Daffodils are magnificent bulbous plants that delight our eyes with their lush and vibrant flowering. We willingly plant these beautiful flowers on our plots, we constantly take care of them, however, unfortunately, it is far from always possible to protect these green pets from attacks of all kinds of diseases. What can these delicate and bright flowers get sick with, and how to recognize the manifestations of unfortunate ailments?

Rust

On the stalks, leaves and inner scales of daffodil bulbs, at first, tiny colorless appear, and after some time brownish or orange swelling-pustules, characterized by an oblong shape. A little later, these pustules break through, and fungal spores are released from them, easily spreading through the air and actively infecting other vegetation. Infected leaves begin to fade quickly. In addition, beautiful daffodils bloom very poorly and are noticeably weakened.

Fusarium

Infection with this scourge occurs mainly through the roots. Attacked by the disease, daffodils begin to lag behind in growth and it is extremely unimportant to develop. Their roots gradually darken, and the bulbs begin to rot during storage, subsequently drying out or rotting completely. And between the scales on the affected bulbs, a characteristic pinkish-whitish bloom is often formed.

If the infection is weak enough, then the bulbs at first glance may seem completely healthy, since they do not have any external manifestations of the disease, however, when such bulbs are planted in the soil, they either do not sprout, or the sprouts that have hatched quickly die off. The development of the pathogen is largely facilitated by the high temperature and waterlogging of the air and soil, as well as the introduction of excessive amounts of nitrogen and ammonia fertilizers.

Sclerocial rot

On the bulbs of daffodils, a whitish, somewhat cotton-wool-like mycelium appears with a huge number of brownish sclerotia, as a result of which flower seedlings either turn yellow or do not appear at all. Gradually, the rot covers the whole bulbs, and they die pretty quickly.

Botrythiasis

This ailment is well known as gray rot. Most often, it massively affects beautiful daffodils in the second half of summer, especially if the humidity of the air during this period increases markedly, and its temperature drops to fifteen to eighteen degrees.

A characteristic symptom of gray rot is massive leaf spotting - a myriad of oval or rounded light brown spots of completely different shapes appear on the leaves. And on the perianths in the places of introduction of destructive spores, watery small specks are formed, which gradually turn brown. When wet weather is established, the buds lick and become abundantly covered with grayish fungal sporulation. The development of gray rot of the necks begins, the stems slowly break, and the beautiful plants eventually die.

Courvularia

Behind such an interesting name is the wilting of young daffodils. On very small plants, as well as on young leaves of daffodils, oval specks dotted with black spores appear in the center. Subsequently, the soil fungus-causative agent of the disease also attacks the underground parts of the plants, as a result of which the daffodils quickly die.

Penicillus rot

First, spots appear on the bulbs of daffodils, painted in reddish-brownish tones, and then, when the air temperature decreases and its humidity increases, the development of gray-green pathogenic spores begins on them. The defeat of the outer scales often leads to a significant slowdown in flower growth. It is noteworthy that in most cases the development of penicillosis can be observed in those areas of daffodils that have been subjected to various mechanical damage.
