Brachionids
The Brachionidae family, belonging to the Rotifera phylum, consists of microscopic organisms that can act as opportunistic pests in agricultural environments. In greenhouse production, these organisms thrive in environments with excessive moisture, where they inhabit the thin film of water on plant surfaces or in saturated growing media.

Brachionids
These pests primarily affect nursery stock and greenhouse-grown plants that suffer from poor drainage and high humidity. While they do not consume healthy plant tissues directly, their biological activity facilitates the breakdown of plant matter and the colonization of roots by secondary fungal and bacterial pathogens.
The biology of Brachionids is defined by rapid reproduction and high adaptability to aquatic environments. Through parthenogenetic reproduction, populations can explode in number within a few days if conditions such as stagnant water and decomposing organic debris are present. This allows them to quickly dominate the micro-ecosystem of the root zone.
Damage caused by Brachionidae is indirect but significant, manifesting as localized necrosis of roots and stem bases. By damaging the surface tissues of plants, they create entry points for soil-borne pathogens. This leads to symptoms such as stunted growth, chlorosis, and the sudden collapse of seedlings due to root rot.
Managing Brachionidae requires strict adherence to good agricultural practices:
- Optimizing irrigation to prevent waterlogging.
- Improving greenhouse air circulation and ventilation.
- Using sterilized growing media for propagation.
- Maintaining strict sanitation by removing decaying plant matter.
- Regular cleaning and disinfection of irrigation systems and containers.
