Biostimulants for potatoes
Strength against stress with boncrop flow
Potatoes are a valuable yet demanding crop.
boncrop flow supports potato growth in many different ways. It starts with the root growth and even encourages a higher photosynthetic performance and better tolerance to stress.
From the field: A visible difference under drought stress
A comparison of two Bernina potato plants demonstrates how boncrop flow can work under real-world conditions. The plant treated with boncrop flow (right) yielded 310 g more tubers than the untreated control plant (left). The difference in tuber set becomes particularly evident following hot weeks with little rainfall.
Advantages of boncrop flow in potatoes and your benefit
Advantages
|
Benefits |
|---|---|
| Strong root growth | Higher water and nutrient uptake lead to a better root system with high yields at the same time |
| Greater stress tolerance and higher photosynthetic performance | Better drought stress tolerance, easier irrigation management and higher starch production |
| More efficient metabolism | Increased plant vitality for uniform growth |
| Homogeneous crops | More uniform growth and improved harvest quality |
| Better sorting | Higher proportion of marketable goods and optimised marketing |
Controlled trials 2022-2024 – Stable yields and better sorting for potatoes
Between 2022 and 2024, extensive trials on the use of boncrop flow in potatoes were conducted at several precision trial sites in Huntlosen (Lower Saxony). Different types of varieties were examined – chips and French fry potatoes as well as table potatoes – with consistently clear and meaningful results.
More marketable tubers:
Across all years and varieties, there was a clear shift in tuber sizes in favor of the marketing-relevant fractions. In particular, the proportion of larger tubers increased significantly (up to +24%), while the proportion of small tubers under 35 mm was reduced, in some cases significantly (up to –31%). This improves sorting and increases the economically usable yield.
Higher total yield:
Boncrop flow also consistently achieved better results than the untreated control in terms of total tuber yield. Depending on the year and variety, the additional yields ranged between +3% and +8%. This confirms the positive effect of boncrop flow regardless of variety and growing year.
The precision trials conducted between 2022 and 2024 clearly demonstrate that boncrop flow not only increases the total yield, but above all improves the tuber structure and market quality of the potatoes. This is a clear advantage for farms that rely on high revenues, better sorting, and stable performance over many years.
Perfect timing and quantity
We recommend splitting the application of boncrop flow in the potato:
- Recommended application rate: 2 treatments of 2 litres/ha each
- 1st treatment with 2 litres/ha from BBCH 30-40 at the beginning of the hook stage (usually shortly before row closure). Optimum assurance of vitality, photosynthetic performance and yield formation of the potato, even under stress.
- 2nd treatment with 2 litres/ha after 7 to 21 days (adapted to the plant protection measures on the farm).
- No additional pass necessary, as boncrop flow can generally be combined well with the usual plant protection measures.
