About this document
Managing Rose Diseases with Fungicides by AZIZRAHMANABUBAKAR is a document available to read on EtoBox.
The document discusses several diseases that affect roses: 1. Black spot, caused by the fungus Diplocarbon rosae, produces black lesions on leaves which cause premature defoliation and reduced flower production. 2. Powdery mildew, caused by Sphaerotheca pannosa, appears as a grayish-white powder on leaves and buds which can distort leaves and reduce flower quality. 3. Dieback, caused by Diplodia rosarum, causes drying and blackening of twigs which spreads to roots and can kill entire plants.
