Problems with the bay hedge

I reside in S. DonŠ° di Piave (VE) I am writing to you because I have a problem with the laurel hedge which continues to get sick continuously in the summer. Up to now I have pruned some sections of the hedge in winter and then find myself in the summer as before if not worse. After listening to an expert, I was told that the plant was infected with Mal Bianco, which causes the leaves to crumple up once they are sick, causing necrosis. The strange thing is that he told me that the only disease of the laurel is precisely this Mal Bianco, which has not completely convinced me, in fact I am kindly asking you what are the diseases that can affect the laurel most frequently and how they go treated. What I have noticed is that some leaves, only the top ones, have the characteristic curling due to Mal Bianco while some leaves, those we say ripe towards the central part of the plant, have in addition to the characteristic color of yellowish leaf, on the lower part it has some black specks and is not crumpled at all. Traits of the hedge are more diseased than others and the leaves fall continuously from summer and throughout the winter season. I would be really grateful if you could give me some advice, thanking you in advance I offer you my warmest regards.


Lauro hedge: Problems with the laurel hedge

Dear Graziano,

thank you for reading our magazine and sending us this e-mail.

As far as your question is concerned, the discussion is more complicated than it might seem at first glance. If you can console her, we can say that your problem is very frequent and affects a bit all those like you who have one laurel hedge ceraso. It is true that the most common disease of the laurel is white sore, but it is not the only one. There are in fact diseases that attack the root system and others that derive from nutritional deficiencies.

The diseases most frequently affecting the laurel are: waxplasts, iceria, mal white, psylla, Mediterranean tortrice, ramic desiccation and rizottoniosis. These are present throughout Italy even if with different diffusion in relation to the region and climatic conditions. In the specific case, from what can be understood from the description, plants have two diseases.

The apical part is affected by white sore. To combat these mycelia, it is advisable to treat the plant with benzimidazole and triatomic products, easily available on the market.

As far as the lower part is concerned, it would appear to be affected by branch drying. There are no specific active ingredients to eradicate this disease, but treatments can be carried out with products with a long persistence (that is, they remain effective for a long period) which prevent the spread of the disease (eg Ziram and Zinab). Cut the affected branches, healing the wounds, and burn them. Remember to disinfect the scissors and tools used.

We inform you that from the next issue, on a monthly basis, we will publish a fact sheet on a fungal disease and a parasitic insect, starting right from the white sore. We also invite you to register on our mailing list, to keep up to date with the news of the site, and to use the online forum available to all our readers for further questions.
