When to spray apple trees against pests: advice from experienced gardeners

I was not the only one who saw apple trees completely entangled in cobwebs . And the tracks hanging down like parachutists landing.

And we often hear: “Guard! What to do? Half the apple tree was devoured . Some things can be saved. But sometimes it’s too late.

But you need to have a harvest and not eat a bunch of pesticides . Therefore, in this article we will consider the question of when to treat apple trees for pests so that this treatment is as harmless and effective as possible .

When to spray apple trees for pests?

I have friends who want to process it once and solve everything.

Experienced gardeners believe that it is ideal if you do about 15 treatments with various preparations per year. And even after this, the damage will be within 10-15% . This means you need to select the minimum number of necessary treatments.

But residents of the southern regions and forest-steppe have to carry out pest prevention and extermination treatments more often. Or look for stronger drugs.

Pests overwinter better, reproduce more, get used to the drugs (last year it was effective, but this year, as I ironically, it’s already like feeding). One drug is not enough, but a tank mixture is needed.

Since processing must be done almost all year round, a systematic approach is needed

Before you fight a pest, you need to know it.

What does the pest like and what does he hate?
When does it appear and how does it hibernate?
When, how much and how best to present it to him, for breakfast or dinner.

There are at least 30 different types of pests that want to eat more than just apples. But also roots, bark, and leaves. Such diversity. And below we will dwell in more detail on their characteristics.

Watch the video on how, when and why to spray fruit trees in the garden:

Cortical damage

If the tree bark is damaged, the first step is to remove all diseased tissue to healthy wood using a knife or round chisel. Then prepare a mixture consisting of 3 liters of water, 150 g of copper sulfate, 5 liters of clay, 2.5 liters of slaked lime, 2.5 liters of ash. The resulting composition is stirred with a mixer and the resulting mash is applied to the sore spot. Old gardeners advise adding fresh mullein to the composition so that the tree receives nutrition through the bark.

Lichens and moss

Lichens themselves do not pose a threat to apple and pear trees, because they settle on the surface of the bark without penetrating deep into the wood. The danger is that after rains, the clean surface of the bark quickly becomes dry, and the bark under the lichens does not dry out for a long time. These places create a humid environment and favorable conditions for the development of fungal diseases. Therefore they need to be removed. Lichens are removed using:

hard mittens;
wooden spatula.

Then prepare a healing solution:

150-200 g of iron sulfate
10 liters of water;
the ingredients are mixed;
pour into a garden sprayer;
process wood.

Attention! This procedure is carried out in the spring, when the foliage has not yet blossomed.

Fighting bark beetles and aphids

If small longitudinal grooves and small holes are found on the bark, we can conclude that there is a bark beetle under the bark. To rid apple trees of such pests, you need to dilute the pesticide, draw it into a syringe and inject it into the holes. Aphids are carried to plants by ants, which feed on the sweet juice secreted by the aphids. Therefore, when fighting aphids, it is necessary to simultaneously strike at the ants. When aphids attack an apple tree while the apples are hanging on it, gentle control methods are used. Composition No. 1:

grate 200 g of laundry soap;
dissolve the shavings in 10 liters of warm water;
treat the wood with the solution for a week;
Anteater is added to the ants.

Method No. 2 involves exposing aphids to ash, from which they die. For this:

the plant is moistened abundantly with water;
Sprinkle ash on all aphid colonies.

Method No. 3 uses garlic:

200g garlic grated or finely chopped;
pour 1 liter of water;
leave for 2-3 days;
filter;
trees are processed.

Fighting the leaf roller

The leaf roller caterpillar causes great harm to fruit trees. During the summer season, 4 generations are replaced. It can be destroyed using chemicals, but then it will be impossible to eat apples. Therefore, old gardeners use wormwood infusion for spraying. Water and herbs are taken in equal quantities. The wormwood is first finely chopped and left for 25 hours. The solution is brought to a boil, filtered, diluted 2 times and the wood is treated 3 times within a week. For adhesion, add a few drops of liquid soap to the solution.

