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

PACK Symbio includes one of Lidea's 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 into the soil. They have a low frost tolerance, which makes them non-invasive for the main rapeseed crop.

This mix disrupts the insects in different ways. For example, in autumn, through the presence of companion plants which have a different appearance and a repulsive smell. Then in spring, through the presence of the pollen beetle trap ES ALICIA, which is the earliest rapeseed variety on the market. ES ALICIA has the specificity of flowering approximately 7 to 10 days before the other varieties, attracting pollen beetles and protecting the main hybrid. 

Second, weeds are reduced, due to the cover provided by the companion plants. The solution also improves the nitrogen in the soil by up to 30 units for rapeseed. And last but not least, the mix also improves the soil structure due to the cover, leading to less erosion as a result of the rooting of companion plants.

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

With its direct benefits and reduced expenses, the PACK Symbio offer improves the net rapeseed margin by up to €100/ha for farmers.


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, application of plant protection is necessary.

Management of companion plants: Sow at least 1 week earlier compared to standard WOSR sowing, then avoid fields with high weed pressure and avoid herbicides including clomazone or napropamid, in order to retain the cover!
