At a time when mass sowing of paradi\u017enika, peppers, chilies and other vegetables begins, many gardeners encounter the same problem.<\/p>\n\n\n\n

The seedlings germinate beautifully, then suddenly lie down and die.<\/p>\n\n\n\n

We call this phenomenon seedling drop<\/strong>.<\/p>\n\n\n\n

It is one of the most common diseases of young plants, which can destroy an entire seed tray in a few days.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

What is seedling blight?<\/h2>\n\n\n\n

Seedling blight is a disease that attacks very young plants, usually in the first weeks after germination.<\/p>\n\n\n\n

Where the stem emerges from the soil, the tissue softens and darkens. The plant narrows at this point, loses support and topples over.<\/p>\n\n\n\n

The seedling then dies very quickly.<\/p>\n\n\n\n

The disease often appears suddenly, even if the plants initially appear healthy.<\/p>\n\n\n\n

What causes seedling drop?<\/h2>\n\n\n\n

Powdery mildew is caused by various fungi and fungus-like organisms in the soil, the most common of which are:<\/p>\n\n\n\n

\u2013 Pythium<\/em>
\u2013 Rhizoctonia<\/em>
\u2013 Fusarium<\/em>
\u2013 Phytophthora<\/em><\/p>\n\n\n\n

These organisms are often already present in the soil or substrate.<\/p>\n\n\n\n

Problems arise mainly when the conditions for their development are ideal.<\/p>\n\n\n\n

When does epilepsy most often occur?<\/h2>\n\n\n\n

It most often occurs when several factors are present at the same time:<\/p>\n\n\n\n

Too much moisture<\/strong>
Excessive watering or poorly drained substrate.<\/p>\n\n\n\n

Poor ventilation<\/strong>
Closed mini greenhouses or insufficient air circulation.<\/p>\n\n\n\n

Low temperatures<\/strong>
Cold soil and slow seedling growth.<\/p>\n\n\n\n

Too dense sowing<\/strong>
The seedlings are growing too close together and shading each other.<\/p>\n\n\n\n

Heavy or contaminated soil<\/strong>
Using garden soil instead of a quality substrate.<\/p>\n\n\n\n

How to recognize seedling blight?<\/h2>\n\n\n\n

The most common signs:<\/p>\n\n\n\n

\u2013 the seedling suddenly lies down
\u2013 the stem near the ground becomes darker and thinner
\u2013 the tissue becomes soft or watery
\u2013 the plant breaks or collapses onto the substrate<\/p>\n\n\n\n

Once the disease appears, it can spread very quickly to neighboring seedlings.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

How to prevent seedling drop?<\/h2>\n\n\n\n

Prevention is much easier than solving a problem.<\/p>\n\n\n\n

1. Use a quality substrate<\/h3>\n\n\n\n

Use a light, airy seedling substrate for sowing. This substrate drains water better and reduces the chance of disease development.<\/p>\n\n\n\n

2. Water moderately<\/h3>\n\n\n\n

The substrate should be slightly moist, not wet.
Too much water is the most common cause of problems.<\/p>\n\n\n\n

3. Provide ventilation<\/h3>\n\n\n\n

Open mini greenhouses or covers regularly. Air circulation significantly reduces disease development.<\/p>\n\n\n\n

4. Seedlings should have enough light<\/h3>\n\n\n\n

Strong, fast-growing seedlings are less susceptible to disease.<\/p>\n\n\n\n

5. Don't sow too thickly<\/h3>\n\n\n\n

If the seedling is too small in a space, moisture is retained for a longer time and the conditions for disease development are better.<\/p>\n\n\n\n
