The first symptoms of the potato hand appear on the aerial components of the plant, but also on the tubers, in May and June, very often before the plant flourishes. The symptoms that should worry are the yellow spots with a widespread side dish appeared on the surface of the leaves. Subsequently, the spots will increase and become brown, then black, surrounded by a yellow and irregular border. It is very very possible to see a soft white flush that will form on the outskirts of the spots.

On the stem of the potato touched by the hand you will be able to see elongated black spots, which can be extended throughout its surface. The drying of the plant, from that moment on, is inevitable.

The potato tubers will also be affected by the hand, which will form brown or blue spots in immersed areas.

The hand of the screws

The hand of the screws can be seen on all the underground components of the plant. The leaves of the screws are often affected and the attack on them will be visible through spots that reach very large surfaces of the plant. Depending on the stage of the disease, the hand can transform the appearance of the leaves more or less.

If the screw has been touched by the hand, spring you will be able to see yellow spots with fat appearance, which can be increased or multiplied, depending on the humidity in the air. If this is very high, you will most likely notice the presence of a gray white hands next to the stains before.

The hand of the tomatoes (tomatoes)

And tomatoes can suffer from hand. The symptoms of the installation of this disease in the case of tomatoes begin with the attack of the leaves from the base of the plant, on which small circular points will appear. Shortly thereafter, if measures are not taken to fight the mana, the disease can extend to the other leaves, stems, flowers or even fruits, being able to influence the entire tomato harvest.

Initially, the stains that will be installed will have a green color. Subsequently, they will turn into brown points. In the case of intense attacks, the disease also manifests itself on the stems, in the form of small brown spots, which surround the stem on large portions.
