What is black spotting and why is it so dangerous?
Plants in the garden are exposed not only to pest attacks, but can also be infected with diseases. Most often they occur, which very quickly spread through many plants. Mushroom spores along with the wind move and infect more plants in the garden. Moisture and heat promotes fungal diseases. It is in such conditions that they spread the fastest. Black spotting is. It is caused by Diplocarpon Rosae.
Black spotness is manifested by black spots appearing on the leaves. A characteristic feature of black spotted are yellow borders around black spots. Infected leaves break and fall. The disease weakens the whole bush and leads to its dying. Black spotting develops in a warm and humid environment. Its source can be old, corrupt leaves lying on the ground. Gardeners indicate that regular removal of old leaves and inflorescences is necessary to preserve healthy bushes.
A neighbor of the gardener recommended me homemade spraying for black spotting. Removes mushroom spores
This is a disease that should be combated. If it has not yet infected the whole bush, natural spraying will come to the rescue. Spraying with Miedzian is recommended to fight black spottedness. It helps both in the fight against the disease itself and works preventively. The Polish Rose Society recommends that the concentration of copper is 0.3 percent, i.e. 30g per 10 liters of water. A friend of the gardener showed me that baking soda is also effective in the fight against fungal diseases. It is famous for its fungicidal properties, and is also safe for plants. Just mix 1 tablespoon of baking soda in 1 liter of water and spray the rose shrub thoroughly. You should not avoid any places, spraying should be applied from above to the bottom. Do not forget about the inside of the leaves. Use the spraying of baking soda once a week until you notice that the disease goes back.
In the event that the disease is very developed, home methods may not be enough and you need to reach for more advanced methods. Fungicides are recommended to fight black spottitude, including preparations containing tebuconazole. It is a fungicide that is absorbed into plants and inside protects against attacks of fungal diseases.
