Bioefficacy evaluation and phytotoxicity studies on fungicide Taqat 75%WP (Captan 70% + Hexaconazole 5%) against early blight and powdery mildew diseases in tomato crop
Year: 2020
Type: article
Abstract: Tomato crop is attacked by several pathogens during its cropping season. The present study was undertaken to mitigate the disease incidence using Taqat 75% WP during the year 2016-17 and 2017-18. Assessment of the disease severity was done by standard scoring methods and expressed as Per cent Disease Index (PDI). For phytotoxicity of Taqat 75%WP at X dose 750g/ha, 2X dose 1500g/ha and 4X doses 3000g/ha along with the standard check treatments. The observations on leaf injury, wilting, vein clearing, necrosis, epinasty & hyponasty were recorded on ten randomly selected plants before spray at 3, 7 and 15 days after 1st spray. The observations were recorded on early blight and powdery mildew before application and at different intervals after the application of Taqat 75%WP.Thus, our studies revealed that the per cent disease index of Taqat 75%WP (Captan 70% + Hexaconazole 5%) @ 750 g/ha is highly effective in controlling Early blight and powdery mildew diseases of tomato and increasing tomato fruit yield without causing any phytotoxicity to the crop.
