Flowering is one of the most decisive stages in the life of fruit and

Managing stone fruit crops increasingly demands solutions that go beyond traditional nutrition and basic crop protection. Microbial bio‑stimulation has emerged as a sophisticated agronomic tool capable of fine‑tuning plant physiological and structural responses, enhancing growth, stress resilience, and fruit quality when applied during key phenological windows. The Ekky line from Probelte offers an integrated bio‑stimulation strategy based on selected microorganisms, formulated to act from the root zone through to the fruiting organs, driving robust agronomic responses in stone fruit systems. 1. What is Bio‑stimulation and Why It Matters in Stone Fruit? In stone fruit species — such as peach, nectarine, apricot, and cherry — stages of active growth, flowering, and fruit set

Brown rot (Monilinia spp.) is one of the most limiting diseases in stone fruit crops, particularly in peaches, due to its direct impact on fruit quality and the economic losses it causes both in the field and during postharvest. Under favorable humidity and temperature conditions, the disease can lead to: At the same time, the growing demand for more sustainable crop protection strategies is driving the need for effective biological solutions capable of reducing residues while maintaining crop profitability. Trial context The trial was conducted in a commercial peach orchard of the variety Rojo de Albesa (Prunus persica) under field conditions in: Alfarràs (Lleida, Spain) Season: March – October 2016 Crop conditions: Disease pressure during the trial ranged from moderate to high, with a uniform distribution across the plot, providing strong reliability and representativeness to the results obtained. The study was carried out by the specialized research company PHYTEST
