Chlorosis of plants. Signs and treatments
Content:
Plant chlorosis is a disease in which less chlorophyll is excreted. Which, naturally, disrupts the work of photosynthesis.
Plant chlorosis and its causes
There can be more than one cause of chlorosis in plants. Chlorosis has three types: infectious; functional; non-infectious. And also plant chlorosis can occur due to mutation. Or it can be inherited from the parent instance.
Infectious plant chlorosis
Its appearance is provoked by various fungi, viruses and microorganisms. And also it is very often carried by insect pests.
Functional or non-infectious chlorosis
Functional or non-infectious chlorosis may appear due to improper agricultural practices. And also because of unfavorable weather conditions or affected soil. If the soil is deficient in elements such as: iron; magnesium; zinc; sulfur; lime; nitrogen; protein. Or the soil will be overly acidified, then the root system simply will not be able to absorb the components it needs.
And also non-drained soil can provoke this type of disease. Because of which, the root system will be permanently in a humid environment. Chlorosis is provoked by any mechanical damage to the root system, cramped conditions. As well as close proximity to other crops and the influence of sulfur dioxide.
Signs of chlorosis
- The leaf plate turns yellow. But the veins remain a bright green hue.
- The new leaves differ significantly in size from the old ones. They are smaller.
- The edges of the leaves begin to curl up.
- Foliage, buds, inflorescences begin to fall off.
- The apical places on the branches dry up.
- The buds and inflorescences are deformed.
- Deformation of the root system. And also its decay.
Plant chlorosis: how to treat
When a non-infectious or functional disease appears, all the necessary elements for plant nutrition must be added. And you can also use foliar dressing. That is, to spray the plants. Or enter stamps.
It should be remembered that nitrate nitrogen will provoke the entry of potassium components into the culture. And ammonia nitrogen will reduce it.
If the culture lacks micronutrients
In case of iron deficiency, the following preparations will help: "Ferovit"; Ferrilene; "Micro-fe"; Iron chelate.
If the culture lacks magnesium, with such a problem can help: dolomite flour; magnesium sulfate; mage-bor.
If the culture has sulfuric chlorosis, with this development of events can help: potassium magnesium; azophoska with sulfur. As well as potassium sulfate; diammophoska with gray.And also these funds contain nitrogenous, phosphorite, magnesium, sodium elements. If the plant blooms, then it is better to refrain from introducing nitrogenous elements.
If the plant lacks zinc, it can be corrected with zinc sulfate; zinc oxide; superphosphate with zinc.
If the culture has calcium chlorosis, for this option you can use: crushed eggshell; wood ash. And also slaked lime.
Infectious plant chlorosis
This disease does not respond to treatment. That is, if a plant is affected by this disease, it just needs to be destroyed. Because the infection can spread to the crops in the neighborhood.
Preventive measures
For the purpose of prevention, it is necessary to introduce fertilizers on a mineral basis or organic. If you are unable to figure out the lack of a specific element, then you can use the generic tools.
They usually contain everything you need. This is Kemira Luxe; florist micro; uniflor micro and others. To prevent the culture from getting sick with viral chlorosis, it is necessary to disinfect garden tools. And also the soil itself.
Garden tools must be disinfected before and after using them. This can be done with boiling water. And also with alcohol. Before planting, the soil and seed can be disinfected with fungicidal preparations. And you also need to constantly deal with insect pests.
Chlorosis of plants in tomatoes
Tomatoes do not develop well or grow too slowly. Their leaf plates both turn yellow and curl. And also die off. It can be assumed that they simply lack watering. Unfortunately, it could be chlorosis.
When treating chlorosis in tomatoes, it is very important to find out the deficiency of a certain component. And bring it in. But if it is viral chlorosis, then the bush must be removed. And then burn it. And the place where he grew up should be disinfected with a fungicidal solution. Or potassium permanganate.
If the bush does not have enough nitrogen, then its growth will slow down, the twigs will turn black. The foliage will lose its color, turn yellow. The harvest will ripen faster. But it will be smaller.
If tomatoes lack phosphorite elements, the growth and development of the bush will slow down. The shoots are depleted, the leaf plates will be smaller. And also with a bluish tint and wavy edges. Then the foliage will completely fall off.
What else can tomatoes lack?
If tomatoes lack potash, then old leaf blades will have a black rim at the edges. They curl up and then just fall off. Ripe tomatoes will have dark streaks inside.
This will initially show up on the topmost foliage. It will turn yellow. The growing leaves will begin to bend. And the fruits will start to rot.
