How to get rid of scale insects on a lemon - affordable and effective methods. What are the pests of tangerines

Spider mite on indoor lemon is a common pest. It is very small and difficult to see with the naked eye. It is better to have a magnifying glass for such purposes. The spider mite feeds on the juice of lemon, tangerine and other citrus leaves, making small holes in the leaves. Gradually, such leaves turn yellow, the tips dry up and the leaves fall off.

As I said, a tick on a lemon can not be detected immediately, and most often we start sounding the alarm when the whole plant is already in the web. This is already a late stage of infection. It is important to learn to "see it" on early dates infections. Take a cotton swab dipped in alcohol or vodka and wipe the leaves of your citrus from the back and outside. On them you can see very small insects.

Fighting spider mites on citrus plants.

To get rid of the spider mite, it is important to be patient and stock up on drugs against this pest. You will need to buy several different drugs, because. a tick can "get used" (to develop immunity) to one remedy.

There are chemical and natural preparations in the fight against spider mites and they are called acaricides. When choosing a specific drug, you need to know what it is, because. if we took chemical drug, it must take from 2 or more months before the poisons disintegrate in the plant, and only after that we can remove the fruits and eat them. Or we must sacrifice the fruits to save the plant.

Natural remedies are safe, or conditionally safe, and can usually be harvested the next day or a week later.

Where to begin?
- Kam we have already said above, the first stage of purification is to wipe all the leaves and stems, lemon branches with a cotton pad soaked in vodka or sputum.
or, immediately proceed to the next step -

- Arrange a warm shower for citrus. Cover the pot with a plastic bag to keep water out and rinse the lemon out of the shower. Using a foam sponge and laundry soap, wash the entire lemon crown: leaves, stems and branches. Let the plant dry.
- Application of acaricide. Depending on the type and instructions, the drug is diluted in water and the plant is sprayed in the morning or evening. The solution must be applied immediately.

For best effect, you should put a plastic bag on the citrus crown. This is how we ensure high humidity, an environment that can not stand spider mite. The package can be removed after 10-24 hours.

Treatment with acaricide should be repeated after 5-6 days, 3-5 times!

Some citrus growers argue that in order for the fight against ticks to be more effective, the dose of the drug should be increased. I will write only those about which I learned that the dose was increased. With other preparations, care must be taken not to burn the citrus leaves.

* 5 ml per 1.5 l of water,

** 8-10 ml per 1 liter of water, you can add to the solution green soap(or soap solution, shampoo)

*** Tbutter -1 cap of milk, the same amount liquid soap+ 1 liter of boiling water, shake. Spray outside.

Gardeners also practice the use of a solution of acaricide + potassium + calcium. That. the cell walls of the plant are strengthened and it is harder for the mite to eat it.

Don't forget to take precautions. Wear a mask and gloves.
May your citrus be healthy!

Lemon trees, like others houseplants, can be affected by viral and infectious diseases and pests.

Although this does not happen often, it is better to find out what lemon diseases exist, how they affect external state plants and how to treat them. We will find out what viruses and infectious diseases infect indoor lemon, what pests it can be attacked, and what to do in such cases.

Why is lemon sick

Lemon is easily exposed to diseases and attacks by pests and viruses in the following cases:

If he did not have time to get stronger after recovering from other diseases.
If he is provided with poor care: contaminated soil, poor lighting, illiterate pruning, insufficient soil fertilization, improper watering etc.
If a virus or pathogenic bacteria brought insects or a diseased stalk when grafted.

Viruses and bacteria can get on the plant when the room is ventilated, but this happens quite rarely.

Most often, viruses, bacteria and pests infect indoor lemon leaves. However, if a lemon sheds fruits and leaves, the reason for this may be a lack of trace elements:

If there is a pronounced network of green veins on light leaves, the lemon needs manganese, zinc or iron. Another reason is soil pH disturbances.
If an adult leaf loses its gloss, dries at the ends and turns a reddish-brown color, the plant is deficient in phosphorus.

