Spring is the season for processing apricots from diseases and pests


Growing juicy apricots in your own garden is the dream of many gardeners. This can be prevented by tree diseases and insect pests. It is necessary to start protecting your harvest from early spring.

Spring processing of apricot from diseases

In the spring, fruit trees come out of the state of winter dormancy, and together with the trees, overwintered myceliums - spores of fungal diseases of fruit crops - awaken. Apricot is susceptible to cytosporosis, bacterial root cancer, milky shine and a number of other ailments. The spores of these fungi tend to live in the soil, feeding on decayed plant debris. Through damaged roots or the bark of the lower part of the stem, they can enter the conductive system of the wood and spread throughout the tree. Due to the blockage of the pathways of sap flow by fungal spores and the poisoning of plant tissues with toxic secretions, the vital activity of the root system is disrupted. But the greatest danger to apricot is represented by moniliosis (monilial burn and gray rot of fruits) and clasterosporium (perforated leaf spot).

Treatment and preventive treatment of wood from moniliosis

Monilial burn is typical for the spring period, when the apricot begins to bloom.... High humidity and low air temperature contribute to the onset and spread of the disease. Apricot trees in regions with a characteristic prolonged, cold spring, with fog and dampness, are at a high risk of being affected by moniliosis. For peduncles, the critical air temperature is to lower it to -1.5aboutC. The ovaries are affected by moniliosis and die when the temperature drops to -0.6aboutWITH.

Signs of a monilial burn:

  • flower petals become dark and then brown. Peduncles dry up and crumble;
  • leaves and young growths (mainly annuals) also turn brown and dry out;
  • in mature trees, the bark of the trunk and branches is covered with cracks, from which a large amount of gum is released.

During the development of the disease, the fungus releases toxins that kill apricot cells, and feeds on the already dead parts of the affected tree. An apricot with signs of moniliosis looks burnt, with dry branches and leaves.

Monilial (gray) fruit rot occurs in the summer, when the set fruits begin to pour and ripen. Fungal spores appear on fruits, first in the form of separate spots of light gray or brown color. Soon they merge into solid brown layers of mycelium. Within 5-7 days, apricots rot, dry out and fall off prematurely. Often, mummified fruits remain hanging on branches until late autumn. These diseased apricots are carriers of the fungal infection next spring.

Photo gallery: signs of various stages of moniliosis

Manifesting in the form of a monilial burn, the disease not only affects the fruits, but also causes significant damage to the vegetative parts of the apricot tree.

My experience in growing apricots for 17 years led me to the conclusion: if, for some reason, timely measures are not taken to destroy the fungal infection on the site, then in some years you can lose up to 40-50% of the crop. At the same time, an important component in the fight against fungi is not only the treatment of trees with fungicides, but also preventive maintenance. You cannot neglect the rules of agricultural technology, which imply the constant care of apricots. This is timely watering and feeding of trees, destruction of weeds, autumn digging of soil, loosening and mulching of tree trunks. Considering that fungal spores overwinter in plant debris (affected shoots and mummified fruits), in the fall, you should carefully rake and burn all fallen leaves, cut branches, and also be sure to remove dried fruits remaining on the branches. All this will allow trees to increase immunity, their ability to resist fungal infections.

Table: stages (cycles) of apricot treatment for moniliosis disease

Tank mix is ​​a composition of preparations for various purposes (insecticides, fungicides, etc.) mixed in one spray tank. It is used to treat fruit trees against diseases and insect pests. The tank mixture is characterized by a complex effect on fungi, viruses or insects. The use of such formulations makes it possible to reduce the consumption of each of the constituent preparations by 50% and to obtain a more effective result from processing due to the combination of the properties of the substances used in the tank mixture. In addition to protecting against diseases and pests, the tank mixture helps prevent diseases by stimulating apricot trees to increase their resistance to adverse factors.

Viruses and fungi that cause plant diseases tend to mutate and develop resistance (resistance) to a certain type of drug. The agents listed in the table are not recommended to be used for spraying all at the same time. They must be used alternating during the growing season of the apricot.

