title: Effectiveness of Different Classes of Fungicides onBotrytis cinereaCausing Gray Mold on Fruit and Vegetables.
abstract: Botrytis cinereais a necrotrophic pathogen causing a major problem in the export and post-harvest of strawberries. Inappropriate use of fungicides leads to resistance among fungal pathogens. Therefore, it is necessary to evaluate the sensitivity ofB. cinereato various classes of fungicide and to determine the effectiveness of different concentrations of commonly used fungicides. We thus evaluated the effectiveness of six classes of fungicide in inhibiting the growth and development of this pathogen, namely, fludioxonil, iprodione, pyrimethanil, tebuconazole, fenpyrazamine, and boscalid. Fludioxonil was the most effective (EC50< 0.1 μg/ml), and pyrimethanil was the least effective (EC50= 50 μg/ml), at inhibiting the mycelial growth ofB. cinerea. Fenpyrazamine and pyrimethanil showed relatively low effectiveness in inhibiting the germination and conidial production ofB. cinerea. Our results are useful for the management ofB. cinereaand as a basis for monitoring the sensitivity ofB. cinereastrains to fungicides.
