Abstract

Despite the important role of coffee production in the economy of Espirito Santo, the second largest coffee producing state in Brazil, productivity is still below the Brazilian average. One of the factors that explain this low productivity is the presence of nematodes of the genus Meloidogyne. Contaminated seedlings are an important and efficient agent for disseminating nematodes. According to normative instruction no. 35 (IN 35), of 11/29/2012 of the Ministry of Agriculture, Livestock and Supply (MAPA), the presence of Meloidogyne spp. in a single plant among a field-lot of seedlings condemns it, and the plants that compose that lot should be destroyed. In Espirito Santo, no evaluation has been carried out in nurseries covering the entire State for phytonematode detection. Therefore, the objective of this work was to carry out a nematological survey in nurseries to guide the nurserymen in relation to fulfilling IN 35 of MAPA, in addition to guiding them regarding the phytosanitary care during the production of their seedlings. The nurseries were evaluated in 19 municipalities located in both the north and the south of Espírito Santo. There were Meloidogyne spp. in evaluated samples.

Highlights

Coffee farming plays a socioeconomic role of great importance for the State of Espírito Santo
Barros et al (2014) made a nematological survey in coffee fields in the State of Espírito Santo regarding the presence of Meloidogyne spp. in Coffea spp. and reported the presence of M. exigua, M. incognita and M. paranaensis, these latter two species being very aggressive to the coffee tree
Whereas no evaluation has been performed in nurseries covering the entire state of Espirito Santo regarding the presence of phytonematodes, this study aimed to carry out a nematological survey in nurseries, with the following goals: i) to ascertain the possible presence of phytonematodes in nurseries; ii) to guide the nurserymen about fulfilling instruction no. 35 (IN 35) of MAPA; iii) to alert the nurserymen about the phytosanitary care they should employ during the production of their seedlings and, in this way, prevent the dissemination of phytonematodes in coffee farming areas in the State

Summary

Introduction

Coffee farming plays a socioeconomic role of great importance for the State of Espírito Santo. The state continues to be the country’s second largest coffee producer, productivity in Espírito Santo has historically always been below the Brazilian average, which is around 24 sc/ha (CONAB, 2017). The main species of nematodes associated with coffee tree belong to the genus Meloidogyne, with emphasis on M. incognita, M. paranaensis, M. exigua, and M. coffeicola (Barbosa, 2004; Contarato et al, 2014; Sera et al, 2017). Barros et al (2014) made a nematological survey in coffee fields in the State of Espírito Santo regarding the presence of Meloidogyne spp. in Coffea spp. and reported the presence of M. exigua, M. incognita and M. paranaensis, these latter two species being very aggressive to the coffee tree
