URANSER® is a fungicidal product based on potassium phosphonate, designed to control Phytophthora spp. in stone fruit trees (peach, nectarine, and flat peach). It is recommended for application via localized irrigation or foliar spray.

The mode of action of URANSER® involves activating various defense mechanisms, or SAR (systemic acquired resistance), strengthening cell wall structure, and stimulating the synthesis of phytoalexins, PR proteins, and polysaccharides. Additionally, it directly affects the pathogen by modifying the expression of genes that code for structural protein synthesis, inhibiting its growth and development. URANSER® also has a nutritional function, resulting in stronger and more resilient plants.
