dc.description.abstractEssential oil based bioherbicides are topic of interest for the new era agriculture because of their sustainable use in the control of weeds. The present study aims to formulate nanoemulsion of celery (Apium graveolens L.) essential oil (EO) and evaluate its herbicidal activity against Phalaris minor Retz. and Avena ludoviciana Durieu. Chemical composition of EO from seeds A graveolens showed presence of thirty-seven compounds amongst which limonene (76.95%) was the major compound. Nanoemulsions were fabricated by high frequency ultrasonic method and phase diagram was mapped and optimum O/W formulations were selected. The physicochemical properties recorded for nanoemulsion indicated their O/W and isotropic nature. Transmission electron microscopy (TEM) and Zavg indicated spherical nature of droplet with average size to be > 21 nm. The prepared formulations were stable to storage and centrifugation. Formulated emulsion and nanoemulsions having 0.05% and 0.1% A. graveolens EO completely inhibited the germination of P. minor and A. ludoviciana by adversely affecting the physiological processes like seed imbibition and membrane leakage mediated cellular damage without having adverse effect on Triticum aestivum.en_US
