Raspberry is one of the most unpretentious fruit shrubs, which gives a high yield, rich in vitamins from year to year. In order for the plant to actively develop and bear fruit, the rules of agricultural technology are observed. One of the most important is protecting raspberries from diseases and pests.
The most common diseases
Raspberries are susceptible to various fungal and infectious diseases. Determine the type by external characteristics:
- leaf color;
- the state of the shoots.
The most common are the following:
- curliness;
- root rot;
- anthracnose;
- verticillary wilting;
- mosaic;
- rust;
- purple spotting;
- gray rot;
- septoria.
Mosaic and curl are viral diseases that cannot be treated. As soon as the first signs were found, such plants are removed, and the land where it grew is disinfected. The bush itself is burned. Such actions will help save the rest of the raspberry tree from infection.
Anthracnose, rust and septoria blight respond well to treatment.
Insect pests
Raspberries, like other fruit bushes, are attacked by parasites:
- raspberry beetle;
- raspberry stem fly;
- raspberry stem gall midge;
- spider mite;
- raspberry kidney moth;
- aphids;
- color beetle.
If you do not start to fight insects in a timely manner, they will actively multiply, lay larvae. Which, in turn, eat leaves, flowers and fruits.
Experienced gardeners get rid of insects and pathogenic microorganisms, carrying out timely and preventive treatment of raspberries.
Raspberry processing rules
The event is carried out in several stages, since different pests are activated at different periods.
The first spraying is carried out just before planting.
Funds are selected in accordance with the development phase of the bush. The working solution is prepared strictly following the instructions.
The event is carried out on a dry, windless day. This is how the best effect is achieved.
Planting material processing
How actively the plant will develop depends on the correct processing of seedlings before planting.
Follow the order of actions:
- For 2 hours, the roots are soaked in a specially diluted solution.
- Then they carefully take out the plant, straighten the roots and dry it slightly.
For processing, biological preparations are used, which have shown their effectiveness in the fight against:
- aphids;
- thrips;
- ticks.
In the first year after planting, re-processing is carried out if signs of the disease were found:
- leaves wither, curl, fall off;
- brown spots appear, which grow in size over time;
- shoots become thinner;
- the plant is withering away.
This is especially important for remontant raspberries, which yield a crop already in the first year after planting.
In this case, they resort to fungicides or broad-spectrum drugs.
Processing adult raspberry bushes
In the future, they carry out preventive treatment of the raspberry tree, adhering to the scheme:
- Before bud break. Not only plants are sprayed, but also the trunk circle is carefully treated, since it is in the upper layer of the earth that insect pests and spores of fungal diseases winter. The procedure is carried out at a temperature not lower than 12 ° C. Use a 3% Bordeaux mixture.
- At the beginning of the opening of the leaves. During this period, special attention is paid to the lower parts of the plant, which are in contact with the ground.
- During the period of full disclosure of the leaves. Once a shrub has fully grown green mass, it becomes especially attractive to various pests. At this point, it is important to carry out preventive treatment.
- In the fall, at the end of the harvest. As soon as all the berries have been harvested, the shrub begins to prepare for wintering. At this point, it is important to protect the plant from insects and pathogens of various diseases. Use copper sulfate or Bordeaux liquid.
Preventive treatment of raspberries is an important procedure. It keeps the plant healthy.
