Bio-efficacy of Ecomite against Tetranychus cinnabarinus Boisduval in Okra

A new molecule, Ecomite, the plant origin acaricide was tested for its efficacy against okra mite during rabi 2006–2007 season. After three days of application, among all the test chemicals significantly reduced mite population in Ecomite @ 3.0 ml/lit (4.29 mites/leaf) which was on par with its lower dose i.e., @ 2.0 l/lit (6.98 mites/leaf) and other test chemicals viz., milbemectin 1 EC @ 1.0 ml (5.99 mites/leaf), fenazaquin 10 EC @ 2.0 ml/lit (8.56 mites/leaf) and spiromecifen 24 SC @ 0.65 ml/lit (12.29 mites/leaf). Observations taken at 7 and 10 days after application revealed similar trend. However, the fruit yield registered by Ecomite @ 2.0 ml/loan of water was 33.66 q/ha but did not differed significantly with Ecomite @ 3.0 ml/lit. treatment. This showed that new acaricide, Ecomite @ 2.0 ml/l of water, found to be effective and optimum dosage for managing the mites on okra which protected the spider mite up to 10 days after application.
