In-vitro efficacy of fungicides against Alternaria alternata causing blight disease of tomato (Solanum lycopersicum L.)

Tomato is world’s one of the largest growing vegetable crop and ranks first among processing crops. It’s production suffers with many biotic and abiotic factors. Leaf blight disease caused by different species of Alternaria is one of the most dreadful diseases of tomato, causing huge economic losses. The present study was conducted in order to evaluate the efficacy of different fungicides against Alternaria alternata, one of cause for blight disease of tomato. | Int.J.Curr.Microbiol.App.Sci 2021 10 03 915-920 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 10 Number 03 2021 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2021.1003.115 In-vitro Efficacy of Fungicides against Alternaria alternata causing Blight Disease of Tomato Solanum lycopersicum L.

It s production suffers with many biotic and abiotic factors. Leaf blight Tomato Alternaria disease caused by different species of Alternaria is one of the most dreadful diseases of alternata tomato causing huge economic losses. The present study was conducted in order to Fungicides Percent evaluate the efficacy of different fungicides against Alternaria alternata one of cause for mycelial growth blight disease of tomato. The efficacy of fungicides viz. Propineb 70 WP Hexaconazole inhibition 5 EC Propiconazole 25 EC Azoxystrobin 23 SC Mancozeb 75 WP Tebuconazole 50 Trifloxystrobin 25 WG and Carbendazim 12 Mancozeb Article Info 63 WP was tested at different concentrations viz. 100 150 200 and 500 ppm against A. alternata on PDA by poisoned food technique. It was concluded that maximum Accepted mycelial growth inhibition 97.96 was recorded by Hexaconazole followed by 10 February 2021 Tebuconazole Trifloxystrobin 94.17 . However Propineb recorded least per cent Available Online inhibition of mycelium growth at all concentrations with a mean percent growth inhibition 10 March 2021 of 60.83 percent. Introduction region but consumed world widely because it contains .
