Abstract:
Background: Among the world’s flowers, the rose has captured the heart and soul of all. It is the symbol of love. Rose suffers from many foliar diseases and among them black spot caused by Diplocarpon rosae Wolf is one of the most important disease of rose, this disease is economically devastating disease in ornamental rose especially in hot and humid climates. Considering severity and its destructive nature, the study was under taken to find out the most effective and economic fungicides against the black spot of rose with objective to test the efficacy of different fungicides against black spot of rose.
Background: Among the world’s flowers, the rose has captured the heart and soul of all. It is the symbol of love. Rose suffers from many foliar diseases and among them black spot caused by Diplocarpon rosae Wolf is one of the most important disease of rose, this disease is economically devastating disease in ornamental rose especially in hot and humid climates. Considering severity and its destructive nature, the study was under taken to find out the most effective and economic fungicides against the black spot of rose with objective to test the efficacy of different fungicides against black spot of rose.
Methods: D. rosae causing black spot of rose was isolated from infected rose plants collected from Department of horticulture, College of Agriculture, Nagpur on potato dextrose agar medium (PDA) and later its pure culture accomplished. The culture of the pathogen was examined microscopically for morphological and culture characteristics. In the present study of investigation efficacy of various fungicides viz., azoxystrobin 0.1%, mancozeb + carbendazim 0.2%, topsin 0.05%, myclobutanil 0.1%, tebuconazole 0.1%, chlorothalonil 0.2% were evaluated In vitro and their economics was computed.
Result: The fungicidal along with untreated control were evaluated against Diplocarpon rosae by poison food technique and per cent inhibition in mycelia growth. Results indicated that, all the rest fungicides significantly inhibited the growth of Diplocarpon rosae over untreated control. Highest inhibition was observed by chlorothalonil 75 WP @ 0.2% (90.74 per cent) and topsin M 70 WP @ 0.05% (81.72 per cent) found effective to control black spot disease of rose over all the test fungicides followed by myclobutanil 10 WP @ 0.1% (79.78 per cent).