Diseases

Bacterial diseases of apple and pear trees include black cancer. Most often, infection occurs due to the use of dirty tools to remove branches. The disease is accompanied by blackening of the trunk, as if it had been scorched by fire, and drying out of the bark. If the lesions are small, then this area is cleaned with a chisel to healthy tissue and treated with 1% Bordeaux mixture or 3% iron sulfate. In case of extensive damage, gardeners advise immediately cutting down and burning the affected branches.

Scab

Scab appears in the summer, when the fruit is already hanging on the apple tree. Appears as brown oily spots on leaves and apples. Cool summers with rain contribute to the appearance of the disease, but hot summers with abundant night dew also cause scab to appear. Prevention of the disease is:

autumn cleaning of leaves under apple trees, putting them in compost;
tree trunk circle free from weeds;
unthickened crown, well ventilated after rain and illuminated by sunlight.

To combat scab in early spring, concentrated solutions of mineral fertilizers are sprayed around the tree trunks of apple and pear trees. To do this, mix:

2.5 liters of water;
165 g of urea or 250 g of urea, or 250 potassium chloride.

Then prepare another solution and spray the trunk and branches with another solution, treating the tree before the leaves bloom:

1 liter of water;
40 g lime;
30 g of copper sulfate.

Natural preparation

Colloidal sulfur is a natural preparation that contains sulfur in its pure form. It serves as both a fungicide and an insecticide, helping plants fight various types of diseases. When processed, it covers the foliage with a thin layer and, when interacting with moisture, forms sulfur compounds that have a detrimental effect on harmful insects and diseases. Shows its abilities most fully at a temperature of +20 degrees.

When planting even the most productive and disease-resistant variety of apple or pear tree, you should not hope that the tree will not require maintenance. To obtain a good harvest and keep the apple tree healthy for many years, gardeners treat the trees in the spring against pests and diseases and monitor the condition of the fruit trees in the summer. Only in this case is it possible to get a full harvest.

Drugs

A garden without chemicals is ideal. And biological agents are a good way . And “good” bacteria and viruses help, destroying harmful insects and pathogens of tree diseases.

But we often use chemical ones:

Faster and longer acting;
Easier to prepare;
More accessible.

But they are more dangerous for health:

Dosage;
Compliance with safety measures.

But don't forget about folk remedies!

Processing grapes in early spring

How you process the grapes at the beginning of the season directly determines whether they will bear fruit. Caring for grapes in the spring begins with removing debris, pruning dry vines, removing damaged shoots, and cultivating the soil.

The main enemy of grapes is fungal diseases. The first preventive treatment begins after the winter covering material is removed from it. At this time, you can use a 2% solution of copper sulfate or Bordeaux mixture. Also at this time, the vine can be treated with a solution of iron sulfate (at the rate of 200 g of the drug per 10 liters of water), such treatment will help protect not only from diseases, but also harmful insects hibernating under the bark.

During the period of bud opening, grapes are treated with drugs against grape mites.

Timing by growth phases

The timing of orchard treatment depends entirely on the growth phase of the apple tree, the presence of a pest and weather conditions.

From February to March:
From April to May:
pink bud - before flowering;
falling of flower petals.
Late May - June - ovary formation, fruit growth (1-2 treatments);
From June to July - fruit growth (2-3 treatments);
August - September - fruit ripening (1-2 treatments as necessary);
October - November - after harvesting and falling leaves;
Winter - protection from rodents.

ADVICE! The number of treatments depends on the age of the garden and each tree:

5-7 years - 7-8 treatments;
8-15 years – 8-9 treatments;
Over 15 years - 10 treatments.

Fertilizing apple trees in spring

In early spring, they begin to fertilize the trees in the garden. At this time, the plant requires a lot of nitrogen to grow green mass.

Apply 30-50 g of urea per 1 sq.m of trunk circle (depending on the size of the plant). Urea can be replaced with organic matter (a solution of bird droppings 1:20, manure 1:10 or mature compost). For one mature tree you need to add 2-4 buckets of organic matter.

