You may not have paid much attention to small gnats or inconspicuous beetles on raspberry bushes. But in vain! Seemingly harmless insects can actually be very dangerous, and the sooner you get rid of them, the more chances there will be for a good harvest.
Whichever variety grows on your site, raspberries, diseases and pests can spoil a good part of the crop or even destroy the plant itself. Agree, there is little pleasant when every now and then come across beetles and wormy berries, and the shoots wither, not having time to bring the harvest. To save raspberry bushes, you need to take preventive measures and destroy the emerging insects in time.

On the Internet, you can easily find what all the listed raspberry pests look like in pictures. "Enemies" should be known by sight! By learning to identify insects dangerous to the raspberry by their appearance, you will know how to deal with them in the most effective way.
If insects appear in your raspberry plant that cause irreparable harm to the stalks of raspberries, you will have to mercilessly cut out all the spoiled shoots and immediately burn them. Pruning is usually done in the fall, when the entire crop has already been harvested, or in early spring. When raspberries are affected by stem gall midge, the shoots are cut slightly below the characteristic swellings; in all other cases, it is advisable to cut off the infected stems at the root.
To deal with a common raspberry beetle in the morning, the raspberry bushes are shaken: the beetles fall on a film lying on the ground, from where they are collected and destroyed.
When the buds are formed, the raspberry tree is abundantly sprayed with infusion of tansy in the evenings (for five liters of water, a kilogram of fresh tansy and 350 grams of dried - insist for a day, then boil for half an hour, strain and add cold water to make 10 liters of infusion). In the autumn months, under the raspberry bushes, the soil is dug to the depth of a shovel bayonet, thereby destroying the larvae and beetles that have settled down for the winter.

Digging also helps to partially destroy the raspberry fly larvae. To completely get rid of this pest, before the appearance of flowers, raspberries are treated with karbofos or emulsions of drugs "Confidor», «Spark", And the wilting tops of the shoots are cut off and burned every two weeks.
From the spider mite and from the strawberry-raspberry weevil, raspberry bushes are sprayed with fufanon before flowering and after picking berries, or “Spark"And"Confidor". The same measures are taken when raspberries are severely affected by a kidney fly (in addition to pruning damaged stems).
Of course, it is better to protect raspberries in advance from a possible invasion of "uninvited guests" than to fight with all your might to preserve the harvest.

To combat rodents in the backyard, you can use not only mousetraps and cats. Get a hedgehog or if you find a hole, pour boiling water there. Plant "imperial hazel grouse" or black root bulbs on the plot, they are guaranteed to ward off all small pests.
You can fight caterpillars with the help of birds. Hang a couple of birdhouses in the area and sometimes throw food to the birds. Birds will eat not only food, but also nasty insects.
A three-day infusion of burdock can help with cabbage caterpillars. They spray the plant once every 6-8 days. Spraying course 1-2 months.
You can get rid of slugs thanks to traps. You need to throw a damp cloth in a shady place, and these pests will collect there. Next, you just need to sprinkle them with salt.
If you are tired of the Colorado potato beetle, but you are not a supporter of chemicals, use infusions of various herbs. For such infusions, hot pepper, bitter wormwood, large burdock leaf and high honeysuckle are used. You can plant calendula on the site. Another enemy of the Colorado potato beetle is the smell of beans.
Bears do not tolerate pungent odors. Plants such as calendula, garlic, and parsley will help repel them.
If you find a bear's mink, fill it with a solution of kerosene and washing powder. Proportions 1: 2 for 7 liters of water. Immediately after this, the bear will crawl out and it can be destroyed.
Aphids and spider mites are the nastiest pests of Rosebushes. To combat them, the use of soap solutions is well suited. But you need to manipulate each bush daily. So this is painstaking work on a personal plot.
