Despite the fact that raspberries are a fairly unpretentious plant that tolerates frosts and can actively develop in any soil, it is susceptible to attack by pests and attack of diseases. To combat this scourge was simpler, you should know what diseases and pests in the pictures are characteristic for this culture. After all, the enemy is easier to defeat if you know him by sight!
Most common diseases
There are several diseases that can affect a raspberry bush no matter which grade was selected and planted.
Gray rot
A disease that is caused by a fungus. A disease can attack all parts of a plant, but the most frequent places of its manifestation are fruits and flowers. Recognizing the disease is quite simple: the affected areas become gray.
Attention! Fruits affected by gray rot should not be eaten!
The causes of the disease include warm, humid weather.
White spotting
A disease that also relates to fungal diseases. White spotting does not touch the fruits, but only the stems and leaves of the plant are affected. Visually recognizing it is very simple: small spots of dark color appear on the affected areas, sometimes with a brown tint. Over time, the spots begin to lighten, and if raspberries are not treated, its affected leaves will begin to dry out and fall off.

Root cancer
Visually detecting the disease is very difficult, since it affects the roots of the plant. While the disease is already progressing, the growth of raspberries is slowing, and the berries are losing their taste. Most often, the disease can be detected during a transplant, when the obvious symptoms of the disease do not yet manifest themselves.
Bushiness
A disease that also has a second name is sprouting. Visually recognizing the disease is not difficult: a lot of thin shoots with small leaves are formed around the rhizome. The causes of the development of the disease include a virus that spreads along with the juice of the plant.
Most common pests
In addition to diseases, raspberries can be attacked by pests, which can be studied by description, pictures and photos.
Raspberry and strawberry weevil
A tiny bug with a long nose harms not only raspberries, but also other berry crops even before the fruits ripen. The adult female beetle lays eggs in the peduncle, which is why the flowers do not bloom as a result.
Raspberry beetle
The most common pest on raspberries is yellow-brown in color and has a body length of 4 millimeters. They are able to destroy the whole berry or affect the size of the fruit, making it several times smaller.
Raspberry glass
The pest is visually similar to a butterfly with the body and color of a bee or wasp. The danger is not an adult, but its larvae, which cut the shoot of the plant to the root. The egg-laying period in the glass-cases falls in the middle of summer. A pest attack can either significantly reduce yield, or raspberry bushes can break at the base due to gnawed stems.
If you look at the diseases and pests in the pictures, then they obviously do not cause sympathy, not to mention the damage they cause to the culture. Therefore, they should be actively fought and prevented.
