Determination of Bioefficacy and Phytotoxicity of Fungicide Taqat 75% WP (Captan 70% + Hexaconazole 5%) against Leaf Spot and Fruit Spot Diseases in Tomato Crop
Year: 2020
Type: article
Abstract: Several pathogens attack the tomato cropduring its cropping season. The present experiments were carried out to study 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 leaf spot and fruit spot before application and at different intervals after the application of Taqat 75%WP. Thus, our studies revealed that the per cent disease index (PDI) of Taqat 75%WP (Captan 70%+Hexaconazole 5%) @ 750 g/ha is highly effective in controlling leaf spot and fruit spot diseases of tomato and increasing tomato fruit yield without causing any phytotoxicity to the crop.
