Fungus attack on the rock pear - what to do?
The rock pears are basically quite robust and undemanding plants. Unfortunately, there are quite often problems with fungal diseases that make repeated control measures necessary.
Clearly recognize fungal diseases
If there are signs of a fungal infection on your pear in the garden, you should first rule out other causes for the abnormalities before taking appropriate countermeasures.For changes in the leaf color, there may finally be different reasons for the rock pear:
In the various species of the rock pear it can sometimes happen that cold snaps or dry phases in the summer provide for premature leaf shedding. In this case, no special care measures are to be taken. Individual leaves with red color may also be a sign of infection with fire blight. But this is not a fungal disease, but a plant disease caused by bacteria.
Detect powdery mildew and fight it
For the appearance of powdery mildew (mushroom Podosphaera spec.) On rock pear various factors such as the location, the planted variety, the weather or even the vicinity of other susceptible to mildew plants may play a role. The powdery mildew can be recognized as a white coating on the leaves, with initially small, white dots on the top of the sheet arise, which then spread. The leaves roll in the episode and are dropped in a timely manner. This is a so-called "fair-weather mushroom", which can not be kept in check by regular cutting and a well-ventilated plant structure. However, every outbreak should be contained by removing the affected shoots as quickly as possible and disposing of them via the bio-waste.
Prevention is more effective than treatment
Although clusters of pears do not necessarily die from mildew, it suffers not only from the appearance of the plants but also from the usability of the fruit that is actually edible. If powdery mildew occurs in a garden even before planting the rock pear, more resistant wild forms should be preferred to the cultivars. Fertilization with a low nitrogen content, like a well-dosed, regular cut, can boost overall plant health. At the first signs of powdery mildew, the affected shoots and buds should be cut out in the infested area over a large area, as the fungus overwinters in these. From spring onwards, every 7 to 14 days should be injected with a 1: 5 mixture of milk and water as a precaution from the new shoot.
Tips
If clusters of pears repeatedly suffer from fungal attack over the years and are treated with appropriate fungicides, then the selected preparations should be changed regularly. This will help prevent the development of fungicide resistance and ensure its effectiveness.
