Tomato fungus disease: downy mildew
Some fungal diseases can completely devastate our entire garden. There are some diseases that develop very easily and are capable of destroying all tomato plantations. This also includes downy mildew. Tomato blight is one of the most common tomato diseases, but also one of the most dangerous. This disease occurs directly in seedlings, so prevention and protection must be implemented early on. The cause is the fungus Phytophtora infestans. But how can we know when this fungus is invading our plantation?
To notice the symptoms of tomato rot, it is necessary to inspect the crop regularly, and preventive protection is the most appropriate. The prevention of the onset and spread of the disease is carried out through a comprehensive set of preventive measures and very frequent intervention. The pseudofungus Phytophthora infestans damages all parts of the plant. Here’s how to spot it.
When Our Tomatoes Are in Danger
The extremely humid climate is ideal for outbreak and subsequent reproduction and spread of the disease. The first symptoms of the disease appear when plants are grown in the temperature range of 18-21 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 of time and unfavorable weather conditions, the spots spread to the entire leaf mass. It appears on the stem in the form of elliptical spots that change hue, from the initial light state to a darker color. They appear in a ring shape, causing the flow of nutrients to be blocked and eventually the plants to dry out. The fruits are affected by dark spots, which cause rot and decay of both the fruit and the plant. From this it can be concluded that downy mildew is dangerousin all growing seasons. It is necessary to protect the plants beforehand, especially from the long rainy season. High evaporation of soil moisture is more suitable for the development of this disease.
