Evaluation of the sensitivity of Leptosphaeria maculans isolates causing phoma stem canker in oilseed rape in the Czech Republic to boscalid and dimoxystrobin fungicides
Original language description
Phoma stem canker, caused by Leptosphaeria spp. is generally managed with demethylation inhibitor (DMI) fungicides in the Czech Republic. However, there have been reports of resistance to DMIs in L. maculans populations. Fungicide resistance management recommends the application of fungicides with different modes of action, either as mixtures or in rotation with other fungicide classes. The objective, therefore, was to evaluate the efficacy of boscalid, dimoxystrobin and a mixture of boscalid and dimoxystrobin, belonging to the succinate dehydrogenase inhibitor and quinone outside inhibitor fungicide groups, respectively, on L. maculans isolates. A total of 41 and 285 isolates were tested using the mycelial growth and microtitre plate assays, respectively. The EC50 values for the mycelial growth plate method ranged from 0,026 to 0,984 microgram/mL and 0,097 to 1,653 microgram/mL for boscalid and boscalid plus dimoxystrobin, respectively. For dimoxystrobin, the EC50 range was wide, between 0,053 and 95,59 microgram/mL. The EC50 values for the microtitre plate assay ranged from 0,001496 to 0,8363 microgram/mL and 0,00073 to 2,801 microgram/mL for boscalid and dimoxystrobin, respectively. The results also showed that the L. maculans conidia were more sensitive to boscalid and dimoxystrobin than mycelia.
