Abstract
Powdery mildew, caused by Podosphaera pannosa, is the most widespread and economically important disease in commercial production of cut roses.
Two control trials were carried out at Sanremo (Northern Italy) on roses cv. ‘Pretty Woman’ grown in a soilless system.
The effectiveness of azoxystrobin, of the new compound boscalid, and of three biorational fungicides, such as the salt monopotassium phosphate (KH2PO4) and the vegetable oils NTI 3404 (Sea-Crop Synergy B) and NTI 3412 (Sea-Crop Synergy F), was tested.
Foliar treatments were applied weekly for 6 times.
The products assayed in both experiments appeared equally effective in limiting powdery mildew to a satisfactory level.
