The retention in the soil of nematocides toxic to golden nematode

, : The retention in the soil of nematocides toxic to golden nematode. Phytopathology. 49: 9, 540

Harrison describes a method for the detection of lethal concentrations of nematicides in soils after injection, using potato-root eelworm cysts. In tests at 70 degrees F. with D-D applied at 45 U.S. gal. per acre lethal concentrations were not present in the soil 72 hours after application. With ethylene dibromide (W-85) at 35 U.S. gal. per acre at 80 degrees F. lethal concentrations were not present 96 hours after treatment. J. E.
