Abstract:
The present investigation was carried out at Plant Pathology Section, College of Agriculture, Dhule. The material and methods used, and procedures followed to investigate the “Effect of fungicides on Sclerotium rolfsii isolates of groundnut from Khandesh region” Sclerotium rolfsii Sac is a destructive soil borne fungal pathogen with wide host range that includes groundnut, an important oil seed crop in India. The fungicides Propiconazole and Tebuconazole recorded cent percent mycelial inhibition followed by SAAF, Carbendazim, Benomyl, Captain, Rodomel and Thiophanate methyl. The results also indicated that all the six isolates recorded no effect of fungicides on colony color, shape of sclerotia bodies, color of sclerotia bodies, position of sclerotia bodies and numbers of sclerotia bodies present in one position. It was also pointed out that the increase in the concentration of fungicides doesn’t have any effect on colony color, shape of sclerotia bodies, color of sclerotia bodies, position of sclerotia bodies and numbers of sclerotia bodies present in one position. The variation in size of sclerotia bodies, number of sclerotia bodies per cm2 and test weight of sclerotia bodies among all the six isolates due to effect of eight fungicides were found statistically significant. The fungicide SAFF was most effective in reducing size of sclerotia bodies, number of sclerotia bodies per cm2 and test weight of sclerotia bodies followed by Carbendazim and Benomyl. While the fungicide Thiophanate methyl was less effective in reducing size sclerotia bodies, number of sclerotia bodies per cm2 and test weight of sclerotia bodies followed by Rodomel. It was also pointed out that the increase in the concentration of fungicides there was reduction in size of sclerotia bodies, number of sclerotia bodies per cm2 and test weight of sclerotia bodies among all the six isolates.