Treatment of apricot for clasterosporium disease (perforated spot)

Clasterosporium disease is a fungal disease. Like moniliosis, it can kill apricots if urgent measures are not taken to prevent healthy or treat diseased trees. The disease begins in late spring and early summer with darkening of the affected fruit and vegetative buds, which stop growing and do not bloom. Then the fungus spreads to leaves and young shoots, gradually covering the entire tree as a whole:

  • cracks form on the trunk, branches and shoots, turning into wounds and ulcers, from which gum is released;
  • brown spots 2–5 mm in size appear on the leaves, which quickly fall out, forming holes;
  • with severe damage, the leaves fall prematurely;
  • small reddish spots appear on the surface of the fruit, then they increase in size and take the form of convex pads of a dark brown color;
  • gradually the spots merge and turn into a solid crust of scab;
  • gum is also released from the wounds that cover the fruits.

Photo gallery: defeat of apricot by clasterosporium

If spores of the monilia fungus get into the wounds on the bark and fruits of the apricot, the tree is more likely to get sick with monilial (gray) rot. Most often, clasterosporiosis affects trees weakened by unfavorable external factors, damaged by harmful insects or varieties unsuitable for cultivation in this region.

The development of the disease is facilitated by:

  • the wrong choice of the planting site for the seedling (lowland, dampness, close standing of groundwater);
  • waterlogged heavy soil in the cultivation area;
  • climatic conditions unsuitable for this variety of apricot (cold spring and summer, heavy rainfall).

Video: clotterosporia (perforated spot) and its treatment

There are several ways to treat apricots for this fungal disease: spraying with fungicides or treating with copper-containing preparations. It is recommended to use systemic fungicides Skor, Topaz and Horus: either in the form of a tank mixture in various combinations, or each drug separately. Treatment with fungicides is more preferable and effective, since they are absorbed by plant tissues within 2-3 hours after spraying and are not washed off with water in case of precipitation. For spraying with copper-containing chemicals, 3-4% Bordeaux mixture (300-400 g per 10 l of water) or 1% copper sulfate (100 g per 10 l of water) is used. In both cases, the affected trees and soil are processed 4 times in the near-trunk circles:

  1. The first treatment is in the green cone phase.
  2. The second treatment is in the pink bud phase.
  3. The third treatment - 2 weeks after the second (after apricot flowering).
  4. The fourth treatment is carried out as needed (for example, if it rains).

It is necessary to stop treating trees with chemicals no later than 2-3 weeks before harvesting. As a preventive measure against clasterosporiosis, it is necessary to cut off damaged branches, carefully collect and burn all plant residues (dried leaves, fruits) of diseased trees. Sections should be treated with a mixture of 1% copper sulfate solution (or 3% ferrous sulfate solution) with lime. Cracks with gum that have come out must be cleaned to healthy wood, disinfected with 1% copper sulfate (100 g per 10 l of water), dried for some time and covered with garden varnish or Rannet.

Scab and ways to deal with it

Scab is not such a widespread and dangerous disease for apricot as moniliosis and clotterosporia, but it gives gardeners a lot of trouble and trouble. A symptom of the disease is the appearance on the leaves and fruits of a velvety brownish-olive or gray-black bloom. The leaves gradually dry up and fall off, the same happens with the annual growths affected by the disease. Then the fungus goes to flowers and ovaries. The fruits begin to grow unevenly, sores and warts form on their surface, they crack and lose their presentation. Manifestations of scab strongly affect the yield of apricot, the quality of fruits, and also contribute to a decrease in winter hardiness of trees and resistance to fruit rot by weakening their vitality.

Fruits affected by scab lose their presentation and slow down in development.

The initial period of the disease is considered the end of April-beginning of May, when the apricot blooms. At the end of May, secondary signs of the disease appear. High air temperature (20-25aboutC) during flowering and fruit setting, as well as 100% air humidity, when the formation of mycelium in the affected areas occurs within 1–1.5 days. If you take the necessary measures to treat apricot from scab, you can avoid this disease. Spraying is carried out in three stages:

  1. Before the apricot starts flowering (in the pink bud phase).
  2. After flowering (during the period of petals falling).
  3. One month after flowering (during the growth of ovaries and ripening of fruits).

