Abstract:
Like other crops, raspberry plant gets infected by many infectious diseases. Among them,
powdery mildew disease causes significant damage. This article outlines the results of the study
on the pathogens of powdery mildew disease of raspberry, incidence of diseases on the farms, as
well as severity of diseases. Besides, the data on yield loss of this disease and testing of the
fungicides against powdery mildew disease of raspberry with active ingredients Flusilazole,
Difenoconazole + ciflufenamid and Penconazole have been presented. In this case, fungicides
against powdery mildew were used during the emergence of the first flower buds of raspberry
and in the periods before flowering. The highest biological efficacy was noted in the variants
with fungicide Cideli Top 140 DC (125 g/l Difenoconazole + 15 g/l ciflufenamid) and its
indication was 79,6-90,0%. At a rate 0,7 l/ h?, twice application of Cideli Top 140 DC fungicide
during the emergence of the first buds of raspberry and before flowering resulted effectively and
its biological efficacy showed 90,0%. While in the variants with fungicide Omad, 40% EC,
biological efficacy was 71,9-80,5%. |
