The efficacy of five fungicides evaluated at range of 1000, 2000, 3000, 4000, 5000 ppm concentration by poison food technique against Alternaria brassicae under In-vitro conditions. The observations on colony diameter and percent inhibition of linear growth of Alternaria brassicae. Mancozeb, combination of Mancozeb Metalaxyl, Bavistin and Chlhorothalonil in which combination two fungicide viz Mancozeb, Mancozeb and Metalaxyl were effective against Alternaria brassicae. Mancozeb was significantly inhibited mycelial growth of Alternaria brassicae at 2000 ppm. The combination of both Mancozeb and Metalaxyl was also completely inhibited mycelial growth at 2000 ppm. Bavistin and chlorothalonil were showed least effective against Alternaria brassicae at all concentrations compared to all fungicides. The Mancozeb and combination of Mancozeb and Metalaxyl were found most effective in inhibition of the mycelial growth and Bavistin and Chlorothalonil fungicides were found least effective.
