1. Selection of genotypes of peach rootstock resistant to Meloidogyne incognita
ABSTRACT The aim of this study was to evaluate the genotypes developed by the Peach Breeding Program at the Federal University of Viçosa, as regards to resistance to M. incognita. Six rootstocks genotypes propagated by cuttings (713-07, 713-13, 913-3, 913-6, 913-11 and 913-17) and two rootstocks propagated by seeds (‘Okinawa’ and hybrid between scion cu

2. Reaction of wild solanaceae species to Meloidogyne incognita
ABSTRACT The quest for resistance sources against Meloidogyne incognita as a control measure is essential in tomato. Thus, this study aimed to evaluate the reaction of six species of wild solanaceae to M. incognita. The species of wild solanaceae studied were Solanum capsicoides, S. asperolanatum, S. americanum, S. viarum, S. palinacanthum and Nicandra phy

3. Phytochemical management of root knot nematode (Meloidogyne incognita) kofoid and white chitwood by Artemisia spp. in tomato (Lycopersicon esculentum L.)
Resumo Experimentos in vitro e de triagem foram conduzidos para investigar a eficácia de treze constituintes fitoquímicos de Artemisia elegantissimia e A. incisa no nematóide de galhas, Meloidogyne incognita em tomateiro (Lycopersicon esculentum L.) cv. Rio Grande. Um controle positivo (carbofuran) e controle negativo (H2O) também foram utilizados para c

4. Supplanting resistance of the Mi gene by root-knot nematode in industrial tomato in the Cerrado in Goiás State of Brazil
RESUMO: Problemas causados pelos nematoides-das-galhas, pertencentes ao gênero Meloidogyne podem ser controlados com a introdução de genes de resistência em cultivares comerciais de tomateiro. No entanto, plantas do híbrido ‘Heinz 9992’ adequadas ao processamento industrial, portadoras do gene Mi, foram encontradas com suas raízes severamente infe

5. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

6. Reaction of wild Solanaceae rootstocks to the parasitism of (Meloidogyne javanica)
RESUMO A produção intensiva de hortaliças em ambiente protegido pode aumentar a quantidade de inóculo de patógenos habitantes do solo, a exemplo dos nematoides das galhas. Dessa forma, objetivou-se avaliar o potencial de solanáceas como porta-enxertos resistentes ao nematoide Meloidogyne javanica como alternativa à enxertia em tomateiro. O experimento

7. Biofumigation Studies by Using Raphanus sativus and Eruca sativa as a Winter Cycle Crops to Control Root-knot Nematodes
ABSTRACT An experiment was conducted to search the efficacy of radish (Raphanus sativus) and arugula (Eruca sativa) for the control of Meloidogyne arenaria in the commercial tomato growing greenhouse. R. sativus and E. sativa were used as winter cycle crops and lettuce as a susceptible crop and 4 months after sowing, host level of the treatment plants was ev

8. Host status of progenies of yellow passion fruit to Meloidogyne incognita race 2
Abstract The host status of eighteen progenies (CRP 01-12 to CRP 16-12, CRP 19-12 and CRP 20-12) and two cultivars (FB 200 Yellow Master and FB 300 Araguari) of yellow passion fruit to Meloidogyne incognita race 2 was evaluated in a greenhouse experiment. The height and the biomass of the plants, besides the numbers of galls, eggs and second-stage juveniles

9. Effects of silicon on the penetration and reproduction events of Meloidogyne exigua on coffee roots
Considering that the root-knot nematode Meloidogyne exigua has caused great yield losses to coffee production in Brazil, this study aimed to determine whether the penetration and the reproduction events of this nematode on the roots of plants from two coffee cultivars with different levels of basal resistance to this nematode could be affected by silicon (Si

10. Use of the arbuscular mycorrhizal fungus Glomus intraradices as biological control agent of the nematode Nacobbus aberrans parasitizing tomato
The plant-parasitic nematode Nacobbus aberrans is an endoparasite that induces gall formation in the roots and causes severe losses to diverse crops. Some populations of this nematode show preference for certain hosts, revealing the existence of "races/groups" with different behaviour and making nematode management difficult. A possible biological control al

11. Volatile organic compounds for the control of Meloidogyne exigua in Coffea arabica
Meloidogyne exigua is a plant-parasitic nematode that causes great losses to coffee farmers. Thus, to contribute to the development of new products to control this parasite, the present work studied the effect of volatile organic compounds (VOC) on the nematode and coffee plants (Coffea arabica), since these compounds are known to be used in plant defense ag

12. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C
