Rizoderma Argentina
Biological seed fungicide for disease protection and roots
RIZODERMA® is a biological fungicide for seed treatment based on Trichoderma harzianum (Th2), a highly effective biocontrol microorganism. Applied directly to the seed, it helps protect crops against key seed- and soil-borne pathogens while supporting healthy root and seedling development. Its multiple modes of action contribute to reliable disease management and extended residual efficacy.
Mode of action
Competition
Trichoderma harzianum rapidly colonizes the seed surface and developing root system, occupying ecological niches and consuming available nutrients before pathogens can establish. This early and aggressive colonization creates a protective barrier around the seedling during the most vulnerable stages of crop establishment.
Mycoparasitism
The fungus actively detects and recognizes pathogenic fungi in its environment. Once contact is established, it grows around the pathogen, penetrates its structures, and releases hydrolytic enzymes that degrade the pathogen's cell wall, ultimately suppressing or destroying the target organism.
Antibiosis
Trichoderma harzianum produces a range of natural bioactive compounds and metabolites that inhibit spore germination, pathogen development, and fungal growth. These compounds help reduce disease pressure and limit the spread of harmful microorganisms in the rhizosphere.
Plant Growth Promotion and Defense Activation
In addition to its biocontrol activity, Trichoderma harzianum promotes plant growth by stimulating root development, increasing root length, volume, and biomass. It also activates the plant's natural defense mechanisms, priming the crop to respond more effectively to biotic and abiotic stresses throughout the growing cycle.
