Economic of different botanicals used for management of pulse beetle

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), castor oil (5ml/kg) were used against adult pulse beetle, Callosobruchus chinensis on green gram seed. All the botanicals recorded minimum percent seed infestation and percent seed weight loss than the untreated control over the six months of storage period. Among all the treatments Acorus calamus rhizome powder @10 g/kg seed and Black pepper powder @ 3g/kg seed was found significantly superior over the rest of treatments in respect to recording minimum percent seed infestation and seed weight loss. However, while taking the avoidable per cent seed infestation, along with the economics in consideration, soybean oil @ 5ml /kg seed and castor oil @ 5ml /kg seed were found effective and cheaper in respect of management of pulse beetle in stored green gram than other botanicals.
