Market demand for blackberry fruit (Rubus fruticosus L.), that’s production is more and more being widespread both in
the world and Turkey, is increasing. The most important factor negatively affecting blackberry yield is fungal diseases
but there are not any approved fungicides in Turkey to combat those diseases. This study was carried out in Bursa,
Turkey's leading raspberry and blackberry production region, to develop organic and conventional management
programs for controlling blackberry cane and leaf rust caused by Kuehneola uredinis (Link) Arthur, which was
prevalently observed in blackberry orchards. Copper fungicides (20% copper calcium sulfate) were used to determine
the efficacy against the disease as an organic spraying program. An IPM program recommended to control of blackberry
cane and leaf rust disease in the State of California in the United States of America was applied to blackberry orchards in
Bursa conditions as a conventional spraying program (by using fungicides with active substances Pyraclostrobin +
boscalid and myclobutanil). The evaluations made within the scope of the study were done before the harvest in early
June 2016, when the severity of the disease increased to 26% in the control parcels. In the evaluation, the effectiveness
of the organic spraying program that was applied in the same way as the producers do was determined just as 7.69%,
while the effectiveness of the conventional spraying program was found as 75%. It was observed that the applied
organic spraying program did not reach sufficient efficiency. However, it is thought that conventional spraying program
examined might be used in control of the disease with some improvement.
