Let’s see together how to immediately recognize the fungal disease of tomato. Here is the way to prevent it and prevent it from spreading: these are the signs.

Fungal disease

We are at the perfect time of year for growing our beloved tomatoes . Tomatoes are practically the basis of Mediterranean cuisine. Between salads, caprese, sauces and so on, they represent the most versatile and delicious food that nature could give us as a gift. There are dozens and dozens of different tomato varieties , and we can choose to grow the one we prefer most. Growing tomatoes is not easy at all: they are delicate fruits and very vulnerable to external attacks .

If we don’t take the right precautions during the cultivation phase, we shouldn’t be surprised if the result doesn’t satisfy us. In addition to thinking about the nourishment and irrigation of the plant, we must be careful of the diseases that some mushrooms could bring to our garden. They are not diseases harmful to humans, but they are harmful to our tomatoes and their integrity. Here’s how to prevent and recognize a fungal disease.

Tomato fungal disease: downy mildew

Some fungal diseases can completely wreak havoc on our entire garden. There are some diseases that develop very easily and are capable of destroying all tomato plantings. Among these is downy mildew. Tomato late blight is one of the most common, but also one of the most dangerous tomato diseases. This disease occurs directly in the seedlings, therefore prevention and protection must be implemented from the beginning. The cause is the fungus Phytophtora infestans . But how can we understand when this fungus invades our plantation?

To notice the symptoms of tomato blight, regular crop inspections are needed , and preventative protection is best. Prevention of the occurrence and spread of the disease is carried out by taking a comprehensive set of preventive actions and intervening very often. Pseudofungus Phytophthora infestans causes damage to all parts of plants . Here’s how to recognize it.

When our tomatoes are in danger

The extremely humid climate is ideal for the onset and subsequent proliferation and spread of the disease. The first symptoms of the disease appear when the plants are grown in the temperature range from 18 to 21 degrees and a high relative humidity of 60-90%. The first symptoms of the disease are related to the appearance of light green or whitish spots on the leaves of the plants, first on the tips of the leaves.

After a certain period and unfavorable climatic conditions, the spots extend to the entire leaf mass . It appears on the stem in the form of elliptical spots that change shade, from the initial bright state to a darker color. They appear ring-shaped , which causes the flow of nutrients to be blocked and the plants to eventually dry out. The fruits are affected by dark spots which lead to rotting and decay of both the fruit and the plant. We can conclude that downy mildew is dangerous in all vegetation periods . It is necessary to protect the plants beforehand, especially before the long rainy period. High evaporation of moisture from the soil is more suitable for the development of this disease.
