When growing dill, you can often encounter a variety of diseases and enemies of the plant. It is necessary to constantly monitor the condition of the beds and the crop in order to respond to the problems that have arisen, because dill diseases in the initial stage are much easier to treat than when they enter the advanced phase.
Dill diseases and fight against them
Dill suffers from pests and diseases at any stage of the growing season. The crop, which is often affected by insect pests, is threatened, or with insufficient care, the plant suffers from a lack of nutrients, such dill most often has an immunity unstable to diseases.
Dill diseases: peronosporosis
In the first stage, with this disease of dill, dirty yellow spots are formed on the foliage. The further the disease goes, the more the leaves turn brown and become covered with a grayish bloom. The foliage shrivels and dries up. The disease is characterized by rapid development. Literally in 7-10 days, the entire crop will be spoiled to zero.
Peronosporosis actively develops when the temperature in the greenhouse changes, in the presence of weeds and affected plants. Simple folk remedies cannot cure the disease.
At the initial stage of this disease of dill, you can try to treat infected dill with Planriz, Fitosporin-M, Baikal-M and other drugs. These funds have a biological composition, which means that dill can be eaten without unnecessary restrictions.
Dill crops need to be processed every 2 weeks. But if the disease has completely absorbed the dill, then you will have to use chemicals such as Oxyhom, Ridomil Gold, using the dosages that are indicated in the instructions. During the month, the vegetable should not be consumed, since the chemicals contain a large amount of toxic substances.
This disease of dill is considered one of the most popular among diverse plants. Powdery mildew is characterized by the presence of a whitish coating on the plant surface. At the same time, over time, the plaque thickens and spreads more and more.
The plant becomes weak, the pleasant smell and juiciness are lost, the appearance deteriorates significantly. Sundew is carried by insects that can fly, for example, aphids and others. You can infect a healthy crop through last year's affected plants.
At the initial stage, you can use folk methods... Damaged bushes need to be removed. Then treat the good dill with a decoction of onion husks with mustard powder. It is also considered effective to use a soap solution or, for example, diluted milk whey in a ratio of 1 to 10 parts. For 1 liter you need to add 1 drop of iodine.
If the plant is badly neglected, then you will have to use strong chemicals, which contain copper vitriol, antibiotics, Bordeaux solution. It is necessary to use drugs such as Mikosan, Strobi, Terramycin and others. After using fungicides, dill is eaten after 3 weeks.
Dill diseases: phomosis
With this disease of dill, long brown spots with a darkened border and black dots inside the spots are formed on the plant. Branches that are near groundwater can turn pink, and the root system begins to gradually rot.
Dill disease progresses in excessively moist soil, warm weather conditions. Infected weeds, the density of the planted plants, and a small amount of boric substances are also serious factors.
Phomoz is able to eradicate the entire crop in 2 weeks. The disease progresses from an infected shrub to a healthy one. To save dill, you just need to remove the plants affected by the phomosis and destroy them.
The dill that has remained intact must be treated with Bordeaux solution. For the purpose of prevention, the plant is treated with Fundazol, adding fertilizer and boron.
Dill disease verticillary wilting: photo
Dill disease is characterized by stunted growth, wilting of foliage. Dill degenerates and takes on a brown color. This happens because the fungus, penetrating into the plant, clogs the tissues and releases toxic substances. Greens can no longer absorb minerals from the roots in a normal way.
The disease is caused by manure or compost that contains the infection. Verticillium wilt develops in hot climatic conditions with low moisture in the air. The disease has a latent developmental stage that does not manifest itself for about 3 seasons. Unfortunately, this problem has no cure.
For preventive purposes, the plant can be treated with Phytodoctor, Fitosporin-M and others. When sowing seed, then such agents as Trichodermin, Entobacterin, Glyocladin can be poured into the planting holes.
Dill diseases: cercospora
A fungus that infects the greens of the plant. In the intervals where the fungus lives, dark spots appear, on which plaque develops over time. The affected plant dies soon.
The disease lives on weeds, where the cercosporosis fungi spend the winter. And also on plants that have been infected. To prevent the development of an infectious disease, you need to remove weeds and shrubs. For preventive purposes, healthy dill is treated with Fundazol.
The root system of the plant begins to rot, the fungus primarily affects it. The rhizome becomes weak and loses the ability to function normally, which leads to the death of the plant.
In most cases, infection occurs from infected seeds, if the soil is not disinfected in advance, then most likely the plants will die. The most favorable environment for the appearance of a fungal disease is a waterlogged climate, thickening of the plant and heavy soil.
If the black leg has just begun to appear, then for a start, dill needs to be watered less, and the ridges are watered with manganese solution. The use of onion husks, Baktofit, Fitosporin is considered effective.
Dill diseases: fusarium wilting
A fungus that lives in hot weather and excessively moist soil. If the plant is infected, then it changes its color. At the initial stage, the plant turns yellow, and then begins to darken. Excessive content of toxic substances makes food unsuitable.
