Hydrurales

Hydrurales is a specific fungal disease of plants caused by microorganisms of the order Hydrurales. This pathology belongs to the group of fungus-like organisms that, under certain environmental conditions, can exhibit aggressive properties, affecting the vegetative organs of agricultural crops.

The main crops susceptible to infection include various aquatic and semi-aquatic plants, as well as some vegetable crops grown in waterlogged soil or hydroponic systems. The disease is often found in nurseries where high substrate humidity is maintained.

Symptoms of the infection manifest as the appearance of mucous coatings or specific colonies on the surface of the root system and the root collar. Plants begin to lag in growth, their leaves lose turgor and turn yellow, and in advanced stages, systemic tissue decay occurs, leading to the rapid death of the plant.

The development of the disease directly depends on hydrothermal conditions. An optimal environment for spore dispersal is excessive moisture, lack of soil aeration, and temperatures in the range of 18–25 degrees Celsius. The pathogen is transmitted through contaminated water, untreated tools, or plant debris.

The harmfulness of this disease lies in the rapid spread across plantings and the difficulty of treatment at late stages. For prevention, it is necessary to strictly follow irrigation schedules, ensure drainage, disinfect the substrate, and use only high-quality planting material. In case of outbreaks, broad-spectrum fungicides are applied.
