How to protect plants from low-temperature stress?
Spring frosts are one of the greatest threats to orchards and berry plantations. Temperature drops during flowering can damage blossoms and, as a result, significantly reduce yield. Therefore, proper plant preparation for thermal stress and rapid regeneration after frost events are crucial.
In modern horticultural practice, biostimulants based on seaweed extracts and L-amino acids are gaining importance. Products such as VitaFer Algi (containing Ascophyllum nodosum extract) and VitaFer Green (rich in plant-derived L-amino acids) support natural plant defense mechanisms and improve recovery capacity.
Seaweed extracts contain natural phytohormones that stimulate physiological processes, including cell division and tissue development. As a result, plants become better prepared to withstand adverse environmental conditions. Meanwhile, amino acids act as carriers of nutrients, enhance their absorption, and help reduce the negative effects of abiotic stress.
Preventive and regenerative treatments – key to minimizing losses
To effectively protect crops from frost, a preventive application is recommended 24–48 hours before the expected temperature drop. Applying VitaFer Algi and VitaFer Green at a rate of 2.0–2.5 L/ha each activates the plant’s natural defense mechanisms. As a result, flower losses can be reduced by up to approximately 30%.
After frost stress has passed, supporting plant regeneration is essential. A follow-up application 7–10 days later, using the same products and rates, accelerates tissue recovery and supports further plant development.
Impact of biostimulation on flowering and pollination
The use of seaweed- and amino acid-based biostimulants not only enhances plant resistance but also improves flowering and pollination processes. Plants develop flowers more effectively, and physiological processes run more efficiently. Additionally, improved plant condition promotes pollinator activity, which leads to better fruit set.
