PACK SYMBIO solution is a ready-to-use blend that combines two elite rapeseed varieties associated with companion plants. 

We add to the PACK Symbio one of our elite high-yielding varieties with very good agronomic behaviour. 

This blend is made with Fenugreek and Ervil vetch. They belong to the Fabaceae family (legume), which form a symbiotic association with some species of bacteria (rhizobium spp…). This symbiosis gives Fabaceae the unique ability among field crop species to fix nitrogen from the air and feed on it, and then release it to the soil. They have a low frost tolerance, which makes them non-invasive for the main rapeseed crop.

This mix allows to disrupt the insects in different ways. For example, in autumn, because of the presence of the companion plants which have a different aspect and a repulsive smell. Then later on, in spring, by the presence of the pollen beetle's trap ES ALICIA, which is the earliest rapeseed variety on the market. It has the particularity of flowering about 7 to 10 days before the other varieties to attract pollen beetles and protect the main hybrid. 

Second, we are noticing a reduction in weeds, thanks to the cover by the companion plants on the soil. The solution also improves the nitrogen in the soil by up to 30 units for rapeseed. And last but not least, this mix also improves the soil structure through the cover, leading to less erosion because of the rooting of the companion plants.

PACK SYMBIO innovation can be used with classical seed drills. This innovation improves the sustainability of your rapeseed crop while securing your yields and making your work easier.

Through its direct benefits and expense reductions, the PACK Symbio offer improves the net rapeseed margin by up to €100/ha for farmers.


Some advice for the management of rapeseed: ES ALICIA at 7% (3pl./1m2) is efficient in situations of low to medium pressure. Be careful to be under the threshold of 5 to 7 pollen beetles per plant on the main variety. Otherwise, an application is necessary.

Some advice for the management of the companion plants: make sure you sow, at least 1 week earlier compared to classical WOSR sowing, then avoid fields with a high weed pressure and don’t use herbicides including clomazone or napropamid, in order to keep the cover!
