Sathyan T, Dhanya MK, Preethy TT, Aswathy TS and Murugan M

A field experiment was conducted at the experimental farm of Cardamom Research Station, Pampadumpara, Idukki District, Kerala during 2016-17 to evaluate the bio-efficacy of new molecules against thrips, Scirtothrips dorsalis on rose. The results revealed that significantly lowest population of thrips per three buds was recorded in fipronil 5 SC @ 0.15%, imidacloprid 17.8 SL @ 0.02%, tolfenpyrad 15 EC @ 0.1% and diafenthiuron 50 WP @ 0.12%. The insecticides dimethoate 30 EC @ 0.15%, acetamiprid 20 SP @ 0.02% and thiacloprid 21.7 SC @ 0.1% were also proven to be efficient in managing thrips population of rose as compared to thiamethoxam 25 WG @ 0.02%, chlorpyriphos 20 EC @ 0.25% and chlorfenapyr 10 SC @ 0.1%. The maximum per cent reduction over untreated check was obtained from fipronil 5 SC (82.35%), imidacloprid 17.8 SL (78.55%), tolfenpyrad 15 EC (73.52%) and diafenthiuron 50 WP (72.95%).