For scab treatment, it is recommended to use the same systemic fungicides (Horus, Skor, Aktara) and copper-containing preparations as for spraying trees from moniliosis, and at the same time. Therefore, the treatment of apricot from moniliosis at the same time protects the plant from scab.

Video: processing apricot from scab

In order to prevent apricot scab disease, you should adhere to simple rules for tree care:

  • timely destroy fallen leaves and affected shoots after sanitary pruning;
  • regularly loosen the tree trunks during the growing season and dig up the soil in the fall;
  • spray trees with modern effective fungicidal preparations;
  • grow trees in the most suitable light and loose soils, in open, sunny and well-ventilated areas.

Delayed apricot flowering and protection against recurrent spring frosts

Apricots are among the earliest flowering fruit trees. The main period of their flowering is in May. It often happens that during this period a strong cooling occurs with a decrease in air temperature below 0aboutC. Even a slight frost up to -2aboutC causes damage to peduncles and their premature shedding.

The solution to this problem is to delay the onset of flowering of the apricot. To do this, in the period from mid-May to mid-June, the annual growth of overgrowing shoots should be shortened by one third or half (depending on the original growth length). As a result, new shoots with flower buds of the next year will begin to grow from the axils of vegetative leaf buds. In the spring of the next year, these buds will bloom 10-14 days later than the main flowers. If there is a sudden frost during the first wave of flowering and the main color is damaged, then in 2 weeks the buds of the second wave of flowering will bloom. Thus, the harvest will be only partially lost.

Photo gallery: spraying and pruning an apricot tree as a way to delay flowering

In spring treatments of apricot trees, to delay flowering, it is recommended to spray them with a 0.3–0.6% solution (30–60 g per 10 l of water) with DNOC insectofungicide. Treatment of the crown of a tree with this preparation in early spring slows down the development and blooming of flower buds for 8–17 days. Spraying should be done at the beginning of the budding period (before the green cone phase). To increase the winter hardiness of flower buds in late spring frosts, it is necessary to spray apricot crowns with a mixture of urea (700 g) and copper sulfate (50 g) diluted in 10 liters of water in the fall after the end of the growing season (after leaf fall). This treatment also allows you to delay spring vegetation and flowering for up to 7-10 days and avoid freezing of flowering trees.

Processing a damaged tree trunk

The bark of an apricot stem can be damaged as a result of a sharp change in air temperature during a sudden winter thaw (frost) or when a tree is affected by fungal diseases (gum disease). Through the damaged bark, an infection easily enters the wood tissue, which will only aggravate the painful condition of the plant. In any case, the site of injury must be treated without fail and create conditions for the tree for wound healing.

Apricot gum healing process:

  1. In the spring, clean the place of gum discharge on the apricot with a sharp disinfected knife to healthy tissue.
  2. Treat with a solution of copper sulfate (1 tablespoon per 1 liter of water). Leave the wound open to dry.
  3. After two days, spray the affected area with a strong solution of urea (700 g per 10 l of water).
  4. Cover the sore spot with a mixture of liquid mullein with clay (1: 1) or Rannet preparation, or garden pitch.

If the treatment is carried out in the spring (which is preferable), then by the end of summer and beginning of autumn the wound on the apricot will heal. If the damage is treated in the fall, then the next day the trunk should be whitewashed for the winter.

Spring processing of apricots from pests

From garden pests, apricot leaves and fruits can damage:

  • leaf aphid,
  • moth,
  • hawthorn butterfly,
  • leaflet.

But these insects cannot do significant harm to healthy, well-developed trees. Careful tree care, which consists in regular preventive treatment of apricots with fungicides and insecticides, weed control, timely harvesting of fallen leaves and whitewashing of tree boles to protect them from sunburn and wintering insects, ensures the immunity or high resistance of plants to diseases and pests.

