Reducing seed treatment dust in the field

The dust trap

Seed treatment products protect crops like rapeseed or corn from fungal diseases and insect pests. However, if particles of the protective layer which contain an insecticidal active substance are rubbed off the seed, they have the potential to harm honey bees, wild bees and other beneficials. Bayer researchers are working on making the entire seed treatment process even safer for beneficial insects and the environment.

// Seed treatment is crucial for agriculture.

// Unwanted dust can accompany treated seeds.

// Bayer researchers are working on ways to prevent this dust.

// Less dust means less potential risk for pollinators.

The right approach

Karl-Hans Wellen is a sub-contractor providing agricultural services. He testet the SweepAir prototype on his clients’ fields.

How did SweepAir perform in practice?

Sowing conditions were very dusty and dry here in 2014 – really hard on the equipment. It should be clear that we were testing a prototype. It still has a few glitches; for example, the equipment occasionally clogged. However, these things will be taken care of as the equipment is improved.

How did your customers respond to the prototype?

Farmers are very environmentally conscious, and the SweepAir technology is a good approach to making agriculture more ecologically sound. Our customers with whom we tested the system were, therefore, very interested.
