“…Incorporation of these materials into the soil may represent a possible solution to the problem of their disposal and in addition could result as an important resource of nitrogen, phosphorus, calcium and other elements as zinc, copper, magnesium essential to plant growth (Tester, 1990). Various mechanisms are involved in the suppressive action among which the development of nematode natural enemies and the release of toxic compounds were found to be the most relevant (Stirling, 1991;Abawi & Thurston, 1994;Oka et al, 2000). For plant-parasitic nematodes, the effectiveness of suppression varies depending from nematode species, type of amendment and amendment dose (Nico et al, 2004).…”

“…Although various organic amendments can have diverse effects on soil properties and nematode communities (Nahar et al, 2006;Hu & Qi, 2010), all amendments tend to increase availability of plant nutrients, microbial biomass and bacterivore and fungivore nematodes (Briar et al, 2007). Chicken manure is also known to be effective in the control of root knot nematodes (Akhtar, 1997;Lopez-Pérez et al, 2005;Oka et al, 2000;D'Addabbo et al, 2003) and the mode of action is thought to be based on the release of toxic levels of ammonium, although alterations in soil structure, the stimulation of antagonistic organisms, and the increase of plant tolerance also may play a role (Oka et al, 2000;Lopez-Pérez et al, 2005). Therefore, a pot experiment was carried out to compare the nematicidal and fertilizing effects of different amendments on organic melon.…”

The fertilizing and nematicidal effects of three organic amendments were evaluated in a pot experiment on melon plants infested by the root-knot nematode Meloidogyne incognita. A soil artificially infested with 4 eggs and juveniles/ ml soil of the nematode was amended with: a) virgin olive pomace (VOP); b) composted olive pomace (COP); c) chicken manure based fertilizer (CM) and d) chicken manure based fertilizer combined with the biological control agent Paecilomyces lilacinus strain 251, brand name BioAct WG (CMB). VOP was applied at doses of 11 (VOP-A), 22 (VOP-B) and 44 t/ha (VOP-C); COP at 4.5 (COP-A), 9 (COP-B) and 18 t/ha (COP-C); CM at 3 t/ha and CMB at 3 t/ha combined with 4 kg/ha of BioAct WG. Untreated soil was used as control. The treatments CM, CMB, VOP-B and COP-B were established on the basis of N requirement of melon plants (120 kg/ha) taking into account soil and amendments N availability. Two weeks later amendment application and nematode inoculation, the soil was poured in 4.8 l clay pots which were arranged in a greenhouse according to a randomized block design with ten replications for each treatment. A one-month old melon seedling (cv. Galia) was transplanted in each pot and organic farming management practices were used during the growing period. At the end of the experiment, 60 days after transplant, plants were uprooted and height, fresh and dry shoot and root weights were recorded. Root gall index, on the roots, caused by the nematode attack, was estimated according to a 0–5 scale. Final nematode population density and reproduction rate were also calculated for each pot. All data were subjected to statistical analysis of variance (ANOVA) and means compared according to Least Significant Difference’s Test. Nematode population and root infestation were significantly suppressed by the addition of all amendments, compared to untreated control. However, CM and CMB resulted in a total more suppressive effect and in a significantly higher plant growth in comparison to all the other treatments. A significant correlation was found between root gall index and eggs and juveniles/g root and final nematode population density. No signifycant correlations were found between nematological parameters or plant growth parameters and amendment doses.

SummaryThe root-knot nematode Meloidogyne arenaria was found in Greece infecting balm (Melissa officinalis L.) and grapevine (Vitis vinifera L.). The isolate from balm was M. arenaria while the one from grapevine was a mixture of M. arenaria and M. javanica (prevalent species). This is the first report of the M. arenaria species in the country in which identification was based on biochemical methods and its occurrence on balm is a new host record. Key words: esterase phenotypes; Melissa officinalis; Vitis viniferaRoot-knot nematodes (RKN), Meloidogyne spp., are among the most economically important nematodes in agriculture with a wide host range (Oka et al., 2000;Karssen & Moens, 2006). In Greece, RKN have been found in several areas and their identification was based on morphological and morphometric characters and/or differential host tests. Morphological identification of Meloidogyne species is a difficult task, even for qualified taxonomists with expertise in the genus, while esterase phenotypes of several RKN are species specific and can be used as reliable taxonomic characters (Esbenshade & Triantaphyllou, 1990;Pais & Abrantes, 1989). To date, the only records of Meloidogyne populations from Greece, in which biochemical and molecular methods were used for their identification, are referred to M. javanica (Treub) Chitwood and M. incognita (Kofoid and White) Chitwood found in vegetable crops (Tzortzakakis et al., 1999(Tzortzakakis et al., , 2005. In autumn 2004, galls of RKN were found in roots of grapevine (Vitis vinifera L.) and surrounding tomatoes and egg plants grown in a home yard in Crete (southern Greece). In summer 2005, some plants of a balm crop (Melissa officinalis L.) in Thrace (northern Greece) showed ……….. symptoms of stunting and wilting. The roots of the balm plants were examined and the presence of RKN galls was detected. Galled root samples of grapevine and balm plants were taken and egg masses were collected. The RKN isolates were bulked up by inoculating egg masses on to the susceptible tomato (Lycopersicon esculentum Mill.) cv ACE. Every two months the plants were uprooted and egg masses of each isolate were transferred to new plants. The plants were maintained in a controlled environment growth room with 16 h photoperiod at 23 -25 0 C.The identification of these RKN isolates was based on perineal patterns morphology and esterase phenotypes of females extracted from tomato infected roots (Hartmann & Sasser, 1985;Esbenshade & Triantaphyllou, 1985;Pais et al., 1986). The esterase phenotype designated as J3 and A2 were recognized in the isolate from grapevine and the phenotype A2 in the isolate from balm ( Fig. 1

“…Root-knot nematodes (RKNs), Meloidogyne spp., cause significant losses of yield and quality in many crops all over the world, and the annual global losses have been estimated as US$100 billion worldwide (Oka et al, 2000). There are four common species of RKN in the tropical and temperate areas: M. incognita, M. hapla, M. arenaria and M. javanica (Moens et al, 2009).…”

Baermann method, while that of M. incognita and M. hapla from 0.6 to 713 J2 equivalent (J2eq)/20 g soil and from 0.0 to 115 J2eq/20 g soil, respectively, with the real-time PCR method. The yield was determined by the sum of commercial sized eggplants harvested for 3 months of the cultivation period. The yield decreased in the plots with an initial population of RKNs more than 2 J2/20 g soil with the Baermann method. In real-time PCR, the yields were low in the plots with the sum of initial M. incognita and M. hapla more than 128 J2eq/20 g soil. The present study established a quantification method with real-time PCR for M. incognita and M. hapla in andosol and evaluated the relationship between the initial population of Meloidogyne spp. and the yield of eggplant.
