Other claims from this paper (8)

Observation No endemic entomopathogenic nematodes were detected in New York muck fields.
Intervention effect Spinosad caused nematode mortality.
Intervention effect Cyromazine caused some nematode mortality.
Intervention effect These insecticides did not affect nematode infectivity.
Intervention effect Nematodes reduced D. antiqua damage over two field seasons.
Intervention effect Nematodes increased end of season yield over two field seasons.
Recommendation The authors consider nematode application viable for D. antiqua reduction in conventional and organic systems.
Recommendation The authors conclude nematodes alongside other management tactics can boost yield and provide acceptable control.
