Sclerotium rolfsii was affect the many crops including wild and cultivated crops and make the destructive yield losses. It producing resting structure (sclerotia) survive in the soil upto 14 years. Which producing mycelium colonized on the any plant part which attached to the soil and disintegrate the tissues followed by reduce the economic quality of crops. These pathogens produce the mustard shape brown colour sclerotia and hyaline septate mycelium, which characters varied based on the isolates where collected. This septate mycelium penetrates the stem region, these penetrated mycelium stem region were observed on the Scanning Electron Microscope. Which sclerotia and mycelium also observed on the SEM.
