“…There are reports of the occurrence of M. incognita in hops in Iran ( Jamali et al, 2016 ), also presenting the typical symptom of root infestation. There have been reports of Meloidogyne javanica (Treub, 1885) Chitwood, 1949, causing damage to hops in Florida, USA and São Paulo, Brazil ( Brito et al 2018 ; Nascimento et al 2020 ). Root-knot ( Meloidogyne spp.)…”
In 2019, during a nematologic survey in Jaboticabal, Brazil, root-knot nematode
Meloidogyne incognita
parasitizing hops (
Humulus lupulus
) was identified with based on morphological characters of adults, esterase phenotypes (
n
= 16), and molecular analysis. Modified Koch’s postulates was carried out and after 90 days, the average total population recovered had different stages of development, with a reproductive factor (RF) of 4.81. This is the first report of
H. lupulus
as a host of
M. incognita
in the state of São Paulo and in Brazil.
