The COBICO Laboratory has performed tests of treated seeds by Heubach method to the existing ESA - European Seed Association guidelines.
The Heubach's test has been used to determine the quality of treated seeds - says about the amount of a free dust released under certain conditions from the treated seeds.
The dust reference values that were developed by ESA are listed below:
- Corn: 0.75g of dust/ 100 000 seeds
- Oilseed rape: 0.50g of dust/ 700 000 seeds
- Sugar beet: 0.25g of dust/ 100 000 seed pellets
- Sunflower: 0.40g of dust/ 75 000 seeds
- Cereals: 4 g of dust/100 kg
- Carrot, witloof: 0.1 g of dust/100 000 seeds
- Onions: 0.2 g of dust/100 000 seeds
- Sweet corn: 0.75 g of dust/100 000 seeds
The dust reference values for the following crops are advisory as of July 1, 2019 and for one year. As of July 1, 2020 they will become normative.
- Green and seeded beans: 0.4 gr of dust/ 100 000 seeds
- Vegetable peas: 0.2 g of dust/100 000 seeds
In order to raise and confirm our competence, the Cobico Laboratory participates annually in international comparative research organized by FNPSMS / GERM-Services, achieving very good results.
Below are the certificates for the program carried out in 2018/2019 and 2017/2018
