Studies on persistence of biorationals against diamondback moth, Plutella xylostella L

AM Parihar, DB Undirwade and RM Wadaskar

The present investigation was conducted to evaluate five different biorationals, viz., Beauveria bassiana (1.15% WP), Metarhizium anisopliae (1.15% WP), Bacillus thuringiensis (0.5% WP), Azadirachtin (300 ppm) and Spinosad (45 SC) against P. xylostella larvae at Department of Agricultural Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2015-16. F. The data on persistence toxicity study was recorded 1, 5, 10 and 14 days after the application of treatment at an interval of 24 hrs up to the adult emergence. Spinosad registered highest persistence toxicity whereas; Beauveria and Metarhizium revealed lower ability. PT values based trend of different treatments, on the basis of larval mortality was Spinosad (1085.0) > B. thuringiensis (612.5) > Azadirachtin (542.5) > M. anisopliae (466.7) and > B. bassiana (437.5), whereas, on the basis of adult emergence the descending order of persistence was Spinosad (1214.7) > B. thuringiensis (802.9) > B. bassiana (705.9) > Azadirachtin (679.4) > M. anisopliae (607.8).
