A field experiment was carried out in 2019 to assess the efficacy of two fungicides namely cytrol 75% WP (thiophanate methyl 35% + chlorothalonil 40%) and revus 240 SC (mandipropamid) to control late blight of potato caused by Phytophthora infestans, under field conditions. The experiment was carried out in a randomized complete block design. There were four treatments viz. control, cytrol @ 500 g acre-1, cytrol @ 600 g acre-1 and revus 240 mL acre-1. Data regarding disease incidence and disease control were recorded on 3rd, 5th and 7th days after spray. On day 7th, the highest disease incidence (74%) was recorded in control. All three fungicide treatments significantly reduced disease incidence. Cytrol @ 500 and 600 g acre-1 treatments reduced the disease incidence to 28% and 25%, showing 62% and 66% disease control potential, respectively. Likewise, application of revus 240 mL acre-1 reduced disease incidence to 28% exhibiting 62% disease control potential over control. This study concludes that cytrol @ 500 g acre-1 and revus 240 mL acre-1 can effectively control late blight of potato under field conditions.References
