Nematoides fitoparasitas em seringais do Estado de São Paulo

Abstract: A seringueira, Hevea brasiliensis, é nativa da região Amazônica e a espécie mais importante do gênero. O estado de São Paulo é o maior produtor nacional com uma área plantada de cerca de 90.000 hectares. Por muito tempo as mudas de seringueira foram produzidas diretamente no solo ou em sacolas plásticas com substrato a base de terra de barranco sem tratamento, o que propiciou a disseminação de pragas e patógenos do sistema radicular. O objetivo do presente estudo foi determinar a incidência de fitonematoides e… Show more

“…Nematode sampling confirmed field observations, occurring in greater number in Area 1, with approximately 2,437 nematodes per 150 cm 3 soil and 3,780 nematodes per gram of roots. This plantation has greater infestation than that reported by Wilcken et al (2015) in plantations in the state of São Paulo, which was 320 nematodes per 250 ml soil and 256 nematodes per 10 g roots. According to those authors, 87.5% of the soil samples containing M. exigua presented population levels between 8 and 100 nematodes, while the other 12.5% was between 100 and 320 nematodes per 250 ml soil; also, 94.7% of the root samples presented 16 to 100 nematodes, while 5.3% presented 100 to 256 nematodes per 10 g roots.…”

“…Os gêneros Meloidogyne e Pratylenchus são considerados os mais importantes para a cultura da seringueira; entretanto, outros nematoides também são encontrados habitando seringais (WILCKEN et al, 2015). No gênero Pratylenchus, a espécie P.…”

“…Quase todas as espécies de nematoides de galha são especialmente importantes em regiões de agricultura tropicais e subtropicais (LE, 2020). Um grande problema que vem afligindo os heveicultores no Brasil tem sido a rápida disseminação do nematoide Meloidogyne exigua, principalmente por meio da produção de mudas de seringueira (BERNARDO et al, 2003;PAES-TAKAHASHI et al, 2015;PEZZONI FILHO, 2014;WILCKEN et al, 2015).…”
