Someone is eating sorrel leaves. Treating sorrel against pests

Sorrel is an incredibly healthy, tasty and absolutely unpretentious plant to care for. But sadly, it is highly susceptible to various diseases and “loved” by many pests. To grow a healthy, juicy crop and in sufficient quantity, you need to have an idea of the main diseases and pests of sorrel, as well as measures to combat them (photo examples are attached for your reference).

Sorrel pests and methods of controlling them

It would seem that such an acidic plant as sorrel should not particularly attract pests. However, with the beginning of summer, pests can invade your garden plot, and in quite a large number and variety. In principle, if you follow the agricultural practices of growing the crop (remove weeds in a timely manner, harvest more often, do not grow sorrel in one place for more than 3 years, etc.), you can minimize the likelihood of various insects appearing in sorrel beds.

Advice. Many gardeners prefer chemical pest control products. If you are also a supporter of such treatments, make sure that the chemicals are added to the soil no later than a month before the first juicy sorrel sprouts appear.

Let's look at the most frequent “guests” in sorrel beds.

Aphid. With its appearance, this pest can create a great threat to the sorrel plant, since it completely affects it. Initially, aphids appear on bushes and leaves of trees, and when they are no longer juicy and young, they spread to garden crops, including sorrel. It is very easy to detect aphids; you just need to turn the sorrel leaves upside down. The pest reproduces very quickly, feeding on the juices of the leaves. The result: yellowing, wilting, weakening of roots and death of the plant.

Infusions prepared from burdock, tomato tops, and garlic are considered an effective method of pest control. An infusion of ash mixed with laundry soap is also considered a good remedy.

Attention. It is known that aphids often become the “culprit” for the appearance of another dangerous pest - the spider mite (it forms a web on inflorescences and leaves). You can avoid such a nuisance by expelling ants from the area, which usually protect aphids, and placing ladybugs/lacewings in the garden plot.

Leaf beetle. A sure sign of the presence of a pest is considered to be sorrel leaves “riddled” with holes. This happens in the spring. In addition to the fact that the beetle eats leaves, it also creates 2-3 egg clutches on their reverse side, which manage to turn into adult beetles over the course of a season. The method of pest control is very simple: the pyrethrum plant. It can be planted directly on the site, or you can treat the sorrel with a tincture of this flower (2-3 sprays per season are enough).

Sorrel sawfly. This two-winged pest also actively raises its young in sorrel beds throughout the harvest season. Moreover, the amount of damage it causes increases with the approach of winter. Small green caterpillars hatching from eggs actively eat sorrel leaves, leaving only “skeletons”. To prevent the appearance of the pest on the site, carefully ensure that there are no weeds in the beds and no remnants of greenery between the rows. You can also spray sorrel leaves with chamomile infusion with the addition of regular laundry soap.

Sorrel sawfly

Fall armyworm. This dark-winged butterfly, with its appearance on the site at the end of spring (approximately by May), causes a lot of harm to plants. It feeds on sorrel leaves and moves to the base closer to autumn. For prevention purposes, you should carefully dig up the soil on the site in the autumn, after harvesting. As an additional measure, you can hang containers with molasses or fermented liquid above the sorrel beds at a height of about 1 m above the ground.

Wireworm. This tiny insect can cause very big problems. It loves to feed on plants (their terrestrial part). If the soil dries out, it goes deeper into the soil and eats the roots. To avoid the appearance of a “guest” you should: regularly remove all weeds from the beds, neutralize acidic soil, dig up the soil after harvesting, and do not grow the crop for too long in one place.

Diseases of sorrel and methods of combating them

In addition to pests, sorrel also “suffers” from various diseases. Among the most dangerous and most frequently encountered are the following:

Rust. A very common disease in temperate climates. A sign of a diseased plant is some kind of yellowish blisters on the leaves. Over time, the bubbles burst and spores spill out. Control measures: it is mandatory to destroy the remains of leaves on the beds and dig up the soil on the site in the autumn. Mulching (in spring) the soil with peat, sawdust, and humus can also give good results.
Gray rot. A sign of the disease are burgundy spots on the leaves, which, in turn, become watery, lethargic, and then rot. Often the appearance of rot is associated with the thickening of sorrel beds, as well as the storage of fresh sorrel. Control measures: to begin with, it is necessary to plant sorrel in an area with sufficient access to air and sunlight. Additionally, you can mulch the soil with peat.

