How to get rid of aphids on apricot tree


9 Types of Apricot Tree Pests

If you are planning to plant an apricot tree, it is important to know all about apricot pests. A successful home orchardist knows what to look for in terms of pests and diseases and checks their fruit trees regularly.

If you have an apricot tree in your garden, keep an eye out for signs of pest infestation. Early detection can make all the difference in the yield and lifespan of your tree.

In this article, we’ll talk about some of the most common apricot tree pests and how to get rid of them.

How Do Apricot Tree Pests Hurt Your Tree?Knowing about apricot tree pests will help you to enjoy a harvest of ripe, juicy apricots each year.

Apricot trees can be affected by a variety of insects and pests. Some of these cause only superficial damage, such as pitted fruit or withered leaves. Others can damage your tree extensively, destroying the year’s fruit crop, spreading to other trees in your garden, or even destroying your apricot tree permanently.  

1. Sap-Feeding Insects

Sap-feeding insects are not a single, distinct species. Rather, the term refers to a variety of pests that infest trees (often fruit trees like apricots) and drain them of their sap.

Sap-feeding insects are some of the most common pests you will find in your garden and are a regular sight on apricot trees. In general, the term refers to mites, aphids, mealybugs, and scale insects. 

One big problem with sap-feeding insects is that they can be hard to spot. They are extremely small and good at hiding, often disguising themselves in the soil or on the underside of leaves. Experienced gardeners will tell you it takes some time to notice the telltale signs of an infestation. 

How Can They Hurt Your Tree?

Sap-feeding insects, as their name implies, literally drink the sap from your tree. This can eventually cause the apricot tree’s leaves to turn yellow and fall off prematurely, weakening the tree and reducing its ability to produce fruit while also making the tree more vulnerable to other pests and disease.  

Other telltale signs of an infestation include sticky residue on the trunk or leaves or a large number of ants around the tree. 

How To Get Rid Of Sap-Feeding Insects

One of the best ways to get rid of sap-feeding insects on your apricot tree is to apply neem oil and horticultural oil every week for the growing season after you first spot the insects. Insecticidal soap works well against certain sap-feeding insects, including aphids and mealybugs.

2. Mites

Mites fall under the broad category of sap-feeding insects. However, because they affect the tree in unique ways and need a unique control method, they have been included in a separate category.

What Are Mites?Red spider mite on strawberry plant.

Mites are tiny arachnids that feed on the sap of trees. They do not cause sap “bleeding” like other similar insects. They are extremely hard to spot on their own due to their tiny size. The best way to diagnose a mite infestation is spotting the distinct webs that they leave behind wherever they feed.

How Can They Hurt Your Tree?

Mites can cause extensive damage to an apricot tree. They drain it of vital nutrients, causing leaves to wither and fall off prematurely. If they infest a tree during a time of new growth, they can wreak havoc on the vulnerable new shoots, leading to deformed or ruined fruit. 

How To Get Rid Of Mites

Getting rid of mites is a dedicated process, but thankfully it is straightforward. In mild cases, you may be able simply to hose them off your tree. You can also apply a 1-2 percent insecticidal soap during the spring, when apricots first begin to fruit.

3. Foliage-Feeding Caterpillars

Like Sap-Feeding Insects, Foliage-Feeding Caterpillars are no single pest. Rather, the term refers to any and all caterpillars that infest fruit trees and attack foliage.

What Are Foliage-Feeding Caterpillars?Eastern Tent Caterpillars.

Foliage-Feeding Caterpillars can refer to any one of several caterpillar species. Some common types include leafrollers, sawflies, and cabbage loopers. These vary in detail, but all of them essentially attack your tree in the same way. 

Unfortunately, caterpillars can be difficult to spot in a fruit tree. They are very good at hiding in leaves and branches while feasting on its nutrients. 

How Can They Hurt Your Tree?

Caterpillars not only attack and eat apricot tree leaves, but also the fruit. They can destroy a fruit crop by eating through the outside skin and burrowing into the fruit. Meanwhile, they can also cause your apricot tree to turn yellow and drop leaves prematurely as they eat them.

