Ecofriendly and sustainable management of Spilosoma obliqua Walker on sesame (Sesamum indicum L.) crop by new botanicals

Arindom Parui and Nayan Roy

Sesame (Sesamum indicum L., cv. Rama) is a widely used oldest oil seed crop throughout the world and they are highly affected by different herbivorous insect pests including Spilosoma obliqua Walker. We investigated the efficacy of two botanicals [mahogany (Swietenia mahagoni) and Indian beach or karanja (Millettia (Pongamia) pinnata) leaf extract] in 5% neem oil individually and in combined mixture for determination of LC90 by Log-probit analyses. Due to lowest LC90 value of the combined botanicals in 5% neem oil (16.49%, w/v) over the synthetic pesticide (indoxacarb @ 5%) was used for sustainable and ecofriendly management of S. obliqua on the crop in the field conditions. The seed production were significantly increased (F1,19=21.145, P<0.0001) from 4.844 to 296.546 kg/hector in botanical pesticide treated plots over the synthetic pesticide. Thus the result demonstrates the potential of new botanicals in control of the pest in future integrated pest management (IPM) programmes.