Fusarium occupies large areas in a short period of time. If the infection is just noticed, then you need to remove the plant with the root system. Planting material must be treated with Vitaros, Fitolavin or other poisons. If the infection is very high, then it is worth using drugs such as Discor or Oxyhom.
With dill diseases, one of the main points is preventive measures. It will be much more effective if you take all the necessary measures carefully and correctly than then save the harvest with all your might.
It should be borne in mind that the fungus in the last stages is incurable.Dill shrubs will need to be removed and burned, and the ridges will need to be treated with anti-fungal drugs. To increase immunity, you need to use the following means: Radiance and Baikal.
Dill: diseases and pests
Harmful insects do not kill plants mechanically. Most of them carry various diseases. It is best to take preventive measures so that pests do not spoil the crop and do not provoke fungal diseases of dill.
Dill pest Klopp-horsefly: photo
One of the most harmful insects that significantly spoil the crop. The foe of dill absorbs the juice and pulp, as a result, the plant withers, and the flowers die, during this the plant does not form seeds.
The occurrence of a bug is determined by the cobwebs on the foliage. During the spring growing season, the horsefly bug is transported to young shoots. Females leave 2-3 eggs on a leaf. After 7 days, the offspring of the bug becomes viable, and after 3 weeks the individuals are considered adults.
In one season, a bug can produce exactly a couple of batches of generations. To defeat the bug, you need to spray the plant with Aktellik and Fitoverm.
Italian bug (striped bug)

The insect got its name from the interesting shape of the body and color, which has a black and red stripe. In April, harmful insects crawl out of shelters, placing themselves on young dill shoots. Females leave their eggs on plants in early June. The eggs are laid during the whole summer period.
The yield drops significantly, as the bugs drink all the juice from the dill, leading the plant to weakening. To remove pests, you first need to collect them in a bowl of water. One of the main points is the removal of weeds and wild umbrella plants.
The pest has a yellow-green transparent color. The insect consumes sap, tops of leaves and tops of young shoots. Dill receives a small amount of useful elements. The plant withers, smell and taste deteriorate. If a lot of aphids attacked dill, then in the near future it will die.
Aphids are not harmful to humans, but you need to know that pests cannot be washed off the plant. That is, when dill is consumed, aphids are also eaten.
Reproduction of individuals is very fast. But what is important is that the pest can be simply destroyed. Aphids do not have a shell or an upper protective layer. This means that chemicals can quickly defeat her. To win immediately, you need to use the following methods:
- Decoction of potato tops. The green top of the potato should be poured with liquid in a ratio of 1 to 5. Boiling is carried out, and then the infusion should settle for 4 hours.
- Infusion of tomato greens. It is prepared in the same way as the infusion of potato tops.
- Infusion of tobacco. Tobacco foliage should be crushed and dipped in warm water in a ratio of 1 to 10. The infusion should be kept for at least 24 hours. In addition, hot pepper is added to the broth.
- Dandelion infusion. You need to take ¼ kg of rhizomes or 0.5 kg of foliage and grind and fill with lukewarm water. The infusion is left for 3 hours.
Before you spray the plant, filter the broth. Dill can be processed 2 times with an interval of 10 days. Laundry or liquid soap can be added to infusions for greater efficiency.
Thus, due to the presence of soap in the composition, the product will stay on the leaf surface longer. And when dry, the sheet will be covered with a thin film that will protect the surface. Spraying is carried out in the morning or in the evening so that the sun does not shine on the seat. Before using dill, you must first wash it.
Carrot leaf flea
The pests have microscopic dimensions - 2 mm, light lime color. The wings are transparent with membranes, the whiskers are elongated, the eyes are reddish. Females lay eggs once a season.
Pests live on conifers in winter. They begin to act actively in early May. The danger for dill is represented by the young and adult generation of insects. Dill enemies absorb the juice, because of which the stem and foliage lose their shape and dries up in the future.
To defeat the insect, you need not plant wild carrots next to the dill. Plant the plant away from coniferous trees and bushes.
Processing should be carried out with tobacco infusion with a mixture of liquid soap or orange peel. You can physically help the plant to fight the enemy. It is simply covered with a special mesh; lutrasil or spunbond is suitable as a material.

An adult insect looks like a butterfly, which has a reddish-brown front wings. But, since there is a large assortment of varieties of moths, the color may vary. The larvae have a red body with greenish veins.
Under warm climatic conditions, females breed about 3 generations of young offspring. The most dangerous is the young offspring of the moth. Pests destroy flowers, seeds and dill buds.
To defeat the enemy, you need to remove the infected parts of the plant and burn them. It is also important to find the right moment to harvest the seeds. You need to constantly monitor the appearance of your site, since moths can migrate from other plants to a clean and healthy site.

The dill pest has a small size, brownish color and transparent wings. The fly destroys the stems. This leads to the fact that the plant rots and withers. Gardeners advise using a mixture of tobacco dust, charcoal, and slaked lime to combat carrot flies.