Follow agricultural practices and the risk of crop disease will decrease

Downy mildew. The plant “sick” with it mainly in the first year of life. Leaves affected by the disease become brittle, wrinkled, thicken, and the edges curl downward. It is noted that the disease actively manifests itself in humid, rainy weather. Control measures: timely removal of weeds from the beds, as well as diseased sorrel leaves. It is also necessary to spray the crop with Bordeaux mixture.
Spotting. There is more than one spot that can affect sorrel: septoria, ovularia, etc. It is not so easy to distinguish them from each other. But all varieties of the disease have one thing in common: they spread on the leaves in the form of spots of various shapes and colors. A proven way to combat the disease is to timely remove and destroy diseased leaves from the beds, remove leftover leaves from the area, and mulch the soil with humus in the autumn.

This concludes our material. Be careful when growing crops and do not forget to follow agricultural practices. Good luck!

Seeing that the sorrel in the garden is covered with holes, many novice owners do not know what to do. But for experienced summer residents, this sign indicates that pests liked the crop. It is traditionally believed that the plant protects itself from many of them on its own, without any drugs: insects are repelled by the taste. But there are also “gourmets” who love sour things. By eating leaves, they make them “holey.” I don’t want to share the sorrel harvest with pests, and it is no longer advisable to treat it with chemicals during this period. In this case, folk recipes and advice will come to the rescue.

Leaves in a hole as a result of the work of a leaf beetle

This little bug is the main reason sorrel becomes holey. After overwintering, the pest settles on a leaf, eats it and lays eggs on the reverse side. Over the summer, 2-3 generations of sorrel leaf beetles can develop. It’s easy to make sure that it is the leaf beetle that has settled on the plants: just look at the back of the leaf. The larvae of the pest are spindle-shaped, dirty yellow in color. Grown-up insects look like this:

up to 0.5 cm in length;
in color - greenish or bluish, with a tint.

Attention! Adults leave large holes in the sorrel, while the larvae eat away the pulp between the veins.

Methods to combat the leaf beetle:

wood ash + tobacco dust (ratio 1:1). Duration of procedures – 4-5 days;
pyrethrum (Dalmatian chamomile) powder;
ash (1 tbsp.) + dry mustard + black hot pepper (1 tbsp. each). All this is placed in two layers in a piece of gauze or an old nylon stocking.

Advice. After the entire crop has been harvested, you need to dig up the soil. This is to destroy the beetles that are going to overwinter in the soil. Plant sorrel in the shade, under trees, and next to it sow Persian, Caucasian, Dalmatian chamomile.

If sorrel is eaten by slugs or fall armyworms

The fact that slugs are encroaching on the plant is evidenced not only by holes, but also by a silvery mark on the leaves. These pests are especially active in humid weather. To rid sorrel of voracious slugs, any of the following methods will do:

Sprinkle the row spacing with a narrow strip of lime, superphosphate or ash.
Spray the crop with 10% ammonia.
Set traps. For example, beer trays.
Collect slugs by hand.

Attention! In order not to attract slugs to the site, do not litter the dacha, remove weeds,

The winter cutworm is a grayish-brown butterfly up to 5 cm long. It also eats large holes in the leaves. Autumn digging of the soil and removal of weeds are suitable measures to prevent this pest. For example, the following methods are suitable for insect control:

hang containers with fermenting products or molasses at a distance of 1 m from the ground;
spray the plants with burdock infusion (to prepare it, you need to pour 0.5 buckets of fresh crushed leaves with water and leave for 3 days).

