FOLIAR FEEDING OF RAPESEED IN SPRING
This spring's weather is marked mainly by insufficient rainfall for winter crops, rapeseed included.
This season's temperature regime is far from ideal for the crop. Fairly high daytime temperatures and night frosts will provoke damage to the basal part of the plants with the formation of microcracks through which pathogens causing rots will enter. In the traps set to determine the economic pest threshold, an increase in the population of the cabbage seed weevil, one of the most harmful insect pests of this crop, is clearly visible.
What should agronomists do in this situation? Based on field trial results, ECOORGANIC recommends that, together with insecticide and fungicide protection, foliar feeding with special fertilizers containing the following active substances be applied:
- Phosphorus in the form of phosphite to stimulate root system growth, to make the plant produce phytoalexins that suppress oomycete fungi, and to overcome phosphorus deficiency;
- Amino acids to improve the energy balance of plants and soften temperature stress;
Boron as one of the key microelements, ensuring the health of vascular bundles and the formation of pollen grains for better pollination.
The optimal composition at present in all regions without exception is the tank mix ECOLINE Phosphite (K) 1.0–1.5 l/ha + ECOLINE Boron (Premium) 1.0 l/ha.