Later, around May, add 30-50 g of simple superphosphate or 80 g of phosphate rock (per 1 sq.m.) into the soil around the tree trunk. And also 20-25 g (per 1 sq.m.) of potassium sulfate. Or replace these fertilizers with 30-50 g of nitroammophoska. You can also use humates.

Your first garden: what, how and when to feed fruit trees in spring
Spring fertilization of the garden is an important stage in caring for fruit trees. Find out how to carry out this operation with maximum benefit for the plants.

First spraying

Before charging the sprayer, remember:

Have you done any trimming?
Have the trunks been cleared of damaged and exfoliated bark and lichen?

And carry out the first spraying when the buds are dormant and the average temperature is about 5 degrees Celsius.

Options and more:

Preparation 30B, copper sulfate;
DNOC;
Hom and Fufanon.

During the growing season (April-May)

When the buds swell (the period of the so-called green cone ):

Aktara or Enzhio with Horus;
Copper sulfate;
Urea;
Nitrophen.

Before flowering (the so-called rose bud ):

Angio with Horus and Tiovit Jet;
Bordeaux mixture.

Attention!

Spray with complex preparations or tank mixtures (well-compatible preparations);
Do not treat apple trees during flowering.

When the leaves turn yellow

Try to determine the cause and act without delay:

Insufficient watering - water;
Lack of fertilizers (nitrogen) and microfertilizers - feed;
The appearance of pests or diseases - treat with insecticides and fungicides;
And it’s even better if you do everything together.

After flowering

Spray in May:

From caterpillars of codling moths and leaf rollers;
Aphids;
Weevils;
Sawflies;
Ticks.

To prevent diseases:

Angio and Horus;
Karbofos;
Benzophosphate;
Chlorophos.

After 2-3 weeks, carry out another treatment. Spray apple trees with ovaries 7-10 days after the flower petals fall.

Is it possible to spray when there are already fruits?

For clarity:

During the formation of the ovary (2nd and 3rd decade of May), the codling moth butterfly and lays eggs, and in late May - early June its caterpillars appear: Skor (Topaz);
Lufox (Match).

At the end of June - beginning of July, the second generation of codling moth caterpillars ;

And 2-3 more treatments.

Spraying an apple tree with fruits.
Remember! Treatment is stopped 20 days before fruit ripeness.

Treatment in autumn

Meaning:

Disease prevention;
Destroy the pest in the soil, bark, and branches.

Not only spraying, but a whole range of activities:

Collecting leaves and moths from under trees;
Digging tree trunks and soil;
Sanitary pruning;
Whitewashing trunks.

When to spray apple trees for pests in the fall :

After harvest and leaves fall;
In calm weather and without rain: Urea (urea);
Fufanon;
Inkstone.

Under what conditions are there exceptions?

You cannot treat a blooming apple tree, but sometimes this procedure is the only way to save the tree. A simple example is that a gardener did not carry out preventative spraying before the buds formed. With the beginning of flowering, pests quickly began to destroy the apple tree.

Apple codling moth
Another example is the epidemiological situation when the garden is susceptible to pest invasion. During this period, early spring treatments do not provide reliable protection, since the effect of the drugs has already ended.

Apple comma scale
The exceptions include:

Rapid destruction of apple flowers by the flower beetle. When visual determination reveals the death of more than 50% of the buds, the tree is treated with Aktara or Decis.
Heavy infestation of apple trees by mites. The flowering tree is treated with the drug "Antiklesch" or "Aktellik".
Intensive destruction of apple trees by gnawing pests. The tree is sprayed with “Entobacterin” or “Dendrobacillin”. Even if insecticides did not eliminate 100% of the pests, they helped delay the problem and give the apple tree time to bloom. After flowering is completed, heavy artillery is used in the form of aggressive insecticides “Imidacloprid” or “Chlorantraniliprole”. The drug Thiamethoxam has a powerful effect.

Apple flower beetle (weevil)

On a note! Spraying a flowering apple tree will reduce the harvest or there will be no harvest at all. However, the use of chemicals for exceptional purposes will help save the tree, which will bear fruit the next season.