Sorrel plantations are sometimes plagued by other pests. For example, the sawfly eats up greenery, leaving only the veins of the leaf blade intact. Because of aphids, plants turn yellow, wither and die. There are also many means to combat these insects. However, the risk of damage to sorrel will be minimized if the crop is initially provided with good care.

It would seem that sorrel leaves are so sour that not a single pest would be attracted to them. But with the beginning of summer, they can surprise the summer resident with a change in color, holes, and then it is clearly obvious that someone else will harvest the harvest - the leaves are so eaten. Unpretentious bushes that easily survived the winter may stop growing and even dry out in the middle of summer.

Informational video with useful tips on protecting plants from pests.

Leaf beetle

Aphid

If aphids appear on the site, and they first settle on bushes or trees, then this is a direct threat to the leaves and the entire sorrel plant. Aphids eat the leaves of bushes and trees while they are young; as soon as they become coarse (or there are none left at all), the aphid prefers to move to the garden; vegetables become its target, and sorrel is among them. Aphids reproduce very quickly, live on the underside of leaves, and suck the juice from them. The result is yellowing, wilting of the greenery, weakening of the roots, and death of the plant.

Aphids provoke the appearance of another pest - the spider mite, which is indicated by the cobwebs that begin to appear on the inflorescences or young leaves. Prevention can be done by expelling ants from the area, which diligently care for aphids and protect them. It’s good if ladybugs or lacewings settle in the garden - they will be able to protect the vegetables. They fight aphids with infusions or decoctions of green tomatoes, burdock, dandelion, and garlic. You can use an infusion of ash mixed with laundry soap.

Sorrel sawfly

This insect with two pairs of wings also gives rise to several generations over the summer, which actively feed on sorrel greens. The closer autumn is, the greater the damage from it; the caterpillars of the sorrel sawfly eat the entire leaf, leaving only a skeleton of veins. It overwinters as an adult insect under plant debris. You can protect a garden bed from it only if there are no weeds on it and the ground is not covered with plant debris. And a tincture of chamomile will help you fight - make an infusion, add laundry soap to it, and spray the sorrel after a week.

Fall armyworm

A butterfly with brown, very dark, almost black wings appears at the end of May; it brings a lot of trouble to vegetable gardens, as its caterpillar feeds on vegetable leaves. It grows up to 5 cm, leaves large holes on sorrel leaves, and closer to autumn gnaws plants close to the ground. Overwinters in the soil, loves deposits of plant residues. To get rid of it, you need to dig the soil deeply in the fall. She is distracted from the sorrel by placing or hanging vessels with molasses or something fermenting at a height of 1 m above the ground.

Then there is a chance that she simply will not notice it, which means she will not settle her voracious offspring on it. To defeat the winter cutworm that has settled in the garden bed, burdock infusion is perfect. They need to treat the plants 3 – 4 times a week.

Wireworms

If a click beetle, a small creature (up to 1.5 cm), has appeared in the garden bed, then trouble is guaranteed for the sorrel. It overwinters in the soil; at the beginning of summer, females lay eggs almost at the very surface. The larvae, and these are wireworms, develop underground for a long time - 3 - 4 years, feeding on underground parts of plants. The drier the earth becomes, the deeper they burrow into it, feeding on the roots. Pupation occurs at a depth of up to 15 cm.

Wireworms love acidic soils and an abundance of weeds. If you prevent the growth of weeds, especially wheatgrass, deoxidize the soil, dig it thoroughly to a depth of 20 cm, and do not leave the sorrel to grow in one place for many years, then there is a chance to protect it from the larvae of the click beetle. These larvae leave wire-like tunnels in root crops and are very fond of potatoes. Here you can distract the wireworm from the sorrel by spreading the cut potatoes between the plants on the surface.

Slugs can also damage sorrel greens if the garden bed is too wet. They are fought with the help of tincture of hot pepper. The roots of sorrel are often undermined by mole crickets if they have already appeared on the site. But it doesn’t mean at all that your sorrel will be attacked by all diseases and pests at the same time. With proper care, it usually grows well and delights its owners with vitamin leaves.