How To Get Rid Of Foliage-Feeding Caterpillars

The first and most basic step you should take is to remove any visible caterpillars by hand. Take them out of the area so that they don’t reenter your tree. Then, apply a pesticide called bacillus thuringiensis. This is an extremely effective poison that kills caterpillars but does not affect the leaves or fruit of the apricot tree. Because it fades quickly from leaves, you will need to reapply it every few days to catch any new larvae or remaining caterpillars.

4. Borers

Borers are larvae from certain types of insects and moths. They can be an extremely difficult pest to treat, since, as their name implies, they bore into the trunk and destroy the tree internally. Because of this, prevention is usually the preferred method of avoiding borers. 

What Are Borers?An adult Apricot-Peachtree Borer.

Borers are the larvae of certain species of beetles and moths. These insects lay their eggs on fruit trees. When they hatch in the spring, borers tunnel their way into the tree, feasting on its nutrients. 

How Can They Hurt Your Tree?

Borers can cause severe damage to an apricot tree. By creating tunnels inside the tree, they can drain it of its nutrients, eventually leading — in severe cases — to tree girdling. Girdling causes a tree to die altogether. Even moderate borer infestations can cause damage, including stunting a tree’s growth. 

How To Get Rid Of Borers

While borers are extremely difficult to get rid of once they’re in your apricot tree, the good news is that they are much simpler to prevent. The insects that lay these eggs choose trees that are in distress. By protecting your apricot tree from wind and sun damage and keeping it well-nourished with good soil, water, and fertilizer, you’ll do a lot to protect your apricot tree. 

Pruning your tree in the winter will get rid of any eggs that have been laid there. Make sure to remove and destroy any pruned branches or foliage so that larvae don’t reinfest your tree.

5. Aphids

What Are Aphids?Green aphids.

Aphids are tiny, bright green insects that fall under the broad category of sap feeders.They can infest trees multiple times a year, causing different types of damage whenever they do. They suck juices from fruit trees, draining them of vital nutrients. 

How Can They Hurt Your Tree?

Aphids are a unique pest because they tend to infest apricot trees in the spring, then move to different fruit trees in the summer and back to apricots in the autumn. In the spring, their feeding can slow the growth of new shoots. In the autumn, they can cause fruit to become deformed or malnourished. 

Aphids also leave sticky residue called honeydew behind. This can attract fungus and mold, causing your tree to become infected.

How To Get Rid Of Aphids

Your best course of action is to take care of aphids before the population gets too large. In mild infestations, it may be enough simply to spray your apricot tree with a jet of water from the hose to remove aphids. Avoid over-watering or over-fertilizing your tree, as this can attract the pests. Insecticides applied later in the season can be effective.

6. Japanese Beetles

What Are Japanese Beetles?

Japanese beetles are a common garden pest that can cause a huge amount of destruction. These shiny, green-headed beetles eat their way through fruits and foliage, causing extensive damage. 

How Can They Hurt Your Tree?

Japanese beetles are constantly eating, so you will spot their damage right away. Almost immediately, you’ll notice large holes in foliage and even clusters of beetles on fruit as well. Though they can destroy a garden, they can also be controlled more easily than some types of apricot tree pests.

How To Get Rid Of Japanese Beetles

To get rid of Japanese beetles, adopt a three-step approach: remove them manually from your tree, weed extensively to avoid attracting them, and apply pesticide.

7. Leafroller

What Are Leafrollers?A Leafroller caterpillar on a green leaf,

Leafrollers are small caterpillars that infest trees like apricots. The telltale sign is leaves that are curled in on themselves, creating a nest that protects the caterpillars from predators.  

How Can They Hurt Your Tree?

The good news is that leafrollers don’t usually cause a huge amount of damage. They certainly cause cosmetic damage and can stunt the growth of your tree in severe infestations. However, it takes a lot to get to that point.

How To Get Rid Of Leafrollers

Usually, it is sufficient to remove leafrollers manually and cut away the leaves that are affected. If the infestation is severe, apply bacillus thuringiensis to kill the caterpillars. 

8. Oriental Fruit Moth

What Are Oriental Fruit Moths?An adult Codling Moth, very similar in appearance to an Orient Fruit Moth.

Oriental fruit moths are moths that lay their eggs in many varieties of fruit tree, including apricots, plums, peaches, and more. The larvae burrow into the fruit, eating it from the inside.

