Sage is able to cure diseases of most organs of the human body - the list of its miraculous properties is truly limitless. That is why summer residents are so willing to grow it on their plots. Nevertheless, this unique healing plant is often affected by a wide variety of diseases. What is the sickness of the handsome sage and how to recognize the ailment that has overcome him? It's time to get acquainted with the main symptoms of diseases affecting sage

Root rot

Most often, this attack affects the underground organs of young sage, and tiny shoots are especially severely damaged. First, the lower parts of the stems darken and both root and root zones become noticeably thinner. Infected tissues begin to slowly rot, and the aerial parts of the sage are characterized by stunted growth, yellowing, as well as rather rapid withering and dying off. If the humidity in the area is increased, then an unpleasant cobweb mycelium will additionally develop on the affected vegetation. Especially intensive development of the disease is noted with sharp temperature fluctuations and in wet cool weather.

Black root rot

This ailment is common almost everywhere where sage grows, and it does not spare plants of any age at all - even newly hatched seedlings cannot be protected from this infection. Sage roots attacked by black root rot begin to turn brown along their entire length, gradually becoming covered with a dark grayish-olive bloom of mycelium and conidial fungal sporulation. Gradually, the infection leads to the death of the affected roots.

The diseased sage leaves droop and, turning yellow, dry up rather quickly, and the stems noticeably thinner and are characterized by shortened internodes. In the case of a particularly severe defeat, sage often dies. To a large extent, the development of this harmful scourge is facilitated by humid and rather cool weather, when the thermometer stably ranges from sixteen to twenty degrees. And in years with a cool, protracted spring, a massive defeat of sage is often noted.

Hollow root

Unfortunately, the exact cause of this infection has not yet been identified. Almost always, in places affected by this scourge, on the border of diseased and healthy tissues, the mycelium of fungi of the Fusarium genus, numerous harmful bacteria and even larvae of weevils are found. It is quite possible that the weevils larvae penetrating the roots carry the bacteria causing the hollowness.

Sage roots affected by hollowness noticeably thicken, and hollows filled with a rather loose mass begin to form inside them. The vascular tissues of sage gradually rupture, plant growth slows down significantly, their buds quickly droop, and the leaves gradually wither. Sick plants die very quickly - literally in one or two days.

Most often, adult sage is affected by hollowness, and this happens in the second or third year of its cultivation. Sometimes, as a result of damage to this disease, up to 70% of the plants die.

Rust

The most favorable conditions for the development of rust arise with high humidity, moderate temperature conditions and excessive thickening of the plantings. On the undersides of the leaf blades, as well as on the stalks with petioles, numerous characteristic rusty specks are formed. If a harmful disease attacks sage especially strongly, then its leaves will begin to turn yellow and fall off, and the stems will quickly dry out and break at the slightest touch.