If pale yellow speckles appear on the leaf, and it turns yellow and fades over time, this indicates a lack of nitrogen.
If notches appear between the veins of the leaves, the lemon needs potassium top dressing.
If the plant drops the ovaries, it urgently needs manganese.

Not useful to the plant and too frequent feeding. If leaves fall on a lemon, what to do in this case? Postpone feeding and evaluate the correctness of care: suddenly you are doing something wrong.

Viral diseases of indoor lemon

We learn about three viral diseases in which a lemon sheds leaves: why they often lead to the death of a plant, and whether they can be cured:

Leaf mosaic

Having become ill with it, the leaves become covered with dark or light strokes in the form of a mosaic, lose their shape. The growth of the tree is noticeably slowed down.

This disease is not treated by any means, but symptoms can be reduced by regularly fertilizing the soil and providing the plant with proper care. If you have other lemons, it is better to destroy the plant affected by the virus as soon as possible.

Cancer of citrus

When affected by this virus, foliage and fruits appear brown spots. When the form is started, the leaf falls off, the lemons take on an ugly shape, and a little later the tree dies.

It is impossible to cure citrus cancer: to prevent it in the spring, we treat the plant with liquid copper fungicide.

Tristeza

Having picked up the tristeza, the lemon loses its foliage, the bark or twigs die on it. The plant dies - it cannot be cured.

Most often, viruses infect weakened lemons that are poorly cared for.

Fungal and infectious diseases of indoor lemon

Consider the main diseases of lemons that are fungal and infectious in nature, their symptoms and methods of treatment.

Most often, indoor lemons are affected by the following fungi and infections:

Gomoz

With homosis, the branches and trunk of the plant are covered with elongated spots of a red-brown hue, under which the bark quickly dies and cracks. Cracks ooze a sticky golden substance that quickly hardens.

Causes of homosis: excessive humidity in the room, cuts or breaks in the bark, deficiency of phosphorus and potassium, excess nitrogen fertilizers, diseased soil or severe deepening of the trunk.

How to treat homosis? We cut off all the stains from the bark of the trunk, treat the sections with a three percent solution and use putty from garden pitch. We repeat the treatment until spots on the bark of the trunk cease to form. If the branches are covered with spots, cut them off entirely and destroy them.

Anthracnose

This is fungal disease, in which leaves fall from a lemon, and what to do about it, many do not know. First, the leaf turns yellow, then flies around, as well as the buds. The branches of the plant gradually die off, and red spots appear on the lemons.

To get rid of the fungus, we destroy the dead branches and spray the lemon with Fitosporin or a one percent solution. Bordeaux liquid. We spray three times.

Scab

Another fungal disease room lemons- scab, in which young leaves are covered with transparent yellowish spots, gradually turning into pink-gray growths. Spreading over the leaf, these growths destroy it along with the shoots. Fruits with scab are covered with orange spots, eventually becoming red-brown. In this case, the lemon discards the fruits.

In order not to destroy the entire plant, we cut and destroy all the affected parts of the plant, and spray the crown with one percent Bordeaux liquid.

Melseco

With melseco, the shoots of the lemon dry up, the foliage falls off, starting from the tips of the branches, and the cut of the branch turns red.

Poor lighting is to blame for this lemon disease: in winter, the plant did not have enough light, and it was not illuminated.

Melseko treatment does not exist: we observe the plant, and if it continues to hurt, we destroy it.

root rot

If a lemon abruptly sheds a leaf, dig it up and inspect the roots. Having found rotten roots, we cut them off and transplant the lemon into a new disinfected soil.

We put the transplanted plant on a bright windowsill, and avoid watering for a week - we just wipe the leaves with damp gauze or a sponge.

In addition to infectious and viral diseases indoor lemons are amazed harmful insects. We will find out which pests attack a home-grown lemon and how to deal with them.

Shchitovka

Scale insect larvae settle on the underside of the leaves and subsequently move to outside. The plant withers, dries, quickly picks up viruses and infections.