How to treat sorrel against diseases and pests: caring for greenery

Cold and damp soil, what else is needed for the fungi that overwinter in the soil to become active. All these factors lead to all sorts of diseases and damage to the sorrel, which must be combated by treating the beds and removing pests mechanically. It should be noted that sorrel bushes suffer not only in the spring. Often in the middle of summer, healthy green leaves turn yellow, dry out or become spotted. There are many ways to restore plants to a healthy appearance: insecticides, folk recipes, traps; for each pest you should choose the most effective remedy.

Video "Growing"

From the video you will learn how to effectively grow sorrel.

Aphid

Microscopic insects, 2-3 mm long, black in color, settle in colonies on the stems and undersides of leaves. They reproduce very actively - up to 15 generations per season. Aphids feed on the sap of the above-ground part of the plant, as a result of which the leaf blades wrinkle, and then turn yellow and dry out.

Aphids attract other pests to sorrel - spider mites and ants, so you need to seriously fight them. Prevention consists of thoroughly cultivating the soil and destroying weeds (aphid larvae overwinter on weeds and in the ground). You can fight aphids with folk remedies: decoctions of burdock, tobacco, garlic, onion peels, infusion of ash with laundry soap. The bed can be sprinkled with dry ash or tobacco dust.

Sorrel sawfly

The main control measure is the removal of weeds during the season, the complete destruction of plant residues in late summer and early spring. To combat the pest, a decoction of chamomile with the addition of laundry soap is used. Spraying with infusion is carried out at intervals of 7-10 days.

Leaf beetle

Since the beetle loves moisture, instead of spraying it is recommended to sprinkle the plants with tobacco dust mixed with ash 1:1 for 4-5 days until the pest disappears. It is necessary to regularly get rid of weeds. The beetle does not like manure; you can periodically water the garden bed with a liquid infusion.

Fall armyworm

A small (2-3 cm) butterfly with gray-black wings lays larvae at the end of May, from which caterpillars of the same color emerge. The insect itself is harmless, but over the course of a season it can produce 2-3 generations of very voracious caterpillars that feed on juices and gnaw large holes in leaf blades.

To get rid of caterpillars, sorrel leaves can be treated with burdock infusion 3-4 times during the week. You can distract the pest by placing jars of bait - a sweet, fermenting liquid (honey, malt).

Wireworms

The thin yellow-brown caterpillars are the larvae of the click beetle. This is a small (up to 15 mm) insect with a red body and a black head. The beetle overwinters in the soil, where it lays its larvae.

Wireworms live a long time (3-4 years), burrowing deep into the soil and feeding on the underground part of plants - roots, and damage to the roots leads to the death of the entire plant. You can protect your beds from the pest by regularly removing weeds, liming the area (wireworms love acidic soil) and annually replanting the sorrel to another place.

Medvedka

This is the most malicious pest of all garden crops. Lives in the soil, making deep tunnels and damaging plant roots. The mole cricket is capable of swimming and flying, so it is difficult to fight it. If the bush dries out and is easily pulled out of the soil, this is a sign of mole cricket damage. The pest has a complex and long period of reproduction, as well as the development of larvae.

As a rule, gardeners fight mole crickets with mechanical destruction and folk methods: they plant fresh garlic and eggshells in the ground, water the area with infusion of onion peels, chicken droppings (2 kg/10 l of water), and kerosene diluted with water.

Piles of manure are used as bait - insects crawl there, after which they are easier to destroy. A radical way to combat mole crickets is the insecticide in granules “Anti Medvedka”.

Naked slugs

These pests live in excessively moist soil and may appear in early spring or during the rainy season. They live in the ground, crawling to the surface only at night to eat leaves. After a meal they leave silvery marks on the plants. They breed in a damp place, under a pile of plant waste. Traditional methods of control: treating the bed with tincture of hot pepper or 10% ammonia solution, scattering lime and ash between the rows. Slugs crawl into traps containing fermenting liquids and beer.

