The benchmark in rootstock!

- A very homogeneous rootstock. Suitable for both tomatoes and eggplants.
- Excellent fast and homogeneous germination. (+/- 95% germination rate).
- Can be sown the same day as scions. (for eggplants sow 8 to 10 days before PG).
- Rather generative rootstock promoting flowering therefore production.
- High Resistance (HR): ToMV: 0-2,
- Intermediate Resistor(IR); Pl / Ma, Mi, Mj.
- Seeds not coated or treated.

Grafting is particularly recommended to increase productivity and resistance, but becomes essential when crop rotation is impossible and the soil is infested with nematodes (greenhouse cultivation etc...)!

Arnold vs Fortamino
Arnold is more "generative" oriented (flowering and fruiting) then that Fortamino is more of a compromise (vegetative at the beginning of the season, generative afterwards).
Fortamino's resistances are stronger than Arnold's for number of diseases except against nematodes where they are equivalent.
