Abstract

Among the different concentrations of SAAF (Carbendazim 12% & Mancozeb 63%) i.e. 0.1, 0.2, 0.4, 0.75 and 1.0%, 0.75% was found most effective in reducing mycelial growth of Rhizoctoniasolani. Comparative evaluation of SAAF with other fungicides (Companion and Carbendazim) and biocides (Neem & T. harzianum) revealed that SAAF is most effective in reducing mycelial growth of the pathogen, showing 2.3 cm in diameter against 9.00 cm in control. The minimum disease incidence with 14.75% was also recorded by foliar spray of SAAF @ 0.75 which was followed by companion @ 0.5% (18.22%).
