Hi everyone! Welcome or welcome back to Green Italy! I'm Claudio, an agricultural entrepreneur, and in this channel I share my experience in growing vegetables. Today we will talk about fungal diseases, in particular about late blight of tomatoes. We will find out what it is, how to recognize it and above all how to fight it. So, without wasting any time, let's get started right away!
In the current period, temperatures, rains and high humidity pose a threat to crops, especially tomatoes. One of the main problems that occurs in these conditions is downy mildew, a fungal disease that can cause serious damage to crops. Therefore, it is essential to understand what downy mildew is, how to recognize it and, above all, how to fight it.
Downy mildew is a fungal disease that affects tomatoes, compromising their growth and production. Ideal conditions for late blight to develop include temperatures between 16 and 20 degrees Celsius, high humidity, and little light. Unfortunately, these factors are often present during periods of cooler temperatures, rainfall and high humidity, putting tomato crops at risk.
To recognize late blight, you need to carefully monitor the plants, especially the leaves. Distinctive signs of the disease include the appearance of yellow spots on the leaves, which subsequently lead to necrosis and drying of the leaves. Downy mildew can also affect the stem of plants, causing black spots that can spread and affect the entire plant. Furthermore, green and underripe fruits may have abnormal spots that lead to the formation of necrosis.
Prevention is essential to fight downy mildew. It is advisable to respect the planting layout, i.e. the adequate distance between the plants, in order to avoid the formation of shaded areas which favor the proliferation of fungi. Another important aspect is the defemming, or rather the removal of the lateral shoots of the tomato plants to favor air circulation and reduce humidity. This practice helps prevent the onset of fungal diseases.
In the preventive fight against late blight, products based on copper or potassium bicarbonate can be used. Copper has fungicidal properties and is often used, but it is important to use it in moderation to avoid excessive accumulation of copper in the soil and negative impact on soil microflora. Potassium bicarbonate, on the other hand, has been shown to be effective in preventing downy mildew. It works by modifying the pH of the leaves, creating an unfavorable environment for the growth of fungi, absorbing excess humidity and damaging the cellular structures of pathogenic fungi. Furthermore, it stimulates the plants' immune defenses, helping to counteract the infection.
It is important to underline that, in addition to preventive measures and treatments, it is essential to maintain proper soil and plant management. This includes good irrigation, which supplies water in a balanced way without creating stagnation or excessive humidity. In addition, it is essential to promptly remove infected plants or parts affected by downy mildew to avoid the spread of the disease.
In conclusion, downy mildew poses a threat to tomato crops, especially in conditions of cool temperatures, rains and high humidity. However, by adopting preventive measures such as respecting the planting layout, defemming and the use of copper or potassium bicarbonate-based products, it is possible to reduce the risk of infection and protect the crops.