Rust

Brown-yellow spots on leaf blades and petioles are a sign of fungal development. Multiple spots with a swollen yellowish surface on which fungal spores are located lead to drying out and death of sorrel. For treatment, a solution of potassium permanganate (5 g/10 l of water), a solution of copper sulfate with laundry soap (1 g of vitriol, 20 g of soap/1 l of water) is used. Rust preparations: Plangiz, Fitosporin.

Mildew

Another fungal disease that affects green vegetable crops. It appears as a grayish coating in the form of spots on the leaf blades. The leaves wrinkle, curl, and the coating becomes darker in color.

Among the folk recipes against downy mildew, solutions are used: mustard powder (2 tablespoons/10 liters of water), rotted manure (1 part manure/3 parts water, leave for 3 days), spraying is carried out 2 times a day. Chemicals: Vitaros, Previkur.

How to spray sorrel against pests

Sorrel is one of the favorite crops of all gardeners. Its green leaves appear almost the very first in the garden.

And we, having yearned for any herb during the winter months, take great pleasure in collecting this first harvest to prepare our favorite dishes. But, as it turns out, not only garden owners adore sorrel; uninvited parasites also love to feast on it. We call them garden pests, and sorrel, unfortunately, has quite a lot of them.

Pests of sorrel

The beetle is a leaf beetle. This is a small insect, similar in color to a firefly. You won't notice them right away. But if holes appear on the leaves of sorrel, then it is highly likely that the plants are being attacked by leaf beetles.

In order to decide what can be used to spray sorrel against pests, you need to find out who attacked it. No matter how carefully this plant is cared for, it is likely to be attacked by pests.

Pests and diseases of sorrel

Like any other plant, sorrel has pests. They mainly attack young and succulent leaves, but can attack the roots.

Leaf beetle. Eats through holes in sorrel leaves. Eggs are laid on the leaves on the underside. Over the course of the summer, more than two generations of the pest can develop.
Sorrel sawfly. It eats all the pulp from the leaf, leaving only the veins. The greatest damage to the crop occurs closer to autumn.
Aphid. It multiplies quickly. Up to 15 generations can develop over the summer. Lives on the underside of the leaf. It sucks the juice out of the plant, after which the leaf curls, turns yellow and dies.
Winter armyworm. A butterfly with almost black wings that attacks in late spring. It chews large holes in the leaves.
Naked slugs. They leave behind silvery traces. The leaves are eaten away at night when there is high humidity.
Wireworms. Click beetle larvae. They feed on underground parts of the plant. If the top layer of soil dries out, they go deeper into the ground.
Medvedka. Lives in the soil, very rarely crawls to the surface. Can fly and swim. The underground part of sorrel is damaged. The plant dries out and is easily pulled out of the soil.
Mildew. Appears in the form of blurred spots with a grayish tint on the bottom of the leaves.
Rust. It is characterized by brown-yellow spots appearing on the leaves of the plant. Dark brown spores form on top of the spots.

Spraying sorrel against pests

When fighting pests that attack sorrel, you can use both solutions with a chemical base and without chemicals. When spraying poison on a plant, it is important to remember that in most cases it is impossible to do this immediately before collecting leaves. All procedures aimed at destroying pests and fighting diseases are recommended to be carried out in the autumn, when the crops are no longer harvested.

Use of chemicals when spraying sorrel against pests:

hexachlorane dust is used against sorrel sawfly;
a solution of anabasine sulfate with added soap is diluted in water at the rate of 15 grams of the drug and 40 grams of soap per 10 liters of water. Used when sorrel is damaged by aphids;
a solution of washing powder or chemicals such as “Phenoxina PLUS” have a detrimental effect on the mole cricket;
Bordeaux mixture is sprayed onto sorrel 10 days before harvesting leaves when affected by downy mildew.

