How can you process raspberry leaves in holes: we save the bush with home and store means
If the raspberry leaves are in holes that resemble punctures, this means that the plant is methodically eating some pest. Prevention measures will help to cope with it, as well as the treatment of the culture with special preparations.
Who harm raspberries
Information on the main pests is presented in the table:
| Parasite | Description |
| Raspberry kidney moth | The insect loves to live in old plantings. These small butterflies, with a wingspan of 10 mm, are a serious enemy of the raspberry. Depending on the size of the population, they destroy 20 to 90% of the crop. First, the kidney moth, the peak of which is in March-April, destroys the buds, then goes to shoots and green mass. Caterpillars penetrate the shoot and completely eat it away. Moth larvae harm the kidneys, and butterflies prefer flowers, where they lay their larvae. |
| Raspberry beetle (raspberry) | The pest crawls into raspberry flowers and lays the larvae in the berries. As a result of its activity, the shoots wither, the leaves dry out, the berries become wormy and rot. In the absence of intervention, the raspberry plant is able to destroy the entire crop. |
| Raspberry flea | The larvae of the pest cause particular harm to the plant. Caterpillars prefer to eat green mass. The flea can destroy up to 50-70% of the crop. |
| Weevil | The pest begins to get dirty in the spring when the air temperature warms up to +14 degrees. The female lays eggs in the berries. The weevil is an active pest. As a result of his activity, you can lose up to 90% of the crop. |
Fighting raspberry kidney moths
The main methods of fighting the parasite:
- regular thinning of thickets - dead remains must be cut off and destroyed in a timely manner;
- the elimination of wild raspberry thickets - it is from them that the kidney moth moves to home culture;
- spraying with Karbofos emulsion (0.2%) - this should be done when the caterpillars come out of hibernation;
- processing of shoots with a solution of "Nitrafen" (2-3%);
- spraying shrubs with "Chlorophos" solution (0.3%) - to prepare the solution, it is required to dilute 30 g of the preparation in 10 liters of water;
- timely destruction of caterpillars with an oil emulsion (1%) - to prepare a solution, it is required to dilute 100 g of the drug in 10 liters of water.
Raspberry control
Best methods against pest:
- regular thinning of plantings - it is necessary to provide raspberries with access to ultraviolet light, as well as good air circulation;
- destruction of pupae that hibernate in the remains of vegetation and in the ground - this can be done by digging up the site, the procedure is recommended to be carried out in spring and autumn;
- timely feeding of the culture with organic fertilizers and ash;
- regular weeding - there should be no weeds or other vegetation near the raspberries;
- constant inspection of bushes and removal of beetles and larvae - the procedure is carried out before flowering, the collected insects can be fed to the birds or burned.
Advice
The proximity of a raspberry curtain with a cherry, apple or pear is highly discouraged.
Raspberry flea control
It is necessary to remove this pest in a comprehensive manner. One of the best practices is adhering to agricultural practices:
- soil loosening - the procedure is carried out during pupation. This is a preventative measure that prevents the emergence of a new generation of raspberry flea;
- maintaining a suitable level of soil moisture - watering raspberries should be timely and abundant, because the flea does not like moisture;
- weed control.
Weevil control
This pest will be destroyed by the following measures:
- planting garlic next to raspberries - 1 onion is enough for 4 bushes. Also, the weevil is afraid of marigolds and marigolds;
- timely removal of fallen buds;
- the use of garlic infusion - for its preparation, it is necessary to chop 150 g of garlic, dilute in 10 liters of water, mix well and insist for 24 hours, then use it to spray the bushes every evening;
- the use of an onion solution - the husk must be combined with celandine in a ratio of 2 to 1 and poured with boiling water. Then the solution is cooled, filtered and diluted with cold water to 10 liters. Then it is filtered again and combined with 50 g of households. soap. The finished product is allowed to be used for spraying large and small leaky raspberry leaves;
- the use of "Fufanon-Nova" (2000 ml / 10 bushes) before and after flowering of raspberries, and after harvesting - "Iskra-M" (2000 ml / 10 bushes) - is recommended if the parasite population has grown strongly;
- spraying with a solution of laundry soap (during budding) - to prepare it, you need to dilute 200 g of soap in 10 liters of water;
- application of capsicum infusion - thoroughly grind ½ kg of dry pepper and combine with 10 liters of water. Insist 48 hours, filter, combine with juice from the squeezed pulp. Use to spray raspberries every 48-72 hours.
Advice
It is recommended to plant raspberries as far away from strawberries as possible. Ideally, it is recommended to completely abandon the planting of garden strawberries.
Prevention
As a preventive measure, it is required to apply fertilizers in a timely manner. This helps to strengthen the plant.
With the arrival of autumn, digging of soil, burning of old shoots and mulching are mandatory.
The use of drugs
If holes appeared on the leaves of raspberries, then they can be treated with the preparations given in table 2.

Parasites easily colonize raspberries. This plant is hardy and is unlikely to die from an invasion of pests, but the crop will be severely affected. Therefore, it is important to periodically inspect the curtain, observe agrotechnical rules and start treatment on time.
