dc.description.abstractFive 2-oxobenzoatometal complexes viz. tetraaquo(2-oxobenzoato)zinc(II) dihydrate (1), sodium diaquobis(2-oxobenzoato)zincate(II) (2), sodium tris(2-oxobenzoato)zincate(II) (3), diaquo(2-oxobenzoato)copper(II) dihydrate (4) and sodium bis(2-oxobenzoato)cuprate(II) (5) were synthesized using a standard methodology having different molar ratios of metal and 2oxobenzoato ligand (salicylate ligand). They were further nanoformulated via. sonication and laser disintegration technique (blue laser). The in vitro antifungal evaluation revealed more profound results of laser disintegrated samples for inhibiting the fungal menace of two seed borne fungal pathogens of rice viz. F. fujikuroi and F. verticillioides. Sodium bis(2oxobenzoato)cuprate(II) (l-CuSA2) was the most effective in inhibiting the mycelium growth of both the test fungi i.e. F. fujikuroi and F. verticillioides, with ED90 values of 2347.17 + 0.28 μg/ml and 2373.41 + 0.47 μg/ml, respectively. Nanopriming of most infested rice seeds (PUSA 1509) with l-CuSA2 at 2500 μg/ml showed the best seed health and quality parameters and is accounted as the best nanoformulated complex which have opened the doors for further elaborative study for its utilization as seed nanopriming agent in agrosystems to replace Carbendazim (banned fungicide) for seed treatment.
