Abstract: cinnabarinus in Rose” were carried out in the experimental farm, Department of Horticulture as well as in the Department of Entomology, Assam Agricultural University, Jorhat during 2012 and 2013. Carmine red spider mite, Tetranychus cinnabarinus boisduval was identified as the phytophagous mite in rose infesting the crop throughout the year. Evaluation of acaricides viz., profenofos 50EC (250g a.i./ha) and spiromesifen 240 SL (80g a.i./ha) and botanicals viz., bionol (10ml/l), pestoneem (3ml/l and 5ml/l) and eliminix (0.2%, 0.3% and 0.4%) were found effective in controlling the rose plants, against the carmine red spider mite, T. cinnaberinus, a maximum of 89.44% and 97.63% reduction was observed by the treatment Spiromesifen 240 SL after the 7th day of 1st and 2nd spraying of treatments during 2012-2013 which was at par with profenofos 50 EC (250g a.i./ha), eliminix (0.4%) and pestoneem (5ml/l). On the other hand, bionol (10ml/l) showed the lowest result in reduction of mites which was 40.83% and 46.63% after the 7th day of 1st and 2nd spraying of treatments during 2012 -2013, respectively. While other treatments were at par in controlling the mite population.
