Aterix Argentina
Biological fungicide for broad-spectrum foliar disease control
Aterix is a biological fungicide formulated with Trichoderma afroharzianum (Th2RI99), a proven biocontrol microorganism widely recognized for its ability to suppress a broad spectrum of foliar pathogens. Applied directly to the crop canopy, it helps reduce disease pressure through natural biological mechanisms that limit pathogen establishment, growth, and spread.
In addition to its protective effects, Aterix contributes to overall plant health by promoting a more balanced crop environment and supporting plant resilience under disease pressure. Its biological nature makes it a valuable tool within integrated disease management programs, helping growers protect yield potential while advancing more sustainable and environmentally responsible production practices.
Mode of action
- Competition: Following foliar application, Trichoderma afroharzianum rapidly colonizes the plant surface, competing with pathogenic fungi for space and nutrients. This biological occupation reduces the ability of pathogens to establish and proliferate on plant tissues.
- Mycoparasitism: The fungus directly attacks susceptible pathogens by growing around and penetrating their structures. Through the secretion of lytic enzymes such as chitinases and β-1,3-glucanases, it degrades pathogen cell walls, suppressing growth and causing the death of the target fungus.
- Antibiosis:Trichoderma afroharzianum produces a diverse range of volatile and non-volatile antimicrobial metabolites that inhibit the development of pathogenic fungi. These naturally occurring compounds help reduce disease pressure and limit pathogen spread within the crop canopy.
- Induction of Plant Defenses:The fungus stimulates the plant's physiological and biochemical defense pathways, triggering Induced Systemic Resistance (ISR). This enhanced defensive state enables the plant to respond more rapidly and effectively to pathogen attacks, contributing to improved crop health and disease tolerance throughout the season.
