• Nanoformulations
• polyethylene glycol
• synthetic fungicides
• UV spectrophotometry

We have recently reported the development of nanosulphur with remarkable fungicidal properties, much better than the conventional sulphur. The nanosulphur could substitute the toxic conventional synthetic fungicides. The lack of estimation protocols for active ingredient in nanoformulations and exploitation of nanosulphur as a new technology for fungal management necessitates the need for estimation protocols to ensure the quality and quantity of sulphur in nanoformulations. Therefore, a method was developed for the estimation of sulphur in its nanoformulations using UV-visible spectrophotometry. Thirty-four samples of nanosulphur were analysed to validate the method. The percentage estimation of the active ingredient in all the samples was above 80.
