Abstract
Phytotoxic induction by imidacloprid and its nano form on the cucumber plant and the adverse impact on the tissue culture of HepG2 cell line were demonstrated. Nano-form of imidacloprid was loaded on chitosan nanoparticles (NPs). Significant increase in the plant morphological parameters was noticed after the last periods. The nano-form exhibited significant increases in the fruits yield greater than the traditional form. Also, the quality recognized the same pattern. All treatments of the nano-form: dose, 1/2 dose and 2-times dose showed an increase in the leave pigments greater than the traditional form. The bio-safety procedure on HepG2 cell lines showed a slight difference between the traditional and nano-form (1.22-folds). However, lactate dehydrogenase (LDH) activity and malondialdehyde (MDA) level showed significant increases in the treated cells, respect to their controls. Nano-formulation practices have advantages on the vegetable crops to increase their characteristics. Further toxicological studies must be required before field particles.