Table: pests and control of apricot trees

Prepare the so-called tank mixture, for example from HOM (0.4%) and Fufanon (0.1%). This mixture can be sprayed on all berry and fruit plants. Such treatment is a preventive measure for many crops, and for some it is also eradicating. One spring treatment of the plant replaces 3-4 sprays in the summer. In spring, larvae of pests hatch from overwintered eggs and many adults emerge from the ground. Spring spraying against a complex of pests not only reduces their number, but also prevents the emergence of future generations of such pests as weevils, leaf beetles, sawflies, aphids, and ticks.

Types of preparations and methods of processing apricot trees with them

Currently, gardeners have at their disposal a large number of modern preparations for treating horticultural crops against insect pests and various fungal and bacterial diseases. These are chemicals that are classically used in horticulture (various vitriol and Bordeaux mixture), as well as fungicidal and insecticidal preparations of various principles of action - from contact to biological.

What and when to spray fruit trees

Hello dear friends!

Nobody argues, environmentally friendly fruits are great! But their cultivation is laborious, it takes a lot of gardeners' time, and not everyone can do it.

No matter how much breeders fought, creating new, disease-resistant varieties and hybrids of plants, there are still no absolutely immune to harmful pathogens, despite all the advertising assurances of individual sellers of planting material. And all because the development of diseases and the spread of pests largely depends on the climatic conditions during the growing season, and the weather, as you know, is unpredictable.

So it turns out that the gardener should always be ready for the appearance of dangerous infections and all kinds of gluttonous insects that encroach on his harvest. Well, if the wintering (last year's) forms are preserved on the site, an irreconcilable struggle between the gardener and the "freeloaders" will take place for the fruits and berries.

When, what, how and from whom to save fruit trees and shrubs, an indicative schedule for protecting the garden from pests and diseases will help.

How and when to spray fruit trees and shrubs:

Spraying apples and pears

March - early April. Hope you have done your early spring garden work. This includes cleaning up old bark and eliminating wintering nests of hawthorns and golden-tails. When pruning trees, it was necessary to cut out annual shoots with hibernating eggs of the ringed silkworm.

April. Upon reaching positive temperatures of 4 - 6 degrees - the treatment of the apple tree from the apple flower beetle. Overlay of hunting belts on boles with Pestifix glue.

At the end of April - processing of the garden from stocks of scab and fruit rot. To do this, during the green cone period (the period of swelling of the kidneys), 1% Bordeaux mixture (100 grams of copper sulfate + 100 grams of lime per 10 liters of water) should be used for spraying. Substitutes are also suitable - the drug "HOM" (40 grams per 10 liters of water), "Kartotsid" (40 - 60 grams per 10 liters of water), copper sulphate (100 grams per 10 liters of water), "Abigapik" (50 grams per 10 liters of water).

On the pear, at the beginning of bud break, against ticks, sprinkle with "gray colloidal" (50 - 100 grams per 10 liters of water), "Neoron" (15 - 20 milliliters per 10 liters of water).

May. During the flowering period, it is possible to use biologically active preparations against the caterpillars of leaf rollers, such as Lepidocid (20-30 grams per 10 liters of water), Biotoxibacillin (40-80 grams per 10 liters of water), Fitoverm (1.5 - 2.0 milliliters per liter of water).

Immediately after the flowering of apple and pear trees, in the presence of scale insects, treat the trees against vagrants with Karbofos (75 - 90 grams per 10 liters of water). Spraying with "Aktara" preparation, preparation No. 30 is possible.

In the presence of upper-sided or lower-sided mining moths, it is possible to use "Fozolon" or "Rogora-S".

Against scab and powdery mildew, you can use the preparations "Skor" (2 milliliters per 10 liters of water) or "Topaz" (2 milliliters per 10 liters of water).

At the end of May, with the sum of effective temperatures above 10 degrees, corresponding to the moth's summer, it is recommended to treat apple and pear trees in the evening (from 19 to 24 hours) with insecticides. To do this, you will need one of these drugs: Kinmix (2.5 milliliters per 10 liters), Karate (2 milliliters per 10 liters), Karbofos (75 - 90 grams per 10 liters), Insegar ( 5 grams per 10 liters), "Calypso". Pome crops can be re-sprayed after 14 to 16 days.

