Seeds coated with various Bayer SeedGrowth film coatings

Bayer SeedGrowth™ Coatings can point to decades of leading-edge experience and outstanding expertise in seed-applied technologies – film coatings, fluency powders, drying powders, pelleting processes, and the like. With a dedicated facility and team based at Méréville, France, Bayer SeedGrowth Coatings is much more than a mere production unit. Our full-blown R&D team develops new and innovative seed-applied technologies and tackles the challenges of germination, sowability, flowability and dust control both in the lab and on the field. Agronomic evaluations are carried out to test flowability, sowability and field emergence, and when all the tests have been completed, the in-house Heubach dust meter is used to analyze dust emissions. What’s more, since all the seed-applied technologies are manufactured to the highest possible standards at Méréville, growers all over the world can be sure of uniformly high quality from Bayer.

Integral part of Bayer SeedGrowth

As an integral part of the comprehensive and fully integrated system for on-seed applications that is Bayer SeedGrowth, our coatings specialists enjoy unrestricted access to the Bayer SeedGrowth product pipeline. As a result, they develop coatings that are entirely compatible with our new and innovative seed treatment products. At the same time, Bayer’s inoculants and biologics know-how is opening up new research pipelines that will also help to make good seeds perform even better. Whatever the product, the high quality standards for which Bayer is renowned always apply at Bayer SeedGrowth Coatings. So wherever in the world farmers use these seeds, they benefit from the uniformly high quality of film coatings from Bayer.

Ensuring highest quality standards

Marc Andrieux, the Head of SeedGrowth Coatings explains how such high quality standards are maintained: “None of our film coatings leaves our facility without our quality control team giving its permission. These people ensure compliance with the highest quality standards. Everyone at Méréville is working to ensure that the seeds perform best. And this is possible because our film coatings deliver excellent coverage on every single seed – no uneven distribution of the active ingredients on the seed, and no gaps in the protective shield around the seed. We’re protecting the investment a farmer has made in his seed. What we want is for each film-coated seed to grow into a strong and healthy plant, thriving to its full genetic potential.”

Reducing dust emissions by up to 95%

Bernard de Vergnes, the R&D Manager at Méréville, leads a full-blown R&D team dedicated to the development of new and better film coatings: “One of the focal points of our research is dust control.” To measure dust emissions Bernard’s team uses the internationally established Heubach test, which even detects the finest particles that are most sensitive to drift. “Tests show that coated seeds contain a lot less dust than seeds without a Peridiam film coating,” Bernard says. “We can reduce emissions by up to 95% so everyone involved in seed treatment is better protected, and the active ingredients stay on the seed.”

Maximizing flowability and plantability

Greg Ginisty, the Business Development Manager at Méréville, is keen to point out that Bernard’s team are also good at enhancing seed qualities: “Our people maximize flowability, i.e. the ability of a seed to pass through an application machine easily without any sticking or caking. We can actually measure the fact that our coatings significantly improve flowability.” Bernard explains how: “We perform computer-assisted flowability tests to improve this quality in our new film coatings. Good flowability can save time during application and improve accuracy during planting. That’s why we also check what happens to our coatings under real field conditions by simulating pneumatic or mechanical seed drilling. That way, we ensure our Peridiam coatings portfolio covers the wide range of local sowing practices all over the world.”

Distinctively smart colors

The rich variety of seed colors may look like a marketing gimmick but is actually a very down-to-earth benefit, as Greg explains: “Color is the most obvious attribute to distinguish one thing from another – and a treated from a non-treated seed. But we also use colors because they allow a seed to be unmistakably associated with its distinctive attributes. Peridiam Evolution, for example, has a shiny surface finish that says everything about the high value underneath, which deserves the very best shield.”

How you benefit of from our coatings

  • Uniform seed treatment application for optimum coverage
  • Improved adhesion and coverage so all beneficial additives stay on the seed
  • Protection of operators and beneficials from dust with emissions reduced by up to 95% – for more dust-off information see Services
  • Branding and visual differentiation through coloring
  • Improved flowability in the planting equipment and sowability on the farm
  • Micronutrients to promote plant growth

Why our R&D makes a difference

The research and development work undertaken by Bayer SeedGrowth Coatings builds on decades of experience and expertise in seed-applied technologies. The unit’s innovative record speaks for itself. The 14-strong R&D team enjoys comprehensive lab facilities at Méréville in France, from where coatings are developed for applications all over the world. Tests are carried out to ensure the suitability of coatings for applications ranging from sub-Saharan heat to Siberian cold, and from the dry plains of the US Midwest to the humid tropics of Brazil. “With the Bayer research pipelines right at our fingertips, we have a head start when it comes to developing film coatings to match new insecticidal or fungicidal compounds,” says Marc Andrieux, Head of SeedGrowth Coatings.

Additional research pipeline in biologics

A whole new chapter in the development of new seed-applied technologies has opened up through Bayer’s acquisition of the biological companies AgraQuest and Prophyta. Bernard de Vergnes, Research and Development Manager at Bayer SeedGrowth Coatings, explains the significance of these acquisitions: “This new line of business gives our coatings R&D team access to an additional research pipeline with new exciting technologies to make good seed perform even better.”

Peridiam – a truly global brand

In line with the global scope of Bayer SeedGrowth, its global film coating brand, Peridiam, offers solutions for virtually all crops, e.g. corn, cotton, canola, cereals, rice, sunflower, vegetables, soybean and pasture. By offering different coating solutions tailored to differing market needs, Peridiam meets the demands made on a truly global brand from an innovation-driven coatings company. As Greg Ginisty, Business Development Manager, Bayer SeedGrowth Coatings, points out, “We are based in France, but our offering has the whole world in mind. We have a global spread.”

Peridiam Ferti – promoting plant health

Collaboration with Bayer plant health specialists recently led to the development of a significant enhancement to the Peridiam range, the plant health promoter Peridiam Ferti. “This is a coating that contains micronutrients dosed to correspond to the needs of the crops,” says Bernard de Vergnes, Research and Development Manager at Bayer SeedGrowth Coatings. “Adding zinc and boron gives corn or cotton seedlings a jump-start in life, while cereals profit from manganese, zinc and molybdenum.” Summing up the benefits of the new product, he adds: “Peridiam Ferti puts the micronutrients where and when plants need them most: around the seed and when the seed develops.”

Coatings have to be registered in some countries. Please check with your local supplier for availability.