How Can They Hurt Your Tree?

Oriental fruit moth larvae can destroy a fruit crop by eating it from the inside. This usually happens starting in the third or fourth generation. Early generations attack new shoots, but as they continue laying eggs, they can devastate a fruit tree. 

How To Get Rid Of Oriental Fruit Moths

The good news is that there is usually plenty of time to recognize and eliminate an Oriental fruit moth infestation. Fruit damage rarely happens until later generations. During early infestations, you can greatly reduce the infestation by setting pheromone traps.

9. Plum Curculio

What Are Plum Curculio?

Plum curculio are snout-nosed beetles that lay their eggs in fruit trees. The larvae burrow into the fruit, causing extensive damage. 

How Can They Hurt Your Tree?

Plum curculio larvae can destroy apricots from the inside, eating holes in the skin. The fruit becomes pitted and misshapen and may fall off the tree prematurely. 

How To Get Rid Of Plum Curculio

The first step in getting rid of plum curculio is manually removing any visible insects. Shake the tree to remove affected fruit and clean up surrounding soil. Destroy the fruit and foliage that contains larvae. In severe infestations, you may need to apply insecticide.

Spraying For Apricot Tree Pests 

You should spray apricot trees annually in the autumn after the fruit has been harvested. This is also a good time to prune your tree to remove any nesting larvae. There are many commercial insecticides that are well-suited to apricot trees, including both standard and natural varieties.

FAQ

How Can I Increase My Apricot Yield? 

The best way to increase your apricot yield is to provide it with proper care and keep an eye out for pests and disease. Most apricot trees are self-fertile, but you can increase the amount of fruit from a single tree by planting a second one nearby. 

When Should You Spray Apricot Trees For Pests?

The best time to spray apricot trees for pests is in the autumn and the winter. This will kill any eggs that have been laid for overwintering.

Conclusion 

It is important to check your apricot tree regularly to make sure it is growing well and is free from pests and disease. Meanwhile, learn the telltale signs of infestation so that you can spot problems early and get started on treating them. Doing so will reduce your risk of losing your fruit crop or even your entire tree.

Apricot Tree Bug Control - Learn About Common Pests On Apricot Trees

There’s nothing like eating a fresh, ripe apricot straight from the tree. Gardeners invest years in bringing this pivotal moment to fruition, nurturing their apricot trees and fighting off the diseases and pests that can hamper their apricot-growing efforts. There are many types of pests on apricot trees, but most can be controlled without using potentially dangerous insecticides. Let’s take a look at some common apricot tree insects and how to treat them.

Below are some of the most common insects that cause apricot tree problems.

Sap-Feeding Insects

An important keystone to successful apricot tree bug control is recognizing the sap-feeding insects, an overwhelmingly common group of pests. These insects hide on the undersides of leaves or disguise themselves as waxy, cottony, or wooly bumps on stems, shoots, and twigs while feeding directly on plant juices.

Aphids, mealybugs, and a variety of scale insects are some of the most common apricot tree insects, but you may see signs of their feeding like yellowing and dropping leaves, sticky honeydew on leaves, or ants on your trees long before you notice sap-feeding pests. Weekly sprays of horticultural oil and neem oil work well for all of these slow-moving or immobile pests or you can use insecticidal soap against aphids and mealybugs.

Mites

Mites are tiny, sap-feeding arachnids that are difficult to see with the naked eye. Unlike sap-feeding insects, they don’t produce honeydew, but may weave thin strands of silk where they are actively feeding. Mites appear as tiny dots on the undersides of leaves that have become stippled or spotted, or where leaves are dropping prematurely. Eriophyid mites cause unusual swellings where they’ve been feeding on leaves, twigs, or shoots.

You can often prevent apricot tree problems caused by mites by keeping dust levels down, spraying leaves frequently with a water hose during dry weather, and refraining from the use of broad-spectrum insecticides that kill mite predators without controlling mite populations. Where mite colonies are problematic, a few weekly applications of horticultural oil or insecticidal soap will knock them back.

