It is a big challenge to reach the highest quality in seed treatment possible due to the influence of climatic conditions, available technology, and the crops variety. Modern coating technology helps to optimize seed treatment. However, they need to be well designed to meet the specific requirements.

In Brief:

  • Film coatings nowadays have more functions than simple dust reduction
  • For the treatment of corn, Bayer offers film coatings that prevent abrasion even if the seeds are exposed to exceptionally rough handling and treated under very cold temperatures
  • Bayer developed Fluency Agent for the North American market which reduces dust remarkably
Developing the right treatment recipe and getting the best possible treatment quality can be very challenging for seed treaters. Especially, as the seed treatment recipes are getting more complex and numerous, products like chemical and biological crop protection, micronutrients, and film coating are added to meet customers’ needs. Bayer SeedGrowth™ supports those treaters by developing coating solutions that go beyond pure technical benefits such as dust reduction, flowability improvement, and enhancement of the visual appearance of the treated seeds. “Some of our coatings also contain micronutrients that have a boosting effect on the early plant development to make sure that the plant has the best conditions to develop in the first growing stages,” says Robert Puhl, Marketing and Sales Manager Bayer SeedGrowth Coatings. “Bringing together different benefits in one product makes the application process less complex for treaters.”

Local habits in mind

This year, the Peridiam™ Ferti range will be expanded by a coating that can be used for soybean seeds. In this particular case, the micronutrient molybdenum will be part of the coatings formulation. Molybdenum is a micronutrient that plays a vital role in the nitrogen transformation and uptake in the soybean plant. “Before launching the product, we made sure that our film coating is compatible not only with the commonly used Bayer SeedGrowth products, but also with cobalt for example, since we know that in some areas cobalt is an important component in our customers’ treatment recipes,” says Puhl.

Adding micronutrients in film coatings has already been a successful concept for Bayer. In Poland and France, for instance, Peridiam Ferti for cereals is offered in combination with Bayer SeedGrowth products. “By adding our Peridiam to the treatment recipe, the treatment quality is brought to a much higher level,” highlights Puhl. The crop protection product that is put on the seed adheres well to it. Apart from the other positive feature of film coatings, the growers especially benefit from more resistant plants. This is important, as winter cereals, for example, are sown during fall and need to become strong plants as soon as possible to best survive the cold temperatures during winter time.

China: low treating temperatures

When developing a new product not only the climatic conditions have to be considered, there are different types of application and treatment technology, as well. “In China, for example, we were looking at the treatment of corn, where – due to the treatment process – the seeds are exposed to an unusually high level of mechanical stress and abrasion during the treatment and packaging process,” says Puhl. As the seeds are sown in spring, they need to be treated during winter, which is characterized by very low temperatures in the main corn growing regions. Therefore, the seeds may even be frozen when they are put into the treater. “To answer our Chinese customers’ needs, we developed a new Peridiam Coating for corn where the adhesion properties – even under these difficult conditions – are in focus,” says Puhl. “At the same time flowability is guaranteed.”

Reduced seed-to-seed friction

For the North American market, Bayer has developed a new planter seed lubricant for corn, soybeans, and sugar beets. Lubricants help reduce friction and improve uniformity of planting. In lab tests, Fluency Agent was shown to reduce the amount of total dust released in treated seeds by 90 % versus talc and 60 % versus graphite. To minimize dust from treated seeds and taking precautions to plant those seeds properly, growers in Canada are required by law to use Bayer’s Fluency Agent for neonicotinoid-treated corn and soybean seeds. A grower survey has shown that users were satisfied with Fluency Agent: 90 % of the interviewees said that the product is better than or equal to their current lubricant. “The film coatings product development is very specific. A product that we developed for soy beans might not be working very well for cereals,” explains Puhl. “Therefore, we are very precise with the development of our own film coatings so that we can be sure to deliver the best possible quality.”

ACCELERATED EVOLUTION

The first Peridiam product was launched in 1987. It was a colorless formulation that was focused on dust reduction in cereals. Since then the product range experienced an accelerated evolution: Today, dust reduction, flowability, even coverage, and coloration are the basic technical requirements for a good coating. By adding micronutrients into the coatings formulation, as they can be found in coatings of the Peridiam Ferti range, Bayer offers their customers additional benefits: a possible reduction of the complexity of the treatment process as well as the support of early plant development.
