“…M. paranaensis is widely spread in Coffea arabica and C. canephora coffee growing areas in Brazil and other Latin American countries (Barros et al, 2011;Barros et al, 2014;Villain et al, 2013). The alarming rise in the occurrence of this nematode in Minas Gerais State (Castro et al, 2003;Castro et al, 2008;Salgado et al, 2015), the largest C. arabica-producing state in Brazil, requires management practices to ensure the sustainability of coffee production in these areas.…”

Meloidogyne paranaensis is responsible for considerable losses in coffee production. Because of the distribution of this species in the main Coffea arabica producing regions, there is a need for management practices to ensure the sustainability of coffee production. In this work, we evaluated the agronomic performance of resistant clones of the Conilon coffee cultivar Vitoria Incaper 8142 in areas infested by M. paranaensis in the west region of Minas Gerais, Brazil. Clones 2V, 3V, and 6V presented the lowest number of nematodes per gram of roots and were considered resistant to M. paranaensis. All other clones were considered tolerant to this nematode, and one had good vegetative growth but allowed nematode reproduction. Clones of Vitoria Incaper 8142 of C. canephora represent an alternative to coffee production in areas infested by M. paranaensis including areas traditionally cultivated with C. arabica.

Nematodes are a serious issue for coffee cultivation in Brazil. Because root infection by nematodes induces spectral variation in leaves and defines a unique spatial configuration in the cultivation field, the aim of this study was to use biophysical parameters and remote sensing data to discriminate and map healthy, moderately infected, and severely infected coffee plants. An experimental area in southern Minas Gerais State, in which the occurrence of nematodes was certified, was selected, and biophysical and spectral measurements of the leaves were made. Hyperspectral data were also used in a band simulation of the RapidEye sensor to identify the most sensitive spectral ranges for pathogen discrimination in coffee plants. These bands, plus a normalized difference vegetation index image, were used for a multispectral classification of healthy and nematode-infected areas. None of the biophysical parameters efficiently discriminated the leaves of healthy and infected plants, but the band simulation indicated that red, red edge, and near infrared spectral ranges were complementary to the discrimination of healthy coffee plants and the two levels of infection. The multispectral classification defined the spatial distribution of healthy, moderately infected, and severely infected coffee plants, with an overall accuracy of 78% and Kappa coefficient of 0.71. Consideringthe degree of uncertainty and high cost involved in conventional detection of soil parasites, thelevels of accuracy achieved were adequate.

“…However, the presence of R. reniformes juveniles above 20 specimens per sample was observed in some cases. The reniform nematode (R. reniformes) is frequently associated to coffee roots (CASTRO et al, 2008;BARROS et al, 2014). However, Kubo et al, (2009) demonstrated that eight coffee cultivars inoculated with a population of R. reniformes did not perform as suitable hosts for this nematode.…”

“…In Central America this species is also harmful (VILLAIN; HERNÁNDEZ; ANZUETO, 2008), while in Brazil reports of coffee crops being anti-economic due to the incidence of this species are unusual (MOURA, PEDROSA, PRADO, 2002). The reniform nematode, Rotylenchulus reniformis, is also a frequently reported species in Brazilian coffee crops (BARROS et al, 2014;CASTRO et al, 2008), however, without any references about its effect.…”

Understanding the mechanisms of plant-parasitic nematodes (PPN) dispersion is vital to improve control strategies aiming to restrict dissemination of these plant parasites. In the present work, we evaluated the presence of PPN in Arabic coffee (Coffea arabica) seedlings produced in commercial nurseries in Minas Gerais, state, Brazil. A total of 2830 samples obtained from 318 coffee nurseries, in 84 counties within the South and Zona da Mata regions in Minas Gerais, Brazil and representing more than 62 million coffee seedlings, were analyzed. Meloidogyne spp. was identified in 11 samples from four counties. Pratylenchus spp. and Rotylenchulus reniformis were detected in 281 and 47 samples, respectively. According to the Regulatory Instruction N° 35 from the Ministry of Agriculture, Livestock and Food Supply (MAPA), in Brazil, coffee seedlings infected by Meloidogyne spp. are prohibited for commercialization and/or planting. However, such restrictions do not apply to other PPN. Therefore, seedlings sold in Minas Gerais may constitute sources of dissemination for root-lesion nematodes (Pratylenchus spp.) and the reniform nematode (R. reniformis).
