ABSTRACT

In Jhansi Baruasagar area is a repository of commercially important medicinal plants including ginger (Zingiber officinale Zingiberaceae). Ginger is a crucial natural medicine that has been utilized to ameliorate numerous ailments, such as colds, nausea, arthritis, migraines, and hypertension. The investigation was undertaken on ginger crops infected by Root-knot nematodes, Meliodogyne incognita. Diseased plants displayed impaired shoot growth and presence of galls on roots and the deposition of numerous gelatinous egg masses. The severe invasion led to the generation of multiple galls, yellow leaves, reduced rhizome size and weight, root rot and gradually plant succumbed to death. The acid fuchsin stain confirmed the presence of M. incognita inside the root cells. Infective Juvenile stage (J2), eggs, and females with eggs were observed. The nematode caused histological changes in root tissue in the form of giant cells with multiple nuclei. This is the first report of M. incognita infecting ginger in Jhansi.