If the tomatoes lack copper, the old foliage will begin to lose their color. Young foliage will grow very small. Shoots will become lethargic. And the formed inflorescences will simply fall off.
If the tomatoes lack boron, the bush will form a large number of shoots. That is, it will be very thick. And there will be dry rot on the fruits.
If tomatoes lack magnetic elements, yellow spots will appear on the foliage. As a result, they will darken. The foliage will dry up and fall off. And also the stalks will dry out. The harvest will be small. But ripening quickly.
Chlorosis of plants in cucumber bushes
In cucumber crops, chlorosis manifests itself in that the veins and edges of the leaves begin to turn yellow. But this will not always mean that there is a lack of iron components in the soil of the plant. Finding out the exact reason is difficult. It is even more difficult to cure the plant. Because it will take a lot of effort. As well as time and patience.
How to prevent chlorosis in cucumbers
10-15 days before sowing, organic humus must be added to the soil. It will contain all the elements that cucumbers need. And also it will make all the available components more digestible.
And he, unlike mineral fertilizers, will not be able to apply time to the bush. Organic compost or humus must be added to the hole with a layer of 5-7 centimeters. Then pour over. And after a few days, start planting.
Chlorosis of plants in berry crops
Grape chlorosis or pale sickness. With the development of this disease, the plant disrupts the work of photosynthesis. Growth and development is inhibited. And also the formation of fruits is disrupted.
Non-infectious chlorotic disease can be triggered by an alkaline soil reaction. It is because of her that the root system will not be able to assimilate the iron components.
Also, a grape bush can be ill with such types of chlorosis as: carbonate chlorosis; zinc chlorosis disease; magnesium chlorosis disease. And also copper chlorosis disease; sulfuric chlorosis disease; manganese chlorosis disease.
An excess of hydrogen sulfide in the soil provokes the revival of the disease. It can often develop in heavy soil as well as in wet weather.
Infectious chlorosis of grapes
Infectious chlorosis of grapes is also called yellow mosaic. It can be caused by insect pests called nematodes. This disease is incurable. But it is quite rare. All symptoms are very pronounced in the spring and summer.
To understand for sure that your bush has non-infectious chlorosis, you need to apply a grid pattern on the leaf using iron chelate. If after 24 hours, it appears on the foliage with a rich greenish tint, then the assumptions are correct.
Signs of chlorosis in grapes
- Specks of various yellow shades appear on the foliage.
- Old foliage loses its bright hue.
- Young foliage becomes lemon yellow. It also stops growing and developing.
- The foliage gradually dries up and dies off.
- Internodes on new branches are formed of a smaller size.
- The berries become small.
- The shrub becomes more sensitive to frost.
How to avoid chlorosis in grapes
If you don't want to waste your time fighting diseases, you can plant varieties that are resistant to various diseases. For example, it can be: muskatel; cabernet; Saint Laurent; elbing. And also Pinot Menier; trollinger; Riesling. Traminer will do; pinot noir; limberger and many others.
It is important to know that the most disease-resistant varieties are the sylvaner grapes. European varieties have higher disease resistance than American varieties.
As a preventive measure for chlorosis, auxiliary crops can be planted. For example, clover; alfalfa; green manure cereals. These crops are excellent for improving soil structure.
How to treat chlorosis of grapes
If it was still not possible to avoid the disease, then iron sulfate can be used as top dressing and spraying. It will help restore the work of photosynthesis. But he will not solve the whole problem.
You need to spray once every 7 days. And also it is necessary to restore soil drainage. To do this, the soil must be dug up between the beds. It is also good to mulch. Calcareous chlorosis of plants can be cured with those products that contain iron in a chelated form.
Ammonium sulfate must be added to the soil itself. And spray the bushes with a solution of sulfuric acid. In the spring, 500 grams of ferrous sulfate should be added to each hole for each bush.
How to feed the grapes?
And also do not forget about dressings, which contain potassium, phosphorus, manganese, zinc. As well as other essential elements for proper nutrition of the plant.
If you find a yellow mosaic on your vine bush, then it must be destroyed immediately. Because this disease is very contagious. Other neighboring crops can also be infected with it. For prevention purposes, it is necessary to process the soil and grape bushes during flowering with iron sulfate.
Raspberry chlorosis
Chlorosis in raspberries can be infectious and physiological. They are caused by a lack of nutrients. And also such a state of the soil in which the root system cannot absorb the elements it needs. For example, this situation can be provoked by watering with ice water.
The signs of chlorosis in raspberries are about the same as in any other crops. Yellowish spots appear on the leaf blades. They grow over time. And cover the entire sheet. And then they move on to the branches of the plant. Infected bushes must be destroyed immediately.
