Cercospora: How to Preserve Leaf Apparatus and Avoid Yield Loss?
Cercospora is one of the most widespread and underestimated fungal diseases that affects not only beets, but also soybeans, corn, grapes, and other cultures. It causes the appearance of characteristic dark spots with dry centers on leaves. And if not intervened in time - the leaves die, the ability to photosynthesis is lost, and the yield drops sharply.
In some regions, beet losses can reach up to 7.5 t/ha, and this is only official statistics. Cercospora is a cunning enemy, as it often "hides" behind other stresses, and it is not always noticed at early stages.
The peculiarity of the pathogen is its high ability to resist. This means that with each passing year, fungicide treatments become less effective, and the damage from the disease increases.
How to Act Effectively?
In the fight against Cercospora, a combination of fungicide with foliar fertilization has proven to be effective:
- ECOLINE Phosphite (K) - 1.0 l/ha
- ECOLINE Complex Magnesium (Chelates) - 1.0-1.5 l/ha
What Does This Give?
- Phosphorus in the form of phosphite has not only a nutrient, but also a fungistatic effect - it blocks the development of pathogens of the oomycete class, including Cercospora.
- Activates the synthesis of phytoalexins - natural protective compounds that strengthen plant immunity.
- No resistance to phosphites has been found - this is an important advantage in the season of frequent treatments.
- Magnesium in chelate form - a key element for maintaining photosynthesis and energy production, which is critical in conditions of damaged leaves.
The result - a working leaf apparatus, healthy plant development, and minimal yield losses.
