ABSTRACT
Aqueous extract of six weed species including Argemone mexicana, Sonchus asper, Abutilon indicum, Xanthium strumarium, Solanum nigrum and Mavastrum coromandelianum were tested for their activity towards egg hatching and juvenile mortality of Meloidogyne javanica, the root-knot nematode. Aqueous extract of A. mexicana was most lethal to M. javanica juveniles and caused significant inhibition in egg hatching. In general, with an increase in extract concentration and duration for which the juveniles were exposed, mortality increased markedly. Results demonstrated that A. mexicana could be exploited for the suppression of root-knot disease in crops.