Preventive measures
- The planting material must be healthy. And also resistant to disease.
- It is necessary to regularly loosen and weed the soil between holes and beds.
- It is very important to make suitable fertilizers and fertilizers.
- Any insect pests must be eliminated. Especially those that suck nutritious juices from the foliage. Because they are usually carriers of viral and fungal infections.
- Even before the buds on the bush bloom, the raspberries need to be sprayed with a 3% nitrafen solution. This will greatly help in the fight against aphids.
- Before the flowering period and no less than 45 days before harvest, raspberries can be treated with methylmercaptophos solution. The mixture must be prepared strictly according to the instructions.
How to treat raspberry chlorosis
It is very important to establish the cause and type of chlorosis. If the reason has become excessive importance, you need to adjust the watering regime for raspberries. That is, to make it less frequent and less abundant.
If the reason is soil acidification, you need to add gypsum to the soil. 100-120 grams per square meter. You need to water the raspberries with the water that has been in the sun all day and warmed up.
And also in case of chlorosis, fertilizers must be applied, which include nitrogenous elements. During such a period, it is not recommended to fertilize raspberries with manure. And fertilizing with potassium elements should be applied in the very minimum concentration.
If raspberries get sick with a non-infectious chlorotic disease, you need to add forest litter to the soil. As well as organic humus or compost or peat. Watering should be done with water mixed with bird droppings. In a ratio of 1:10.
Chlorosis of plants in strawberries
The causes of chlorosis in strawberries are quite similar to chlorosis in raspberry bushes.
As a preventive and therapeutic measure, strawberries need to be processed with organic farming. That is, with chelatin or ferovit. For 10-12 liters of water, you need about 12 ml of the drug.
It is necessary to water the plants directly under the root. The foliage itself must be treated with a solution of iron sulfate. Watering and processing should be started as soon as you detect the symptoms of chlorosis.
Chlorosis can often appear due to the fact that the soil has been limed. Or because there is a lot of copper in the soil. Because it is she who is the enemy of iron.
To fully make sure that the cause of the disease is a lack of iron elements, you need to draw a drawing on the foliage of plants using iron chelate. If after 24 hours the drawing gives itself out in a saturated green color, the diagnosis is correct.
Chlorosis Infectious Disease
Chlorosis infectious disease is useless to treat. Because during the time that you spend on treatment, it can spread to neighboring plants. You can recognize it because the leaf plates will turn yellow. And internodes will become very short. And also in case of illness, healthy leaves can form. But this does not mean that the disease has receded. Because she will show herself a little later.
Chlorosis in an apple tree
Chlorosis in apple trees is very similar in symptoms to many fruit crops. Pale or yellowish specks on foliage. While maintaining a bright shade of veins, drying of the edges of the leaves.
Also, the reason may be a lack of iron elements.Or the condition of the soil, in which the root system cannot absorb the necessary elements. The main difficulty is that symptoms can only be identified at an early stage of their development. And with an abundant defeat of culture, it will be very difficult to do this.
The main causes and their treatment
First reason
If the foliage begins to turn yellow precisely from the tops, then this may be due to a lack of iron. With this option, the foliage of the plant should be sprayed in 2-3 approaches with an interval of 10-12 days. The following drugs will help: iron chelate; ferovit; agrecol; brexil.
And the structure of the soil can be improved with ferrous sulfate. 100 grams of ferrous sulfate should be diluted in 10-12 liters of water. If the plant has a very pronounced lack of iron, then you need to inject with iron sulfate. Drill a small hole in the barrel. Pour the desired liquid there. And then seal it up with cement.
The second reason
If the foliage has lost its color, most likely the reason is a lack of nitrogenous elements. Nitrogen fertilizers will help to deal with this problem. And the best solution would be to use organic. For example, you can make a mullein solution. To do this, under each apple bush, you need to add 5 kilograms of rotted cow dung.
Third reason
If young leaves turn yellow, as a rule, the apple tree lacks potassium elements. Then it needs to be fed with potassium sulfate. You need to use it like this. Distribute 25 grams of funds over 1 sq. m of land.
Fourth reason
If the foliage turns yellow profusely, dark dots and edges appear on it - the plant lacks manganese and magnesium. To eliminate this problem, dolomite flour and wood ash can be used.
The foliage of plants must be treated with manganese sulfate at a concentration of 0.05%. And you also need to use magnesium sulfate. 150 grams of the drug should be diluted in 10-12 liters of water.
