One problem that arises when growing tomatoes is late blight. This harmful microorganism prefers to attack nightshade plants and infects them in a short time.
The most common place of their appearance is in overburdened plantations, as well as during sudden fluctuations in temperature.
Diseased plants can be recognized by the characteristic spots on the lower leaves. First they appear, then they dry up and fall off. The tomatoes become dark and covered in black spots. What’s especially dangerous is that this fungus can persist in soil, on tools, and even on internal greenhouse surfaces.
When the disease first begins to spread, you can avoid chemicals and use time-tested traditional methods.
Here are some recipes to protect against late blight:
- 10 liters. water, 1 liter. kefir and 20 drops of iodine solution. After a few hours, treat the plants.
- 10 liters. water, 20 g of soap, 3 tablespoons. tablespoons of soda. Spray weekly.
- 1 liter. whey, 35 g of dry yeast. After five hours, start spraying at 10-day intervals.
- Piercing the stems with copper wire to a height of 10 cm can also protect tomatoes from diseases caused by copper ions. This method is suitable for healthy and strong plants.
