Combined effect of Pasteuriapenetrans and neem extract on the development of root-knot nematode in medicinal plants

Abstract

Medicinally important plant babchi (Psoralea coolifolia L.) is highly susceptible to root-knot nematode (Meloidogyne incognita) infection. Study was conducted to access the potential of Pasteuria penetrans and neem extract alone and in combination on Meloidogvne incognita. All treatments significantly reduced the nematode infection as compared to control. Infection was least when P. penetrans and neem extract applied in combmation. It gave maximum Increase in shoot weight, shoot length and reduction in the root weight. Minimum number of juveniles per root system was observed in case of combined application of P. penetrans and neem extract.
