The quantity and quality of winter onion and garlic yield depend directly on how the leaf apparatus forms in spring. The spring growing period of these crops in 2021 has a number of features to take into account when preparing the first foliar feeding: the slow rise in temperatures is a restraining factor for root and leaf development, and the moisture regime, though sufficient for the start, also creates favorable conditions for the development of the most harmful diseases. We therefore recommend carrying out the first foliar feeding of plants at the 3–4 leaf stage with the tank mix GROS Phosphito-NP 2.0 l/ha + ECOLINE Universal Growth (Amino) 2.0 l/ha.
These compositions contain all the active substances needed for a powerful start:
- amino acids to soften the effect of temperature stress;
- phosphorus in the form of phosphite activates root system growth and provides a clearly expressed fungistatic effect;
- microelements chelated with EDTA activate physiological processes in plants.
