Report of the Texas peanut root-knot nematode, Meloidogyne haplanaria (Tylenchida: Meloidogynidae) from American pitcher plants (Sarracenia sp.) in California

During February and May 2021, several potted American pitcher plants (Sarracenia sp.) with roots galls induced by root-knot nematodes were collected from a botanical garden in Los Angeles County, California. Based on the analysis of several molecular markers, the root-knot nematode extracted from the galled roots was identified as the Texas peanut root-knot nematode M. haplanaria (Eisenback et al., 2003) in the Nematology Laboratory, Plant Pest Diagnostics Center, California Department of Food

Nematicide efficacy at managing Meloidogyne arenaria and non-target effects on free-living nematodes in peanut production

Peanut (Arachis hypogaea) is an important crop in the United States with 757,000 ha planted in 2018, worth $1.15 billion (NASS-USDA, 2019a, b). Much of the production is concentrated in the Southeast where Meloidogyne arenaria (peanut root-knot nematode (PRKN)) can significantly reduce yields with suppression approaching 50% observed in field research (Rodriguez-Kabana and Robertson, 1987; Rodriguez-Kabana et al., 1994a, 1994b). Damage thresholds for this nematode are 1 egg/100 cm3, so any
