Celebrating 25 Years
We are Certis Biologicals: Pioneers in Biological Crop Protection
With roots that trace back to the 1980’s and 1990’s, Certis Biologicals has long been the legacy leader of biological solutions for commercial agriculture and the home and garden markets. That leadership was cemented in 2001 when Thermo Trilogy was acquired by Mitsui & Co., one of the largest general trading companies in Japan.
Mitsui & Co. utilizes its unique business engineering capabilities to develop new business models aimed at solving challenges, generating new opportunities and improving existing business processes and portfolios to meet the market’s needs.
Bolstered by its new ownership and the power of the Mitsui & Co. brand, Certis Biologicals became the leader in innovation, manufacturing and marketing of bio-based solutions for both commercial agriculture and the home and garden markets.
Due to our continued growth, we are announcing our transition to Certis Biologicals, a global manufacturer and distributor of biological products that will meet the needs of partners and growers throughout the world.
In 2026, Certis Biologicals celebrates not only the anniversary of this milestone for us, but for the field of biologicals in general, which is experiencing a period of significant growth in markets both domestically and internationally.
With the largest portfolio of solutions for the management of pests, diseases, weeds and resistance issue, Certis Biologicals has the solutions that growers of all types need today. A pioneering pipeline of innovation means we also have solutions ready for the issues that growers will face tomorrow. Because we export and distribute those products in more than 50 countries around the world, Certis Biologicals can meet grower needs quickly.

Pioneering What’s Next
“The 25th anniversary celebration of Certis Biologicals represents thousands of ideas pursued, challenges overcome, and relationships built by people who saw the possibilities ahead and were motivated to achieve them.
I’m incredibly proud of the role we’ve played and continue to play in moving biological solutions forward in the crop protection and crop nutrition spaces, ultimately helping earn these tools a trusted place on farms around the world. That pioneering spirit is just as alive at Certis today as it was on our first day, and seeing it in action gives me great confidence in where we’re headed.
