Evaluation of Pydiflumetofen 7.5% + Difenoconazole 12.5% w/v (200 SC) on tomato against early blight (Alternaria spp), and powdery mildew (Leveillula taurica) under field condition

Abstract

The tomato is the edible, often red, berry of the plant Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America and Central America. Despite botanically being a fruit, it’s generally eaten and prepared like a vegetable. Tomatoes are the major dietary source of the antioxidant lycopene, which has been linked to many health benefits, including reduced risk of heart disease and cancer. Early blight caused by Alternaria solani and powdery mildew caused by Leveillula taurica has become a serious problem for successful cultivation of tomato. Therefore, a field experiment was carried out on the effect of Pydiflumetofen 7.5% + Difenoconazole 12.5% w/v (200 SC) on Tomato against early blight (Alterneria spp), and Powdery mildew (Leveillula taurica) during 2016-17 and 2017-18, at College of Horticulture, Hiriyur. Experimental results revealed that all the treatments significantly reduced the early blight and powdery mildew disease severity over untreated control. Amongst all the treatments in both seasons significantly least disease severity of early blight (6.25 and 5.50%) and Powdery mildew (2.50 and 3.00%) was recorded with foliar application of 1.2 ml of Pydiflumetofen 7.5% + Difenoconazole 12.5% w/v (200 SC) with yield of 8.83 and 9.42 t/ha followed by the application of 1 ml of Pydiflumetofen 7.5% + Difenoconazole 12.5% w/v (200 SC).
