Control of root-knot nematode (Meloidogyne incognita) on tomato plants by using root extracts of plants.

Muhammad Zameer Kayani, Ghulam Sarwar, Sher Muhammad


Meloidogyne incognita eggs were exposed to root extracts of Melia azadirach Linn (Dharek), Azadirachta indica A. Jass (Neem), Ricinus communis Linn (Castor) and Datura alba Linn (Datura). Standard root extracts of Neem and Dharek exhibited 100% inhibition of egg hatching and larval mortality. Egg inhibition and larval mortality decreased with an increase in the dilution of the extracts. Similarly with an increase in exposure time, juvenile mortality was also increased.
