We studied in this research the systemic activity of fungicide carbendazim in cucumber plants (Hybrid F1 Milton). The soil was treated with fungicide with concentrations of 0.25 - 0.5 - 1.0 - 2.5 g active ingredient per kg of soil and the month-old plants was sprayed (three true leaves) with the recommended concentration 0.25 active ingredient per liter of water, half and double of concentration. Bioassay method was used to detection the systemic activity of fungicide by putting the plant parts in direct contact with sensitive fungus spores within petri dishes that containing PDA. It has been detected the presence of carbendazim in the root , cotyledonary leaves and first real leaf after 20 days from treatment the soil for all concentrations, as it was observed the fungicide persistence in plants after forty days. In the spraying treatment, It has been detected the presence of carbendazim after one day for all concentrations and for the recommended and double concentration only after five, ten and twenty days of spraying.

Research summary
تتناول هذه الدراسة النشاط الجهازي للمبيد الفطري كربندازيم في نباتات الخيار وتأثيره على نمو النباتات. تم تطبيق المبيد على التربة بتراكيز مختلفة (0.25 - 0.5 - 1.0 - 2.5 غ مادة فعالة لكل كغ تربة) وعلى النباتات بعمر شهر (ثلاث أوراق حقيقية) بتراكيز مختلفة من الرش الورقي. استخدمت الطريقة الحيوية للكشف عن النشاط الجهازي للمبيد من خلال وضع الأجزاء النباتية بتماس مباشر مع أبواغ فطر حساس للمبيد على بيئة PDA ضمن أطباق بتري. أظهرت النتائج وجود المبيد في الجذر والأوراق القلقية والورقة الحقيقية الأولى بعد 20 يوماً من معاملة التربة، واستمر وجوده بعد 40 يوماً. في معاملة الرش الورقي، تم الكشف عن المبيد بعد يوم واحد من الرش في جميع التراكيز، واستمر وجوده في التركيز المنصوح به وضعفه بعد 5 و10 و20 يوماً من الرش. كما أظهرت الدراسة تأثيرات سلبية للمبيد على نمو النباتات، حيث لوحظ انخفاض في طول ووزن النباتات مع زيادة تركيز المبيد ومدة التجربة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير المبيد الفطري كربندازيم على نباتات الخيار، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين مجموعة أكبر من التراكيز للتحقق من تأثيرات المبيد بشكل أكثر تفصيلاً. ثانياً، لم يتم التطرق بشكل كافٍ إلى التأثيرات البيئية المحتملة لاستخدام هذا المبيد على التربة والمياه الجوفية. ثالثاً، كان من الممكن توسيع نطاق الدراسة ليشمل أنواعاً أخرى من النباتات لمعرفة ما إذا كانت النتائج متشابهة. وأخيراً، كان من الممكن تقديم توصيات أكثر وضوحاً للمزارعين حول كيفية استخدام المبيد بشكل آمن وفعال.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو معرفة مدى مثابرة المبيد كربندازيم ضمن الأنسجة النباتية والتربة، وتحديد تأثيره على نمو نباتات الخيار.

  2. ما هي الطريقة المستخدمة للكشف عن النشاط الجهازي للمبيد؟

    استخدمت الطريقة الحيوية للكشف عن النشاط الجهازي للمبيد، وذلك بوضع الأجزاء النباتية بتماس مباشر مع أبواغ فطر حساس للمبيد على بيئة PDA ضمن أطباق بتري.

  3. ما هي النتائج الرئيسية التي توصلت إليها الدراسة؟

    أظهرت النتائج وجود المبيد في الجذر والأوراق القلقية والورقة الحقيقية الأولى بعد 20 يوماً من معاملة التربة، واستمر وجوده بعد 40 يوماً. كما أظهرت تأثيرات سلبية على نمو النباتات بزيادة تركيز المبيد ومدة التجربة.

  4. ما هي التوصيات التي قدمتها الدراسة للمزارعين؟

    نصحت الدراسة بعدم استخدام التراكيز العالية من المبيد على الشتول في بداية عمرها لتجنب التأثيرات السلبية على نمو النباتات.