It is very important when growing raspberries to protect them from diseases and pests that can significantly reduce yields. It is necessary to follow agrotechnical rules and take preventive measures. The most common raspberry diseases are: gray rot, anthracnose, purple spot, mosaic, rust, chlorosis, raspberry overgrowth. The main pests: aphids, raspberry flies, spider mites, stem gall midge. In order to take the necessary measures to heal the plant and save the harvest, you need to learn to recognize the enemy or disease and know their signs.
There are several varieties of raspberries:
All of them are quite often subject to disease, which is associated with improper care of the plant. Even a slight deviation from the rules of cultivation leads to various problems. You need to be attentive to this shrub in order to identify the disease at an early stage of development. It will be much easier to deal with it this way.
Gray mold is the most common disease. Small gray spots appear on the fruits, which gradually increase and affect the entire berry. It begins to rot, becomes covered with a gray bloom containing spores of the fungus. Moisture and water promote the proliferation of spores, and the entire raspberry tree is affected. The peak of the disease occurs on cool days with high humidity. Not only berries are affected by gray rot, but also leaves along with shoots. Diseased plants usually cannot stand the winter and die.
Gray rot in raspberries spreads very quickly, so action must be taken as soon as it is detected.
To save the affected plant, which may still bear fruit, it is necessary to collect all the berries affected by gray rot and burn them. Then the beds are thinned out, cutting out weak offshoots and fruit-bearing shoots to the soil level with a pruner, after which they are taken out and burned.
Several chemical treatments are carried out against fungi that cause gray rot. It is recommended to use the preparations before the berries appear. In early spring, raspberries are treated with a 3% solution of Bordeaux liquid, which allows them to destroy overwintered spores.
Before budding, raspberries and the soil around it and between the rows are sprayed with 2% nitrafen solution. During budding and after harvesting, it is recommended to spray the plant with Bordeaux liquid, colloidal sulfur suspension, as well as Albit, Tiovit Jet, Tsineb preparations, which are fungicides and growth regulators.
In the event of a massive defeat, it is necessary to destroy all the old plantings and establish a raspberry plantation in a new place. For planting, choose material that is not infected with viral and other diseases.
Getting a large harvest of raspberries is impossible without taking measures to protect the plantings. Raspberry pests and the fight against them begins from the first spring days and ends before the autumn snowfalls. To defeat the army of pests, you need to know well their appearance and lifestyle.
Wormy berries and dried shoots do not delight gardeners. The hard work of chasing a bountiful harvest can be nullified by a small gnat or midge. To prevent this from happening, you need to know how insects can damage raspberry plantations. Raspberry pests and methods of dealing with them are diverse, they must be recognized and correctly applied.
A small brownish insect with transparent wings and a length of 2 mm. Produces three generations in one season.
When the raspberry blossoms, the gall midge leaves eggs on the bottom and in the middle of the young stems. Caterpillars of orange color develop inside the stems, forming swellings on the stems - galls. Affected branches develop poorly and die over time.
In May, adult insects appear from the galls, which begin to lay eggs. Within a month, a swelling forms on the stem, above which the branch dries up.
A gray little fly 5 mm long appears in May, it does not harm the plantings itself. Damage is caused by the larvae, which she lays near the leaves and on the tops of the branches. Caterpillars are able to destroy all growth of raspberry stems, making ornate passages inside them, which makes them dry out.
The main sign of the presence of a raspberry fly is that the young tops of the branches dry or rot. In the stems, holes are visible, which are made by the caterpillars.
When the raspberries bloom, the larvae descend into the soil and hibernate there. In the spring, butterflies get out of the ground, lay their eggs at the top of the branches.
Lays eggs in stems, larvae grow in them and swellings - galls - form on the stems. Damaged stems break easily and dry out over time. The size of the swelling on the stem reaches 10 cm. The swelling in the presence of a stem gall midge is 3 cm.
Insect green or black, covered with a shiny coating. It settles in colonies at the ends of young stems and leaves in mid-spring. They feed on plant sap, slowing down its growth. Leaves and branches curl, twist, and often dry out. Often carries viral infections.
