Diseases of phlox: treatment and prevention

Flower growers do not pass indifferently past phloxes. Flowers fill the garden with a light aroma, burn with a bright flame, attract glances thanks to the overflows in the shades of petals and inflorescences. It is customary to refer these flowers to unpretentious plants. But experienced flower growers know that often there are unpleasant diseases of phlox, the treatment of which does not always lead to a positive result.

There are several varieties of phlox. It is subulate, spread out, paniculate. If you take into account varietal features, phloxes can be planted in such a way that flowering lasts all summer. Variety of colors and the removal of bright hybrids makes the growers acquire new varieties.

But if you do not recognize the time of phlox disease, leave the focus of the disease without attention, the florist risks losing a whole collection of beautiful flowers.

Diseases of phlox flowers are transferred to a clean garden with the arrival of a new specimen. Externally, a healthy plant can bear fungal spores, infect nearby growing flowers and gradually, instead of beautiful strong bushes, remain drained from below, with dark spots on the leaves and poorly blooming inflorescences of the plant. Viruses and fungi cause terrible diseases of phlox. Treatment for them is a long, not always effective.

Causes

Weather conditions (humidity, cold dew), thickened planting, neglect of the gardener and untimely prevention lead to the reproduction of fungal diseases.

In our gardens they are enough. Spores are carried with great speed from woody plants, vegetable beds, weeds.

Varieties of diseases of phloxes

The most common and dangerous diseases of phloxes, whose treatment is belated, are able to infect growing plants nearby.

Types of fungal diseases:

• Erysiphe cichoracearum, or powdery mildew;
• Septoria phlogis Sacc, or septoria;
• Uredineae, it's rust;
• Phoma phlogis, or phomosis;
• Verticillium arboatrum, otherwise verticillium wilt stems.

Types of viral diseases:

• Variegatedness;
• Annular spotting;
• Curly;
• mosaic.

Mycoplasmosis is dangerous because it spreads even slowly, but if it gets hooked, plants need to say goodbye. So far this is a rare disease. How do phloxes of the disease, whose treatment last a long time, endure? Stoically, whenever possible try to console the gardener with blossom. But the appearance of the plant gives the presence of the disease.

Viruses - what is the danger

Viral diseases are spread by garden pests: aphids, mites, cicadas, roundworms. Plants affected by the virus can not be cured. Florists must constantly monitor the situation, inspect their flowers, know the signs of disease and fight for the survival of healthy plants.

So, when variegated, light, randomly arranged strips appear on the opened flowers. The habitual appearance of phlox changes, they become faded and stunted.

The spotted circular pattern deforms the whole plant in the last period of the disease, and at first innocent light circles on the leaves give out a viral disease.

Bushes infected with a virus of curl, twist into a spiral is the leaves, but flowers such phloxes will not please. The death of a plant is inevitable.

The mosaic "decorates" the leaves with stains of irregular shape, the food of the plant deteriorates, a lot of effort is expended, the phlox gradually dies in unequal struggle.

Fungal diseases - we will treat

White patchiness and rust differ only in the color of the spots. Appearing on the leaves of the phlox paniculate white, gray-brown or bright brown irregular spots, gradually deplete the bushes, the lower leaves dry out. The disease progresses rapidly, passes to other specimens. Struggle can be effective, enough once in 7 days to process bushes Bordeaux mixture. Florists study phlox diseases and their treatment. Photos of affected flowers often help in the diagnosis of viral and fungal diseases.

Verticalella wilt stems (wilt) gardeners are called "lightning". Wilt infects plants during the flowering period, the leaf dries very quickly, the bush looks not aesthetically pleasing. Stems tolerate the disease, and the root system is covered with a white or brownish coating. If you are late, the disease will destroy the entire flower bed. Fungus, the causative agent of wilt, falls into the soil with acid filings, dung earth. Propagates on acidic soils. Liming and processing with the ash solution will not allow the wilt to develop. But if this has already happened, it is necessary to remove the plant from the ground, cut the bush and wash the roots in a disinfectant solution. Suitable for any drug against fungal diseases, for example, "Fitosporin."