Timing of spraying with different preparations

A few words about the drugs:

Insecticide – against harmful insects;
Fungicide - against all diseases;
Contact : hit the pest and he is not a tenant, and quickly;
Lasts about a week, rain washes off immediately.

System (complex):

lasts for about two weeks;

penetrate into the wood tissue;

act on larvae and eggs.

Fungicides

Iron sulfate (ferrous sulfate)

For the prevention, treatment and fight against scab, lichens, rot, moss;

Pest control (destruction of laid eggs).

Use a 3-5% solution:

In early spring before buds open;
Late autumn, as the leaves fall.

Be careful with deadlines! May burn budding buds and leaves.

Copper sulfate (copper sulfate)

Use for the prevention and control of fungal diseases (scab, black cancer, fruit rot, moniliosis);
Disinfects wounds on trees due to debris and cutting;
Disinfects the soil.

Apply in the spring before buds open, after flowering and in the fall.

Bordeaux mixture (a mixture of lime and copper sulfate)

For the prevention and treatment of fungal diseases : you can prepare either 1% or 3%;
Use immediately after preparation (flakes may form).

Carry out preventive treatments every 10-12 days;

Effective with 2-3 treatments.

A small inconvenience! Compliance with the cooking technology is required, and additional time is required.

How to spray apple trees at the “pink bud” stage

From diseases

If apple trees suffer from powdery mildew, another (third) treatment will not hurt. For example, with the drug Tiovit-Jet or colloidal sulfur (70 grams per 10 liters of water). Against scab and moniliosis, repeated spraying with the drug Rayok ( Skor ) or Strobi .

And if weather conditions permit, that is, it is already above +15°C outside, you can switch to biological products that are safer for both humans and bees.

Biological preparations for garden diseases

Fitolavin

Fitosporin

Planriz

Trichodermin

Pentafag-S

Gamair

Gaupsin

From pests

In the phase of bud formation, apple trees already need protection from leaf rollers and codling moths. In case of pest infestation, you have to rely only on the effectiveness of chemical pesticides. And for preventive purposes or when the number of insects is small, biological preparations can be used.

Chemical insecticides for spring treatment of apple trees

On the one hand, the fight against sucking pests is still relevant, on the other hand, it’s time to use drugs that destroy gnawing insects. After all, along with the first leaves, their eaters also awaken. Therefore, we will consider several insecticides against codling moths and leaf rollers with different active ingredients:

Herald. The active substance is diflubenzuron (hazard class 2 for bees). The main advantage of the drug is that it acts on caterpillars and eggs laid on treated trees - that is, on those who gnaw our apple trees. Consumption rate of the drug: 10 milliliters per 10 liters of water.
Stozhar. The active ingredient is acetamiprid (hazard class 2 for bees). A fast-acting systemic contact drug against the codling moth. The first results are visible within an hour after spraying, and the protective effect lasts up to 21 days. It is characterized by low toxicity to pollinators. To prepare the solution, 40 grams of the product are dissolved in 10 liters of water.
Fury ( Taran) . The active ingredient is zeta-cypermethrin (hazard class 1 for bees). On apple trees it destroys codling moths, leaf rollers and aphids. It affects both adults and larvae. It is diluted at the rate of 1.5 milliliters per 10 liters of water.
Inta-vir . The active ingredient is cypermethrin (hazard class 2 for bees). Used to protect apple trees from codling moths and leaf rollers. For 10 liters of water, 1 tablet of the drug is needed.
Sumi-alpha ( Senpai ). The active ingredient is esfenvalerate (hazard class 1 for bees). It acts quickly, the caterpillars begin to die 0.5-2 hours after treatment. To combat codling moth and leaf roller, 5 milliliters are dissolved in 10 liters of water.

Modern insecticides do not accumulate in plants and (if used according to instructions) do not pose a danger to people and pets. Nevertheless, bees, predatory insects, and fish suffer. Therefore, if it is possible to do without pesticides, it is better to use it. For example, arm yourself with biological products.

