Bioefficacy studies of various insecticides against painted bug on Indian mustard [Brassica juncea (L.)
Czern & Coss.] during 2013-14 and 2014-15 at CCS Haryana Agricultural University, Hisar, revealed that
seed treatment with imidacloprid 600 FS @ 5 ml/kg seed (mean per cent reduction over control 84.4%) was
most effective in managing painted bug population at initial stage of crop and it was found on par with
thiamethoxam 35 FS @ 5 ml/kg seed (mean per cent reduction over control 82.80%). Among the insecticides
applied as foliar spray, imidacloprid 17.8 SL (78.3%) and thimethoxam 25 G (76.2%) found to be most
effective, while dimethoate 30 EC (62.35%), profenophos 50 EC (63.76%), malathion 50 EC (63.3%),
chlorpyriphos 20 EC (60.3%) and quinalphos 20 EC (60.2%) were found moderately effective. The treatment
with nimbecidine was found least effective but superior over control (47.9%) against the painted bug. Based
on the economic returns imidacloprid 17.8 SL, imidacloprid 600 FS and thimethoxam 25 G were adjudged as
best treatments for the effective management of painted bug.
