“…of common bean were classified as moderately susceptible hosts to the nematode infection but another thirteen of tested cultivars were regarded as least susceptible hosts. These results are in agreement with those of O'Bannon & Santo (1982); Oteifa & Elgindi (1982); Mullin et al, (1991 a,b); Omwega & Roberts (1992); Chen & Roberts (2003) and Sharma et al, (2006).…”

Twenty seven leguminous cultivars were tested for their host response to Meloidogyne javanica. The nematode species succeeded in developing and multiplying on almost all the tested crops. According to rating scale based on nematode reproduction, Lencoln and Victory cultivars of pea were considered as highly susceptible hosts with (R f) values 36.5 and 25.68 folds, respectively. While Maser-1 cultivar of broad bean and Bronco, Exira, Giza-6, Polista and Savana cultivars of common bean were classified as moderately susceptible hosts to nematode infection with (R f) values ranged between 5.27 and 14.21 folds. Thirteen other tested cultivars were found least susceptible with (R f) values ranged between 1.13 and 4.86 folds. On the other hand, M. javanica failed to reproduce and multiple on Giza-2 and Giza-30 of fenugreek and Giza-1 and Giza-2 of lupine which were ranked as highly resistant hosts with (R f) values 0.12, 0.33, 0.19 and 0.42 folds, respectively, whereas Giza-843 and Giza-51 of broad bean and lentil were regarded as resistant hosts to nematode infection with (R f) values 0.59 and 0.80 folds, respectively.

“…Inconsistent findings for glasshouse and field experiments, however, included that 'DM 6.2i RR' was susceptible to field populations of M. incognita at Bethlehem, Brits and Middelburg. This is not unexpected since such anomalies have been reported from other studies for M. incognita-and/or M. javanica-resistant genotypes (Fourie et al 2006;Sharma et al 2006). Also, the Brazilian 'BRSGO Raissa' was classified as susceptible to M. javanica (Embrapa 2011), while Teixeira et al (2017) reported it as resistant.…”

The host status of South African adapted, genetically modified (GM) glyphosate-tolerant soybean genotypes to root-knot (field and glasshouse) and lesion (field) nematodes were assessed. Analyses of root and soil samples of 29 genotypes (collected from seven production areas during the 2014/15 season) enabled the identification of nine plant-parasitic nematode genera and 10 species. Predominant endoparasitic genera in root samples were Meloidogyne (Meloidogyne incognita and M. javanica) and Pratylenchus (Pratylenchus brachyurus, P. zeae and P. teres). Rotylenchulus parvus was the predominant semi-endoparasite in soil, followed by Scutellonema brachyurus and Helicotylenchus sp. Only ‘PAN 1583 R’ and ‘PAN 1521 R’ maintained less than 10% of the Meloidogyne spp. densities present in roots of the most susceptible genotype, while all genotypes were susceptible to the Pratylenchus spp. The host status of 36 soybean genotypes to M. incognita infection, evaluated in two follow-up glasshouse experiments terminated 56 days after inoculation of ca. 1000 M. incognita eggs and second-stage juveniles (J2) per seedling, varied substantially for final population density (Pf), reproduction factor (Rf) and relative percentage susceptibility (%S). Only ‘PRF-GCI7’ and the resistant reference ‘LS 5995’ had Rfs < 1 for both experiments, despite higher minimum and maximum temperatures recorded for the second experiment. Continuous evaluation of soybean genotypes for their host status to predominant nematode pests and their use to reduce densities of such species in producer’s fields are crucial to enable sustainable crop production, and contribute towards food provision and security.

“…The noticeable occurrence of additional plant parasitic nematodes in rice growing systems could be due to changes in agricultural practices, particularly in use of new rice varieties and the practice of rice intercropping with other crops, mainly vegetables, gown for fresh market. Indeed, with the increasing scarcity of water and rainfall, most growers are often shifting from monoculture rice system to intensive and continuous intercropping with several other crops among which are vegetables known to be hosts of plant parasitic nematodes (Sharma et al, 2006;Anwar et al, 2007;Singh and Khurma, 2007;Anwar et al, 2013), particularly in lowland ecosystem initially dedicated to rice cultivation. In Togo, rice is grown mostly in lowland ecosystem where continuous production without interruption may result in an increase in nematode population diversity and densities, as documented in this study.…”

Rice is the second most important cereal in Togo. Among constraints that affect rice production, plant parasitic nematodes are of great importance. The objective of this study was to determine the distribution, abundance and frequency of plant nematodes in different agroecological zones of Togo. A total of 50 composite soil and root samples (25 each) were taken from 25 fields (5 per zone) randomly selected from the five agroecological zones. Nematodes were extracted from 100 ml soil and 1g fresh root samples using the Hermann techniques. Nematodes were then fixed and mounted on slide and identified to genus level using identification keys. The survey documented twelve plant-parasitic nematode genera among which ten, (Hirschmanniella spp., Meloidogyne spp., Xiphinema spp., Scutellonema spp., Helicotylenchus spp., Heterodera spp., Criconema spp., Pratylenchus spp., Trichodorus spp. and Tylenchid spp.), were recorded from lowland, two (Helicotylenchus and Scutellonema) from upland and five (Dolichodorus spp., Helicotylenchus spp., Tylenchorhynchus spp., Scutellonema spp. and Xiphinema spp.), from flooded ecosystem. Hirschmanniella spp., Meloidogyne spp and Helicotylenchus spp. were the most frequent and abundant plant-parasitic nematode genera recorded from more than 71% of the samples. Helicotylenchus spp., Hirschmanniella spp., Meloidogyne spp. and Scutellonema spp., were recorded in both soil and root samples while Pratylenchus spp., Heterodera spp. and Tylenchorhynchus spp., were found to be associated to root and Trichodorus spp., Tylenchid spp., Xiphinema spp., Criconema spp. and Dolichodorus spp., were recorded from soil samples only. The high diversity of nematode genera recorded in the survey is attributed to the rice ecosystem, which is mostly characterized by lowland ecosystem with intensive cropping. This study established the evidence that nematodes could be important constraints for rice production, suggesting further research focusing on their damage potential and development of effective rice nematode management strategy for sustainable rice production in Togo.
