Diseases of parsley - such a plant is very susceptible to all sorts of diseases. Therefore, despite the seeming ease of care, parsley should be given a lot of attention if you want to get a decent harvest.

A variety of diseases can affect parsley, but storage rot can be particularly damaging to your crop. In this article, we will talk about the diseases that parsley is prone to and how to deal with them correctly.

The most dangerous disease is powdery mildew. Such a disease becomes noticeable on leaves, cuttings, inflorescences and stems. The disease appears as a white powdery bloom. Where there is this plaque, black spots appear over time, more like black dots. These will be the fruiting bodies of the fungus. The plant acquires elasticity and fragility, there is a reduced content of sap in the plant itself. Outwardly, parsley does not look very aesthetically pleasing, and its taste leaves much to be desired. In diseased plants, reproductive capacity will be reduced. This disease usually manifests itself closer to the end of the summer season. For a favorable course of this disease, rainy weather is necessary, when day and night temperatures are very subject to fluctuations. In winter, the pest remains on plant debris.

Another important disease will be black rot or alternaria. Such a disease can attack plants in almost any period of their growth and development. Early germination disease manifests as black leg, another important disease. The root collar is primarily affected, and then the parsley begins to turn yellow and, in the end, the plant dies. Then, on adult diseased plants, the so-called mold-like plaque becomes noticeable. First, the disease begins on the leaves, then moves to the petioles, and after that, the roots are also attacked last. Initially, small spots appear on the root crops, and over time, the entire root crop is affected. Such a root vegetable cannot be used for seed purposes. If the weather conditions are favorable for the development of the disease, then the fungus will infect all organs of the plant.

As for a disease such as gray rot, it will affect root crops already during the storage period. The diseased root vegetable becomes soft and wet, and in color it acquires brownish-gray tones. The disease develops by spores, so this disease can very easily go to mass distribution. The disease can also develop when there is contact between sick and healthy cultures. The spores will be airborne, so almost all plants in the garden can be affected.

The greatest danger for the development of this disease is posed by already diseased plants, on which damage is noticeable. The optimum temperature for the development of such a disease will be minus one degree. Airing the room is the most effective method of combating this disease; such measures are a very important prevention. The causative agent of this disease will be stored in the form of sclerotia, which is the source of this disease in the soil in storage.

There is also a very important disease known as white rot. Such a disease affects not only crops, but also the weeds themselves. In terms of symptoms, the manifestation of this disease is similar to gray rot. The difference between these two diseases is that the diseased root crop does not change in color in any way. Initially, this root crop disease begins to manifest itself during the growing period. The development of the disease is very slow, so it is not always possible to see the presence of this disease in time.

Methods of combating all of these diseases will be strict adherence to competent crop rotation, harvesting plant residues and fertilizing with phosphorus-potassium fertilizers. Before sowing, it is recommended to treat all seeds with a solution of potassium permanganate.
