The plum tree is a very present species in orchards and in amateur plum trees, with its countless varieties divided into two large groups: european plums (plums) and Sino-Japanese plums (plums themselves). This tree belongs to the group of stone fruits with peaches, almonds, apricots and cherries and usually offers an abundant production also in organic farming, which we strongly recommend.
The important thing for a good harvest is the constant observation of plant health , to be able to intervene quickly, at the first manifestation of the symptoms of diseases or attacks of parasites. Like the rest of the stone fruits, in fact, the plum can also be affected by pathologies of all kinds, as well as by harmful insects, but fortunately we can resort to solutions with low environmental impact.
In this article we describe the main diseases of plums , learn to recognize them and indicate some preventive and curative strategies always with a view to ecological biological defense. You can also consult the guide to defending plum trees against insects.
To combat diseases of plum trees and plum trees, like all other fruit plants, prevention should focus on prevention first , which already occurs during the design phase of the power plant, because certain choices at this time will have important consequences. Therefore, it is recommended:
- Give preference to resistant varieties or at least tolerant, to the most common adversities;
- Adopt large planting rooms , without getting caught up in the desire to put a lot of plants in an insufficient space, thinking then of containing them with pruning. The plants, in fact, must be able to express their vigour, and even if the grafted specimens are chosen on less vigorous rootstocks, they should be left with the necessary space so that the air can always circulate, an essential condition for limiting pathogen attacks. .
Once the installation is complete, there is other important preventive measures What to pay attention to:
- Watering under the canopy , preferably with a drip wing system, which distributes the water only on the ground and not on the aerial part. In fact, pathogenic fungi are favored by atmospheric humidity and water that is impermeable to foliage.
- Do not over fertilize : Over-fertilized plants are aesthetically beautiful because they are very green and lush, but in reality they are weaker, because their tissues are less resistant to the penetration of the pathogen and to the bites of certain insects.
- prune regularly always without exaggerating with the cuts, but ensuring good lighting and good ventilation of the foliage.
