Plant diseases, how to recognize them

In this article we will deal with the topic plant diseases, as the period approaches when our green spaces are most exposed to disease. In fact, between spring and summer, if we do not pay particular attention to our garden, the plants could get sick and in the worst cases even die, frustrating all the efforts made previously. In this regard, here's how to prevent and recognizeplant diseases following some important indications.

The plant diseases they are mainly caused by fungi, which attack both ornamental and garden plants, causing unsightly spots on the leaves: they are also visible to the naked eye. Between plant diseases more widespread are the "white mal" and "gray mold".

Plant diseases, badly white
If on the leaves of the plants we find a whitish and floury patina that forms the typical "dust" on the leaf, it means that the plant has been attacked by powdery mildew, more commonly known as "bad white". It is a fungus that finds fertile ground when there is a humid climate and a temperature compatible with its needs: around 20-25 degrees. It can infect both leaves and flowers causing them to fall rapidly. When we are faced with this problem, that is, as soon as the typical spots on the leaves are highlighted, it is good to intervene immediately, preferably resorting to natural remedies that are as effective as shelf preparations. The operation consists in preparing a decoction of horsetail to apply on the leaves every day, it will disappear soon in the morning.

Plant diseases, white mold
If on the plant there is a whitish-gray hair and a softening of the parts that support the flowers and leaves, followed by their rapid withering, it means that the plant has been attacked by botrytis, also called "white mold". It generally attacks the weakest plants, preferably herbaceous (cyclamen, petunias, violets), but also fat. To fight the disease it is necessary to eliminate the causes of the spread of the fungus, represented by the high humidity. For example, we can ventilate the greenhouse more frequently, if your plants are there, or thin them out by increasing the space between one plant and another. If you want to intervene once the infection has taken place, you will need to remove the plants that have spots on the leaves from the others and cut the parts affected by the fungus. Once this is done, a propolis-based decoction can be sprayed by repeating the operation after a week. For many of these diseases, i pesticides,
