أجري مسح حقلي في الفترة الممتدة بين شهري آذار و تشرين الثاني لعام 2013 بهدف تقصي انتشار فيروس الذبول المتبقع للبندورة Tomato spotted wilt virus ( TSWV، جنس Tospovirus، عائلة Bunyaviridae) على بعض محاصيل العائلة الباذنجانية المزروعة إضافة لبعض الأعشاب البرية المرافقة لهذه المحاصيل. تم جمع 983 عينة (703 عينة من محاصيل العائلة الباذنجانية، 280 عينة من الأعشاب المرافقة للمحصول) و ذلك في الزراعات الحقلية المكشوفة، كما جمعت 218 عينة من الزراعات المحمية (190 عينة من محاصيل العائلة الباذنجانية، 28 عينة من الأعشاب المرافقة). اعتمد في التشخيص اختبار البصمة النسيجية المناعية TBIA. بينت نتائج الاختبارات المصلية وجود فيروس الذبول المتبقع للبندورة طبيعياً ضمن العينات المختبرة بنسبة وصلت إلى 22.06% على مستوى المحافظة. بلغت نسبة تواجد الفيروس في عينات الزراعات الحقلية 8.82 %على محاصيل العائلة الباذنجانية و 62.5 %على الأعشاب المرافقة. أما في الزراعات المحمية فقد سجل تواجد الفيروس بنسبة 2.11% على محاصيل العائلة الباذنجانية و 85.71% على الأعشاب المرافقة لها. يعد هذا البحث التقرير الأول لتسجيل هذا الفيروس على محصولي الباذنجان و التبغ في سورية و كذلك التسجيل الأول له على عوائل عشبية عديدة.
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 weeds), 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.

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 amic
roseclerotia 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.
Afield survey of ckickpea chlorotic stunt virus (CPCSV) was conducted in some plantation areas in Lattakia province. A total of 252 samples were collected from plants showing chlorotic and stunting symptoms from 54 field. Results of Tissue Blot Immun
obonding Assay has shown the presence of CPCSV in some plantation areas. The percentage of CPCSV varied in samples collected from fields, the highest percentage was 33.33% in Ras-elain aria and the lowest was 7.69% in Elbourjan aria.
This study was carried out to evaluate the effect of isolates of Rhizobium
leguminosarum in reducing infection of tomato with Fusarium oxysporum
f.sp.lycopersici,the causal agent of tomato wilt. The results demonstrated significant
reduced in seve
rity disease of plants were inoculated with Rhizobium leguminosarum, the
rate reduced of disease severity was 69.21% and in length of browning was 35.14%.
Rhizobium leguminosarum increased of plant height with 21.01%, fresh weight of shoot
and root increased with 35.32% and 43.35% respectively,while increased the number of
fruit with 47.39% and its weight with 32.48%
The accuracy of the taxon T. cinnabarinus (Boisduval 1867) as a distinct species, or
as a synonym of Tetranychus urticae Koch 1836, is still standing as a controversial issue of
taxonomy and as a point of discussion. T. cinnabarinus and T. urticae
have been regarded
in the first stage of this study as one species, and it was characterized depending on the
distinctive characteristics of both genders. In the second stage, the two species were
distinguished according to many morphological characters that have been recommended by
authors cited T.cinnabarinus as a valid species. The efficiency of some measures adopted
to distinguish both T. cinnabarinus and T. urticae were also tested. Measurements didn't
match local samples that showed obvious differences, T. cinnabarinus & T. urticae are not
likely to be considered as two different species according to recent researches. Both T.
cinnabarinus and T. urticae were detected on various wild and cultivated host plants. One
hundred samples of plants presented symptoms of tetranychid attacks were collected from
different localities in Lattakia province. Both T. urticae and T. cinnabarinus were found on
29, 9 samples, respectively.
Remote sensing is one of most important technology that provides information on
large areas in a short time. The study was carried out in Sweida governorate with the
aim of calculating the area of strategic crops and its distribution for the agricu
ltural
season 2014/2015 by classifying satellite images-type (BKA). The images were
received by the station at General Organization for Remote Sensing in Damascus,
Syria. The spatial resolution of the satellite BELARUSIAN SPACECRAFT is 10.2
meters. The results showed that the spread of the three crops (wheat, barley and
chickpea) was generally on the four sides of the governorate, especially barley
crop. Chickpeas and wheat concentrated in the west and center but in scattered
areas. The area of wheat crop according to image classification was 30494 ha which
accounted 8.97% of the studied area (Sweida governorate without Badia). The
degree of approach to the proportion of the Ministry of Agriculture was 95.19%.
The area of barley crop resulting from the classification process was 16705 ha,
which accounted 4.92% of the study area. While the area of barley according to the
statistics of Ministry of Agriculture was about 15933 ha. The area of chickpea crop
resulting from the classification process was 26063 ha which represented 7.67% of
the studied area. The results showed that the accuracy of the total classification was
82.4%, which allows satellite image to be used in calculating the area of strategic
crops and determine its locations and distribution.
