“…Aliphatic and indole glucosinolates in red and white radish, turnip, oilseed rape and arugula revealed as poor hosts for M. arenaria and M. incognita (Aydınlı and Mennan 2016) were determined in the study. According to the findings, the highest level of glucosinolates was quantified in radish containing glucoraphenin as the predominant glucosinolate followed by turnip containing glucobrassicanapin, progoitrin and gluconapin as the major 274 glucosinolates.…”

These species were selected among the poor hosts for M. arenaria and M. incognita according to Aydınlı and Mennan (2016).

“…In our previous study, we investigated 40 genotypes from 15 different Brassica species initially to assess their host suitability level of rootknot nematodes (M. arenaria and M. incognita) and 12 genotypes were found to be as poor host with low potential of nematode multiplication as cover crop for biofumigation (Aydınlı and Mennan 2016). The objective of our study was to determine the glucosinolates of the selected brassica species that were known as poor hosts for M. arenaria and M. incognita, thus to have an idea of the relation between glucosinolates and biofumigation effect of the Brassica plants.…”

Brassica species are sources of bioactive compounds with several biological properties including biocidal activity against various soil borne pathogens and pests such as parasitic nematodes. Isothiocyanates derived from corresponding glucosinolates are major bioactive compounds responsible for this activity. In this study, glucosinolate content of red and white radish (Raphanus sativus L.), oilseed rape (Brassica napus L.), turnip (Brassica rapa L.) and Arugula (Eruca sativa L.) that were previously assessed for their host suitability level of root-knot nematodes (Meloidogyne arenaria and Meloidogyne incognita) were determined to understand the relationship between glucosinolate content and host-suitability level of these crops. The highest glucosinolate content was in radish. Turnip revealed lower levels compared to radish. However, the lowest glucosinolate content was determined in arugula and oilseed rape. Together with previous findings demonstrating host-suitability levels, the effect of glucosinolates on biocidal potential of Brassicaceae plants to fight against root-knot nematodes were evaluated.Copy Right, IJAR, 2017,.

Introduction:-The incorporation of plants containing specific biologically active compounds into soil against soil-borne pests is a natural plant protection approach. The Brassicaceae plants synthesize glucosinolates (GSL) that are sources of bioactive compounds such as isothiocyanates with several biological properties including biocidal activity. They are classified as aliphatics, aromatics or indoles having different properties and functions. Genetic factors determine the glucosinolate profile of plants, therefore the glucosinolates produced by a plant may vary. Glucosinolate content, however, is under the influence of environmental factors as well as stress factors during the growth period as reviewed by Sarıkamış 2009. Although present in the entire plant, the amount of glucosinolates is variable at different plant parts and plant growth stages (Brown et al., 2003).Glucosinolates are hydrolyzed by endogenous myrosinases to produce an array of compounds including isothiocyanates, nitriles and indoles. Among these compounds isothiocyanates are associated with several biological activities including the suppression of soil borne pests (Lin et al., 2000). Benzyl isothiocyanate derived from the Corresponding Author:-G. Sarıkamıs. Address:-Ankara University, Faculty of Agriculture, Department of Horticulture, Ankara, Turkey. ISSN: 2320-5407Int. J. Adv. Res. 5(10), 271-278 272 hydrolysis of glucotropaeolin and 2-phenylethyl isothiocyanate has been shown to have high levels of antibacterial activity (Jang et al., 2010) and toxicity to several soil pathogens including nematodes and fungi (Jensen et al., 2010). Root-knot nematodes are plant parasitic nematodes that cause high losses in plants by reducing its quality and quantity. Chemical nematicides including soil fumigants have effectively controlled nematodes (Nyczepir and Thoma...

Host reaction of some cucumber cultivars to Meloidogyne arenaria and M. incognita Cultivation of resistant or poor hosts to root-knot nematodes provides significant advantages in nematode-infested areas. In this respect, it is important to know the reactions of the different varieties to the root nematodes. In this study, the host status of 15 cucumber cultivars (Cucumis sativus), which are widely used commercially, to M. arenaria and M. incognita was evaluated by a pot experiment in a greenhouse. Although nematode infection increased root weights of all cultivars compared to the controls, these increases were significant (P≤0.05) only in 1 cultivar (Toskono) and other 2 cultivars (Everest and Seyhan) for M. arenaria and M. incognita, respectively. These cultivars also had the highest formation of galls for related nematode species among all tested. All of the cucumber cultivars were susceptible to different levels of both nematode species, and the lowest gall index according to the 0-10 gall index were detected in Almino with 2.8 for M. arenaria and Venüs with 3.8 for M. incognita. The highest and the lowest reproduction factors on cultivars were 5.84 and 17.16 for M. arenaria and 8.28 and 17.84 for M. incognita, respectively. Nine cultivars showed different reaction at the significant level in terms of reproductive factor compared to the nematode species and 8 of them also differed based on the galling index.

Nematolojik açıdan tuzak bitki uygulamaları, topraktaki nematod populasyonunu baskılamak amacıyla uygulanabilecek bitki temelli stratejilerden biridir. Tuzaklama stratejilerinde, nematod ve konukçusu arasındaki parazitik ilişki kritik bir öneme sahiptir. Bir alanda tuzak bitkilerin kullanım şekli, tuzak bitki olarak kullanılan bitkinin özelliği ve bu bitkinin imha edilme zamanına bağlı olarak değişmekle beraber; genellikle ana ürün ile aynı zamanda tekli sıralar, çoklu sıralar veya düzensiz dağılım şeklinde ya da ana üründen önce yetiştirilme şeklinde olabilir. Her ne kadar, nematodlar için tuzak bitki olarak bilinen bitki sayısı sınırlı olsa da, nematodun konukçusu ile olan beslenme davranışı da dikkate alındığında, hassas bitkilerin bile tuzaklama amacıyla kullanılabilecek potansiyelde olması, bu uygulamanın bir mücadele stratejisi olarak kullanılabilme potansiyelini artırmaktadır. Özellikle, tuzak bitkilerin hassas bitkiler arasında kısa süreli yetiştirilmesiyle, üretim yapılan alandaki nematod populasyonunun etkili bir şekilde azaldığı ve kendinden sonra yetiştirilen bitkide, belirgin verim artışı sağlandığı bilinmektedir. Ayrıca, kimyasal kullanımının da azalmasına katkı sağlayan bu yaklaşımlar, hem ekonomik olarak daha karlı bir üretimin yapılmasını, hem de çevre ve insan sağlığı için güvenli ve sürdürülebilir bir üretimin gerçekleştirilebilmesini sağlamaktadır. Bu nedenle, kök-ur nematodları ile mücadelede tuzak bitkilerin kullanımının ele alındığı çalışmada, öncelikle kök-ur nematodunun biyolojisi hakkında özet bilgi verilerek, nematod biyolojisi ve tuzaklama stratejileri ile bağlantısı açıklanmaya çalışılmıştır. Tuzaklamanın 2 uygulama şekli olan; tuzak özelliğine sahip bitkilerin kullanıldığı uygulamalar ile hassas bitkilerin tuzak olarak kullanıldığı uygulamalar ve tuzaklama uygulamasını destekleyici stratejiler, günümüze değin yapılan örneklerle derlenerek özetlenmiştir.