This study aimed at studying the effect of using three species of bacteria (PGPR) Azotobacter chroococcum Bacillus megaterium and Frateuria aurantia in three inoculation manner ( seeds, shoots & seed+shoots) on suppressed the effect of Cucumber mo saic virus (CMV) on tomato plants (pots), Some growth parameters such as plant height, number of leaves on plant, foliage fresh weight, root fresh weight were observed after 60 days. The experiment carried out in 2016 in a greenhouse in Tartus.
Ten medicinal plants were chosen from various plants in Syria which used as spices or cooked and Syria traditional medicine. Their names Rosemary, Damask rose, Chamomile, Sumac, Silver linden, Black cumin, Thyme, Mint, Laurel and lemon balm. Mois ture, yield of extraction, total phenolic content (TPC) and antioxidant activities of methanol, ethanol, acetone and aqueous extracts of medicinal plants were investigated. The TPC were measured by Folin-Ciocalteu method, and the antioxidant activity was assessed by the scavenging activity towards 2, 2′-diphenyl- 1-picryl hydrazyl (DPPH)-radical.
This study was conducted in the village of Almetrkyah located in the southern coastal plain of Lattakia city during 2014. In order to study the effect of Cucumber mosaic virus on growth and development of two varieties of peppers, hybrid ESTAR F1 H (sweet pepper) and Demer(spicy pepper). This study included eight treatments, four treatments for each variety. Plants were mechanically inoculated in three different stages, preflowering bloom, flowering andpost-flowering stages each beside its non-inoculated control. The result should that, the appearance of Cucumber mosaic virus symptoms on infected sweet hybrid, was within four days before its appearance on inoculated spicy variety,symptoms were leaf crinkle, leaf deformation, yellow patches and plant stunting. Inoculated plants showed reduction in number of leaves, number of branches and yield. Plants in pre flowering bloom stage were more effected by virus infection in both varieties. Meannumber of leaves per plant of ESTAR F1 H hybrid were 130 in pre flowering bloom stage compared with 170 leaf/plant in the control treatment. Mean number of branches per plant of ESTAR F1 H hybrid were 43,4 branch/plant in pre flowering bloom stage compared with 56,7branch/plant in the control treatment. Total pepper production per plant was 700,8g in infected plants in preflowering bloom stage compared with 1267,5g/plant in ESTAR F1 H hybrid control. Results of Demer variety take the same results of ESTAR F1 H hybrid. The effect of virus infection on pepper plants were reduced when inoculation were done during flowering stage and post-flowering stage, differences were significant between inoculated plants in both varieties.
The investigation aimed to survey the thistle of genus Carduus spp in its habitat in Alswayda and Damascus countryside and associated plants, by visiting these areas through flowering seasons of Carduus spp during 2013- 2015.
Laboratory experiments were conducted to study the effect of the aqueou extract of the vegetative parts of the Euphorbia paralias at different concentrations (2%,4%,8%) in seed germination and seeding growth of the Lepidium sativum, Lactuca sativa and Portulaca oleracea. The results indicated increase in germination ratio of Portulaca oleracea. up to 7%. while the effect of the extract was not evident in the germination of the seeds of Lepidium sativum, and decreased the germination ratio of Lactuca sativa seeds by 35.9% at the concentration of 8%.In contrast, the extracts stimulated the length of the stalks of Portulaca oleracea , Lepidium sativum and Lactuca sativa plants at all used concentrations used. The highest rate of stimulated stalks legnth of Lepidium sativum at 2% was 58.2%. inhibitory effect of water extract observed for root length of Portulaca oleracea and Lactuca sativa plants at 2% , and stimulation effect pour Lepidium sativum, The effect became evident at the concentrations of 4% and 8% for the three plants. The most sensitive and affected plants was Portulaca oleracea, where the length of the root decreased by 53.38% at the concentration of 4% and by 72% at the concentration of 8% ,while the length of the root Lepidium sativum and Lactuca sativa decreased by 25.82% and 34.95% was decreased for 4% and 8%respectively. The results suggested that this weed may affect seedling growth, due to inhibitory or stimulatory effect of Allelochemicals , which present in water extract of this weed . and may used as potential Bioherbicide after further experiments.