Eggs overwinter on annual stems near the buds. The awakening of the pest begins simultaneously with the blooming of the bud. Aphids reproduce especially strongly during dry periods.
A dark gray beetle with a 3 mm long proboscis hibernates in the ground under fallen leaves. Lays eggs in buds, gnawing the pedicels. A sign of the appearance of a weevil is wilted buds that hang on pedicels.
The larva in the form of a white caterpillar with a dark yellow head eats the flower inside. By the middle of summer, the larvae turn into adult beetles that gnaw on raspberry leaves.
The insect is gray or rusty in color with reddish edges, 4 mm long, hibernates in the ground, appears on raspberries in May.
Eats weed flowers, then moves to the raspberry buds. Eats buds from the inside, ovaries and leaves. Lays eggs on leaves and flowers. The yellowish caterpillar with transverse stripes eats the berries, resulting in worminess and reduced yields. In July-August, the caterpillars climb into the ground, and in the fall they turn into an adult insect.
An insect with a striped, black and yellow color, transparent wings, resembles a wasp. The wingspan is about 3 cm. It hibernates inside the stem or in the roots of raspberries, in the swellings - galls.
June begins her years. Lays eggs in the soil at the base of the stems. The larvae bite into the shoots and roots inside, causing them to dry out. Overwintering and pupation takes place inside the stem or root. In June, new butterflies come to the surface and begin a new breeding cycle.
In early spring, moth caterpillars appear, which hibernate in damaged stems or under fallen leaves. The larva eats buds, takes root in the stem and pupates in it in May. At the beginning of raspberry flowering, moth butterflies appear.
An adult butterfly of dark brown color with light and golden spots lays eggs in flowers. Larvae appear in red with a dark brown head, which eat away the buds, stems and berries. In spring, raspberries dry out the stems in which moth caterpillars wintered.
The insect is so small that it is very difficult to see it. A cobweb is noticeable, which is located on the raspberry, on the leaves, on the underside. The tick feeds on juice, which is why the leaves become discolored, dry and fly around. Often appear after the onset of intense heat without rain.
Raspberries are affected by a tick in the spring. It appears during the opening of the leaves, settling on the leaves from below. The leaves change color, become pale and curly, and finally dry out. The insect hibernates in the buds.
Nature itself suggested how to deal with pests with them. Many insects hibernate under last year's foliage or in the soil. Therefore, the cleaning of old foliage and digging up the earth became mandatory procedures. Digging can, however, severely damage the surface roots of the garden raspberry.
The solution may be a high layer of mulch, through which it is difficult for pests to reach the soil. If the soil is mulched, a layer of mulch should be added to prevent insects from reaching the surface.
Some insects hibernate in the affected shoots, which in the fall must be examined and removed swollen, dried and damaged bark.
Chemical treatment destroys many pests. But many beneficial insects die with them, and chemicals can accumulate in berries. Therefore, this method is used in extreme cases, if more harmless treatments do not work.
In the spring, spraying of raspberries begins from pests. Processing is carried out at the beginning of the growing season and 5-6 days before flowering. During the regrowth of the branches, before flowering, they are sprayed with insecticides:
A 6% urea solution, which is watered before budding begins, helps to get rid of ticks.
In May, by the beginning of summer of a raspberry fly, the stems are sprayed with some preparation
Apply mechanical shaking off of beetles on plastic wrap and destruction.
The wilting tops are regularly trimmed and burned. If, when cutting, the hole that the insect made is visible inside, then they cut it even lower, to healthy tissue.
At the beginning of the growing season, the raspberry is sprayed with infusion of tansy. A kilogram of fresh or 350 grams of dried grass is taken on a five-liter bucket. The mixture costs a day, then it is boiled over a fire for half an hour, filtered through cheesecloth, poured into 10 liters and water is added to its full volume. This broth is poured over the branches of the raspberry tree.
