1. IAC 125 RN - A dwarf coffee cultivar resistant to leaf rust and root-knot nematode
Abstract IAC 125 RN was derived from a cross between the coffee cultivar Villa Sarchí and the Hibrido de Timor CIFC 832/2. The coffee trees are short and resistant to races 1 and 2 of the nematode Meloidogyne exigua and to all races of coffee rust, Hemileia vastatrix, present in Brazil. Brazil.

2. Resistance of sweet potato clones to meloidogyne incognita races 1 and 3
The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm

3. 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

4. Inheritance of resistance to soybean cyst nematode races 3 and 14 in soybean RIL and F2 populations
The objective of this work was to evaluate the soybean inheritance of resistance to cyst nematode races 3 and 14. The following populations where evaluated: one population of recombinant inbred lines (RILs) [Hartwig (resistant) x Y23 (susceptible line)] for races 3, 14 and 9; one population of families F2:3 [M-SOY 8001 (resistant) x MB/BR 46 - Conquista (sus

5. Risk analysis of climate change on coffee nematodes and leaf miner in Brazil.
The objective of this work was to assess the potential impact of climate change on the spatial distribution of coffee nematodes (races of Meloidogyne incognita) and leaf miner (Leucoptera coffeella), using a Geographic Information System. Assessment of the impacts of climate change on pest infestations and disease epidemics in crops is needed as a basis for

6. Quebra de resistencia da CV. Hartwig por populacao de campo do nematoide de cisto da soja (Heterodera glycines).
Em fevereiro de 1997, como parte de um monitoramento de racas do nematoide de cisto da soja (NCS) no Brasil, foi coletada uma populacao do nematoide em Sorriso (MT), identificada como raca 4, mas que foi capaz de se reproduzir na cv. Hartwig. Como esta cultivar sempre mostrou resistencia a todas as racas de Heterodera glycines, o presente trabalho objetivou

7. Utilização de matéria orgânica no controle de nematóide das galhas em alface sob cultivo protegido
This research was carried out aiming to evaluate the effect of organic manure in the control of root-knot nematodes in lettuce cv. Verônica. Organic cattle and chicken manure were evaluated; they are both used for vegetable production in the region. The experiment was carried out at Estação Experimental de Biologia, University of Brasilia, from July to No

8. Caracterização de tipo e raça de populações do nematóide de cisto da soja detectadas no município de Jataí/GO e proximidades por hospedeiros diferenciadores / Characterization of type and race of cyst nematode populations of the soybean detected in the council of Jataí/GO and close by differential hosts
The soybean is the most important oleaginous in production under extensive cultivation in Brazil occupying the second position of world production. Alongside the expansion of soybeans culture in Brazil, there was also an increase in plant health problems, including that of the soybean cyst nematode, (NCS), Heterodera glycines Ichinohe, 1952. The classificati

9. Levantamento de fitonematóides nas culturas de soja e milho no município de Jataí-Go / Detection of phytonematodes on soybean and corn cultures from county, Jataí, Goiás, Brazil
Population surveys of plant parasite nematodes are an important tool for the evaluation of their presence and losses caused by these organisms in many crops. The county of Jataí is considered as an important maize and soybean producer. Soybean was introduced in the county in the 80s and, up to now, a significant increase in planted area and yield has been o

11. Estratégias para seleção de linhagens experimentais de soja para tolerância à ferrugem e associações com outras doenças / Strategies for selection of soybean lines to rust tolerance and associations with other diseases
Soybean rust (Phakopsora pachyrhizi Sydow and Sydow) was first recorded in Brazil during the 2000/01 season and, even today, represents an important challenge to soybean breeding. The cultivars and lines initially identified as resistant had their resistance breakdown on the 2002/03 season, probably by the occurrence of new races of the pathogen. Consequentl

12. IdentificaÃÃo de raÃas do nematÃide de cisto da soja [Heterodera glycines (Ichinohe)] a partir de populaÃÃes de campo e isolados monocÃsticos e resistÃncia de cultivares comerciais à raÃa 3 / Race identification of the soybean cyst nematode (SCN) Heterodera glycines (Ichinohe) from field populations and monocystic isolates and resistance of commercial cultivars to race 3
O nematÃide de cisto à um dos principais patÃgenos da cultura da soja a nÃvel mundial. No Brasil, este nematÃide encontra-se disseminado em praticamente todas as regiÃes produtoras de soja, sendo responsÃvel por perdas de produtividade variÃveis, dependendo do nÃvel de infestaÃÃo a campo. No ParanÃ, esta espÃcie encontra-se amplamente distribuÃ