It is advisable to use Fitoverm (1.5 - 2 milliliters per 1 liter) and Hostaquik (2 milliliters per 10 liters) against aphids.

June. In the first summer month, under unfavorable conditions, a second treatment against the codling moth may be necessary. The preparations are the same as in May. In order to prevent addiction, it is better to alternate the drugs.

In the presence of ticks, trees should be treated with Neoron (15 - 20 milliliters per 10 liters of water), Colloidal sulfur (50 - 100 grams per 10 liters of water).

Against scab, apply "Skor" (2 milliliters per 10 liters of water), "Agat-25" (1.2 grams per 6 liters), copper sulfate (15 - 20 grams per 10 liters of water), "Impact".

July. This month, seed crops are treated with a weak solution of copper sulfate (5 - 10 grams per 10 liters of water). This technique has a deterrent effect - there will be no weevils on the trees.

All synthetic treatments should be discontinued 20 days before harvest.

So, we figured out how and when to spray fruit trees of pome crops.

Spraying stone fruit crops

We include cherry, sweet cherry, plum, blackthorn, apricot, peach to stone fruit crops. They have their own tree processing schedule.

April. During the period when buds begin to bloom, against fungal diseases, it is necessary to treat trees with copper-containing preparations. Let me remind you: this is a 1% Bordeaux mixture, copper sulfate (100 grams per 10 liters), "Kartotsid" (60 grams per 10 liters) and copper oxychloride (40 grams per 10 liters), it is permissible to use "Kuprozan", "Khomycin" according to the instructions ...

May. After flowering stone fruit crops, it is necessary to carry out repeated treatments with copper-containing preparations. Immediately after flowering, plum trees should be sprinkled against the plum thickfoot with karbofos (75 - 90 grams per 10 liters of water) or Decis (2 milliliters per 10 liters of water), etc.

June. At an air temperature above + 10 degrees, the first treatment is carried out against the plum moth with karbofos (75 - 90 grams per 10 liters) and "Fozolon" (according to the instructions). The second treatment is possible with the same preparations after 12-14 days.

Treatment of cherries against cherry flies (approximately the second half of June) with coniferous extract, infusion of garlic, wormwood decoction or preparations "Cymbush" (1.5 milliliters per 10 liters of water), "Kinmix" (2.5 liters per 10 liters of water), etc. ...

From scab, coccomycosis, moniliosis, clasteroporia, it is necessary to treat stone fruit cultures with copper preparations. In addition to 1% Bordeaux mixture and copper sulfate (100 grams per 10 liters), it is possible to use "Kartotsid" (60 grams per 10 liters of water) or copper oxychloride (40 grams per 10 liters of water).

July. Spraying trees with "Lepidocid" (20 - 30 grams per 10 liters of water), "Bitoxibacillin" (40 - 80 grams per 10 liters of water), "Fitoverm" (1.5 - 2.0 milliliters per 10 liters of water) against larvae cherry slimy sawfly.

All synthetic treatments should be discontinued 20 days before harvest.

Types of spring treatments

There are 3 types of spraying. Each of them has its own characteristics that must be taken into account, otherwise the manipulation will harm the plant.

Eradicating

The main task is the destruction of pests that are in the wintering stage. The use of the following groups of drugs is assumed:

  • tick-killing acaricides
  • fungicides, which are antifungal agents
  • insecticides that help fight insects.

All of these drugs are very toxic to humans and animals. When using them, you need to protect the skin and respiratory tract.

The procedure is carried out 1 time per season - in the absence of wind, in cloudy weather. If rain is expected, the processing of the tree should be postponed for 1-2 days.

Preventive

It is assumed the use of drugs less toxic to humans. They are dangerous only for bees, and it is advisable to use them after flowering.

Flowering delay treatment

The procedure is carried out in regions with long winters, when there is a risk of freezing of flower buds. Prolongation of the dormant period increases the regularity of fruiting.

For spraying, which is carried out before starting the process, a steep saline solution is used. It is prepared at the rate of 400 g of salt / 10 l of water. After applying it, the flowering of the tree will shift by 1-1.5 weeks.