The ingredients are mixed in the same ratio and the peri-stem region of the plant is poured, using at least 5 grams per 1 m2. The procedure is done 3 times with an interval of 10 days.
A good result can be obtained using an infusion of tomato tops and laundry soap.
You can also make your own broth from such crops: burdock, onion, garlic, chamomile and others. The aroma of these plants is very tart for a carrot fly. To prepare the product, you need to pour 300 grams of the plant with 2 liters of boiling water and leave for 24 hours. After the solution has reached 10 liters, then it is worth adding liquid and 50 grams of grated laundry soap to it. The method is effective for no more than a week.
They feed on stems and leaves, gaining weight quickly and causing significant damage to the plant. Anise sailboat butterfly is no less dangerous for dill. The young generation of enemies are caterpillars that have a black and yellow striped color. As a result, bluish-colored butterflies are formed in the future.

An unusually beautiful individual that brutally destroys dill. The body is greenish in color with orange-blackish dots, which are located horizontally on the body. Once formed, it begins to actively and rapidly feed on young dill shoots, and adults eat flowers and seed.
You can fight pests with the help of birds and ladybirds. If you do not destroy the latter, then the birds will collect caterpillars and ladybirds. You can also remove annoying enemies with your own hands. You can also make a hot pepper infusion and then spray the plant.
To prepare the material, you need to pour 1 kg of vegetable with 10 liters of liquid and leave for 48 hours. After the infusion, boil for about an hour and leave it to infuse for a couple of days. For maximum safety, the solution can be placed in a tight container and stored in a dark place.
To process the plant, you need to dilute 75 ml of the infusion with 5 liters of liquid and add 40 grams of liquid soap.
Treatment of plants with chemicals is considered a serious issue, since they are harmful not only to the plant, but primarily to humans. If there is already no way out how to apply potent drugs, then you need to use funds for certain pests.
Dill diseases: effective preventive methods
It is important to remember that the use of chemicals should be postponed until the very last resort. Because you can get severe poisoning, since the plants will be completely saturated with all kinds of chemistry. To prevent spoilage of the crop, you need to do prevention.
- A seat is chosen that is well equipped with sunlight and full circulation of air masses. With a small amount of light, the dill begins to stretch. If the amount of sun is excessive, it can cause the plant to burn out.
- Disinfection of seed. To disinfect the seeds, they need to be immersed in a solution of potassium permanganate for half an hour. Use 1 gram of substance per 0.1 liter of liquid.
- Cleaning last year's plants from the ridges and treating the soil with anti-fungal substances.
- Irrigation device. An excess of moisture leads to very detrimental consequences.
- Weeding the soil to prevent the topsoil from hardening.
- Observance of the inter-row distance so that the dill receives enough oxygen.
- Destruction of weeds, which are the source of fungus and infection. They are removed by weeding, but the best way is to remove and burn the root system.
- Digging the beds in the autumn to destroy the larvae that live in the ground all winter.
- Control of the sowing turnover, which helps to prevent the occurrence of fungi and diseases.
- It is best if you plant the plant in the place where the pumpkin and beans used to grow. But the main thing is that umbrella plants do not grow.
- Choosing a planting site away from conifers and shrubs.
- Consider planting a plant so that it does not grow, for example, with carrots to avoid carrot beetles.
- Organization of hedges from marigolds, wormwood or thyme. These are the simplest methods of how to distract pests from dill.
If the culprits are not diseases and insects
It also happens that, despite the absence of diseases and mechanical effects on the plant, it looks unimportant, sluggish, and loses its bright color and taste.
- Yellowness of dill
If the leaves on the plant began to turn yellow, then this may be due to:
- Dry or excessively wet soil;
- Application of cold irrigation water;
- Active exposure to the sun;
- The thickening of the plant;
- Small ingestion of nitrogenous compounds;
- Varietal features.
To fix the problem, you just need to properly care for the dill and feed it constantly.
- Drying dill
If the plant gets few useful elements, then it begins to grow poorly, dry out and lose its strength. To prevent the plant from dying, you need to do a test to check the acid-base balance of the soil and bring the indicator to a neutral mark.
In this case, it is important not to use ash, as it reduces the quality indicators. Feeding is carried out by root or superficial. Superphosphate or other strong fertilizing materials can be used.
- Bitter taste
The main occurrence of the cause may be overripe dill. A vegetable tends to accumulate various elements, even those that can give off bitterness. Mature plants become more and more bitter over time. Improper care can also lead to a bitter taste.
If there is a desire to grow dill, it is better to familiarize yourself with the preventive measures against dill diseases at the initial stage. To save the harvest, you just need to do simple actions. This will preserve the excellent qualities of taste and a neat appearance.
The most important thing is to choose the right drugs for combating pests and diseases of dill, since after some, eating dill is immediately contraindicated.
