Abstract

Late blight caused by Phytophthora infestans is one of the main diseases in potato production. It not only adversely affects tuber yield and economy of potato growers, but also reduces produce quality. The present investigation was carried out at Balindi Research Complex Farm of Bidhan Chandra Krishi Viswavidyalaya, West Bengal during Rabi season of 2018-2019, to evaluate the impact of spot application of cymoxanil 8% + mancozeb 64% WP @ 2.5 gm per liter of water to manage late blight of potato. The fungicide was applied as spot application 35 days after appearance of disease in three different tillage and a combination of rice residue and different doses of N, P and K fertilizer treatments of cultivar Kufri Jyothi. It was observed that, among all the treatments, zero tillage (12.50) with treatment 100% paddy straw residue + 75% NPK resulted in least disease incidence. Whereas, lower disease severity was recorded by zero tillage (3.06) after application of fungicide with treatment 50% paddy straw residue+100% NPK.
