Abstract: Different contact and systemic fungicides were evaluated in vitro against Alternaria cucumerina. Amongst contact (non-systemic) fungicides evaluated maximum inhibition in mycelial growth was observed in mancozeb (99.98%) and thiram (99.98%) followed by copper oxychloride (87.60%). Among the different concentrations tried, Mancozeb and thiram showed strong inhibition at all concentration, while copper oxychloride gave 88.51% growth inhibition followed by copper hydroxide (85.51%) at 2500 ppm concentration. Out of seven systemic fungicides, propiconazole, difenoconazole and azoxystrobin found best with 99.98% mycelial growth inhibition followed by picoxystrobin (70.64%). Similarly, propiconazole, difenoconazole and azoxystrobin showed maximum inhibition of mycelial growth (99.98%) of the test fungus at all concentration.
