Abstract
Systemic fungicides, carbendazim + mancozeb and carbendazim alone completely inhibited the mycelia growth even at 100 and 200 ppm, whereas among non-systemic fungicides, thiram was found to be the most effective and gave 52.77, 62.77 and 85.00% inhibition at 500, 1000 and 1500 ppm concentrations, respectively. Thiram was found to be most effective fungicides in inhibiting the both fungi (68.84 and 58.69%) followed by the indofil M 45 (47.59 and 51.38%). In pot house condition, carbendazim + mancozeb (0.2%) and carbendazim (0.1%) were most effective fungicides in reducing cent percent disease incidence and severity, but it was at par with thiram (82.35; 87.50). In field condition, mulching with transparent polyethylene mulch (25 μm) resulted in highest survival rate (95.83%) and least mortality rate (4.16%) of rooted geranium cuttings after 30 days of germination. The application of carbendazim (Bavistin) at 0.1% when applied individually was also found almost complete control as is evident from low disease incidence (1.04%) and severity (0.52%), considered to be second best treatment. Apparent infection rate (0.0) was observed in carbendazim + mancozeb and carbendazim followed by copper oxychloride (0.006) and carboxin (0.009). Area under disease progress curve was less than 100 in cabendazim + mancozeb and carbendazim.
