1. Manejo de Meloidogyne exigua em seringueira com produtos biológicos e químicos
RESUMO Com a finalidade de se conhecer melhor sobre o manejo de Meloidogyne exigua na cultura da seringueira, foram testados em campo dois métodos de controle, o químico e o biológico, da Morte Descendente da Seringueira. Assim, neste trabalho, objetivou-se avaliar a resposta de seis tratamentos: T1 – Testemunha, T2 - Paecilomyces lilacinus + Trichoderm

2. Infestações de Meloidogyne exigua em clones asiáticos de seringueira no Mato Grosso, Brasil
RESUMO O cultivo de seringueira apresenta entre os problemas fitossanitários a incidência do nematoide das galhas, mais especificamente o Meloidogyne exigua raça 3, demonstrando relevante importância para a cultura, fato constatado na presente avaliação, pois levou ao abandono do plantio. Neste experimento foi avaliada a infestação de M. exigua em pl

3. Analysis of Infestation of Nematode Meloidogyne exigua in a Rubber Tree Plantation in the Triângulo Mineiro Region
ABSTRACT This study analyzed the use of the water balance, precipitation, temperature and NDVI (Normalized Difference Vegetation Index) to determine the optimum moment for evaluating infestation by the nematode Meloidogyne exigua in a rubber tree plantation by remote sensing. Nineteen sampling points were defined, divided into three areas, with high and low

4. 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.

5. ESTIRIL-LACTONAS DE Cryptocarya aschersoniana Mez. (Lauraceae Juss.) COM ATIVIDADE CONTRA Meloidogyne spp. E INTERAÇÃO IN SILICO COM PROVÁVEL FUMARASE DEMeloidogyne hapla
In a previous study, substances with nematicidal properties were detected in the bark of Cryptocarya aschersoniana. Continuing such study, the methanol extract from this plant underwent fractionation guided by in vitro assays with the plant-parasitic nematode Meloidogyne exigua. Two active compounds were isolated and identified by spectroscopic methods as (E

6. 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

7. Purification and identification of metabolites produced by Bacillus cereus and B. subtilis active against Meloidogyne exigua, and their in silico interaction with a putative phosphoribosyltransferase fromM. incognita
Com o objetivo de contribuir para o desenvolvimento de produtos para o controle de Meloidogyne exigua, as bactérias Bacillus cereus e B. subtilis foram cultivadas em meio líquido de cultura para produzirem metabólitos ativos contra este nematoide parasita de plantas. Os fracionamentos dos extratos em diclorometano dos meios de cultura produziram uracila,

8. 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

9. 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

10. Desenvolvimento e respostas fisiológicas de mudas de cafeeiro parasitado por Meloidogyne exigua e M. paranaensis / Development and physiological responses of seedlings of coffee parasitized by Meloidogyne exigua and M. paranaensis
The nematodes of the genus Meloidogyne are responsible for the largest losses in coffee crop. M. exigua is the most widespread species in coffee area and causes large losses, but M. paranaensis, the most aggressive species, can derail the coffee crop in infested areas. Under field conditions has been observed that the coffee is more tolerant to M. exigua par

12. O nematóide das galhas: o inimigo oculto dos cafezais.
Dentre as doenças que causam danos à cultura do café em Rondônia, o nematóide das galhas é uma das principais. As espécies que causam prejuízos são Meloidogyne exigua, M. javanica, M. hapla, M. incognita, M. paranaensis. Dessas, as espécies M. incognita, M. exigua e M. javanica são as mais comuns em Rondônia.
