Type: article
Abstract: The study was conducted in field conditions for two growing seasons during rabi 2017-18 and rabi 2018-19 (On Farm Testing - OFT) by ICAR-Krishi Vigyan Kendra, Kolar, Karnataka to develop effective integrated approach against downy mildew of cucumber. In the study, the approach comprising of soil application of Trichoderma harzianum enriched farm yard manure (@1 kg/100 kg FYM spot application), Seed treatment with Metalaxyl (2g/kg seeds), Prophylactic spray with Mancozeb @ 0.25% before onset of the disease followed by Curative sprays with Metalaxyl + Mancozeb @ 0.2%, and Dimethomorph @ 0.1% + Mancozeb @ 0.2% at weekly interval at onset of the disease was found most effective against the disease in field conditions. Further, the same approach was found superior in terms of yield and economics over control. Thus, this approach will be a suitable alternative to sole chemical management and will serve as effective IDM against downy mildew of cucumber under field conditions.