Instead of infusion, tansy is used:
Infusion of garlic scares away aphids and flower beetles: 500 g of garlic is chopped through a meat grinder and poured with three liters of water. Insist for five days, filter. Diluted in ten liters 60 grams of infusion, adding a little liquid soap.
When raspberries are in bloom, any treatments on the plantation are excluded due to the potential to harm pollinating insects.
Spraying bushes with insecticides:
Akreks is carried out after harvesting. It is done up to 4 times a season with an interval of 10 days.
It is impossible to treat stems affected by pests from the inside. They need to be cut and burned.
Ammonia solution, infusion of tomato leaves, potatoes, wormwood, tansy repels aphids. An ammonia solution is sprayed on all sides of the leaves.
Prevents the spread of spider mites by sprinkling the plantation in cloudy and evening weather.
Cut off two-year-old sprouts and stems with cracks and scuffing bark, weak, diseased, unripe and excess branches.
If galls are located on the stems, then they cannot be treated. They are trimmed below the bulge. Dried, blackened stems are cut at the root.
They dig up the aisles, remove the fallen leaves.
Ways of how to deal with pests involve the systematic care of the plantation and its treatment with the strongest chemicals. Such a fight against insects can affect berry consumers in a bad way. Therefore, work must begin with preventive measures.
Prevention of the appearance and reproduction of numerous pests will be full care of the plantation. Measures aimed at increasing yields prevent the appearance of many pests. Their implementation is simple, but quite effective:
Using the recipe for a miraculous mixture invented by the outstanding gardener A.P. Bessarab, you can feed the plants, get rid of many pests. In the spring it is necessary to water the plantings, in the summer - to spray it over the foliage. Application - once a week.
Dissolve the mixture in 10 liters of water and store in a dark place for a week until everything is fermented. The principle of operation of the mixture is not in chemical elements, but in the life of microbes, which helped plants to absorb nutrients and fought pests.
The symbiosis of microorganisms with raspberries is practiced in his nursery by another outstanding gardener A. Kuznetsov. His biotechnology of natural farming involves the use of organic mulch with the germination of myceliums in it.
As a result, soil nutrition allows the cultivation of healthy raspberry plantings with an excellent berry harvest. Moreover, instead of 4-5 shoots per square. m. it grows 30-40 shoots.
Raspberry pest control begins with caring for the raspberry, cultivating the land, regulating the number of shoots, mulching the soil. All these necessary measures not only strengthen the plants, but also prevent the appearance of numerous pests.
Mostly weakened plants, neglected and overgrown, are ill. Well-groomed plantations with strong plants are almost free from diseases and pests. It is worth remembering this.
A good harvest of raspberries can be obtained only if the gardener is able to prevent the appearance of diseases and pests on his favorite shrub in time. However, if it was not possible to avoid sabotage, it is necessary to take effective measures to eliminate the problem. About the most common pests and diseases of raspberries, as well as methods of control - further.
Today, among the pests of raspberries, several dozen names of insects can be distinguished (aphids, leafhoppers, glassworms, raspberry flies, etc.). However, even experienced gardeners and gardeners do not know how to deal with them correctly and effectively. Often using chemicals, the berries absorb them and become unsafe to eat.
In order to learn how to cope with insects, you need to know their nature and weaknesses. Indeed, their appearance is often provoked by an abundance of weeds or poor-quality plant care.
As a result of poor-quality care, and the presence of various weeds around the perimeter of the territory and next to the raspberry bush, a raspberry beetle may appear. Popularly known as "raspberry", it has a small size and brown hair.
It is not easy to get rid of it, but it is possible if the spread of the larvae is prevented in time. For the first time, they appear in the soil at a depth of no more than 10 cm, where weeds germinate. As soon as the beetle larva gains strength, feeding on pollen, it migrates to a more tasty object - a raspberry bush.
