Akarbio is an enhancer of the plant’s endogenous resistance. Its applications promote in the plant a quick and long-lasting accumulation of molecules with functions related to stress-resistance. This allows the metabolic functions to remain unaltered, with interesting productive responses even in the presence of stress factors. Akarbio also improves the use of calcium thanks to an important Boron content and optimizes the final colour of the fruit, promoting an improvement in the final yield quality.
