The studies were conducted for the two seasons i.e., Zaid and Kharif to determine the seasonal incidence and management of Tetranychus urticae Koch on Okra, Abelmoschus esculentus (L.) Moench during 2015 at SKUAST-Jammu, Chatha, Jammu. The two season data of mites’ population on okra showed that T. urticae was found damaging and remain active on the okra crop and attained two peaks i.e., in 18th standard week and in in 25th SW, respectively. The increase in temperature coupled with decrease in relative humidity from March 2015 to June 2015 favoured the increase of T. urticae Koch. The pooled data on bio-efficacy of certain acaricides and botanicals against okra mite was recordedafter two spray (1st and 2nd spray revealed that Abamectin was found to be the best treatment in reducing the mites population (74.64 per cent) on okra followed by Diafenthiuron (68.02 per cent) and Fenazaquin (60.43. per cent). Among the biopesticides, pongamia oil gave 46.32 per cent reduction followed by neem oil application.
