Evaluation of certain botanicals against pulse beetle, Callosobruchus chinensis (L.) on chickpea

Abstract

Pulses, a poor man’s meat in which many insect pests causes losses in both field and storage condition. In storage condition, the pulse beetle, Callosobruchus spp. causes major losses among other Pests. The present study involves the evaluation of certain botanicals like Neem leaf powder 5g/ 100 seeds, Nimbicidin 5ml/ 100 seeds, Karanji oil 5ml/ 100 seeds, Custard apple leaf powder 5g/ 100 seeds, Castor oil 5ml/ 100 seeds and Eucalyptus oil 5ml/ 100 seeds against C. chinensis in chick pea for percent seed infestation and percent seed weight loss, where Deltamethrin (2.8 EC) 0.04ml/ 100 seeds and untreated treatments used as standard check and untreated check respectively. The results revealed that all the treatments was significantly superior then the untreated control that have maximum insect damage (9.0%) at 30 days of storage period. Insect infestation percent was increased in all the treatments with period increased in storage and nature of protectants. Minimum percent infestation and percent weight loss were noted in Deltamethrin (2.8 EC) 0.04ml/ 100 seeds followed by Nimbicidin 5ml/ 100 seeds and highest were in untreated control.
