| Summary: | Apple scab, which is caused by the fungus Venturia inaequalis, is one of the most
important diseases of apple trees. It mainly affects leaves, fruits, and sometimes also
flowers and shoots. The aim of this work was monitoring the resistance of Venturia
inaequalis to pyrimethanil and stobilurins fungicides. Part of our work included
evaluation of the monitoring and assignment of the population to the relevant category
of resistance to the active substances. A total of 46 populations were tested. Our
results show that the population of V. inaequalis was generally more sensitive to
pyrimethanil while resistant to strobilurins. A large percentage of the populations
(76 %) was sensitive to pyrimethanil and just 1 was moderately resistant, only 31 % of
the population was sensitive to strobilurins and 62 % were resistant. |