The beetle first consumes the berries that grow closest to the ground. Therefore, if the gardener noticed small holes in the berries or the presence of small bugs on the leaves, this is a reason to start sounding the alarm. The easiest way to get rid of the beetle is before it regains its strength. The pest can spoil more than 15% of the crop.
However, this is not the only reason why the raspberry beetle is dangerous. Due to damage to leaves and fruits, the plant exerts strength to restore them, which can lead to a decrease in the volume of berries in the future. Moreover, the beetle is able to preserve the larvae, so the attack can be transmitted to the next season.
It is not difficult to recognize the raspberry kidney moth - it is a small insect, with the main difference in the form of a yellow head. The color alternates between yellow and black stripes. The size of an adult caterpillar is from 9 to 12 mm, it has a red tint.
The insect is able to survive the winter, so if you do not get rid of it immediately, the crop will be spoiled by the pest in the next season. The caterpillar appears already at the beginning of March, with the arrival of the first warmth, and the butterfly - with the appearance of the first flowers.
A small black beetle with a long nose infects raspberries even at the flowering stage. The elongated nose allows the beetle to extract precious nectar. After its activity, the berries may not appear. The main activity of the larvae occurs for a short period from May to June.
Early varieties are at risk:
It is better to get rid of the pest even at the stage of flowering of the plant, since the larvae are weakened and not fully formed. A sign of the appearance of a beetle is small punctures and black dots on the leaves and buds.
Ticks affect shrubs in all regions, wherever the berry grows. The leaf-bud mite most of all likes a temperate climate, greenhouses and small greenhouses are at risk. The tick loves dampness and moisture, therefore, protected plantations must be properly ventilated.
The insect is difficult to identify, often its activity is disguised as a leaf mosaic. The first sign of a tick is visible by May. Small bright specks appear on the leaves. Activity Result:
The main danger of the tick is that it is able to move around the garden with the wind. Having liquidated in one place, it will arise in another. In this case, a comprehensive pest extermination measure is required.
Often appears in the place where the young berry bush is located. Outwardly, it looks more like a simple midge, the length of the body does not exceed 7 mm. First, it affects the stem of a young plant, which leads to the death of the entire shrub. After the destruction of a young plant, it lays 5 mm larvae in areas of a strong plant.
The insect is able to endure a colossal drop in temperature in hibernation mode, so you need to fight the pest immediately. To achieve the best effect, chemical pollination and drugs are used before flowering.
It is difficult to notice the appearance of this pest due to its small size of 1-2 mm. Therefore, the problem can be recognized only by the external painful signs of the plant. The main feature of the pest is that it lays eggs in places where there is little damage. Often the stem gets into the risk zone, which leads to the death of the whole bush.
The time of appearance is the end of August, you can track it by the premature fall of leaves. The only way to fight is to cut off the affected areas, since the insect is able to survive the cold.
Popularly known as "garden gourmet", the main difference is blue wings. It is very similar to the raspberry moth, characterized by an elongated body shape. Females have only three alternating stripes of yellow and black. It is they who are the main and dangerous pest, as they lay more than 100 larvae in the stem and soil. The reason for the appearance is damaged raspberry branches.
The insect usually appears in July.
One of the most common raspberry pests is the white leafhopper. The insect is capable of destroying crops and bushes in one season. It is not difficult to detect the presence, a white bloom appears on the leaves and fruits. The main difference is that if it appeared on one crop, after a short period the entire garden and vegetable garden will be infected.
Scientists annually sound the alarm about the increase in the population of leafhoppers. Therefore, it is necessary to prepare in advance the means to combat it. Often affects crops such as:
Raspberry diseases are no less dangerous than pests. Often it is the painful condition of the bush that causes insects to appear. In order to avoid the complete destruction of the crop, you need to know about the most common raspberry diseases.
