Field experiments were carried out during Kharif 2007 and 2008 at the Horticulture Research Station, Devihosur, Haveri, Karnataka to find out the bio-efficacy of Flubendiamide 24% +Thiacloprid 24% -48% SC against chilli thrips. Different dosages of Flubendiamide 24% + Thiacloprid 24% -48% SC viz., @ 36 + 36, 48 + 48 and 60 + 60 g a.i./ha, were evaluated along with comparative checks. Raised nursery seed beds were prepared with the variety Byadagi dabbi. Thirty five days old seedlings were transplanted to main field. Among different dosages, Flubendiamide 24% + Thiacloprid 24% -48% SC @ 48 + 48 g a.i./ha recorded least number of thrips and least leaf curl damage of 0.46 LCI/plant which was significantly superior to comparative checks and recommended insecticide, Profenofos 50 EC @ 500 g a.i./ha and equally good as that of its higher dosage. The dry chilli yield was also better in Flubendiamide 24% + Thiacloprid 24% -48% SC @ 48 + 48 g a.i./ha (7.18 q/ha), which was equally good to its higher dosage and significantly superior to comparative checks and standard check of Profenofos 50 EC @ 500 g a.i/ha (5.77 q/ha).
