Diseases of roses

Most often roses suffer from mealy dew, a rust, black spottiness, gray decay, infectious "burn". It is difficult to treat diseases, try to take all measures that to prevent them. Here about it the speech in our article will also go today.

Having got saplings of high-quality roses, having put them at the dacha, you realize soon that a flower this really royal. Because attitude towards himself he demands the special. And if you wish that roses decorated your flower bed with the beautiful look, it is necessary to indulge their whims and requirements. The rose needs the solar place, fertile soils which are well trained of top dressing in certain time, plentiful and correct watering, periodic cutting … The slightest inattention to "queen", the made mistakes in leaving can lead to diseases. Bacteria, disputes of fungi, viruses and insects wreckers after all do not doze. The general important recommendation which wants to give InfoAdvisor.net to the readers wishing to have healthy rosebushes on a site are the correct agrotechnology. To the strong plants growing in good conditions, diseases will not creep. And here special means will help to frighten off insects. Certainly, it is necessary to begin with the sparing preparations. And here get serious chemical means only when your any efforts do not help, and the illness continues to progress, doing harm to your favourites. And before use attentively study the instruction that strictly to adhere to it.

Preventive actions

Near with roses we plant the plants having a strong smell thanks to existence in composition of essential oils. These are natural otpugivatel of insects wreckers. The calendula, barkhatets, a nasturtium, a sage, decorative onions belongs to such plants.

  1. Examine the pets more often, at the slightest doubts and symptoms of an illness already take measures.

  2. Periodically, in the late afternoon, spray and water plants with warm infusion of a calendula, yarrow, onions peel. Garlick shooters suit for these purposes also.
  3. From the middle of summer we dust the bushes wood ashes by means of a sieve.
  4. Surely carry out cutting, the zagushchyonnost of a bush can provoke fungal diseases.
  5. Delete the leaflets having specks and burn.
  6. It is possible to use good homeopathic assistants: the preparation "Ekoberin" (that roses got accustomed when landing) and "A healthy garden" better (for pest control). Resistance to diseases will give to your jewelry of a garden an irrigation freshly cooked solution to which "Zircon" or "Epin" is added.

Of that to be afraid in the summer

Active tripsa and listovyortka can absolutely deprive bushes of leaves and even buds. In June young pink leaflets are very attractive to a plant louse, she literally exhausts all juice from a plant. You will find many means of fight against it in sale. But pay attention, whether is not present nearby with ant hill roses. Ants grow up a plant louse, she at them is a source for a sweet nutritious siropchik. Sometimes it turns out so that the gardener a plant louse extinguishes, and it is again presented by ants.

One more misfortune during a heat – a web tick. It harms not only to roses, but also currant, apple-trees. The preparation "Neoron" has selective impact on this tiny insect. But process by all means the lower parts of leaves, this wrecker exactly there lives.

Provocative factor of diseases – rains

Rainy weather very much is pleasant to mealy dew. The activator – the fungus striking chashelistik, sheet plates, escapes is much more rare – buds. Emergence of reddish-purple specks on young leaflets has to guard gardeners. On the struck bodies it is possible to notice a white web raid. Leaves are deformed, morshchinitsya, dry up and fall down, and on all length of stem escape there are friable felt small pillows are a mycelium. The decorative species of a bush, its winter hardiness spoils, and the plant can be lost. Progressing of mealy dew, except the increased humidity of air, is promoted by such factors: a zagushchennost of bushes, a lack of a sunlight, excess of nitrogen in the soil, shortage of potassium in it.

As measures of fight I will offer the following:

  • not to allow a zagushcheniye of landings, periodically to cut off them;
  • correctly and in due time feed up plants;
  • spraying by infusion of a horsetail or garlic will help with an initial stage of an illness;
  • growth of a fungus is interfered by colloidal sulfur and preparations which part it is;
  • use of other fungicides, for example, a biological product of "Fitoftorin" (processing to spend each 10 days).

The rust of roses – too a fungal disease, weakens a plant, strikes all its elevated parts, leaves early fall down, escapes dry up. In May it is possible to notice orange spots about kidneys, on stalks, young leaves, scapes. On these spots black borodavochka are visible. Disputes of a fungus continue to extend on other parts of a bush. In July of a spot expand, disputes raise dust even more. Rains strengthen development of a fungus. Surely delete sick escapes, other parts of a plant. It is necessary to spray bushes bordeaux liquid, and in the summer periodically process everything fungicides in the fall.

Gray decay. The causative agent of this illness of roses strikes their buds and flowers. The fungus covers sick fabrics in the period of rains with a gray raid, they decay. Leaves of a plant turn yellow, then fall down, buds can not reveal at all. Or flowers will be with ugly brown spots. Try to warn an illness fungicides in advance to avoid such troubles.

Tests for roses in the fall and during wintering

Fogs, low temperatures at night days, cold dews – all this prerequisites for emergence of black spottiness. Its activator is too the fungus therefore carefully collect the struck parts of a plant and burn to prevent further distribution. Also spray plants antifungal means, that is fungicides. Process the soil a copper vitriol (3% concentration of solution) before hill in the fall a plant and to cover for the winter.

And now we will a little talk about infectious "burn" which arises on stalks. Influence of a frost, mechanical damages and late entering into a soil layer of nitric fertilizers can be the reasons of its emergence. If in winter shelter humidity and bad ventilation is increased, some escapes perish. If cutting was carried out to wet weather, roses covered too early or were late with their disclosure in the spring. Then on escapes it is possible to see reddish (or brownish) spots at which core is more dark, gradually there is a growth of these spots and dying off of vegetable fabric.

The mistakes of gardeners provoking diseases

Often gardeners make a sapling choice only on appearance of butonchik and flowers. Consult at the knowing flower growers before choosing a grade for purchase. Get hardy and steady grades. Well proved roses Scarlett Meyan Dekor, Leonardo da Vinci, Pulman Oriyent Express. Skilled flower growers say that Solidor, Rafaello are very subject to all misfortunes of a rose.

Do not plant a rose in a shadow.

If roses place about big trees, their powerful roots will take away nutrients and moisture from bushes.

Put at dacha much, gardeners often give in to such temptation as watering by means of the pump moreover and cold water from a water supply system. For roses such irrigation is inadmissible! Water the roses correctly, only warm water which heated up in a day in a flank and under each bush. Then will be much less prerequisites for fungal infections.

One more mistake – diligent introduction of urea, and after all too conducts excess of nitrogen to diseases. After the top of summer it is better not to bring nitrogen. Closer to fall plants need potassium and phosphorus better to be prepared for wintering.

Do not carry out cutting by the raw and blunt tools. Do not forget to grease cuts of stalks with Novikov's liquid (or the special garden thief).

There can be a reasonable question – and whether people should be afraid, careful of sick flowers? At once I will calm you – diseases of these plants for people do not constitute danger. But be careful during the work with means of processing of roses, accurately follow instructions of the instructions attached to them. Carry out all work in the overalls allocated for such cases, and then well wash up the hands.

The success of pest control or diseases depends and on vigilance of the flower grower. The quicker you will find the first symptoms, the quicker will be able to take necessary measures of influence and will rescue the favourites. Be attentive and patient at care of roses. And still pleasant news from InfoAdvisor.net: selectors continue work on new grades of roses that care of them was easier.
