Diseases of pumpkin in the open field: description and treatment
Pumpkin can become infected with a virus or fungus both in the garden and in the greenhouse, or during the period of growing seedlings. Some diseases appear during the growth period, others during the ripening of the crop. In this article, I will teach you how to do it right. and most importantly, to start the fight against diseases in a timely manner.
Eliminate pumpkin root rot
Root rot, as a dangerous pumpkin disease in the open field, tends to infect young seedlings or bushes that have recently been planted in the garden. The roots darken, and the leaves, in turn, wither and turn yellow. Watering plants with cold water or sudden changes in temperature, as well as very acidic soil, can provoke root rot. Prevention of this disease consists in observing the rules of crop rotation. I also strongly recommend that you disinfect the soil well. If root rot has already hit the roots of the plants, the bushes need to be instantly treated with a solution of sulfur zinc, you can also use Bordeaux liquid. Before starting treatment, be sure to wear protective equipment such as gloves, a gown and a respirator. In order to significantly reduce the acidity of the soil, before planting, it is necessary to sprinkle the earth with lime and ash. The ingredients must be mixed one by one.

Powdery Mildew Pumpkin Disease: Treatment
If large white spots have formed on the leaves, which gradually spread throughout the plant, rest assured - this is powdery mildew. The main causes of this disease are pumpkins, weeds and contaminated soil. The very high nitrogen content in the soil also contributes to the development of the disease. Powdery mildew spreads through the plants with the help of water and wind. You can cure the fungus with the help of mullein infusion or ground sulfur. To prevent the occurrence of infection, you should constantly weed and loosen the beds. Powdery mildew treatment is best done in the morning in order to reduce the risk of burns on the plant.
Peronosporosis - a dangerous pumpkin disease

The fungus of downy mildew is nothing more than downy mildew. The leaves are covered with yellow - brown spots and the plant gradually dies. Insects such as slugs, aphids and whiteflies spread this infection throughout the garden. In order to reduce the risk of peronosporosis, you need to carefully dig up the garden bed and remove all residues of plant debris. Then treat the soil with special preparations, I usually use "Gamair" or "Fitosporin". Bushes are best planted at a distance; planting should not be thickened. If the fungus has already settled in your garden, treat it with copper sulfate. It should be remembered that if you find a fungus in a timely manner, then you have a better chance of saving the pumpkin harvest.
Copperhead pumpkin disease: treatment
Foxes are covered with brown spots, which gradually increase in size, do not hesitate - this is anthracnose, in the common people a copperhead. The causes of such a pumpkin disease as copperhead are very simple, temperature drops or burns on plant leaves. If you start the disease, then it will gradually spread throughout the plant. Ulcers form on the stems, which dry out and begin to crack. The pumpkin dies, and its harvest becomes unsuitable for human consumption. In order to prevent the development of the disease, the soil should be fertilized with complex mineral fertilizers. Very delicate and sensitive pumpkin varieties are best planted in a greenhouse or greenhouse. You need to treat the fungus with special drugs that are sold in any store. Dear gardeners, remember, you need to strictly observe the dosage of the drug so as not to harm the plant. If the pumpkin grows in a greenhouse or greenhouse, you should regularly ventilate and water it strictly on schedule. Very high humidity and stagnant water create very favorable conditions for the emergence of copperhead.

Treatments for green spot pumpkin disease
This pumpkin disease is spread by water and wind. As a rule, the disease intensifies around mid-summer, just at the time when harvest time is approaching. Light or dark brown spots appear on small pumpkins, which gradually begin to crack. In order to avoid the occurrence of infection, choose disease-resistant pumpkin varieties. Planting this crop is best done in seedlings. For growing seedlings, he chooses only large and heavy seeds, and we process them in aloe juice or in a manganese solution. Then we harden the seeds, put them in the refrigerator for a couple of hours and so on for five days. If, nevertheless, the pumpkin has become infected with the green spot virus, it should immediately be sprayed with the bushes with Bordeaux liquid or special preparations.
Yellow mosaic and treatments for this pumpkin disease

Pumpkin disease very often affects young plants. The leaves take the shape of a tube and are covered with a whitish bloom. In an adult plant, the disease can be identified by yellow patterned spots. Pumpkin bushes immediately lag behind in growth, the plant becomes stunted. Pests and poorly cultivated or insufficiently fertilized soil are carriers of this infection. Preventive measures for this disease are very simple, careful care, timely watering and feeding is the key to success. Diseased plants can be cured with a solution of korbaphos. If the focus of infection has arisen in a greenhouse or greenhouse, after the entire crop has been harvested, remove the top layer of soil, about 15 cm. Then treat the entire greenhouse with a 0.5% solution of trisodium phosphate. The clothes in which the processing was carried out should be boiled, since the mosaic virus can easily persist on it and not die within two years.
Sclerotinia as a pumpkin disease outdoors
Sclerotinia is nothing more than white rot. This fungus occurs on both young shoots and adult plants. This viral pumpkin disease multiplies with the help of fungal spores. Spores become more active during very hot or too rainy climates. In diseased plants, roots and foliage immediately begin to rot. A white bloom appears at the base of the stem, which vaguely resembles fluff. If you find this attack on your site, sprinkle the beds with wood ash. After that, you should feed the soil. I usually feed with zinc or urea. Copper sulfate is also perfect as a fertilizer. This fungus is very active in hotbeds and greenhouses.

