If the glossy medlar suddenly does not look good, it may be due to a pest or disease. Then fast action is important to save the plant.In addition to frost damage, which leads to brown spots on the leaves of the glossy medlar, the plant can also form diseases. But even pests are not unknown. If your loquats in the garden are sickly or have altered leaves, then it is high time that you act. After all, you do not want your glossy medlar to die of the disease or the pest.
These diseases can occur
Two diseases are especially common in glossy medlar.
The diseases are caused by a fungus that damages the leaf structure:
In this fungal disease, gray spots form on the leaves. The apple scab is spreading relatively fast, so you need to act quickly. Cut off the affected parts of the plant completely. Do not put it on the compost, but burn it. The apple scab might otherwise spread in the garden. Alternatively, you can also dispose of the plant parts in the household waste. Then you should still spray the plant with a copper-containing spray (for example, available here). Follow the manufacturer's instructions.
If the gloss medlar is affected by the tint, black and red spots form on the leaves. You should then cut the leaves as a precaution unless you are sure that the spots are not brownish. Because the gloss medlar can also be attacked by a pest that leads to brown spots. To combat the fungus, spray the plant again with a medium containing copper sulphate.
This is not an isolated disease, but it still leads to brown spots on the leaves. As a remedy you only have to ensure the water supply in winter and water the plant regularly. Reading tip: Maintain the glossy medlar properly.
Pests on the gloss medlar
Parasites can also attack the glossy medlar. They can be partly combated with home remedies. Alternatively, there are also numerous control agents to buy in the trade.
Aphids usually settle on young shoots and their leaves. Since the lice do not get stuck, in the first step you can try to remove them with a sharp jet of water. Alternatively, funds based on soap and rapeseed oil help. The preparations do not harm beneficials. You can even make a preparation yourself. Simply add a little washing-up liquid and a little rapeseed oil in ten liters of water and sprinkle it extensively with the loquat.
If you would like to prevent the aphid infestation in advance, you can regularly spray the medlar with a broth of nettles (instructions here).
Feeding damage to the leaves indicates the weevil. Likewise, you can detect the infestation of larvae, which lead to damage to the root neck. Collect the beetles as quickly as possible. Nematodes, a substrate that you need to add to irrigation water, kill the larvae. It is available for example here.
That's why the leaves can fall off
Should your loquat lose primarily leaves, this indicates a wrong casting behavior or an incorrect earth condition. Check if the soil is too wet or if waterlogging has formed. In this case, you should mix the soil with humus to absorb the excess moisture. If the soil is dry, it also leads to leaf loss.