Biological products for pests

Fitoverm (analogs - Aktofit , Kleschevit , Akarin ). The active ingredient is aversectin S. Insectoacaricide against codling moths, cutworms, leaf rollers, moths, and ticks. The consumption rate is 20 milliliters per 10 liters of water.
Bitoxibacillin (based on Bacillus thuringiensis var. thuringiensis). Insectoacaricide against codling moths, leaf rollers, moths, moths, ticks. The consumption rate is 70 milliliters per 10 liters of water.
Lepidocide (based on Bacillus thuringiensis var. kurstaki). Insecticide against codling moth, leaf roller, hawthorn, moth, moth. The consumption rate is 20-30 grams per 10 liters of water.
Biokill . The active ingredient is abamectin. Insectoaccaricide against mites, aphids, codling moths, leaf rollers, cutworms and apple honeysuckers. The consumption rate is 4 milliliters per 10 liters of water.

Remember that biological drugs are active only in warm weather, above +15°C-18°C. At lower temperatures, it is useless to treat anything with them.

Treatment by pest type

To avoid wormy apples, it is necessary to carry out a set of measures to combat the codling moth from the appearance of butterflies until the fall (see below).

From scab in the spring

After spring pruning (but before the leaves appear) - 5% urea;
Before the appearance of fruits - preparations containing copper (copper oxychloride, etc.);
After harvesting - 1% Bordeaux mixture;
If infection occurs, use a complex of minerals (ammonium nitrate, ammonium sulfate, potassium salt).

Scab on an apple tree.

From the codling moth and to avoid wormy apples

Caterpillars appear 12-15 days after early apples fade;
In winter they are found under the bark, in hollows, and in the soil.

Measures:

Peel the trunks from dry bark onto film and burn;
Dig up the soil around the trunks;
Install and clean fishing belts;
Spray: after shedding the petals of winter apple trees;
repeat in two weeks.

They use karbofos, chlorophos, trichogramma.

Apple flower beetle (fruit weevil)

In winter it is found in fallen leaves, under the bark .

Spray:

When buds open;
When the ovary falls off against young beetles.

Chlorophos is very effective.

From fruit rot (or moniliosis)

The disease is infectious and is promoted by:

Unpicked diseased apples, both fallen and on the tree (including last year’s);
Damage by various pests.

That's why:

Collect and destroy affected fruits;
Treat the tree: against pests with insecticides (primarily moths);
for diseases - Bordeaux mixture, copper sulfate.

From the leaf roller

In winter, it hides in the bark, on the branches near the buds ;
Appears when the buds swell and open;
Curls the leaves.

Process:

Nitrafen in early spring;
Infusions of tobacco;
Karbofos;
Chlorophos.

Install:

Hunting belts;
Jars of fermenting molasses for catching butterflies.

Leaf roller.

From insects (and there are many of them)

Bark pests - bark beetles, scale insects, mites.
Pests of foliage, ovary, flowers, buds - caterpillars and beetles of leaf roller, hawthorn, and copperhead.
Fruit pests include leaf roller and codling moth caterpillars, sawflies.
Sucking pests - aphids.

To have fewer of them:

Collect and destroy fallen leaves and fruits;
Dig up the tree trunk soil;
Whiten the trunks with lime;
Install catch belts;
Spray trees with insecticides.

The entire garden, and not just the apple tree, can be helped by planting plants that, if they do not destroy, then repel harmful insects: garlic, calendula, tobacco, celery, sage, mint, chamomile, rosemary, dill, elderberry.

From parasites

I would use this word to describe everyone who harms the apple tree. We have listed the most dangerous ones (including when and how to defeat them). Make sure that the harm from them is minimal.

From ants

At one time I was an ardent supporter of their usefulness for the garden, but time moves on. Now for me a colony of ants is aphid carriers:

You can make ditches with water if you have a lot of old tires;
Build catcher belts and clean them periodically.

Also use Antiant and others.

From caterpillars

This could be a leaf roller, a codling moth (which we have already discussed above), a hawthorn, an apple sawfly, a silkworm and others:

Therefore, the fight against them must be carried out not only when they are already crawling, but even at earlier stages and in complex;
Agricultural technology and spraying.

From lichen

Appears on old apple trees . Prevention is done early in the veins and in the fall:

in a timely manner ;
Clean the trunks with a stiff nylon or metal brush: from growths;
from peeling bark.