To get rid of scale insects, we use a special insecticide or soapy solution, for which we dilute 2 tbsp in water (1 l). any liquid soap. we wet soapy water all places affected by insects. We wait one hour, wash the plant in the shower and after a couple of days repeat the treatment.

Aphid ordinary

Colonies of light green aphids usually settle on young shoots that are not overgrown with bark. First, they attack the bottom of the leaf, then move up, sucking out the juices along the way. The leaves curl up and die.

If there are few aphids, we cut off the affected shoots and destroy them together with insects, after which we feed the plant complex fertilizer. If the aphids have covered most of the indoor lemon, spray the tree with an insecticide or garlic infusion, for which we clean 4 heads of garlic and soak them in 5 liters for 24 hours. After we filter.

spider mite

Young twigs and leaves are often affected by this insect. The foliage curls up and a web appears around it. The appearance of spider mites is to blame for the lack of humidity.

To get rid of insects, spray the tree with a one percent solution. boric acid by repeating the procedure four times.

root aphid

Unlike the common aphid, the root aphid found in contaminated soil infects the roots.

To exterminate it, we transplant the lemon into disinfected soil, treating the roots with a contact insecticide or a weak garlic tincture.

In many sources, you can find advice on treating lemon with an alcohol solution - this is strictly prohibited. Lemon does not tolerate alcohol.

As you can see, lemon diseases are numerous and sometimes very serious: some lead to the death of the plant. To protect it from adversity, plant the plant only in disinfected soil, give it a regular shower and wipe the foliage and branches with wet gauze, treat the crown with soapy water once a month, and inspect the tree more often for disease or insect infestation.

Indoor lemons are not exotic for a long time. Very unpretentious in care, they delight not only with year-round greenery, but also from time to time with real fruits.

A spider mite on a lemon does not reveal itself immediately. Tiny, no more than a millimeter in length, the insect gives itself away, leaving traces of vital activity - a thin cobweb on the foliage and trunks of plants. The most favorite habitats are the underside of the leaves. The pest itself is red, and its larvae are green.

Both of them bring significant harm to indoor lemons - they feed on the juice of the plant. As a result, citrus experiences a lack of fluid and minerals, the foliage begins to turn yellow and fall off. Considering how quickly the pest multiplies, you can lose not only your favorite lemon, but also other indoor plants: the tick infects neighboring flowers quite quickly.

How to get rid of spider mites

As soon as a spider mite is found on a lemon, control measures should be taken immediately.

Chemicals

There are a lot of insecticidal preparations against domestic pests of citrus. In any department for flower growers, they can offer a huge amount.

Which one to give preference to?

The following "chemicals" are the most popular:

Demitan. Means with phenazakhine as an active substance of contact action, preserving protective properties up to 2 months. Demitan is inhalation toxic. That is why the treatment is carried out with precautions and using means personal protection(respirator and gloves). Toxic to fish, slightly toxic to warm-blooded animals;
. The solution for spraying is prepared in proportions: for each liter of water - a milliliter of the drug. Actellik kills not only ticks, but aphids;
. A low-toxic agent, effective not only against ticks, but also against a number of other domestic pests on flowers. Processing is carried out several times at intervals of 3-4 days.

Folk methods

Chemical preparations allow you to quickly defeat pests on lemons. But if the tree is fruitful, if there are fruits on it, such processing can be dangerous. If a spider mite appeared on a lemon, how to deal with folk remedies?

When a spider mite appears on a lemon, how to get rid of it without treatment? Insect does not like high humidity, and if you move the plant to a cooler and less dry place, regularly water and spray with water, the pest will disappear by itself.

Conclusion

Very often a spider mite appears on a room lemon, not all flower growers know how to deal with it. But the belief that the fight against this pest is incredibly difficult is erroneous. It is quite possible to get rid of a tick, the main thing is to choose the right method.

Caring for indoor plants requires considerable strength and patience, because they, like garden plants, are susceptible to attack by pests and all kinds of diseases. To get rid of insects quickly and reliably, you need to know which drugs to use in each individual case.

