Formulation and Evaluation of Herbal Liquid Insecticide
Abstract
Extensive usage of commercially available synthetic pesticides against phytophagous insects has resulted in their bio-accumulation in the environment, leading to a rise in resistance and a decrease in soil biodiversity over time. In addition, 90% of the sprayed pesticides penetrate the different natural resources via runoff, exposing farmers and consumers of agricultural products to serious health risks. As a result, increasing emphasis has been placed on the creation of environmentally benign pesticides/insecticides that would enable an effective pest management system and minimise chronic exposures that contribute to illnesses. The utilization of the herbal active compounds with insecticidal activities is one such technique. Hence the aim of this study was to develop herbal insecticide formulations from extracts of leaves of Azadirachta Indica, Datura Stramonium, Cascabela Thevetia and seeds of Annona Squamosa. Insecticidal efficacy of developed formulations was tested in-vitro against ballworm larvae. The study unveiled its significance in developing herbal insecticidal formulations as an alternative to harmful synthetic chemical insecticides and a step forward towards development of a promising eco-friendly technology in crop protection.
Keywords: Insecticides, Biopesticide, Azadirachta indica, Datura Stramonium, Annona Squamosa, Cascabela Thevetia.
