Enhance Potato Crop Nutrition and Yield Potential with VIXERAN®
VIXERAN® is a biofertiliser containing nitrogen-fixing bacteria that colonise leaves, roots, and the rhizosphere, providing a natural source of nitrogen to improve crop nutrition and yield potential in potatoes. This is particularly beneficial as potatoes are nitrogen-hungry crops, consuming 60-80% of their total N-requirement between tuber initiation and tuber bulking, with nitrogen being crucial for leaf and tuber growth.
VIXERAN® contains the strain Azotobacter salinestris CECT 9690, a unique bacterium that offers significant agronomic benefits for potato cultivation.
Why should I use VIXERAN® in my potato crop?
Proven yield benefits
Increases marketable tuber numbers and overall yield, particularly when applied at tuber initiation. Validated through trials across a range of conditions with expert Syngenta R&D support.
Boosts nitrogen use & supply
Improves crop nitrogen use efficiency, providing a consistent, balanced nitrogen source. Forms a biofilm around roots, increasing nitrogen fixation surface area.
Versatile & robust colonisation
Survives both in and outside the plant, colonising leaves, roots, and rhizosphere. Effective even if foliar application is missed.
Demonstrated crop performance
Trials conducted under various conditions have shown that the application of VIXERAN® during tuber initiation can significantly enhance tuber yields. Its effectiveness has been validated across a range of environments and crops, and supported by Syngenta's expertise in formulation and application.

VIXERAN® growing success for potatoes
Optimal nitrogen management is crucial for potato cultivation. VIXERAN®, our foliar biofertiliser, provides a steady nitrogen supply throughout the season.
1. Ensure good coverage of both soil and leaf, with a focus on application during tuber initiation. A single application at tuber initiation, about 20 days after emergence, is most effective.
2. Apply 50 g/ha from planting to row closure, when daytime temperatures reach at least 10-12°C, with no frost 5 days before and after application.
3. VIXERAN® can be integrated with conventional agronomy programmes and is certified for organic production systems.
How to optimise the application of VIXERAN® in potatoes
VIXERAN® contains a living organism; therefore, this application advice is designed to support bacterial activity and a quick and effective colonisation.
| Product type | Biological foliar product, biofertiliser. Solid powder. |
| Dose | 50 g/ha. |
| Preparation | It is best practice to premix wettable powders. Add 1 sachet of VIXERAN® to min. 1.25L of water. Warmer water (+ 5°C) will make it solve quicker. VIXERAN® can be added directly to the induction hopper with the recommended volume of water if required, but ensure it is poured in gradually to avoid clumping. |
| Tank mix | VIXERAN® can be tank-mixed with other crop protection products for convenience, but check compatibility prior to use. When tank mixing, dilute other products with water first before adding the VIXERAN®. |
| Temperatures | To ensure successful colonisation, the crop should be actively growing. The ideal temperature is above 10-12°C. The minimum air temperature before and after application is 5°C. |
| Timing | The ideal timing is early crop stages. Covering both foliage and soil is preferable as the bacteria colonise leaves, roots and rhizosphere. Apply during the day when the plant’s stomata are open. Trials indicate that a single application at tuber initiation (perfect if stolons are starting to hook and swell) approximately 20 days after emergence is most effective. |
| Water volume | Use a water rate of 100-200 l/ha and a medium droplet size to ensure even distribution across foliage and soil. |
| Organic | Certified for use in organic production systems. Consult your certification body prior to use. |
| Additional information | Apply from crop emergence to row closure, with no frost for 5 days before and 5 days post application. |
