah, Aleppo and Idleb fields. The results showed varying levels of incidence between and within provinces (2-90%), and the highest incidence was recorded in Alfouaa- Idleb (90%). The incidence and distribution of this disease seemed to be affected by many factors especially date of sown and soil kind. The pathogenicity test of 60 isolates related to Fusarium oxysporum on susceptible cultivars Ghab1 was shown that 54 isolates related to Fusarium oxysporum f. sp. ciceris; 32 isolates of them were caused yellowing symptoms and 22 were caused wilting symptoms.
The research was conducted during the period between May 2014 and May 2015. The field work was carried out in the Astamo area of Lattakia within an orchard planted with citrus and olives in the form of single and adjacent sectors for each
This research carried out in the orchards of the Stamo area province of Lattakia citrus during the years 2014-2015, and the results of the study showed that the insect black cortical one generation per year with a second partial generation during t he summer. Under the insect overwintering nymph stage in the second age is the most able to withstand the low-temperature phase in the winter. Mermaid back age-second activity in the beginning of spring to complete their life cycle where the female young appear in early April on each of the branches and leaves, to show adult females with the beginning of the month of May and starts the eggs to hatch in the middle of this month and will continue until the month of July. The study found that the nymph stage second phase age is the most common during the season at each of the branches and leaves. Observed the death of large numbers of the insect in the phasic nymph third age and female fledgling stage, which evolved during the same season, as the study of the distribution and the spread of the different phases of the insect on the plant parts showed that the branches were more injury than securities with higher than moral in the population density of the presence of eccentric nymph and adult stages the branches compared with the leaves.
