Question: Diseases of the maonia
I reside in Asti I am writing to you because I have a problem with the Monia that I have just planted in the garden (in March), as soon as it was planted it was beautiful and the leaves that were red (in winter) were already completely changing their color to green, however unfortunately lately the leaves are turning red and brown in patches, how can I understand if the problem is transient and that is suffering
for the recent change of terrain or if he is dying ???? is it correct to prune branches with dry leaves ??? is it possible to help her in any way ???
What diseases does Maonia suffer from ????
Mahonia diseases: Answer: Maonia diseases
Maonia is substantially sensitive to three diseases caused by fungi: Uropyxis sanguinea (leaf rust); Colletotrichum mahoniae (leaf spots); Oidium spp. (badly white). The symptoms she exhibited seem to describe advanced stages of the second pathology, that caused by Colletotrichum mahoniae. First of all it is necessary to eliminate the dry and seriously deteriorated parts. After cutting, two treatments are performed
15-20 days apart from each other with a product based on the active ingredient Benomyl (commercial product Fitomyl at a dose of 10 grams per 10 liters).
