Abstract:

Diafenthiuron, a novel insecticide with different mode of action of energy production inhibition and IGR activity was found to be effective against Conogethes punctiferalis in field trials conducted and concluded that 800ga.i./ha concentration can be recommended. Supervised field experiments that conducted during January 2014 - April 2014 at Nedukandam, Idukki district, Kerala with the cardamom cultivars, Njellani (Green gold) revealed that diafenthiuron 50 WP (NS) as foliar application at 1600, 800 and 400 g a.i. ha-1 effected 77.07, 79.23 and 72.71 per cent reduction in capsule damage, and 77.86, 77.63 and 67.19 per cent reduction in shoot damage respectively, thirty days after three applications. No visual phytotoxic symptoms viz., leaf injury, wilting, vein clearing, necrosis, epinasty and hyponasty were observed with diafenthiuron 50 WP (NS) at 1600, 800 and 400 g. a.i. ha-1.


Keywords: Diafenthiuron 50WP, Njellani gold, C. punctiferalis, IGR, Phytotoxic symptoms.
