- Cercosporosis spreads in the form of small reddish dots. The foliage dries, in rainy weather it is complemented by a black bloom - fungal spores. It is better to save honeysuckle with Fundazol.
- Powdery mildew - white bloom begins to cover leaf plates, shoots. Then black spots appear. The twigs are bent, the foliage becomes brown, dries. It is important to remove dry foliage, shoots, any plant residues in a timely manner. Of the preparations suitable for processing "Tiovit", "Chistotsvet", "Raek".
- Frostbreakers. Sometimes after wintering, cracks appear on the branches. A fungal infection settles in them. It provokes drying of the shoots. Therefore, in the spring, the shrub is carefully examined and sanitary pruning is carried out, removing branches with cracks. After that, the honeysuckle is sprayed with a solution of Bordeaux liquid.

Honeysuckle viruses
There is no cure for viruses as such. Therefore, the only way to fight is pruning and burning the affected branches, and sometimes the entire plant.
The shrub is most often affected by such viral diseases:
- Foliage mottling. This virus is carried by nematodes. With its development, the foliage of the honeysuckle is covered with dots, spots, a pattern consisting of arcs.
- Mosaic of rezuha. Such a virus is harmful not only for honeysuckle, but also for many other fruit and berry crops. It enters the area with infected planting material, and it is also carried by nematodes. Side shoots begin to grow on the bushes in large quantities. At the same time, the plant does not have strength for foliage and normal growth.
