Abstract:

The root-knot nematode, Meloidogyne incognita is a key pest on tomato cultivation throughout the world. Eco-friendly technique for the management of M. incognita on tomato is still lacking. Hence, studies were conducted to test the nematicidal potency of leaf extracts of asparagus, white hibiscus, jasmine and Ixora plants against M. incognita under in vitro and pot culture. Under in vitro condition juvenile mortality rate was higher (49.4-90.2%) in asparagus treatment where as mortality rate was lower in Ixora treatment (8.2-35.4%). Pot culture experiment on the efficacy of plant extract on M. incognita revealed that the infection of root-knot nematode in terms of number of galls/plant was lower in asparagus leaf extract treatment. In other treatments, the number of galls varied from 33-57 / plant where as in control 100 galls/plant. Asparagus treated plants were taller with long root system. It is concluded that leaf extracts of asparagus is having high nematotoxic potential against M. incognita which can be recommended to tomato growers for root-knot nematode control after testing under field situations.
