  Being the important organic reaction intermediates and biological scaffolds, a series of 2-alkyl/aralkyl/ heterocyclyl sulfanyl-5-amino/methyl-1,3,4-thiadiazoles have been synthesized by suitable synthetic route and characterized by analytical and spectral data. The evaluation of these compounds for their bioefficacy against two phyto-pathogenic fungi revealed their fungicidal potency against Rhizoctonia bataticola (ED50 values, 3.9-300.4 mu g/mL) and Rhizoctonia solani (ED50 values, 4.2-228.5 mu g/mL). To further augment their fungicidal efficacy, the potent five fungicidal compounds were nano-sized. The protocol for preparing 1,3,4-thiadiazole based nano-fungicide employing polyethylene glycol was developed and standardized. Characterization of nano-forms of 1,3,4-thiadiazole derivatives by particle size analyzer and electron microscopy (TEM) techniques confirmed the <100 nm average particle sizes of all nano-fungicides. The 2-4 times higher fungicidal activity was observed with nano-forms than the corresponding conventional sized 1,3,4-thiadiazole derivatives against phytopathogenic fungi, namely, Rhizoctonia solani and R. bataticola.
