Diseases of the leaves of fruit trees

There are many pests, fungi, viruses or infections that affect the leaf of the fruit tree and are recognized by horticulturists as diseases of the leaves of fruit trees.

 

Most common leaf diseases

Stone and seed fruit trees are affected by different diseases that we will see below:

1) Pear rust

Infection that attacks both leaves and fruits. It is characterized by the appearance of yellow and reddish spots on the leaf and black corpuscles on the fruit.

The affected parts are not cured but it is important to burn and remove them so that the infection does not spread again every year.

2) Lead disease

Trees such as plum and peach trees are prone to developing this infection. There is no chemical treatment to solve this disease but it is easy to detect due to the appearance of silver colors on the leaves, which usually weaken, wither and fall. The entire tree can die due to this infection, making it one of the most potent known.

3) Roña or mottling of apples and pears

It is considered the most serious infection of pome fruit trees.

It is a type of fungus that produces the appearance of almost black brown spots on leaves and fruits but especially in the latter. This is one of the most common diseases of the leaves of fruit trees.

Depending on the flowering stage, a different prevention or elimination method will be used.

4) Mottled loquat

The clearest symptoms are the appearance of parched spots on the fruit itself. It is similar to the mottling of apples and pears above.

It is best to destroy the affected parts with fire.

5) Peach leprosy

We are facing a very powerful type of fungus that affects plantations of peaches and nectarines. It is very easy to detect thanks to the wrinkled and red leaf that begins to appear during the spring.

After a month, the leaves will fall and a general weakening will be noticed in the tree that will produce a bad fruiting and that can even reach death.

There are more diseases of the leaves of fruit trees but, in general, the 5 named are the most common in Spain.
