Root vegetables have been present in our country from the earliest times. Paleobotanical sources indicate the presence of seeds of plants of the family Apiaceae (carrots or parsnips) from the 6th millennium BC from the Belo Brdo site. The greatest damage to these plants is caused by nematodes of the genus Meloidogyne, whose larvae burrow into the roots and transform into adult organisms inside the tissue, causing tissue deformation, tumor formation and can completely jeopardize vegetable yields. The populations of M. hapla were found on carrots and parsnips from the vicinity of Leskovac and Belgrade, respectively and they are morphologically characterized. The larval morphometric data show no significant differences between the populations however, M. hapla from parsnips shows more variations in the female perineal pattern, which is a characteristic of the species.

“…In addition, RKNs are commonly found in kiwifruit orchards around the world. There are eight RKN species including Meloidogyne incognita (Kofoid & White, 1919), Meloidogyne arenaria (Neal, 1889), Meloidogyne hapla (Chitwood, 1949), Meloidogyne javanica (Treub, 1885), Meloidogyne luci (Carneiro et al, 2014) (as M. ethiopica) Meloidogyne ethiopica (Wheathead, 1968), Meloidogyne actinidiae (Li & Yu, 1991) and Meloidogyne aberrans (Tao et al, 2017) (Tylenchida: Meloidogynidae) reported in kiwifruit producing areas around the world (Vovlas & Roca, 1976;Haygood et al, 1990;Le & Yu, 1991;Philippi et al, 1996;Nicotra et al, 2003;Corneiro et al, 2004;Corneiro et al, 2007;Ma et al, 2007;Ploetz, 2009;Tao et al, 2017;Shokoohi & Mashela, 2020). Eighty-six weed species in 32 families have been found in kiwifruit orchards in Ordu Province (Yonat & Kolören, 2017).…”

In this investigation, the species of root-knot nematodes (RKNs) infesting weeds in kiwifruit orchards were investigated in the Ordu Province, Türkiye. A survey was conducted in 2018 and roots of weeds with RKN infestations were found in kiwifruit orchards. The infested weed samples were collected from 27 kiwifruit fruit orchards located in the Ordu Province. Identification of RKNs was performed using the molecular method based on mitochondrial DNA (mtDNA). The mtDNA region between the cytochrome oxidase II and the large subunit ribosomal RNA was amplified using two pairs of primers TRNAH/MRH106 and MORF/MTHIS. Species-specific primers previously described were used to confirm Meloidogyne species as the last step. Meloidogyne incognita (Kofoid & White, 1919), Meloidogyne arenaria (Neal, 1889) and Meloidogyne hapla (Chitwood, 1949) (Tylenchida: Meloidogynidae) were identified from fifteen weed species (2 unidentified) in eight families. Meloidogyne incognita was the most frequent species with 74.1% of the samples infested, followed by M. hapla at 22.2% and M. arenaria at 3.7%. In this study found Erigeron canadensis L. (Asterales: Asteraceae), Mercurialis annua L. (Malpighiales: Euphorbiaceae), Oxalis pes-caprae L. (Oxalidales: Oxalidaceae), Clinopodium nepeta (L.) Kuntze (Lamiales: Lamiaceae), Fumaria officinalis L. (Ranunculales: Papaveraceae) and Lycopus spp. (Lamiales: Lamiaceae) to be previously unrecorded hosts of M. incognita and Sigesbeckia orientalis L. (Asterales: Asteraceae) and Lythrum spp. (Myrtales: Lythraceae) a host of M. hapla.

“…The genus Meloidogyne represents over 100 species 5 , with over 3000 host plant species. Meloidogyne is the most dangerous plant-parasitic nematode, which causes yield loss of the crops 6 . The biological control agents, such as antagonistic bacteria, are up-and-coming to reduce plant diseases 7 .…”

Background and Objective: Pseudomonas fluorescens is an essential group of growth-promoting bacteria that can directly or indirectly improve plant growth. Several studies showed they could limit or suppress root-knot nematode. In this study, the effect of ten Iranian isolates of P. fluorescens (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10) was assessed on eggplant growth parameters and the management of the root-knot nematode (Meloidogyne incognita) under greenhouse condition. Materials and Methods: The M. incognita was reared in tomato seedlings. The bacteria inoculum was reared in tryptic soy broth. Hydrogen cyanide and protease were assessed on the plate (9 cm diameter) include King B and Skim Milk Agar (SMA), respectively, in a dark situation. The greenhouse experiment was done to evaluate the effect of P. fluorescens isolates on M. incognita and plant parameters. The data was analyzed statistically using SAS software. Results: Eggplant seedlings were inoculated with ten P. fluorescens isolates in the presence or absence of M. incognita. The result displayed P. fluorescens isolate M 1 significantly improved the plant growth parameters and reduced the nematode reproductive factors for M. incognita associated with eggplant. In vitro results showed that isolates M 1 , M 3 , M 6 and M 7 caused significantly (p<0.05) more nematode mortality than the other isolates and the control. Conclusion: Based on the present study result, P. fluorescens isolate M 1 seems to be the best applicant for improving the growth and biological control of M. incognita in eggplant crops under greenhouse situations.
