In vitro sensitivity of the tomato early blight disease agent Alternaria alternata to some fungicides

Abstract

Early leaf blight is a common fungal disease caused by Alternaria alternata (Fr.) Keissler. Various fungicides are used for the chemical control of this disease. As a result of the frequent use of fungicides, decreased susceptibility to the pathogen may be observed. In this study, the susceptibility of early leaf blight (A. alternata), a problem in tomato plantations, to azoxystrobin, tebuconazole and mancozeb was determined. Sixty A. alternata isolates were obtained from 121 infected plant samples collected from the Antalya, Ankara, Bartın, and Zonguldak provinces in 2013 and 2014. Pathogenicity tests revealed that the disease severity of the isolates varied between 50% and 85% on average. The susceptibility of the isolates to azoxystrobin, tebuconazole, and mancozeb was determined by radial growth tests, and ED50 values against azoxystrobin, tebuconazole and mancozeb were determined to be 0.4 ppm, 0.6 ppm and 0.6 ppm, respectively. Polatlı was the most susceptible isolate to the three active substances. Alanya isolate to azoxystrobin (ED50= 452 ppm), Derbent isolate to mancozeb (ED50= 14.45 ppm), Serik and Kayaburnu isolates to tebuconazole (ED50= 33.61 ppm) were determined as the highest resistance isolates. As a result of the study, it was determined that some of the isolates developed resistance to these fungicides.
