The key to successful gardening is strong and healthy seedlings.
But what to do if you encounter the unexpected appearance of black spots on young plants? The answer to this question was given by the expert of the online publication "BelNovosti", scientist-agronomist, landscape designer Anastasia Kovrizhnykh .
One of the possible reasons for the appearance of such “defects” may be infection with the bacterium Xanthomonas campestris pv. vesicatoria, which causes black bacterial spot.
This bacterium can be transmitted through seeds and plant debris.
The main symptoms of bacterial spot
1. Small water-soaked spots appear on the leaves, which become darker over time.
2. The spots may merge to form larger marks.
3. If the infestation is severe, the leaves may become deformed and die.
How to combat bacterial spot
To combat bacterial spot, preventive measures must be taken. It is important to select plants that are resistant to spot. It is also necessary to carefully treat the seeds and soil before sowing.
If you notice signs of infection, you must immediately remove the affected parts of the plant.
