Pigeonpea (Cajanus cajan L. Millsp.) is the second most important pulse crop grown in India. Root-knot nematodes are the most important nematode pests, distributed in all the pigeonpea growing areas, causing considerable losses. Its infestation causes stunted growth and sometimes death of plants takes place due to fungal association with nematodes. Yield losses have been estimated to the tune of 5-35% depending on the nematode population present in the field. For growing pigeonpea successfully, it becomes inevitable to manage the nematode in infested fields. Some nematicides have been found effective to control the nematodes (Jaiswal et al. 1987, Singh and Singh 1998). However, their high doses and cost compel to find out alternatives to the chemical control of nematodes. Neem products have been found effective for the control of insect pests and nematodes in different crops (Akhtar 2000, Bajpai and Sehgal 2000). In the present studies, different neem based products were used as seed treatment for managing the root-knot nematode, Meloidogyne javanica in pigeonpea.
