Other claims from this paper (6)
- Intervention effect Urea at 200-1000 mg N/kg soil reduced plant parasitic nematode populations.
- Intervention effect Adding HW to urea retained its activity against nematodes.
- Intervention effect Adding HW to urea reduced or eliminated soybean phytotoxicity at 200-800 mg urea-N/kg soil.
- Intervention effect HW alone at 2-32 g/kg soil reduced nematode numbers depending on species and rate.
- Observation HW alone failed to eliminate all plant parasitic nematodes.
- Intervention effect HW plus urea at 400 mg N/kg soil was nematicidal at every tested HW rate.