The disease is difficult to identify due to the multifaceted symptoms. The main reason for the appearance is damage to the root system. This can be caused by both the larvae of dangerous pests and the careless care of the gardener himself.
The first sign of the disease is that the leaves curl and lose color. It can be easily confused with a plant overflow. Verticillary wilting is triggered by a fungus. Treatment should be immediate, as the fungus is transmitted to healthy shrubs.
The disease is popular in areas where it often rains or accumulates dampness. A plant can also get sick in a protected greenhouse or greenhouse. It spreads quickly, but the disease is easy to identify. The first sign is that dark spots appear on the leaves, after which on the stems.
The peak of activity is in July. The disease first affects older leaves, and then spreads to young ones. If you do not begin to treat, then in a few months the disease will affect other cultures.
A dangerous fungus that spreads quickly due to wind and insects. If the disease has been noticed in other crops, all plants will have to be treated and prevented. The first sign of the disease can be detected visually, the appearance of small holes on the leaves indicates the presence of a fungus.
When working with chemicals for the treatment of plants, the gardener must wear a respirator, since if the funds get into the lungs, there is a possibility of developing an allergic reaction. At risk are plants such as:
Not only raspberry bushes, but also roses are at risk. Therefore, if an affected culture grows on the territory, then the disease will be transmitted along the chain. In this case, the gardener must take a number of preventive measures in order to stop the disease.
Ulcerative spotting is expressed in the appearance of gray spots on the stem of young plants. Over time, they become harder, which leads to infection of the entire stem and death of the plant. The only correct solution at the first stage of the development of the disease is to remove the affected parts and burn them.
Gloves must be worn when handling the affected plant.
Raspberry rust is one of the most common diseases that covers all territories. The disease cannot be ignored, since the affected bush will no longer be able to produce a crop. The gardener will have to dig it up and burn it. Moreover, the disease is transmitted to other cultures.
It is not difficult to identify the disease, the first signs are noticeable on young leaves. They acquire an uncharacteristic yellow tint. The yield and size of the berries are reduced due to the fact that the plant tries to restore the leaves.
Root rot is not a pleasant disease that is difficult to detect, as the symptoms are similar to a number of other diseases. Reason for appearance:
The main disadvantage of the disease is that it destroys the plant in a short time if it is not treated. It can only be detected through a visual inspection of the soil. If the bush is in a hole or low ground where rain moisture collects, you should limit watering and allow the earth to dry out.
The first symptoms that indicate the presence of the disease are sticky and damp stems.Root rot is a fungal disease that is transmitted to other crops.
A fungal disease that is transmitted through spores from a diseased plant is gray rot. If there is at least one diseased plant on the site, then it must be immediately treated. The disease is transmitted quickly, often occurs on the flowers of chrysanthemums and roses. Therefore, if a raspberry tree grows nearby, it should be secured in advance.
The main difference from other diseases is the presence of small gray spots on young leaves. Often occurs during seasonal rains. It is possible to get rid of mold only if agrotechnical measures are followed.
An infectious disease that affects various varieties of raspberries every year. It is easy to identify the disease, it is enough to pay attention to the root part of the plant. The growth appears closer to the stem, in the early stages it has a small shape with a sawn egg.
It is necessary to treat the plant immediately, since cancer is easily transmitted through the tools and unwashed hands of the gardener. If not treated, then by the end of the season the bush will completely die.
Curly raspberry is a dangerous viral disease, which is expressed in wrinkling and curling of leaves, over time, their edges turn yellow, become dry and brittle.
If the plant is not treated, by July the gardener should dig up a whole raspberry bush and burn it. The disease is easily transmitted to neighboring families, so if you value your harvest, it is better to treat it in the early stages.
Often the disease appears on plants that are not properly cared for. This may be due to an unsuccessful place for the raspberry plant, or a lack of watering and fertilizing the soil.
