SWEET

Biochemical Mechanism of Ripening Acceleration

The SWEET preparation from the Italian manufacturer Valagro relies on the synergy of polysaccharides, calcium, and microelements acting as a specific metabolic activator. Unlike standard fertilizers, SWEET does not just provide nutrients; it triggers the synthesis of natural sugars and anthocyanins directly within the fruit tissues. The primary goal of this formulation is to intensify plant metabolism during the yield formation phase.

Key Components and Their Functions

• Polysaccharides: serve as an energy substrate for ripening processes, ensuring uniform sugar accumulation (Brix levels) and flesh firmness.
• Calcium: reinforces cell walls, which is crucial for sugar transport and improving the shelf life of vegetables, fruits, and berries.
• Microelements: act as catalysts for enzymatic reactions responsible for coloration and organoleptic quality.

Application Technology

The product is supplied as a liquid solution, ensuring immediate absorption through the leaf surface. Foliar application delivers the components directly to the synthesis 'depots'—the fruits. To achieve the best results, 1–3 applications are recommended during the ripening period. The application rate ranges from 2–5 L/ha, depending on the crop and the intensity of the cultivation program. Due to its Class 4 toxicity rating, SWEET is a safe tool for producing goods that meet the stringent requirements of the fresh produce market.

Practical Impact

Using SWEET allows for the shortening of harvest time by 2–5 days and helps negate the negative impact of weather conditions (lack of sunlight or temperature fluctuations) on sugar accumulation. The result is produce with enhanced organoleptic properties, high firmness, and superior visual appeal, which directly contributes to higher profitability when selling fresh vegetables, berries, and fruits.
