Mushroom infection at the Yucca Palm - and what you can do about it
Fungal infections can usually be detected on coverings on the leaves or sometimes also on shoots, on cotton-like coverings, partial wilting or also on leaf spots and / or pustules.
The most common fungal diseases of yucca palms
There are many fungicidal agents, but you can prevent them from attacking with the following measures:
Fungal diseases are usually caused by care errors, which is why a species-appropriate care is considered the best prevention. If your Yucca ever shows signs, the following fungal diseases are among the most common.
root rot
The root rot is always due to too wet substrate, as a result of which fungi settle on the roots and decompose them. Infestation occurs when you notice muddy and putrid areas at the roots, at the root neck and in the lower trunk area. As the plants can no longer be properly cared for, they wither. Afflicted yuccas can be rescued, you still have to cut off healthy plant parts and re-rooted.
Stem rot
If the trunk becomes soft and / or hollow, then the root rot has already passed into the above-ground parts of the plant. In addition to the rotten roots and the soft trunk appear brown to blackish, often sunken and foul spots on the leaves and shoots. This is a sign that the fungal pathogens are spreading and the yucca is entering. A rescue is partially possible, see root rot.
wilt disease
If the yucca suddenly and without reason leaves the leaves hanging and wilts, then in rare cases, the dreaded wilting disease may be behind it. Since the roots seem to be healthy, excessive moisture is not the cause in this case. Instead, the causative fungus comes from the infected earth, penetrates from there into the conduction paths and clogs them. Preventively use only germ-free soil and remove affected parts immediately and generously.
sooty mold
If the leaves of the Yucca show a blackish surface, it is most likely a black-throated fungus. This is always accompanied by an infestation by leafy or other plant lice, as he settles on their honeydew called precipitates. Wipe off the honeydew and mushroom topping with a damp cloth and fight the pests.
leaf spot
Various fungi cause round spots on the leaves, which often appear in a different ring-shaped color and are often surrounded by a yellowish yard. These patches gradually increase and can sometimes spread over the whole leaf. The causing fungi are mainly spread by drafts or improper watering - for example, by the leaves are moistened. Do not wet the yucca leaves when casting and avoid drafts. Affected leaves should always be removed.
Tips
A white coating on the leaves of the yucca may be an indication of an infection with mildew - or an infection with gall mites, which cause a very similar damage pattern.
