Heubach Method

Our 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 
• Green and seeded beans: 0.4 gr of dust/ 100 000 seeds
• Vegetable peas: 0.2 g of dust/100 000 seeds         
• Cotton: 6 g of dust/100 kg. The value will be advisory for the time being. It will become normative on July 1, 2023.
