Plants can be prone to fungal diseases, dangerous diseases affecting flower, horticultural, ornamental and fruit crops. The fungal diseases they appear as spots of different color and texture. The causes are attributable to high humidity, abundant irrigation and stagnation of water.
Fungal diseases, how to recognize and prevent them
The fungal diseases they attack our plants in a different way: some attack the leaves more, while others attack the stem or the root system.
Among the main diseases that attack the leaves of plants we find powdery mildew also known as white: it develops in spring and manifests itself on the upper part of the leaf with large whitish and powdery spots, like flour. The cause is attributable to irrigations done directly on the leaves. Powdery mildew causes discoloration, yellowing and subsequently the drying of the leaves. To avoid the spread of powdery mildew it is important to do a good prevention, avoiding exposing the plants to excessive humidity, avoiding direct irrigation on the leaves and distancing the plants well from each other to avoid water stagnation. If, on the other hand, the disease is now developing, it is necessary to intervene with specific products for sale in nurseries or consortia. There are also natural methods.
The fungal diseases that instead develop on the lower part of the stem is the sclerotinia which involves the browning and gradual rot of the affected parts. It manifests itself with dark spots called sclerotia which are capable of spreading through the soil and the seeds of the plant itself, thus making the disease very contagious.
To prevent it, it is necessary to avoid excessive humidity and promptly destroy the affected species to avoid contagion to healthy ones.
Other fungal disease Botrys cinerea is very insidious, better known as gray mold: it affects any part of the plant and adapts to any environmental condition,
It mainly affects flower crops, such as chrysanthemum, rose and cyclamen, of which it attacks and destroys above all the flowers, but some horticultural species, such as tomato and strawberry, and fruit ones, such as apple, are not free from it pear, peach and plum, and the vine of which it heavily attacks the bunches.
The high temperatures and excess humidity favor gray mold.
