A present experiment was carried out to determine the Efficacy of different treatments for the management of mites on roses under polyhouse condition, were carried out during Oct 2011-Nov 2012 at Satpuda Botanical Garden, College of Agriculture, Nagpur. The experiment was laid out in randomized block design with eleven treatments and three replications. The result revealed that Propargite 0.1% gave best control for management of mite and recorded 82.37 per cent reduction on the basis of cumulative mean reduction of nymphal population at different intervals viz., 24hours, 7 days and 15 days after spraying followed by Acetamiprid 0.005% and Dimethoate 0.03% could reduced mites population to the extent of 79.39 and 77.63 per cent respectively and they were at parwith each other. The biopesticides viz., V. lacanii 10⁸ conidia ml-1, recorded reduction 58.60% of nymphal population and bioagent Chrysoperla carnea recorded reduction of mites up to the extent of 51.48 per cent. Among botanicals Nimbicidin 1500 ppm recorded the maximum population reduction of mites to the extent of 63.69 per cent. The treatment acetamiprid 0.005% was most effective with highest yield of 34 number of cut flowers/plot. The treatment dimethoate 0.03% was the next best treatment recording 31 numbers of cut flowers/plot. Followed by propargite 0.1% recording 29 numbers of cut flowers/plot. Dimethoate 0.03% was recorded highest ICBR (141.21) indicating most economically viable treatment followed by treatment acetamiprid 0.005% (101.42), Verticillium lacanii 10⁸ conidia ml-1 (58.44), Beauveria bassiana 10⁸ conidia ml-1 (49.30), nimbicidin0.15% (49.30), propargite 0.1% (37.88).
