ABSTRACT
The minimum larval incidence of H. armigera of 0.95 and 0.36 larva/m row length was recorded in rynaxypyr 20
SC at 3 and 7 days after spraying, respectively followed by flubendiamide 48 SC (1.47 & 0.78 larvae/m row length) and
emamectin benzoate 5 SG (1.55 & 1.49 larvae/m row length) as against conventional insecticide profenophos 50 EC
which recorded 2.09 and 1.49 larva/m row length. The treatment with rynaxypyr 20 SC was found significantly effective
in reducing the pod damage (3.5%) followed by flubendiamic 48 SC (4.8%) and emamectin benzoate 5 SG (6.05%) as
compared to profenophos (13.9%). The highest (2590 kg/ha) grain yeild was recorded in rynaxypyr 20 SC followed by
flubendiamide 48 SC (2354 kg/ha) and emamectin benzoate 5 SG (2292 kg/ha). However, the highest (1:19.22) ICBR
(Incremental cost benefit ratio) was recorded in flubendiamide 48 SC followed by rynaxypyr 20 SC (1:11.1), profenphos
50 EC (1:7.8), emamectin benzoate 5 SG (1:4.2) and lufenuron 5.4 EC (1:3.5).
Key words : Cicer arietinum, Heliothis armigera, Management.