Fifth reason
If the entire crown of the tree begins to turn yellow, the plant lacks sulfur. And the root system is oxygen. It is possible to compensate for the lack of sulfur by introducing into the soil such things as: gypsum; ammonium sulfate; magnesium. And also potassium; ammofoska; rotted manure; organic humus.
If the root system does not have enough oxygen, it is necessary to loosen the soil in a timely manner. And also to mulch the near-trunk spaces with organic materials.
Viral diseases
Viral chlorosis of plants can often be confused with yellow mosaic. It will appear not only on foliage, but also on the branches of a tree. It manifests itself in the form of yellowish spots. As well as irregular yellow stripes. With such a disease, the growth and development of the culture will slow down. The yield will be halved.
Ring spot manifests itself as small yellowish specks on the leaf blades. Over time, the yellow spots lose their bright yellow color. Thus, creating some kind of ring patterns on the sheet plate. And also on the fruits.
With such a disease, the foliage bends. Growth and development is inhibited. The branches are getting shorter. The trunk of the plant becomes thicker. And also the culture tolerates frost worse.
Chlorosis in peach
Peach trees are always very sensitive to iron deficiency. Therefore, chlorosis occurs very often. Initially, the foliage takes on a yellow-greenish tint. Gradually covers the whole plant. Thus, the foliage begins to fall off. And the tips of the shoots die off.
And also plants that have recovered lose their resistance to frost. That is why the next year the tree may begin to suffer from gum flow. With such a problem, the crust will crack, forming various cracks. And also the resin will start to stand out. The shoots will dry up. And growth will stop altogether.
The ejected resin must be removed from the barrel using a sterile and sharp instrument. Clean the wounds themselves.And then disinfect with a weakly concentrated solution of potassium permanganate. Then rub the wounds with sorrel leaves. And also cover with a mixture of clay and mullein in a 1: 1 ratio.
Chlorosis in ornamental flowering plants
In hydrangea, the disease can occur due to a lack of iron in the soil. If measures are not taken in time, then the plant's metabolism will be disturbed. It will begin to weaken, the foliage will be yellow and discolored. But the veins will remain bright green.
It is very important to take preventive measures. Because they will help the disease not develop. And also the plant will have increased immunity.
If you notice the symptoms of chlorosis on your hydrangea, then you need to immediately process its foliage. If the disease has seriously settled on the plant, root top dressing must be applied. An excellent option would be to water the plant with such a solution: dilute 40 grams of potassium nitrate or ferrous sulfate in 1 liter of water. Water the near-stem circle of the culture 2-3 times.
How to treat plant chlorosis in petunias
It is necessary to prepare a solution of citric acid. The concentration should be as follows: 0.5 teaspoon should be diluted in 1 liter of water. Use this solution to irrigate the culture. If the plant does not get better, then 0.5 teaspoon of ferrous sulfate should be added to the solution.
And also the soil should be watered with such a solution. This should be done until the plant begins to form healthy leaves. To speed up the healing process, you need to remove all the buds. Because the plant will waste its energy in vain.
If you do not have iron sulfate, you can use any dressing that contains iron elements. Many gardeners advise spraying. But this is debatable. Because petunia foliage does not tolerate rainy weather very well.
Viral chlorosis of petunia is incurable. The bush just needs to be destroyed so that there is no contamination of neighboring crops.
Chlorosis in roses
If the foliage of the rose turns yellow, but its veins remain bright green, then this may be the first signs of chlorosis in the rose. If you did not feed the rose last season, then perhaps it is due to a lack of iron.
How to treat chlorosis in roses
You need to start treatment in the spring. Before the growing season. A mullein must be added to the hole in the bush. Or organic humus. And also those elements that the plant lacks. In the future, those roses that have had chlorosis do not need to be fed and fertilized with products with nitrogen components.
And also you need to reduce watering. And apply timely foliar fertilization in a complex format. At the time of treatment, crop pruning should not be carried out.

Agrecol... It is a universal complex mineral fertilizer. Which contains most of the items you need. Suitable for both indoor and garden plants.
Chlorosis of plants: the fight against folk remedies
For this disease, folk remedies have not yet been invented. But experienced gardeners are advised to bury rusty nails under the hole. There is a statement that this will help the plant not to experience a lack of iron elements.
Conclusion
It is very important to recognize the disease in time and start fighting it. Also, you do not need to feel sorry for heavily damaged bushes, you need to get rid of them so that there is no threat to healthy plants. Surround your plants with love and care. And then they will thank you with a bountiful and tasty harvest. And in the case of decorative flowering plants, you will be assured of a riot of colors.
