History
● Pests are always adapting to new environments and growing conditions change constantly.
● Before seed treatments were available, growers were soaking their seeds in chlorine or manure in large amounts. Sometimes growers would turn to arsenic- and mercury-based compounds due to a lack of options.
● Seed treatments represent extremely efficient and targeted delivery systems for pesticides; only a small amount of a pesticide is applied to the seed before planting, which allows for reduced applications and exposure potential.

Quality and safety of treated seed
Stepwise Improvements
• Improvement of formulations and
recipes
• Implementation of approved recipes
• Implementation of stewardship
programs
• Initiating research on novel polymers
• Research in improvements of
application technologies
• Continued improvement and
education of seed handling from
harvest to planting
• Continued research and
development on novel polymers
• Research in improvements of
application technologies
• New delivery systems for Seed
Applied Technologies
• Continued research and collaboration
with industry partners –equipment
manufactures, seed trade, and
polymer technology providers
…is a shared responsibility along the supply chain
…is continuously on the agenda of improvement of seed applied technologies

Dust Assessment - according to SOP of ESTA
11
Dust assessment on simulated planter level
Principle
• Collection of dust at exit of planting unit on filter
• Assessment of total dust-off on filter
• Calculation of dust-off per seed unit or acre/ha

Recipes with different polymers and rates
AVERAGE of 2 replicates per 100 000 seeds
Polymers play a key role in dust reduction and recipe development Example: P21 was rejected due to outright unacceptable dust levels
14
Recipe screening based on novel polymers PICTOS assessment
Selection of the appropriate polymer is critical; weak polymers do not stick to the seed (TRT 1- 6; 10 - 11); strong polymers reduce the dust-off impressively while maintaining germination

Summary and conclusions
• The quality of treated seed is a multifactorial result
• Seed cleaning is a first crucial step in ensuring quality seed treatment
• Great improvements have been made on polymers and recipes (products + polymers)
• Polymers and recipes are critical in managing potential dust-off and abrasion
• Effective quality management and stewardship along supply chain is a must
• Research and development on-going into novel polymers and application processes
