Acaricide Etoxazole 10 SC was tested against European red mite Panonychus ulmi (ERM) and two-spotted spider mite Tetranychus ulmi (TSSM) for bio efficacy, phytotoxicity and effect on natural enemies in apple orchards at two locations in Kashmir during the year 2018 and 2019. Propargite was used as standard check for conducting the experiment. Both the acaricides were sprayed during the successive summer seasons to suppress different stages of the pests. Etoxazole was sprayed at the concentrations of 0.2, 0.5, 0.8 and 1.1 ml water-1. All the concentrations significantly reduced the populations of both the mite pests over control. Highest cumulative mean percent mortality of 70.62 and 70.0 were recorded at the concentration of 1.1 ml water-1 against European red mite at locations of Nagbal and Chandpora respectively. Similarly highest cumulative mean percent mortality of 69.11 and 69.17 were recorded at the concentration of 1.1 ml water-1 against two-spotted spider mite at locations of Nagbal and Chandpora respectively. Propargite @ 2 ml water-1 exhibited cumulative mean percent mortality of 72.80 and 73.34 against European red mite and 72.32 and 71.58 against two spotted spider mite at locations of Nagbal and Chandpora respectively. None of the phytotoxic effect was seen on the apple trees at each of the concentration tested. Natural enemies like Amblyseius and Coccinellids were the key predators found feeding on European red mite and two-spotted mite respectively. Among the various concentrations of Etoxazole, maximum cumulative mean percent mortality of natural enemies was found at the concentration of 1.1 ml water-1.
