T. D'Addabbo, N. Sasanelli

Abstract


Soil amendments with grape pomace at 5, 10, 20, 30, 40 and 50 g/kg soil dosages, alone or combined with 100, 200 and 400 mg N/kg soil of urea or 250, 500, 750 and 1000 mg N/kg soil of calcium cyanamide, were tested for their suppressive effect on Meloidogyne incognita on tomato in three different glass house experiments. Grape pomace significantly reduced reproduction and galling of M. incognita at all the tested dosages. The nematicidal effect was increased by the addition of 400 mg N/Kg soil of urea and reduced by combination with calcium cyanamide.