The use of urea is also permitted. It can be combined with copper sulfate and Bordeaux mixture.

  1. Mulch the tree with sawdust. First you need to sprinkle the near-trunk circle with snow, then tamp the layer. Next comes the source material, then snow again. This "puff" freezes well and does not melt for a long time.
  2. Spill the apricot with water. The procedure is carried out in the fall, before the start of frost. Each tree is thoroughly watered to freeze the water during the winter.


Spraying apricots in early spring during flowering

With the arrival of spring, more and more people rush to summer cottages. The time for sowing and planting has not yet come, but the treatment of the garden from diseases and pests has already begun. You need to start it just when the first rays of the sun begin to warm up the nascent life inside the trees, under their bark and on its surface.

The future harvest also depends on the processing of the garden and its timely spraying. Some larvae start their life earlier, others later, which is why there is a calendar for pest control.

There is an interesting article on what interesting varieties of multi-colored apricots are.

How to which trees are best to graft apricots.

In early spring, before the buds swell, it is necessary to prune trees, thinning their branches (this will make it easier to fight pests, and in the future, less branching will contribute to their slow reproduction). At this time, it is necessary to remove green lichens, larvae of caterpillars and other egg-laying with a metal brush.

Apricot buds bloom

When the buds open, a 3% Bordeaux liquid is processed. It includes the following components:

  • copper sulfate - 300 gr
  • quicklime - 300 gr
  • water - 10 liters.

Dilute all ingredients in different containers. Copper sulfate dissolves in 1 liter. lukewarm water in a non-metallic container. In the second, extinguish the lime in the same one liter of water.

Next, dilute the resulting solution to 10 liters, stirring constantly. The prepared mixture must be consumed on the day of dilution, otherwise its quality will deteriorate.

2 weeks after the flower petals fall off, spraying with 1% (lime and vitriol, 100 grams per 10-liter bucket of water) Bordeaux liquid or its substitutes (copper oxychloride, KAPTAN, Tsineb) is performed. In order to fight different pests, mixtures of different solutions are used.

About 20 days after spraying, repeat spraying to consolidate the result. In general, it is recommended to repeat spraying every month until autumn.

Summer processing of the garden is equally important in spring. The less we let the pests multiply, the less our garden will hurt.

Spraying trees in autumn

Before fruiting, it is recommended not to spray the trees, but to start pouring water over them with a hose. This will give a crop without chemicals, and with the pressure of water, you will partially knock down pests and the remnants of past spraying.

After you have already harvested, do not stop processing the trees, because the pests will not fall asleep for the winter soon, which means that it is worth processing the trees until late autumn. And after the leaves fall, when night frosts begin, pest control can be suspended until next spring.

Regular processing of trees is the key to a healthy future harvest. Take care of your garden and it will reward you generously!

Below, we suggest you watch a video on how to properly spray and process apricot trees in spring:


Preparations for processing apricot

Consider the most popular, tested and effective drugs used for processing apricots.

Generic pesticides

These drugs are used for eradicating treatments.

It is the most potent drug, a 60/40 mixture of ammonium salt and dinitroorthocresol.

DNOC is a potent toxic drug for eradicating treatments, used no more than 1 time in 3 years

When using it, special care should be taken - according to the instructions, DNOC cannot be used near residential buildings (no closer than 1-2 km), the permitted processing interval is once every 3 years. Its eradication and protective effect extends to all known pests and pathogens of fungal diseases and lasts for 30 days. It can be produced under the names:

  • Celinone
  • Synox
  • Hedolite
  • Dinosal
  • Dinon
  • Cresoton.

Before use, DNOC powder is diluted in two liters of warm water, after which the volume is brought to 10 liters and the trunk and crown of the apricot are sprayed.

Nitrafen

This drug is just as effective as DNOC and is usually used in years when DNOC is not being used. Produced in a concentrated liquid form, before use, 150-200 g of the paste is diluted in a bucket of water.