Lubricate cleared places:

clay mixed with lime;

a thick solution of lime and copper sulfate;

strong 10% concentration of iron sulfate.

It is believed that lichen even protects the tree.

From whitefly

This quarantine pest species can be a carrier of viral and fungal diseases .

Process:

Biological: Bitoxibacillin, actofite – 2-4 treatments at the growing season;
Chemical: treatment with one drug is not enough. You already know insecticides (Fufanon, Preparation 30B, Aktara, Confidor maxi, Iskra m, Karbofos and others);
Folk remedies: infusions of onion peel, garlic, yarrow (treatment every 2-3 days).

Whitefly.

How to properly and effectively process an apple tree

Annual spraying will help treat or prevent pathogens and insect infestations. That is, such a procedure, if performed correctly, can only provide benefits for the trees and the future harvest. However, if you violate the rules and scheme of the event, you may, at best, not get the desired effect, and at worst, you may harm the apple trees or even a person (if safety precautions are violated). If you want your spring treatments to be as effective and harmless as possible, then you should know some rules and recommendations:

Observe safety precautions when preparing solutions and carrying out direct spraying.

Important! Prepare the solution and perform the procedure only in special protective clothing (PPE), that is, wear a respirator, goggles, gloves, and a special raincoat. PPE will protect your body from contact with chemicals.

After all the manipulations performed, you must immediately change clothes, thoroughly wash your skin (especially your hands and face) with clean water and soap, and rinse your mouth.
The instructions are your best advisor on the correct use of a particular substance; always study it carefully and thoroughly before use.
Spraying should be done early in the morning or in the evening.

If the weather is cloudy, but there is no precipitation (and is not planned in the near future), then you can do it during the day. But with a clear sky and bright sun, the applied solutions will begin to evaporate too quickly and will not have time to be absorbed, which means they will simply be little or not at all effective.

It is important to carry out gardening activities only in calm weather. The fact is that when a substance is finely sprayed, wind currents can carry the substance past the immediate object of irrigation, transfer the substance to a person (even if he uses PPE, this is still extremely undesirable), or transfer drops of liquid to other plants on the estate.
The first early spring eradication treatment is carried out after pruning in order to protect the cut areas on the wood, because in fact they are “open wounds” through which pathogenic microorganisms can pass. In this case, it is ideal to use a fungicide that contains copper.
strictly forbidden to use insecticides during the flowering period. If they are used during this phase, they can seriously harm pollinating insects.

In theory, you can apply fungicides during flowering, but why?

For each subsequent treatment, it is better to use new products (not just drugs with different names, but with different active ingredients) so that there is no addiction, or alternate.

To save money, of course, you can use the same products during one summer season, but next year it’s better to change them. Especially if the treatments do not give the desired result.

To avoid clogging your sprayer, be sure to filter the solution, for example, pour the liquid through a filter mesh, or through additional gauze or nylon stockings.
To prepare most solutions, water at room temperature (but vitriol dissolves better in hot water).

It is believed that to dissolve biological drugs, it is better to take clean, non-chlorinated water. To do this, it must either sit for several days or be poured through a filter.

If after using a contact preparation (for example, copper sulfate) it begins to rain , which washes away the substance, it is necessary to repeat the procedure. The fact is that rainfall washed away all the healing solution.

The situation is completely different if you used a systemic drug (Chorus or Skor), which penetrates deep into the plant in the first few hours after the procedure.

Indications for wood processing

Preventive spraying of fruit trees is carried out in accordance with the horticultural calendar. If insect pests or diseases have settled on the trees, measures to combat them should be taken immediately.

In summer, apple trees are susceptible to diseases such as:

scab;
powdery mildew;
fruit rot;
brown leaf spot.

Codling moth caterpillars, aphids, mites, codling moths, hawthorn and fruit sawflies can reduce yields and damage fruits.

The dosage of drugs and the frequency of spraying depend on the specific region. In the southern regions, where there is increased insect activity, plants need to be treated more often using highly concentrated solutions.
