Abstract: An experiment was conducted to test the efficacy of botanicals against pulse beetle in stored green gram at the laboratory of AICRP on PHET and Seed Technology Research Unit (STRU), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS) during the month of June to January in the year 2016-17. Eight treatments including untreated control, comprising of clove powder (3g/kg grain), tulasi leaf powder (3g/kg), black pepper powder (3g/kg), Acorus calamus rhizome powder (10g/kg), sesame oil (5ml/kg), soybean oil (5ml/kg), and castor oil (5ml/kg) were used against adult pulse beetle, Callosobruchus chinensis in stored green gram seed. Botanically treated seeds are taken into the 250 ml plastic vial and into which 5 pairs of newly emerged adult pulse beetles were released to record the percent seed germination at monthly interval for the six month of storage period. Higher rate of percent seed germination recorded in all the botanically treated seeds over untreated control. The order of per cent seed germination, i.e. maximum per cent seed germination was recorded in the seed treated with Acorus calamus rhizome powder (94.00%) followed by black pepper powder (93.00%), clove powder (92.00%), castor oil (89.00%), sesame oil (87.00%), soybean oil (86.00%), tulasi leaf powder (82.00%) and untreated control (79.00%).
