Ecofriendly management of Meloidogyne incognita on Hyoscyamus niger

Ecofriendly approaches such as organic soil application in the form of neem oil, seed cake and dried leaf powder in combination with few plants viz. Adhotoda vasica Nees, Mentha arvensis L. and Murraya koengii L. caused significant reduction in the population of root knot nematode, Meloidogyne incognita on black henbane (Hyoscyamus niger L.). The most effective application for reducing nematode population and subsequently favoured various growth parameters was obtained in neem cake and M. koengii treated soil. It was followed by neem cake and A. vasica and neem cake and M. arvensis combinations. These different treatments also inhibited root galling, whereas, higher doses of neem cake alone showed some phytotoxic effect on the growth of the host plant.