Popularly, the raspberry sprout is known as the "witch's broom". It is not difficult to identify the disease; more than 200 shoots appear on one young raspberry bush. The root system is not able to withstand such a load and provide young shoots with all the necessary substances.
Even if the bush survives a lack of nutrition, the yield will be low and frail. However, bushes affected by this disease can live up to 10 years. Therefore, several important nuances can be distinguished:
Effective and timely treatment of your favorite plant will not only save the harvest, but also save other crops from extinction. To do this, the gardener needs to choose the right remedy to combat the misfortunes of nature and insects.
Which one to choose: a folk or professional remedy - the owner of the site must decide himself. However, before that, you should familiarize yourself with all the nuances.
Chemical preparations are effective, but it is not recommended to use them for processing while the first fruits have appeared. Often, poisoning with your favorite berries and fruits is the result of untimely processing.
The desire to save the plant and the crop from death leads to the misuse of chemicals. Experts recommend using chemical agents as a preventive measure even before flowering. It is advisable to process the stems and soil without touching the foliage.
After harvesting, experienced gardeners recommend using stronger means in order to get rid of known pests. As an example, there is a small list of effective remedies:
The drugs help get rid of the fungus, larvae and the occurrence of diseases of the root system. Raspberries need to be processed in early spring and late autumn.
The use of folk remedies is effective if you need to help the plant immediately, and the use of chemistry is prohibited. Even a small sprinkle of baking soda can get rid of the huge list of insects. And the treatment with tincture of tobacco, will scare away flies from the raspberry and the invasion of cicadas.
The use of wood ash will save from the formation of fungus and mold. Even a little manganese treatment will help get rid of the infection and spread of a number of known diseases.
Folk remedies have a gentle effect on the fruit. Therefore, their use will not affect the health of the gardener. Many people choose folk remedies also because of their availability and low cost. For example, wood ash can be found in almost any country house.
Compliance with agrotechnical rules will help prevent the appearance of diseases and insects:
This is just a small part of the preventive measures that will help get rid of 70% of all problems.
In order to achieve a rich harvest, the gardener needs to take care of his raspberry and the plants that grow on his territory. When there is one hint of illness or the presence of a harmful insect, first aid is necessary. In the future, this will help save a whole vegetable garden or garden.
Raspberries, like any plant, need proper and timely care. After the seedlings have overwintered, correct pruning must be done. Pruning allows you not to thicken the planting, remove excess overgrown root shoots, cut out dried bushes and remove dry foliage. Those shoots that fruited in the previous year and the old ones are removed near the very base, those shoots that will bear fruit are shortened by 20-25 cm in early spring.
Preventive spraying of raspberries in the spring with insecticides or more ecological folk remedies is carried out. Thanks to this, pests that have hibernated inside plants or in the soil, but come to the surface in early spring, are destroyed. This creates an obstacle to their further reproduction. After the end of the season, processing of raspberries in the fall for the winter will be required to prevent insects or their larvae from hiding for the winter.
So that the treatment of raspberries in the spring from pests is not in vain, they must be carried out at the most favorable time. A delay in spraying will lead to a strong decrease in the effectiveness of treatments, many pests will not die, but will continue to reproduce.
Pest control in spring, as well as in autumn, also includes proper pruning, during which all shoots with the slightest signs of harmful insect activity are necessarily removed. Without exception, all residues after pruning, as well as dry weeds, must be burned. You cannot leave them near the plants for the winter; it is also not recommended to put them in compost.
For those pests that take refuge in the soil, autumn digging of soil is used, the depth of which should be at least 25 cm. Lumps of earth are not broken. Insects, once on the surface, will die in winter, which will reduce their number after emerging from the ground in early spring.
Many insects can harm raspberries. They damage various parts of fruiting bushes, weaken them, as a result, the plants do not develop normally, which always affects their fruiting and productivity. You can fight pests by using insecticides and acaricides, this is quick and reliable, or using any folk methods if you want to get products that are clean by environmental standards.
