“…The most damaging plant-parasitic nematodes are considered to be the root-knot nematodes (RKNs), Meloidogyne sp. ( Almohithef et al, 2018 ), which are responsible for losses in vegetable crops throughout the world and determine the common use of chemical pesticides ( Sikandar et al, 2020 ). In Spain, RKNs can be found in all horticulture areas ( Archidona-Yuste et al, 2018 ), causing yield losses in essential vegetable crops, such as cucumber (85%), tomato (59%), zucchini (40%), watermelon 36%, and lettuce (29%) ( Gullino et al, 2019 ).…”

This work focuses on investigating plant-parasitic nematodes that affect greenhouse vegetables. The study took place in the Rostov region (Russian Federation) between May 2019 and May 2020 and involved 180 samples of soil and roots of 30 different vegetables in the families Cucurbitaceae (6), Solanaceae (8), Umbelliferae (8), Lamiaceae (4) and Allioideae (4) from 20 intensive farming locations. In this study, 11 nematode genera were detected. The most common genus was Meloidogyne, followed by Helicotylenchus, Pratylenchus, and Scutellonema. The highest Meloidogyne densities were detected in cucumbers, green peppers, carrots, eggplants, basil, and celery. Onions were not infected with Meloidogyne at all. Plant diseases caused by Pratylenchus, Scutellonema and Helicotylenchus were present in 29.7%, 51.5% and 81.6% of all crops examined, respectively. Xiphinema were found exclusively in carrots and celery, while Ditylenchus were only present in tomatoes and carrots (for each, the prevalence was 2.1%). The relative abundance of Meloidogyne, Helicotylenchus, and Pratylenchus was 58.3%, 10.4%, and 2.1%, respectively. As regards other genera, the relative abundance was less than 1%. The results show that soil properties are as important for the abundance, distribution and structure of the plant-parasitic nematode communities as the host plant. Findings may be helpful in improving the vegetable pest controls.

“…They may exist as free-living nematodes, plant parasitic nematodes (phytoparasitic nematodes) and animal parasitic nematodes (zooparasitic nematodes). These parasitic species have been reported to cause a tremendous destruction to a wide range of organisms, including animals, microorganisms and plants, such as common vegetables, fruits and trees [29] . As a result, there have been significant damages to public health, economy and environment worldwide.…”

New hetaryl fragment tagged 1H-1,2,4-triazole derivatives 7a-l were designed and synthesized via Suzuki coupling between the bromo derivatives 4-6, which were used as key intermediates for the synthesis of our targets and the appropriate boronic acid. The structures of the newly synthesized compounds were unambiguously confirmed through physico-chemical analysis (1H, 13C NMR and mass spectra). Six synthesized 1,2,4-triazole derivatives were selected to evaluate the potential nematocidal effect and to analyze their structure-activity relationships. Nematocidal activity of the compounds at (50, 100, 200, 300, 400 and 500 µM) was tested against Bursaphelenchus xylophilus nematode wherein the best activity was recorded for compound 7e (52.1% ± 1.8 mortality at 100 µM). The highest mortality rates of 88% and 55% were observed for 7e and 7h, respectively at 500 μM after exposure for 6 h. The molecular docking of compounds 7e, 7h and 7g has been studied and its results revealed that the newly designed hetaryl fragment tagged 1H-1,2,4-triazole derivatives bind to the hydrophobic pocket and polar contact with high affinity.

“…They concluded the positive effects of grafting on plant growth, productivity, and water use efficiency, which support this strategy as a useful tool for improving water stress tolerance in greenhouses. Almohithef et al [ 35 ] presented a survey of plant-parasitic nematode genera associated with certain greenhouse vegetable crops in Saudi Arabia. It is known that the plant-parasitic nematodes are serious pathogens attacking vegetable crops that are grown in domestic greenhouses.…”

“…According to recent statistics of the World Bank, Saudi Arabia has only 1.8% of its overall space as arable lands, like many countries in the middle east and Arab region [ 22 ]. The total area and production of fruit-bearing vegetables under greenhouse farming in Saudi Arabia reach 3019 ha, and 252,824 ton in 2016, respectively [ 35 ]. Cucumber is the second, where Tomato is the first, main greenhouse fruits-bearing vegetables grown in Saudi Arabia, with a cultivated area of 885 ha and a total production of 79,650 tons, respectively [ 35 , 36 ].…”

Food security has become an increasingly important challenge for all countries globally, particularly as the world population continues to grow and arable lands are diminishing due to urbanization. Water scarcity and lack of labor add extra negative influence on traditional agriculture and food production. The problem is getting worse in countries with arid lands and harsh climate, which exacerbates the food gap in these countries. Therefore, smart and practical solutions to promote cultivation and combat food production challenges are highly needed. As a controllable environment, greenhouses are the perfect environment to improve crops’ production and quality in harsh climate regions. Monitoring and controlling greenhouse microclimate is a real problem where growers have to deal with various parameters to ensure the optimal growth of crops. This paper shows our research in which we established a multi-tier cloud-based Internet of Things (IoT) platform to enhance the greenhouse microclimate. As a case study, we applied the IoT platform on cucumber cultivation in a soilless medium inside a commercial-sized greenhouse. The established platform connected all sensors, controllers, and actuators placed in the greenhouse to provide long-distance communication to monitor, control, and manage the greenhouse. The implemented platform increased the cucumber yield and enhanced its quality. Moreover, the platform improved water use efficiency and decreased consumption of electrical energy. Based on the positive impact on water use efficiency and enhancement on cucumber fruit yield and quality, the established platform seems quite suitable for the soilless greenhouse cultivation in arid regions.
