Abstract

Management of eriophyid mite Aceria cajani, as transmitting agent of sterility mosaic disease of pigeonpea.

Abstract

The bioefficacy of five concentrations of Magister 10 EC (fenazaquin 10 EC) and five other acaricides/insectoacaricides (dimethoate, endosulfan, abamectin, dicofol and Mitex-S (micronized sulfur)) was evaluated in the laboratory against Aceria cajani, the vector of the viral pathogen causing sterility mosaic disease. Out of the chemicals tested, Magister 10 EC applied at 0.015, 0.020 and 0.025% and Mitex-S applied at 0.05% proved to be promising, causing significantly higher mortality of Aceria cajani and remained at par with that of the most popular acaricide, dicofol applied at 0.05 and 0.06%. This finding provides alternative options for the farmers to choose this acaricide in place of dicofol to avoid the development of acaricidal resistance in the mite due to use of the same chemical over the years.