Foliage-Feeding Caterpillars

No discussion about controlling insects on apricots can be complete without at least a mention of the many caterpillars that eat leaves and damage fruits by chewing holes through the peel. Leaf-rolling caterpillars fold apricot leaves over themselves to form distinct, silk-bound nests where they feed from the inside. As leafrollers grow, they expand their nests, sometimes incorporating flowers or fruits. Other foliage-feeding caterpillars remain exposed, but hidden in the canopy while they feed.

Bacillus thuringiensis, commonly known as Bt, is considered the best control for widespread caterpillar outbreaks. This bacteria-derived stomach poison is short-lived on leaves, so must be reapplied every two or three days until all caterpillar eggs have hatched and larvae have had an opportunity to feed. Small caterpillar populations should be picked off of trees.

Borers

The larvae of a few beetles and moths become severe pests on apricot trees when they bore into trunks, twigs, and branches to feed on the sapwood that grows just below the bark layer. Large populations of tunneling larvae may eventually girdle trees, interrupting the flow of nutrients to branches and leaves where growth and photosynthesis take place. Without the ability to process the raw materials drawn up from the roots, trees become stunted, stressed, or die depending on the location of the girdling.

Borers are among the most difficult to control of apricot tree insects because they spend much of their lives inside the tree itself. Pruning out infested limbs in the winter and destroying them immediately can break the life cycle of borers that are not infesting the trunk. Otherwise, good support for your tree in the form of proper watering and fertilizing is often the only thing you can do to prevent further penetration by larvae- adult borers only lay eggs on severely stressed, injured, or sunburned trees.

Control methods Many associate it with childhood memories. But, as with other fruit trees, aphids on apricots are a fairly common phenomenon. The tree can be affected by peach aphids, less often reed aphids. The presence of these harmful insects contributes to the weakening of the immune system and the appearance of soot fungus. How to deal with aphids on apricots, the answer to this question is of interest to many gardeners.

Signs of the appearance of aphids

An apricot tree infested with aphids is easy to identify:

  1. Flowers and leaves on it are covered with a white coating, like cobwebs.
  2. Leaves curl, wilt and fall over time. Shoots are bent and do not develop.
  3. Fruits and buds do not ripen.
  4. Small pests in gray, black, brown or green are visible on the reverse side of the leaf.

The presence of these symptoms indicates that the affected plant needs protection.

Aphids on apricots

Methods of control

There are several ways to get rid of aphids on apricots:

  • physical and biological effects;
  • chemical preparations;
  • folk remedies.

Consider each option separately.

Physical impact

This method of struggle is acceptable only in the initial stages, when the tree is still slightly attacked by insects. It involves manual collection of aphids or the use of pressurized water. The process is time-consuming and not always effective, requiring constant repetition. If the area of ​​\u200b\u200bthe garden is large, then it is not necessary to talk about a complete victory over aphids using this method.

Although the biological method does not give a great effect, it is quite acceptable with a slight accumulation of aphids. It consists in attracting birds (sparrows, tits, linnets) and beneficial insects (ladybugs, or lacewings). To do this, sow umbrella plants (dill, parsley, lavender, thyme or fennel), and also put out feeders with grain.

Use of chemicals

This method is the most effective. It is enough to spray the tree with a pesticide several times, and the problem will be solved. But along with the pests, beneficial insects will also die. In addition, chemical treatment is not recommended during the period of budding and flowering of apricots.

The most effective products are those that are just appearing on the market. Manufacturers claim that insects have not yet developed immunity to them. Among the many preparations, one can single out:

  • Aktara;
  • Alatar;
  • Fitoverm;
  • Confidor Maxi;
  • preparation Tanrek;
  • Chorus;
  • Spark agent;
  • Nitrafen.

Note!

Treatment with these preparations is carried out on a fine calm day. Moreover, the apricot should be sprayed under high pressure - it is necessary that the chemical solution gets on the underside of the leaf.

Folk remedies

Folk remedies for aphids may not be as effective as chemical treatments. But in the initial stages of tree infection they give a good result. There are several effective recipes for how to process an apricot from aphids.

Methods for controlling aphids

Soap solution

According to experienced gardeners, soap solution is one of the most effective. In 10 liters of water, it is necessary to dissolve 2 tbsp. l. liquid soap. The resulting solution is irrigated with apricots infected with aphids.

