Abstract

Aqueous extracts of leaves of botanicals i.e. Argemone maxicana, Azadirachta indica, Calotropis procera, Datura inoxia, Delonix regia, Parthenium hysterophorous, Moringa oteifera, Saraca asoka and Withania sominifera plants were tested against root-knot nematode, Meloidogyne incognita under in-vitro trials. Undiluted crude leaf extracts of A. maxicana, A. indica and P. hysterophorous exhibited 78, 62 and 70 larve inhibition from eggs and 100, 100 and 60% mortality (out of hatched juveniles), respectively whereas Purpureocillium lilacinum (check) exhibited 79% inhibition of egg hatch and 31% mortality. Another in-vitro trial on mortality of tested nematode was observed up to 72 h with a revival test for 24 h. After revival 100% mortality was recorded with A. indica followed by
