Novel frond injection method using cartap hydrochloride for the management of Opisina arenosella

Abstract

The present study was carried out at farmer’s field at Halebudanur village in Mandya district in Karnataka, India during 2017–18. Frond injection method, a novel approach of insecticide administration into the coconut palm was applied using an eco-friendly and animal origin insecticide cartap hydrochloride (50% SP) against Opisina arenosella Walker. The results on absorption showed that all the dilutions of cartap hydrochloride (50% SP) injected to fronds were absorbed completely within 24 h and recorded 100 % larval mortality, 7 days after imposing injection and found superior over control. This method showed quicker and accurate absorption of insecticides into the coconut palm and did not cause any secondary infection of pathogen or mechanical injury to the frond tissues and can be useful on coconut palms.
