The experiment was conducted at the field of Onion and Grape Research Station, Pimpalgaon Baswant, Nashik under Mahatma Phule Krishi Vidyapeeth, Rahuri during rabi 2019-20. The object was to evaluate the efficacy of newer molecules against thrips(Thrips tabaci L.) and mites(Tetranychus urticae Koch) of garlic. For this purpose, six insecticides treatments were applied and compared with untreated control. Among these treatments, first two chemicals in each treatment were insecticides against thrips and third one was acaricide applied against mites. In case of bio-efficacy studies, the treatments T? (spinetoram 11.7 % SC @ 60 ml a.i.ha1 followed by fipronil 80 % WG @ 60 g a.i. ha-1) and T? (acetamiprid 20 % SP@ 20 g a.i.ha1 followed by spinetoram 11.7 % SC @ 60 ml a.i. ha-1) were most effective for management of garlic thrips (Thrips tabaci L.).Similarly, for management of two spotted garlic mites (Tetranychus urticae Koch.), the treatment T? (spiromesifen 22.90 % SC @ 96 ml a.i. ha-1) and T? (hexythiazox 5.45 % EC @ 25 ml a.i. ha-1) were found effective. Over all, in bio-efficacy studies, it is suggested either treatment T? (spinetoram 11.7 % SC @ 60 ml a.i. ha-1followed by Fipronil 80 % WG @ 60 g a.i. ha-1 followed by hexythiazox 5.45 % EC @ 25 ml a.i. ha-1 ) or treatment T? (acetamiprid 20 % SP@ 20 g a.i. ha-1followed by spinetoram 11.7 % SC @ 60 ml a.i. ha-1 followed by spiromesifen 22.90 % SC @ 96 ml a.i. ha-1)for good management of garlic thrips and mites along with high yield and net returns per hectare along with good incremental cost benefit (ICBR) ratio (17.82 and 20.51 respectively)
