Cover crops and catch crops

Chlorofiltre Blédor SAS FLY

Catch and cover crops

The Chlorofiltre Blédor SAS FLY catch crop is specifically designed for intercropping between two cereal crops. The brown mustard in this mixture helps to control certain soil-borne diseases such as take-off disease. Furthermore, this mixture is suitable for broadcast sowing under cover!

Benefits in detail

High summer biomass production between 2 winter wheats:
Thanks to the complementary action of vetches and brown mustard, biomass production is optimized.

Biofumigation:
The brown mustard VITTASSO is a late variety with a high glucosinolate (sinigrine) content. These glucosinolates have a reducing effect on takeall and fusarium.

Supports the biological activity of the soil:
MASSA and TITANE vetches are hardy varieties that are not very sensitive to pests (slugs, aphids,...) and they support the development of the brown mustard VITTASSO. Thanks to their low C/N ratio, there is a very good mineralization. 

Coating technology:
Cholorofiltre Blédor benefits from the new SAS FLY seed technology, thanks to which the seed can be sown in a classic way but also be broadcasted in the standing crop. This coating technology support the cover crops establishment even in limiting conditions and improves the ballistic effect for broadcasting the seeds evenely up to 24m width, depending on the equipment used (preferably a fertilizer spreader).
 

Seeds coating technologies

The Chlorofiltre BLEDOR cover crop benefits from the new SAS FLY seed technology.
Designed for broadcast-sown cover crops, this coating offers two innovative benefits:

SAS FLY optimises broadcast sowing up to 24 metres:
To ensure uniform sowing, the coating applied to the small seeds helps to standardise seed size and weight and improves trajectory during broadcast sowing.

  SAS FLY improves cover crop emergence in summer conditions:
The SAS FLY coating contains the biostimulant OSYR, which enhances the seeds’ drought stress tolerance and thus promotes cover crop establishment.

SAS FLY is a technology approved for use in organic farming (UAB).

2 techniques for sowing your SAS FLY cover crops

Recommended method: broadcast sowing before harvest

- Sowing the cover crops: between 1 and 15 days before the cereal harvest.
- Equipment: use a fertilizer spreader. Do not use a Delimbe-type spreader.
- Spreader settings: follow the manufacturers’ recommendations. SAS FLY cover crops are listed in the manufacturers’ application guides (Kuhn, Amazone, Sky, etc.). 
- Sowing rate: 20 kg/ha
- Stubble height: if broadcast sowing was carried out more than 10 days before harvest, do not mow too low, as this may damage the young seedlings. Optimal height: 20 cm.
- Straw management: opt for chopped and scattered straw to maintain soil moisture. If the straw is removed, increase the cover crop sowing rate by 20 to 30%.
- Pests: monitor for slugs.
- Note: some late-season sulfonylurea treatments may affect cover crop crop emergence.
- Tip: with early sowing, the cover crop may take some time to develop, so be patient!

Possible alternative technique: direct drilling after harvest

- Soil: manage crop residues promptly (if straw is removed).
- Sowing of cover crops: sow immediately after the cereal harvest, within 48 hours. 
- Equipment: prefer a direct-drilling seeder with tines rather than discs.
- Sowing rate: 20 kg/ha
- Rolling recommended to ensure seed-to-soil contact.
- Note: certain late-applied sulfonylurea treatments may affect the cover crop’s crop emergence.
- Tip: with early sowing, the cover crops may take some time to develop, so please be patient!