Pumpkin disease Bacteriosis: treatment
The most common and perhaps the most dangerous disease for horticultural crops.Ulcers form on the foliage. These ulcers provoke a quick death of plants. Pumpkin fruits take on outlandish forms and become completely unsuitable for food. There are a lot of reasons for the occurrence of infections - diseased seeds, residual plant debris, frequent does and too dense plantings. Watering with cold water can also accelerate the spread of infection. If you find infected plants in your garden, they are immediately eliminated and buried away from the site. The same must be done with the fruits. Bushes that did not have time to infect the fungus need to be treated with copper sulfate, and then sprinkled with lime.
Fusarium wilting as a terrible pumpkin disease in the open field

If your garden is struck by fusarium wilting, then you will immediately understand this. The roots and stems of the plant weaken and become very thin and brittle. If the summer is very dry, the foliage becomes dry and yellow. The fungus penetrates the plants through the roots, and water is the carrier of the misfortune. In order to prevent the spread of pumpkin disease throughout the site, it is enough to take very simple, but necessary measures. Before planting the pumpkin, the seeds should be treated with a growth stimulant and sprayed with milk and iodine.
This pumpkin disease is nothing more than dry black spot that occurs on ripe fruits. The melons crop is covered with dark, dry spots that gradually spread throughout the fruit. This fungus can appear both on growing crops and on those already harvested. The pumpkin begins to die due to improper storage conditions. So that this fungus does not appear on your harvest, the pumpkin fruits must be wiped with a dry cloth and stored in a dry, well-ventilated area. The crop should be constantly inspected for signs of infection. We eliminate the infected fruits, I do not recommend eating them.

If you notice dry foliage, plaque, sores or dark or brown spots on the plants, this means that your garden is infected with an infection and needs good care and feeding. We will now consider the most common symptoms that will help you understand that the plant is sick:
- If the plant has acquired white spots or in the summer, this indicates that the soil has an excess of mineral fertilizers. As a result, powdery mildew or fusarium begins to appear.
- The brightest manifestations of copperhead or root rot are bushes that begin to wither. The same reason may be non-compliance with crop rotation. The pumpkin fruit becomes soft, watery and unsuitable for food.
- Fruits that are deformed or damaged indicate the appearance of bacteriosis.
- If your crop began to grow moldy, then do not hesitate to overflow the plant and watering should be reduced. If this is not done, the pumpkin runs the risk of getting brown spot.
- If yellow patterns appear on the leaves of the pumpkin, then do not hesitate to have a yellow mosaic on your garden bed. Start urgently treating the beds with a solution of wood ash or Bordeaux liquid.
- The appearance of abscesses on the plant tells you that the pumpkin is sick with root rot or fusarium. The disease can occur due to untreated seeds or if crop rotation is not followed. Poorly treated soil can also become a causative agent.

Perhaps the most important and necessary stage of plant care is prevention. Prevention and only it allows you to grow a healthy, plentiful, and most importantly tasty harvest. I want to tell you about the most important steps in the prevention of pumpkin diseases:
- strictly follow the non-tricky rules of crop rotation, plants should not be constantly planted in the same place. This can provoke the appearance of fungi and the appearance of pests.The pumpkin grows very well in areas where beans or parsley used to grow. The most unsuccessful predecessors are melons;
- regularly carry out preventive treatment of inventory, soil, planting material and of course clothing. Disinfection is carried out with manganese, there is nothing complicated in this process;
- very strictly monitor the seedlings that you are going to plant. Fertilize, water, and treat immediately if necessary. Seedlings must also be hardened;
- take proper care of the plants, constantly weed, and loosen the soil;
- constantly carry out top dressing that plants require at one time or another. Carry out prophylaxis against diseases and pests;
- constantly inspect the garden for the presence of diseased plants or insect pests;
- if you notice that the pumpkin disease has overtaken, immediately start treatment.
We fight pumpkin pests

The most common pumpkin pest is the melon aphid. Very small, almost colorless bugs that settle on the back of the leaf. Aphids feed on plant juices of the plant, which worsens the condition of the pumpkin. The foliage first curls, then gradually fades. With a lack of juices, the ovary and flowers fall off, the pumpkin ceases to bear fruit. If you delay the fight against the pest, you can decide on almost the entire harvest. In order to get rid of this pumpkin pest, I use the proven drug Consento.
In addition to aphids, you can also find a sprout fly in the pumpkin patch. As a rule, the fly itself, as a pumpkin pest, is not dangerous, its larvae are dangerous. The larvae feed on seeds and young shoots of pumpkin. The sprouting larva destroys 50% of the seedlings in a few days. In order for the sprout fly to disappear from my beds, I use "Fentiuram". This drug should be diluted strictly according to the instructions.
Very often the pumpkin is attacked by wireworms and slugs. High humidity or neglect of the rules of crop rotation can provoke the appearance of these pests. In order to protect your crop from the invasion of pests, you should carefully process the seeds and regularly apply organic or mineral fertilizers to the soil. Bushes should be formed, but planting should not be thickened. A very large number of insect pests can be seen as they are quite visible. Therefore, I strongly advise once a week, very closely and carefully inspect your plantings. This will allow you to react in time to the appearance of diseases or pests of the pumpkin.
Pumpkin disease begins with non-observance or neglect of the rules of care or sudden changes in temperature. Many diseases appear almost immediately in the form of gray or white spots on the stems or leaves of the plant. The most important preventive measure against pests and pumpkin disease in the open field is to disinfect the soil and thoroughly treat the seeds before planting. Do not forget about fertilizers, outside root dressing are reliable protection against infections and fungal diseases. Top dressing for the root system will allow the plant to develop stronger and more productive. If you find signs of any disease on the pumpkin fruits, eliminate them immediately. The crop that was left untouched by the infection must be treated with fungicides or traditional methods should be noted.
