vine diseases

When you have a vine, you would like it to at least go through problems that prevent it from developing well. In other words, that you will face the diseases of the vine.

Therefore, we are going to give you a make a list of them in order to know which ones there are, what they consist of and the possible treatments that we found them. I’m sure it will serve as a guide.



It is one of the most common grapevine diseases in many regions. It is characterized above all because You will see a series of pale green spots begin to form on the upper side of the leaves. In addition to them, a mold will also appear on the underside.

If you don’t realize it at first, you will later because these leaves begin to dry up and become brittle, so much so that touching them or squeezing them a little will cause them to fall apart in your hand. Of course, they will fall, and the fruit will eventually rot.

To cure it, it is better remove all dead leaves or that they have this aspect to prevent the fungus attacking it from surviving. It is also advisable to use antifungal or liquid copper or Bordeaux mixture to avoid this problem.

vine powdery mildew

Another disease to consider is that of this fungus. It is characterized by the manufacture of the leaves have whitish spots, but it doesn’t stop there. Also fruits and even shoots can have it.

To grow, the fungus needs moisture, but this does not exactly mean that it can catch it in winter, but rather affects it in spring, with the typical rains of this season.

Now, what do we do with this problem? In principle, you would have two ways of acting:

  • That of prevention, what can be done fertilize and water the soil well to prevent the appearance of the fungus (because, although it appears with humidity, irrigation is not a factor in its appearance).
  • A witness, when the disease is already present on the vine. In this case, something that works really well is sulfur. If you fumigate with sulfur, you can stop the progress of the fungus and reduce it until it disappears. Once this is done, you should check that these fumigations should be applied at least four times throughout the season (or year) to prevent it from attacking you again.

vine rust

Rust is one of the most important diseases of the vine, so much so that it can seriously affect fruit production.

It is characterized by appearance on the leaves of a few red dots, specifically in the bundle of these. This causes them to spread little by little and eventually discards the leaf which will be contaminated.

In principle, the fungus attacks in spring and summer, because it needs a temperature above 24°C and high humidity.

To fight it, the first thing might be a emergency pruning so that the vine can have a stronger solar incidence, especially in the parts where the fungus is found. If you do this, you might stop the problem.


Also known as Eutipia, it is one of the most problematic diseases of the vine, and so far less known about it, since it appeared not so long ago.

This fungus is able to attack the whole plant, especially the green organs. This means that the plant cannot produce shoots or clusters, let alone leaves. In fact, it will start to have necrotic areas all over its stem.

As for the treatment, the first thing to do is prune and burn all areas that are in this situation. Pruning wounds should be covered with carbendazim paste or methyl thiophanate or triadimefon paste.


Another of the names by which it is known is gray rot of grapes, and it is that the part that this fungus affects is the bunches of grapes. More precisely, those that are almost ripe, which causes the whole bunch to be covered with a grayish coat that dries it out. Moreover, it is dangerous because, if this cluster has contacts with others, they will also be affected, and could compromise the production of this plant (or several).

To treat it, it is preferable to use products that prevent the problem because if it is reached, fighting him is hard enough. Regarding prevention, it would be good to use Benomyl, Folpet, Chlortalonil… in various treatments.

One of the diseases of the vine that directly affects the wood is this. It is produced by a fungus and usually appears more commonly in the old vines.

It is characterized by causing white to yellow color in the wood area, but although it may look almost harmless, it actually causes wood to rot; it turns white, then white and finally fluffy.

As for the leaves, when the stem and branches are affected, they begin to take on a chlorotic tone and wilt rapidly. Also the grapes usually appear spots.

To fight against this disease, the best thing to do is uproot this vine and burn it, because there is no effective treatment to eliminate the fungus. However, it can be avoided.

If the disease is not widespread, you can try to make a cut and apply, 4 days later, a protector on the wounds to be disinfected with 50% water and another 50% alcohol.

black feet

You may not have heard it by this name, but root rot will sound familiar. It is a fungus that mainly affects the youngest vines and that in a few days, even weeks, is able to eliminate them.

Symptoms that can alert you to this problem are the appearance of “white fans” in the root bark, which quickly turn brown.

To cure it, it is better remove this wood which is infected and burn it. In addition, a mixture of phenolic emulsion and 2% formaldehyde should be applied. Along with this (which applies to the soil), fumigation with fungal phytofortifier is good for the vine.

As you can see, many vine diseases can occur. There are plenty of others you should consider as well, but we’ve focused mainly on the most common ones. Have you experienced any of these or others? How did you solve it?
