Global protection against stress 


Optimus® is a dual-acting formulation: it increases resistance to biotic stress caused by the attack of certain pathogens (fungus) and increases tolerance to abiotic stress (adverse climatic causes, primarily). This is thanks to the phosphopeptide content of its formulation, which give a specific response (to biotic stress), and its amino acid content, which gives a generic response (abiotic stress). 

The product acts as an activator of Pathogenesis-Related (PR) Stress Proteins, which are proteins that are expressed in a given pathogen attack. 


  • Multipurpose product that acts on biotic and abiotic stress.
  • Does not cause resistance.
  • High bioavailability.
  • Excellent compatibility.


Optimus® can be applied to all types of crops, primarily: citrus, fruit, horticulture, strawberry plants, potatoes, vines, cotton, etc.


  • Foliar application: 250-350 mL/hL.
  • Radicular application: 8-12 L/ha.


When to apply:

Preventively treat when moisture and temperature conditions favor the development of pathogens. 
The number of applications ranges between 2 and 4, and the application intervals are from 7 to 14 days.
