Bio-efficacy and dissipation of flubendiamide against shoot and fruit borer (Earias vittella Fab.) of okra

Deepak S, Narasa Reddy, Gaikwad SM and Shashibhushan V

The bio-efficacy of selected insecticides viz., bifenthrin 10 EC at 80 g a. i. ha-1, fipronil 5 SC at 500 g a. i. ha-1, flubendiamide 480 SC at 60 g a. i. ha-1, quinalphos 25 EC at 350 g a. i. ha-1, profenofos 50 EC at 400 g a. i. ha-1 and beta-cyfluthrin 25 SC at 18.75 g a.i. ha-1 against shoot and fruit borer (Earias vittella Fab.) of okra was studied in the field conditions at Student’s Farm of Agricultural College, Hyderabad during 2012. All the insecticidal treatments were superior over control after second spray where, Flubendiamide at 60 g a. i. ha-1 recorded lowest fruit borer infestation of 14.40 per cent on number basis and 15.90 per cent on weight basis. Further, dissipation pattern of Flubendiamide at 60 g a. i. ha-1 was studied by collecting 500 g of okra fruits from the field on zero (1 hr), one, three, five, seven and 10 and 15 days after second spray and analysed at laboratory of AINP on pesticide residues, Hyderabad. An initial deposit Flubendiamide was recorded to be 1.49 mg kg-1 dissipated to below detectable level on 10th day. The half life was 1.83 days with waiting period for safe harvest of okra fruit was 4.19 days.
