Varieties such as Crimson Seedless, Flame Seedless or Red Globe frequently do not reach sufficient colour development, and may be cause for rejection or loss of value.
There are many factors that influence the intensity of the colour of the vine berries, among them it is worth mentioning the light intensity, temperature, fruit load, leaf area, diseases due to viruses, nutrition, use of hormones and growth regulators, etc. (Kliewer, 1977).
Daymsa, the first European producer of leonardite and leader in the biostimulant and biocontrol sector has developed Madurel®, a nutritional intake tool that improves colour.
Results of applications in Red Globe and Crimson Seedless, showing the inducing effect of staining of Madurel® are shown in Figures 1 and 2.
The main benefits of Madurel® are:
- Maximises the colour of red varieties
- Homogenises maturity
- Increases sugar content
- Prevents the side effects of synthetic hormones: does not reduce the quality or condition of the berries and rachis.
- Free from residue, enabling application between harvests.
