EFFECT OF MELOIDOGYNE INCOGNITA AND HETERODERA SACCHARI SINGLY AND COMBINED ON THE GROWTH OF SUGARCANE

Abstract

The effect of a root-knot nematode, Meloidogyne incognita, and the sugarcane cyst nematode, Heterodera sacchari, on the growth of sugarcane (Saccharum officinarum L.) cv. Co 396 was investigated in a screenhouse. H. sacchari alone significantly reduced shoot weight and caused severe root necrosis. The effect of M. incognita was similar to that of H. sacchari. In concomitant infections with H. sacchari and M. incognita shoot and root weights of plants were significantly reduced; other symptoms were severe necrosis and galling of the roots.
