Pathogenicity and life cycle of Meloidogyne incognita on sugarbeet in India

摘要

In India, the acreage of sugar beet has increased considerably in recent years and root-knot nematodes (Meloidogyne spp.) have frequently been reported to cause damage to this crop (Singh and Misra, 1970, 1974; Mathur and Prasad, 1978). The most prevalent species found on sugarbeet in India is M. incognita (Kofoid et White) Chitw. on which investigations on the life cycle and pathogenic potential have been made and are reported here.
