Abstract:
Callosobruchus chinensis is a major stored pest of pulses in India. Efficacy of botanicals against pulse beetle in stored green gram was studied at the laboratory of Department of Entomology, Faculty of Agricultural Sciences, SOADU, Bhubaneswar during the month of June to January in the year 2019-20. Eight treatments including untreated (control), comprising of Tulsi leaf powder (5g/kg seed), Neem leaf powder (5g/kg seed), Black pepper seed powder (5g/kg seed), Sweet flag (Acorus calamus) rhizome powder (5g/kg seed), Dry chilli powder (5g/kg seed), Lantana camara leaf powder (5g/kg seed) and Tobacco leaf powder (5g/kg seed) were used against adult pulse beetle, C. chinensis in stored green gram seed. Effect of seven botanicals on mortality of C. chinensis Linn. were studied. Observations were taken on 2, 4 and 6 days after treatment. Among all the plant products, neem leaf (5g/kg seed) was found more effective with 35.63 % mortality whereas black pepper powder (5g/kg seed) was found least effective with 10.25 % mortality.
