Of course, all the ailments affected by plum trees can be avoided. The secret of success is the correct prevention, protection of the tree and the fruits themselves, as well as a prudent approach to caring for the health of the whole tree. In such a case, the chance of an outbreak of a plum disease or a possible attack of unwanted pests is minimal. However, it is necessary to know how individual diseases manifest themselves, what symptoms they cause and how to defend against them as effectively as possible.
3 most common plum diseases
Red speckled leaves
The most common disease that can affect plums is the fungus known as Polytime rubrum. She waits for her opportunity during the winter, when she is hidden so that she can spread the spreading infection on the plum leaves in the spring.
A batch of plums
The reason for the rupture of the plum brandy, in contrast to the red spot of the leaves, is the virus. It is one of the worst viral diseases, which affects not only plums, but also many other fruit trees, from which the virus can spread to plums.
As with red leaf spot, the fungus is usually the cause of the disease. However, its goal is not the leaves, but the fruits themselves. They damage them gradually, first changing color, then deforming their shape until they are completely degraded.
Other known diseases of plums
Plums in our garden can also suffer from other diseases. Although these are not as common as in the above cases, their occurrence can also result in crop destruction or damage to the tree itself.
Dry spotting of leaves
Lesser-known disease only affects plum leaves. Small brown-red spots, which are initially only about 5 mm in size, alert us to its spread. However, with a more aggressive course of the disease, they can spread relatively quickly, which would lead to an early fall of the affected leaves.
Monosomies of pucks and fruits
Among the diseases of plums caused by dangerous fungi are also the so-called meiosis of pucks and fruits. The fungus responsible for it is most successful in periods of frequent weather variability, ideally at temperatures from about 10 to 12 ° C. The consequence of its tanning can also be the emergence of the so-called manila plum rot.
Magnalium plum rot
An inconspicuous, but even more insidious disease always arises as a secondary consequence of the tanning of fungi or pests. While it sometimes occurs as a result of an outbreak of moniliasis, other times it may be due to plum worms, which is a breeding ground for this type of rot.
The 3 most common pests of plums
Wrappers belong to a genus that does mischief on several types of fruit trees. The plum coater focuses on plums, whose larvae cause plum worms. The consequence of worming is not only damage to the fruit, but also the above-mentioned manilla rot, which completely degrades the fruit.
Spider mites also attack several types of fruit trees, including plums. They are a risk to the health of trees, mainly due to extremely fast reproduction, which results in leaf damage. After their attacks, small spots form on them, which gradually devalue the entire leaf.
Aphids on plums
The presence of common aphids that remain on the plum is not dangerous for the tree. If the aphids are not overgrown, they are not dangerous for the fruits themselves. They will just be annoying and they will suck some juice from some plums. They can’t do much damage also because they are food for ladybirds, which reduce them in such a natural way.
