Juurimätään

Juurimätään, often translated as root rot, is a general term for a condition affecting plants where their root systems decay. This decay is typically caused by pathogenic fungi or oomycetes, although bacterial infections can also be a factor. These microorganisms thrive in moist, poorly drained soil conditions, creating an environment where plant roots are more susceptible to infection.

Symptoms of juurimätään can vary depending on the plant species and the specific pathogen involved. However, common signs include stunted growth, yellowing of leaves, wilting even when the soil is adequately moist, and in severe cases, complete plant collapse. Upon examination, infected roots may appear brown or black, mushy, and may easily break apart.

Several factors contribute to the development of juurimätään. Overwatering is a primary cause, as it leads to waterlogged soil that deprives roots of oxygen and creates favorable conditions for pathogens. Poor soil drainage, using pots without drainage holes, and planting at excessive depths can also increase risk. Environmental stress, such as extreme temperatures or nutrient deficiencies, can weaken plants, making them more vulnerable.

Management and prevention strategies focus on addressing the underlying causes. Ensuring proper soil drainage, avoiding overwatering, and using well-draining potting mixes are crucial. For susceptible plants, employing fungicides or biological control agents may be considered. Removing and destroying infected plants, along with sterilizing tools, can help prevent the spread of pathogens.
