This study focuses on the development, formulation, and in vitro evaluation of the biological efficacy of NANO-BIa novel nanoemulsion system composed of neem oil and cinnamon essential oildesigned for the effective control of Tetranychus sp. on tomato (Solanum lycopersicum) plants. Fourier-transform infrared spectroscopy analysis revealed characteristic alterations in functional groups, confirming the successful formation of the emulsion. The nanoformulation exhibited an average particle size of approximately 206 nanometers and a zeta potential of -55.7 mV, indicating excellent colloidal stability and dispersion uniformity. In bioefficacy trials, NANO-BI significantly outperformed the conventional chemical pesticide Vineem 1500EC, achieving an outstanding mortality rate of 98.33 - 100% within just 1 to 3 days at a concentration of 0.50%. Moreover, it maintained a high level of effectivenessranging from 95% to 100%even at the lowest tested concentration of 0.125%. These promising results suggest that NANO-BI is not only highly effective and fast-acting against Tetranychus sp., but also represents a strong candidate for sustainable, eco-friendly pest management solutions in agriculture.Downloads
