Unique Characteristics of Dried Rose Buds
In the early stages of infection, blister-like prominent areas, often red, form on the upper surface of the leaves. Contamination over time leads to a decrease in flower quality. In case of intense activity of powdery mildew, leaf growth, photosynthetic efficiency, and as a result of plant growth and transaction value of cut flower branches will decrease. It seems that the number of flowers will also decrease, but this has not been definitively confirmed yet. With the growth of mycelium and conidiophores of the fungus, white areas form on the leaves that, as the disease progresses, cover the entire surface of the young leaves like white powder, causing them to become entangled and deformed.
The adult leaf area is usually not completely covered by the fungus. Older leaves also form circular or irregular shapes that result from fungal growth, but older leaves are less likely to deform than younger leaves. If environmental conditions are favorable for fungal growth, powdery mildew also dried rose buds wholesale the stem, and in the early stages of infection, it multiplies and grows on the soft and juicy tissues of the stem, especially in the base of the blades and the area where they attach to the stem.

In such cases, protective fungicides should be used. The correct timing of reuse of fungicides is very important due to the rapid growth of young stems that are susceptible to this disease. Pruning of infected stems at the end of the growing season and removing these stems in areas with very cold weather during the winter will prevent the fungus from overwintering.
