1. Does it work by soaking in vine nursery ?

Just out of stratification: Osiryl is applied during the seedling raising period, as soon as roots start coming out over the 2 to 3 months of cultivation.

2. Does it work by soaking seedlings for market produce before planting ( combined with previcur for instance) ?

We’ll answer as previously. Osiryl is used when seedlings restart and roots are in their absorbing phase. On the other hand, results are particularly effective with potted vine plants by over soaking or watering the mini-lump substrate with a 0.2% solution.

3. Can it flow through watering systems, dusters, spray and drip systems ?

Approved for use within and off soil, OSIRYL doesn’t block up or precipitate, so there’s no problem when it’s been well mixed with water in accordance with the concentrations recommended in the product data sheet. This has been confirmed, unlike certain products based on humic acids (pH: 12-14) that can block up.

4. Is it possible to use it off soil in a solution of nitric acid to lower pH ?

Osiryl is compatible within a wide pH spectrum; its low acidic nature is well suited to the optimal absorption which stands around pH6, off soil.

5. Is there any risk of impairing canopy in case of splashing ?

Osiryl is applied by sprinkling (at 2%) especially on lettuce (very fragile leaves) without any problem. When sprayed over soil, 200 to 500L/ha on vine no phyto problem will occur due to splashing over canopy.

6. How useful on compact soil (hydromorphic, tight, superficial soils) ?

Osiryl is particularly well-suited to that type of condition where organic matter will be recommended to improve soil and Osiryl is used to restart the root system and better colonize soil.

7. Do you recommend applying Osiryl before or after tillage in spring ?

The ideal time is to apply when roots are in absorbing situation or before vine bud burst (see question about application calendar). It is thus recommended to apply as close as possible to the root absorption threshold and beyond. There's no point in applying on vine in summer.

8. What are the risks of leaching after heavy rainfall ?

Osiryl is organic with limited leaching within balanced textured soils; however risks are high with very porous soils poor in MO. You should opt to apply on vine during root activity period (from bud burst) on this type of soil and fractioning is possible with market gardening.

9. Can Osiryl be referenced on the ACTAA list ?

Osiryl is not supposed to be a product for protecting crops- it cannot appear on the ACTA list.

10. How deep within soil should it be applied by coulter /cutter or stake ?

Osiryl is applied over upper horizons (10 to 30cm) and the more you go into the season the more you will get close to a chelated type option.

11. Is it compatible with chelates ?

Yes it is and even better as it maximizes root absorption, therefore better efficiency of chelates.

12. Is it compatible with weed killers ?

It is, as long as the 200 to 500L/ha application water volumes are respected ( for low volumes have a classic test of physical compatibility in a bucket).

13. At what temperature can it be used ?

The best application time is the threshold of bud burst in spring ( >10°C within soil for vine) that marks the limit above which roots are about to restart. So Osiryl is absorbed as soon as roots restart; if applied earlier Osiryl fixes on soil colloids in the expectancy of plant awakening.

14. In what season can it be applied in open field ?

The best time is spring and autumn before cold spells for autumn planting – no point in applying to vines in summer. However, for market gardening, Osiryl is applied throughout the cycle so as to restore reserves (asparagus…), in regressive situation or root restart (melon …), and for crop homogeneity and quality.

15. Is it efficient by foliar application when one knows vine roots can go deeper than 3m within soil ?

Vine can indeed grow down deeper than >10m; in that case it is quite an exceptional situation for hydric needs. Generally, vine feeds within the 20 to 50cm upper layers of soil, hence the principle of surface fertilization. Osiryl obeys this rule and will be conveyed to roots by water in the same way.

16. Does it make grass grow ?

Osiryl is not a fertilizer but a root development stimulator. Grass growth is controlled by supplying nitrogenous fertilizers which is the key factor, so there is no consequence. However, on lawns suffering from deficiencies despite nitrogenous manuring, Osiryl promotes the restart of roots in stressful situation.

17. How long is it active within soil ?

Osiryl is readily available if given properly by the roots sphere, otherwise just like any organic molecule it fixes on the soil colloids available to the plant. According to our experiments, its effect can be noticed 3 months following application after planting in vineyard. In fact the plant reacts rapidly, hence the incidence on the root system that is noticed several months later and especially during stressful situations in summer. For intensive farming however, Osiryl is rapidly metabolised as high needs require fractioning applications in the same principle as for legume crop nutrition.

18. Does it work with any soil type ?

Yes it does, the mechanism of protection by auxins does not depend on the soil physico-chemical conditions since the product is absorbed by roots. One must remember not to wash down the product by watering too heavily. It is advisable the product should be applied timely so as to optimize its efficiency (see previous questions).

19. Can OSIRYL be used on cuttings ?

Yes, the tests carried out on quince trees show significant improvement on the cuttings root restart, so cuttings should be watered in this case with a 2% solution of Osiryl and the application renewed 15 days later.

20. Is it recommended to plan applications of OSIRYL on perennials much later in autumn ?

Yes indeed, ligneous plants raised in nurseries and open field show 2 optimal periods of nutritional absorption: as soon as they're planted or, for adult plants when young radicles start developing in spring and early autumn by the intake and storage of nutrients before the first cold spells.

21. Relying on OSIRYL results on root resistance, is it possible to improve the nutrition of crops in stressful situation ?

Yes it is, the observations carried out on root systems in stressful situations due to necrosis … show that treatment with Osiryl allows to better feed the plants presenting symptoms of root deficiencies. In that case, the treatment for these symptoms must be complemented with supplies of nutritional and hydric elements.