A homemade lemon can become a victim of any insects, however, such pests most often attack it:

scale insects are sedentary pests that stick to the leaves of the plant with the help of wax produced. Over time, the entire surface of the lemon will become sticky, after which the leaves turn yellow and actively fall out;
spider mites - the onset of infection of a plant can be determined by the appearance of brownish spots on the sheets. Over time, the leaves become covered with cobwebs, along which small red dots move - this is the spider mite;
aphids - yellow-green insects are not very visible on the surface of the trunk, so it is rather difficult to notice them at an early stage of appearance. Very quickly, their numbers increase, occupying not only the trunk, but also the leaves on the lemon.

For each individual case, certain preparations should be used, since some insects are immune to chemically active components. Ideally, you need to prevent the appearance of insects and regularly monitor the hygiene of the plant.

Lemon aphid, actively breeding, is clearly visible on the young shoots of the tree, numerous insects are located along the entire surface of the stem. Adult insects can be from 1 to 3 mm in size and have a yellow-green color, while the larvae are almost transparent and much smaller.

Aphids enter the apartment through open windows and doors, and can also go to the lemon from flower bouquet, so you should not put flowers and other indoor plants near the lemon tree.

If a tree grows under the window or a flower garden is located (which is often typical for the lower floors), then you should not put a lemon near the windowsill. Pests quickly move into the apartment through an open window, and some small insects able to penetrate inside through minimal cracks and holes.

Citrus trees are the most susceptible to pest attack, as their attractive sweet aroma attracts all insects like a magnet. Since the attacks of uninvited guests cannot be avoided, the easiest way is to prevent their occurrence.

Firstly, regularly (3-4 times a month) you should arrange refreshing procedures for the tree and wash its leaves and branches on both sides under warm shower. During bathing, the soil should be isolated by covering it with a plastic bag.
Secondly, when acquiring new indoor plants, at first they should be isolated from the lemon, since the pests present there can very quickly attack the citrus tree.
Thirdly, it is advisable to arrange a daily routine inspection of the lemon, since, having noticed the appearance of insects at an early stage, it will be much easier to get rid of them.

If aphids have already attacked your tree, you can get rid of pests in the following ways:

with a slight spread of pests, a solution of green or ordinary laundry soap, which should wash all the leaves and stem of the tree. After 4-5 days, the procedure should be repeated, usually two times is enough to get rid of aphids for a long time;
in the fight against aphids, tincture of herbal preparations will help. You can use a decoction of nettle or wormwood - 2 tablespoons of dry collection are infused in a glass of boiling water for 12 hours, after which they are filtered and the damaged leaves are treated with the resulting solution. The elixir of propolis has a destructive effect against aphids, the easiest way is to take a pharmacy solution and dilute it with boiled water in a ratio of 5:20 (tablespoons are taken into account, this amount is enough to process a small tree);
a solution of tobacco dust infused with boiling water with the addition of laundry soap shavings helps eliminate existing pests and prevent the emergence of new ones. The plant is sprayed with this composition every other day for a week, after which the procedure is repeated after 5-7 days;
garlic water is also effective in controlling the spread of aphids. The head of garlic should be rubbed through a meat grinder or grater, put the gruel in a glass hot water and insist in a dark place for 48 hours. Spray according to the previous scheme;
the simplest and effective method get rid of aphids on a lemon tree - treat the plant with dichlorvos. To do this, the tree is placed in a hermetically sealed plastic bag, where a cotton swab moistened with dichlorvos is first placed. The plant is left in this position for 4-5 hours, after which the leaves should be washed with clean warm water. If necessary, the procedure can be repeated after a week.

If homemade recipes do not help in pest control, you should resort to insecticides that are sold in hardware stores, or call professional gardeners for help.

Growing citrus fruits at home is not an easy task. Unfortunately, lemon Tree, like other types of citrus grown in pots on windowsills, is susceptible to various diseases.
