EFFECT OF OLIVE POMACE SOIL AMENDMENT ON MELOIDOGYNE INCOGNITA

T. D'Addabbo, N. Sasanelli

Abstract


The nematicidal effect of 0.5, 1, 2 and 5% w/w exhausted olive pomace soil amendment after 2, 4 and 8 weeks of decomposition in the soil was tested on Meloidogyne incognita in vitro and in the glasshouse. Juvenile emergence was reduced by 30% in leachates from soil amended with 5% olive pomace, with no difference among various degradation periods. Reproduction of M. incognita in the amended soil was significantly suppressed at all amendment rates, decreasing by 50% at the highest pomace rate.
