Fusariosis is a serious disease affecting many plant species, particularly those to which the vascular system plays a key role in the transport of water and nutrients. This disease is caused by fungi belonging to the genus Fusarium, with species such as Fusarium oxysporum attacking plants through the roots or through pre-existing lesions, impairing the functionality of the xylem system.
Characteristics of Fusariasis
Fusarium disease is manifested by invasion and obstruction of the vascular system. Once the pathogen penetrates the tissues, it spreads within the plant, preventing proper transport of fluids and nutrients. Initially, the infection causes mild chlorosis; leaves lose their vigor and take on yellowish or brownish hues, a sign of compromised internal balance. As the infection progresses, there is marked wilting and the formation of necrotic areas, until the plant shows obvious signs of stress and, in extreme cases, may suffer a total loss of viability.
Infectious cycle and mode of spread
The infection cycle begins with the release of spores into the soil, where the pathogen can persist for long periods due to resistant structures. When environmental conditions are favorable, the spores germinate and the mycelium develops, heading toward the root system. Entry into the roots, aided by any wounds, allows the fungus to expand internally and reach vascular tissues. The combined action of overwatering and high humidity conditions facilitates the spread of the disease, especially in already contaminated soils, making it difficult to manage the disease without constant monitoring.
Clinical manifestations of fusariosis
The manifestations of fusarium disease occur in a progressive manner. In the early stages, plants show a reduction in viability and photosynthetic capacity, visible through yellowing of leaves. As the infection progresses, the compromised vascular system induces wilting and necrosis of areas of leaf tissue, a phenomenon that leads to premature plant organ failure. Roots, on the other hand, may appear enlarged and altered in coloration, highlighting the presence of an invasive mycelium that has altered the internal structure. The distribution of symptoms is often asymmetrical: some parts of the plant may remain relatively intact, while others suffer significant damage.
Digital monitoring of fusarium disease with Plantvoice®
Early detection is essential to contain Fusarium infection and limit crop damage. In this area, the use of sensors and digital platforms plays a crucial role. Plantvoice® stands out for its ability to integrate physiological and environmental data, enabling real-time detection of abnormalities that anticipate the onset of fusarium infection. Sensors, strategically placed close to the roots and near critical tissues, constantly monitor water flow and sap composition. When measured parameters deviate from normal values, the system generates an alarm indicating the possible presence of infection.
This methodology based on data analysis allows early detection of changes, enabling targeted and timely interventions. The digital platform processes the collected data using advanced algorithms, providing a detailed and localized view of plant status. In this way, it is possible to intervene only in at-risk areas, optimizing resources and limiting the spread of the pathogen without having to resort to generalized treatments.

FAQ – Frequently Asked Questions about Fusariasis.
- What is fusariosis and what pathogen causes it?
Fusarium is a wood disease caused by fungi of the genus Fusarium, which attack the vascular system of plants. - What are the first symptoms that indicate the presence of fusarium?
Initially, widespread chlorosis and reduced leaf viability are observed, followed by wilting and tissue necrosis. - How does the pathogen responsible for fusarium spread?
Spread occurs mainly through contaminated soil and by mechanical injury in roots, facilitated by high humidity conditions. - How does digital monitoring help detect fusarium disease?
High-precision sensors monitor water flow and sap composition; abnormalities in these parameters signal the onset of infection at an early stage. - What advantages does a system like Plantvoice® offer in managing fusarium disease?
Plantvoice® enables early detection of changes in physiological parameters, providing localized data that support targeted and timely interventions to contain infection.
