Abstract

Root and crown rot disease of apple trees is important in different regions of the world and causes considerable damage to apple orchards around the world annually. Due to the presence of newly known fungal agents in apple growing areas of Isfahan province, sensitivity of Fusarium solani and F. oxysporum species as the most abundant identified species of decay of apple trees compared to common fungicides including Tilt, Eminent, Cabrio Duo, Collis, Ortiva Top, Lamardor, Uniform, Flint, Stroby, Rovral TS and Topsin M at concentrations of 10, 25, 50, 100 and 200 mg/l were tested in vitro. Lamardor, Rovral TS, Ortiva top and Tilt fungicides at the highest tested concentrations in both Fusarium species and Eminent at all tested concentrations in F. oxysporum resulted in more than 50% mycelial growth inhibition in vitro, in comparison with the other fungicides. Although, performing a laboratory test is very useful in the initial screening of fungicides, but in order to definitively recommend a fungicide to control the disease, in addition to fungicides experiment in vitro, testing in greenhouse and field conditions is also necessary.