Phloxes pick buds, be careful

Virtually all diseases of phlox are actively progressing during budding. Fomoz is no exception. The plant changes appearance , the leaves shrivel, and the stem is covered with cracks. The fungus penetrates into the tissues, the branches become brown. The disease recedes if 1% Bordeaux fluid is introduced into the soil late in the autumn and early spring. Fomoz put into the soil are able to manure with mold, untreated sawdust. The fungus quickly infects the plant. The phloxes of the disease are suffering.

Treatment (photo of the treated plants confirms this fact), fortunately, it works. It can be seen that the upper young leaves are healthy.

Brown spots and spots on the leaves appear from septoriosis. Phloxes turn yellow, leaves are framed in brown color or purplish. The trunk is bare, the sight of the diseased bush is not pleasing. But the disease will weaken from the therapeutic spraying of a dilute mixture of lime milk and copper sulfate in water. Three sprayings at intervals of 7-10 days are sufficient for the disease to go away. Missed the chance, cut out the stalks and burn them. The land is watered with copper-containing lime 1% solution. If phloxes are taken care of, and the diseases recede, and no adversity will prevent the blossoming.

Insidious white dew

Everyone is accustomed to believe that powdery mildew affects the tender and juicy leaves of peppers, cucumbers. Phloxes though have a solid stem, but can not stand before this insidious fungus.

White coating appears on plants in the form of scattered careless flour. It grows very quickly. The color of the dense, suede coating changes. It becomes brown or gray, it depresses the plant. The leaves begin to dry up, the breath of the plant ceases. The plants are often affected during the wet summer period. Infected flowers are spores of the fungus Erysiphe Cichoracearum. Suffer from the disease all parts of the plant, located above the ground.

The spread of the disease contributes to overfeeding plants with nitrogenous fertilizers in the spring. The pampered bushes are not capable of fighting such an affliction. Any phloem diseases are dangerous. Powdery mildew (a photo with a white bloom on the leaves) is the most dangerous of them.

Care

Creating phlox mixborders, first of all, you should prepare the soil for planting. Soil these flowers prefer friable, neutral, nutritious, air-permeable. It is not recommended to fill it with fresh manure. These handsome men will be approached only by a well-blamed, three-year-old manure. Fertilizing during the summer in the doses indicated on the fertilizer pack strengthens the paniculate phlox.

The benefits of fertilizing with mineral fertilizers are obvious: when plants receive timely nutrition, they get less sick. Elimination of excessive acidity of the soil, drainage from flower beds in rainy season and watering in the dry period, give plants a chance to avoid insidious diseases.

Prevention

Treatment with a Bordeaux mixture twice a year will not allow fungi to spread. Spraying "Epin" will strengthen immunity. A good result is the pruning of the tops during the rainy season. This pushes the flowering period. If the florist conducts timely treatment of phlox disease, powdery mildew can not cause harm.

Any suspicion of the disease requires precautionary measures. Treatment with ashes, Bordeaux liquid, antifungal agents will help prevent an ailment.

In the autumn, branches break off and are burned, the bush is mulched, and is covered with earth. Damaged frost, protruding from the ground roots of phlox can damage the health of the flower.

Treatment or farewell

Even the best and most experienced florist has periods when preventive measures are not enough, and illnesses win. Intensive, systematic treatment preserves part of the plants. Fungal diseases can still be tried to treat.

If there is a place, it is better to plant the bush by transshipment, and treat for 3 weeks. Treatment does not work? Without regret, destroy the plant and do not risk the whole collection of its flowers.

We noticed that the culprit of phlox disease in the flower garden is a virus - a plant in a fire. Why is the recommendation so categorical? Otherwise you can not. No infection can be transferred for a fence, compost, or neighbor. She will return to your flower bed very quickly.

If fungal diseases of phlox are found, treatment will be gentle. Flowers successfully recover with proper care. The main thing is to find the hearth and destroy it, to decontaminate the soil.
