Fungal infections cause spotted leaves
Basil does not spare basil, one of the largest genera of mushroom mushrooms called Septoria. The spores cause brown necrosis on the leaves that spoil our appetite. In damp weather, the damage appears from June in the form of small, spreading spots. Ultimately, the leaves will dry up and fall off. Effective control agents are not yet known. How to prevent infection:
- Cut back affected shoots except for one pair of eyes
- Plant the basil at an airy distance
- do not fertilize too nitrogen-stressed
- Avoid locations with little light
- Correctly interpret and treat yellow leaves on basil
- These pests target basil
- These diseases threaten basil - symptoms and control
First and foremost, a location protected from rain provides effective prevention against infestation by Septoria spores. Smart hobby gardeners therefore put basil in the garden with their tomato plants under a rain roof.
Aphids have the alfalfa mosaic virus in their luggage
The symptoms of the widespread virus infection are manifested in the form of mosaic-like discoloration on the leaves. In addition, deformations and compressions develop on the foliage of the royal herb. In the herb garden, aphids are usually the carriers of this devastating plant disease. No cure is known. To prevent the viruses from spreading further in the garden, the infected basil should be destroyed immediately.
As a preventive measure, knowledgeable hobby gardeners take consistent action against aphids. In the course of intensive research, thrips were also suspected of introducing the mosaic virus, so that these harmful insects should be included in the control. Since the viruses are sometimes transmitted through infected seeds, we recommend using only certified quality goods from specialist retailers.
Tips & Tricks
It doesn't always have to be a disease that stains basil leaves. Incorrect pouring behavior is one of the most common causes of this damage. Tender royal herb does not want to be watered from above. Even when sprayed, the herb plant reacts with brown spots. Therefore, always pour directly at the root area.