Nitrafen is used in those years when DNOC is not used

Copper sulfate (copper sulfate)

Copper sulfate belongs to the old and proven plant protection products. It can be used both for eradicating treatments, and for medical treatments, as well as for the purpose of disinfecting sections, wounds, and tools. At the same time, the copper deficit is replenished, if any. Depending on the direction of use, the concentration of the solution is selected:

  • for eradicating treatments and disinfection - 3-5% (300-500 g / 10l)
  • for the treatment of fungal infections - 0.5-1% (500-100 g / 10l)
  • for foliar dressing - 0.05-0.1% (50-100 g / 10l).

Copper sulfate is used for eradicating and therapeutic treatments, as well as for disinfection.

Bordeaux liquid

Since copper sulfate has the property of increasing acidity, which is not always beneficial for plants, it is neutralized by adding slaked lime to the solution, thus obtaining the so-called Bordeaux mixture. For this, two solutions are prepared in different containers:

  • 300-500 g of copper sulfate is dissolved in 5 liters of water
  • 300-500 g of lime is also dissolved in 5 liters of water.

Then the first solution is poured into the second in a thin stream, stirring continuously, after which it is filtered and used for processing. The solution is not stored and is prepared immediately before use.

Bordeaux mixture - a proven fungicide

Inkstone

It does not have such a broad spectrum of activity as copper. On apricot, it is used to combat mosses, lichens, gray rot, clasternosporia. It is also an excellent remedy for combating chlorosis caused by iron deficiency. The usual concentration for eradication treatments is 4% (400 g / 10L).

On apricot, ferrous sulfate is usually used to combat mosses, lichens, gray rot, clasterosporium

Urea (urea)

This effective mineral nitrogen-containing fertilizer is also used for spring treatments of apricot against scab, spots, aphids, weevils, copperheads, etc. For these purposes, prepare a solution of 500-700 grams of the drug in a bucket of water.

Urea is used for spring treatments of apricot against scab, spots, aphids, weevils, copperhead

Fungicides

To combat fungal diseases of apricot, modern preparations can be recommended.

Horus

The active ingredient in Chorus is cyprodinil. The drug acts on the wintering stage of pathogenic fungi, and it is effective only on young leaves in the temperature range of + 3-22 ° C. Therefore, it is used in the spring for preventive and therapeutic treatments. Horus has a protective duration of 7-10 days and a waiting period of 14 days. Concentration for processing apricot - 2 g / 5 l.

Chorus is used in the temperature range + 3-22 ° C

Strobe

The active ingredient of this unique broad-spectrum fungicide is kresoxim-methyl. Its uniqueness lies in the fact that it almost instantly blocks the multiplication of infection in all parts of the plant. Strobi effectively heals the infected plant and prevents the spread of disease by inhibiting sporulation and mycelium growth. Perfectly fights spotting, powdery mildew, scab, rust. It is used at low temperatures - from +1 to 20 ° C. Retains a protective effect for up to 45 days, does not accumulate in the soil and fruits. The waiting period is 25 days. Consumption rate for apricot processing - 2 g / 10l.

Strobi effectively heals the infected plant and prevents the spread of disease by suppressing sporulation and mycelium growth

Tsineb

Once on the plant, the drug stops metabolic processes in the fungus for a short time, thereby blocking its development. Protects the plant for a period of 10 to 15 days. Effective against many fungi affecting apricots, except powdery mildew. It is addictive and can be used no more than 3 times. To prepare a working solution, 40 g of powder is preliminarily dissolved in a small amount of water, then bringing to 10 liters.

Once on the plant, Tsineb for a short time stops metabolic phenomena in the fungus, which blocks its development.

Abiga Peak

The drug is a 40% stock solution of copper oxychloride. Like other copper-containing preparations, Abiga Peak is effective against many apricot diseases, including:

  • moniliosis
  • scab
  • powdery mildew
  • clotterosporium disease, etc.

For processing apricot in a bucket of water, dilute 40-50 g of the drug, apply up to four times. The duration of treatment is 15-20 days.

To process the apricot in a bucket of water, dilute 40-50 g of the drug, apply up to four times

Insecticides