You can spray sorrel against pests with solutions prepared from natural ingredients:

infusions and decoctions of burdock, dandelion and tomato help defeat aphids;
spraying sorrel with a solution of pyrethrum powder will protect against attack by the leaf beetle;
against slugs use a tincture of hot pepper. Take 0.5 kg of crushed pepper for 5 liters of water and leave for 2 days. 200 g of concentrate per bucket of water is enough;
Greater burdock is used against the fall armyworm. Fill 1/3 of the bucket with freshly cut leaves and add water. Leave for 72 hours. Strain and apply 3-4 times a week;
Chamomile will help in the fight against sorrel sawfly. 1 kilogram of dry or 3 kg of fresh chamomile is poured into a ten-liter bucket and filled with hot water. After 12 hours, dilute with water - 1:3 and add soap at the rate of 40 grams for every 10 liters.

Leaves in a hole as a result of the work of a leaf beetle

up to 0.5 cm in length;
in color - greenish or bluish, with a tint.

Attention! Adults leave large holes in the sorrel, while the larvae eat away the pulp between the veins.

Methods to combat the leaf beetle:

wood ash + tobacco dust (ratio 1:1). Duration of procedures – 4-5 days;
pyrethrum (Dalmatian chamomile) powder;
ash (1 tbsp.) + dry mustard + black hot pepper (1 tbsp. each). All this is placed in two layers in a piece of gauze or an old nylon stocking.

The oxal aphid is ubiquitous. The small insect establishes colonies of several thousand individuals. Over the entire warm season it produces up to 20 generations. It feeds on plant juices, causing leaf deformation and loss of crop vitality. How to deal with aphids on sorrel is one of the most common questions among gardeners and gardeners.

Who do you have to deal with?

To defeat the enemy, you need to collect more information about him. The oxaline aphid is a small insect with a body length of no more than 2.5 mm. From spring to early August, the young female generation is born. Fertilization is not required to prolong the race.

The oxal aphid prefers to lay eggs on weeds from the buckwheat family. In the spring, larvae emerge from them and develop at a rapid pace. After just 2 weeks, a new generation of aphids appears.

On a note!
You can notice the presence of aphids on sorrel by the appearance of the plant. The leaves become coarse, turn yellow, and spots appear. Upon careful examination, black dots are visible on the stems and on the back of the leaves - these are aphids. If you leave everything as is, the pest colony will grow rapidly. The plant weakens, gets sick, dies.

Fighting methods

You can also get rid of aphids on sorrel using professional preparations. When choosing a method, you should take into account the period of infection and the number of insects. Safety should always come first.

Insecticidal preparations with a validity period of up to 20 days should not be used. The poison must be completely dissolved before harvesting. In the case of sorrel, this is problematic. Since the crop is harvested every 1-2 weeks.

Traditional methods

How to treat sorrel against aphids is the question everyone asks when they see a large colony of pests on the crop. It is not at all necessary to run to the store for an effective drug; you can prepare it yourself. The amount of solution required is calculated based on the size of the bed with sorrel. Recipes are based on 1 liter of water:

Dissolve 1 tbsp in cool water. spoon, salt, add laundry soap so that the product becomes viscous. Treat the plant with a spray bottle, paying special attention to the stems and lower parts of the leaves. Repeat the procedure after 3 days.
You can fight oxal aphids. The arrows are scattered on the beds, and a solution is prepared from the cloves. Chop the garlic to make 1 cup. Add water. Leave to infuse for a day. Add . The plant should be treated early in the morning or late in the evening. The procedure is repeated after 3-5 days.
Dilute woody water in cool water. Concentration does not play a special role. Add soap base. Spray the plant with the solution. Sprinkle dry ash between rows. One procedure is enough to destroy pests. Instead of ash, you can use tobacco dust.

Fighting aphids on sorrel with folk remedies is allowed during any growing season. Before using greens for food, it is enough to wash the leaves well under running water.

The most effective drugs for aphids on sorrel are Strela and Fitoverm. To prepare the solution, the concentrate must be dissolved in cool water. This must be done immediately before processing the crop.

It is necessary to think about protecting sorrel from aphids in advance, without waiting for the active action of the aphids. You should remove weeds in a timely manner, dig up the soil twice a season, spray the plant with biological products or solutions according to traditional recipes once every 14 days for prevention.
