Pears, like other fruit crops, are often attacked by insects. Among them there are leaf-sucking, leaf-eating, as well as pests that infect flowers and fruits. Processing a pear in the spring from pests is an important event that should not be neglected. About what drugs are needed to protect pear trees from pests, the rules for their use, will be discussed further.
Rules for processing pears from pests
In order for the fight against harmful insects to be successful, you need to know some of the nuances:
- Remove old bark, mosses and lichens from pear tree bark with a stiff brush. You need to work carefully so as not to damage a healthy bark.
- The first treatment is carried out at a temperature above +5 degrees early in the morning or in the evening. Choose clear, windless weather. The presence of precipitation will make the treatment useless.
- Spraying is carried out not only on the crown of the tree. They also process the trunk of a pear, the soil in the near-trunk circle, since pests can be everywhere.
- Solutions are prepared immediately before processing in accordance with the instructions. When working with chemicals, you need to use protective clothing so as not to harm your health.
- For processing in the spring or autumn of young pears, mild preparations are used so that the plants do not get burned.

During budding | “Nitrafen” | |
When the flowers open | Karbofos | |
Until the buds open | Leaflet | “Nitrafen” |
“Chlorofos”, “Fozalon” | ||

How to treat a pear in the spring from pests
Spring processing of pears and apple trees is carried out several times during the growing season (time will be different in each region):
- Early in the spring, as soon as the snow melts, to destroy overwintered pests.
- Before swelling of flower buds to control larvae.
- Then the trees are treated for ticks and other pests when the buds open and when most of the petals fall off.
- The last processing of pears or apple trees in the spring is planned after the fruits begin to set. This event is necessary to consolidate the results and increase the resistance of fruit trees to pests.
Autumn pear processing
Severe cold in winter leads to the appearance of cracks and frost cracks in the pear bark. It is in them that pests and pathogens settle. It is in the fall that special measures must be taken to protect fruit trees. Most often, copper sulfate is used to process pears in the fall.
Measures to protect pears from pests:
- You need to start processing pears when most of the foliage has flown around. Spraying from harmful insects is carried out twice: the first solution is made, as usual, the second is much stronger.
- In October, pear trunks and skeletal branches are whitened.
- In November, they are again treated with solutions from pests.
Processing trees in spring or autumn from any pests is carried out only in dry weather without wind. It is desirable that there is no precipitation for at least one day. The first frosts cannot be the reason for postponing the planned work, because during the day there are still positive temperatures. It is in such weather that strong solutions of drugs will not cause burns.
Preparations for processing pears
Since the variety of insects is large, the preparations for their destruction in spring, summer or autumn are somewhat different. For processing use:
- chemicals;
- antibiotics;
- folk remedies.
Chemicals
To save pears from harmful insects, chemicals are used in spring and autumn. You need to work with them in protective clothing, as many of them are unsafe for the human respiratory system.
Preparation | Diseases or pests | Terms of Use | Deadlines |
1% solution of Bordeaux mixture | Scab, rust, pests wintering in tree bark and soil | 5 g of the substance is diluted into 100 liters of water | During bud formation, after flowering. Then 4 more times every 14 days |
3% Bordeaux mixture solution | destroyed | 300 g for 5 L of water | In autumn before wintering |
Copper sulfate | 50 g for 5 L of water | During kidney swelling | |
Colloidal sulfur | 50 g per 5 l | Process a pear in the spring 5 times with a break of 10 days | |
Decis, Topaz, Aktara | Ants, aphids | According to instructions | As pests appear |
“Nitrafen-300”, “Karbofos-90” | Gall mite, scale insect | 300 mg “Nitrafen” diluted in 10 liters of water | Early in spring, while the buds are just beginning to swell, and immediately after flowering |
Other chemicals to save pears from harmful insects in spring and autumn:
- “Spark double effect”;
- “Nemabat”;
- “Nurell D”;
- “Aktofit”;
- “Kinmix”;
- Omayt;
- “Calypso”;
- “Horus”;
- “Bitoxibacillin”;
- Actellik.
To process pears in spring or autumn for the winter, chemicals are diluted strictly according to the instructions. Otherwise, you can harm the plantings.
Antibiotics
Various antibiotics are used to treat pear trees from a bacterial burn. According to some gardeners, they are much more effective than many chemicals.
Antibiotic | Application |
cin | 1 ampoule for 5 liters of liquid |
Streptomycin | |
Gentamicin | 1-2 tablets dissolve in 5 liters of water |
You can use one of the antibiotics for treating garden plants from harmful insects and diseases in spring and autumn for no more than 2 years, since pathogens develop strong immunity. For the same reason, experienced gardeners recommend using drugs alternately. When treating a pear with antibiotics, the dosage of the drugs is taken into account.
Folk remedies

- Smoking tobacco. Raw straw is piled up, tobacco dust is added and set on fire. In order for the smoke to be evenly distributed throughout the garden, dry weather is chosen.
- A solution is prepared from 10 liters of water, 40 g of citric acid, 25 g of ferrous sulfate. Plantings are abundantly sprayed with this mixture in spring, summer or autumn from various pests.
- Humus (10 kg), iron vitriol (6 g) are dissolved in 150 liters of water. With this solution, the soil is shed along the grooves in the near-stem circle.
- Dandelions. 500 g of green mass with flowers is poured into 1 liter of water. A day later, the infusion is boiled for a quarter of an hour, then chopped garlic cloves (2 large heads) are added, boiled for 5 minutes. The cooled broth is filtered and diluted in 10 liters of water. Rub 30 g of green soap, add to the composition. Spray the trees 1 time in 7 days until the pests disappear. Work can be carried out from spring to autumn.
- Marigold. 100 g of flowers pour 1 liter of water and boil. After 5 days, filter, dilute in the same amount of water and process the pears.

Tips from experienced gardeners
Beginning gardeners should understand that when saving a garden from harmful insects, one should not forget about one’s own safety:
- Treat trees in protective clothing. First of all, protect the respiratory organs and eyes.
- After completion of work, wash thoroughly and rinse your mouth.
- The dishes in which the solution was diluted are washed.
- The remaining funds are disposed of in places inaccessible to children and animals.
- For work use manual or automatic sprayers.
- During spraying, a person should stand at a distance of 75 cm from the pear.
Conclusion
Processing pears in the spring from pests is an important preventive measure. Despite the fact that breeders are trying to create fruit crops with high immunity to harmful insects, there are still varieties of pears and apple trees that require special treatment. If timely spraying with chemicals or folk remedies is not carried out, then you can lose the crop or the trees themselves.
