Abstract:

Evaluation of newer acaricide Tafethion against San Jose scale Quadraspidiotus perniciosus Comstock and European red mite Panonychus ulmi Koch was evaluated for bio efficacy, phytotoxicity and effect on natural enemies in apple orchards at two locations in Kashmir during the year 2014 and 2015.  Ethion was used as standard check for conducting the experiment. Both the acaricides were sprayed during dormant and summer seasons to suppress different stages of the pests. The acaricides were sprayed with the concentrations viz., 1.25,1.0 and 0.75 % in both the seasons. All the concentrations significantly reduced the insect pest populations over the standard check. Highest percent mortality of 68.21 and 77.41 were recorded against San Jose scale and 77.13 and 82.49 against European red mite at a concentration of 1.25 % during dormant and summer seasons respectively. None of the phytotoxicity effects were seen on the apple trees. Amblyseius, Stethorus punctum and Coccinellids were the key predators found feeding on European red mite and San Jose scale respectively. Maximum cumulative mean mortality of natural enemies was found to be 36.79 % at 1.25 % concentration of Tafethion. The findings of the study revealed that spraying of the acaricide results in considerable reduction in the rate of infestation of European red mite and San Jose scale on apple trees at both the locations.