Use a mixture of soap and ash for maximum effect. For 10 liters of water you need: a liter jar of ash and 40 g of liquid or grated soap (can be replaced with dishwashing liquid). The mixture is infused for 2 days. The resulting infusion is sprayed with apricot every 10 days.

Interesting!

Laundry soap can also be used in combination with kerosene: the same amount of water and soap requires 80 g of kerosene. Exceeding the indicated doses may cause leaf burn.

Garlic

Aphids are also afraid of garlic smell. 30 g of crushed garlic insist in 1 liter of water throughout the day. The mixture is filtered and used to spray infected plants.

Onion

Quite effective against aphids is an infusion of onion or onion peel. Per liter of water, you need 15 g of onion chopped to a mushy state or 6 g of onion peel. The composition is placed in a hermetically sealed container and infused for at least 5 hours. Then it is filtered and used to irrigate infected trees.

Grasses

Does not tolerate aphids and smells of many herbs. Repellent plants include: chamomile, nettle, calendula, celandine or wormwood. Of these, decoctions are prepared based on 1 liter of boiling water 100 g of the product.

Other folk remedies

Other popular folk remedies will also help get rid of aphids:

  • ammonia;
  • soda;
  • milk and iodine;
  • Coca Cola;
  • vinegar;
  • mustard;
  • vodka;
  • Green soap;
  • birch tar;
  • tobacco;
  • boric acid.

Only careful inspection and timely processing will help get rid of the pest and save the crop.

Pests of Aphids "How to deal with the aphids


We get rid of folk and chemical methods

garden appears closer to summer and attacks young leaves and flowers. It feeds on the sap of plants, which leads to a weakening of the tree and the loss of part of the crop.

Prophylaxis . Spraying trees with chemicals from pests and diseases begins as soon as the snow melts and the temperature is above zero.

Pests overwintering in the bark are helped by copper sulfate, Bordeaux liquid, urea .

The second time the garden is sprayed with against pests during budding. It's around February-March.

The third wave of treatment - before flowering.

Fourth - in the "rose bud" stage, when the flowers on the tree are about to bloom.

Aphids brought by ants . They carry it throughout the garden, arrange places for it to winter, and even protect it from other insects. In the second half of summer, aphids appear, which migrate independently, flying from plant to plant.

Ants bring aphids to trees

How to protect a tree from ants

Install a hunting belt . Wrap a skein of bandage up to 10 cm wide around the tree. Soak the bandage with birch tar. Tar has an oily texture, which is practically not washed off by rain and does not fade in the sun. If the summer turned out to be rainy, then you can soak the bandage again as needed. This option works all season and is very effective.

Scotch or fly tape . It works on the same principle as the hunting belt. It is more convenient to work with double-sided tape, but ordinary tape can also be used. Wrap around the trunk several times with the sticky side out. Ants simply will not physically be able to get onto a tree and bring aphid larvae onto the branches.

The disadvantage of method is that you need to periodically change the tape or fly tape. BUT! Trapping belts will not protect the tree from flying aphids in the middle of summer.

Folk remedies for aphids on a tree

Aphids on cherries and cherries multiply rapidly during the ripening of the crop, when it is no longer possible to apply chemical preparations. Natural and very inexpensive means to combat aphids will come to the rescue.

Spray trees with ammonia . From aphids on trees, ordinary ammonia from a pharmacy helps well.

For 10 liters of water 40 ml of ammonia + 2 tablespoons of liquid soap or shampoo. The ideal option is liquid tar soap .

It is possible to spray trees with ammonia from pests in spring and in the first half of summer. Ammonia is also a good foliar fertilizer.

Treat trees with soda ash. 2 tablespoons of soda ash (not drinking) + 1 liter of water + a tablespoon of soap (liquid soap, shampoo, dishwashing detergent, laundry gel). This is an effective remedy for powdery mildew. You can process the entire garden and bushes already with fruits.

Baking soda helps get rid of aphids on trees: 1 tablespoon of baking soda per liter of water. Spray several times with an interval of 5 days.

Mechanical methods:

#1 . If there are very few aphids, just gently crush it with your hands, cut off the affected leaves.

#2. Not 100% cleaner, but effective: wash with a strong hose of water . We managed to save the cherry so much when the berries were almost ripe on it.
