Who We Are

Adjuvants Plus Inc. is a Canadian-based, agri-business that develops innovative solutions to improve field and horticultural crop yields. In addition to a growing portfolio of crop protection products, Adjuvants Plus has a natural biological business technology interest. Adjuvants Plus is a diversified company with a solid, base business and is positioned for growth from a promising pipeline of new products.

Adjuvants Plus Inc. was built on the premise that innovation with existing chemistry would open up new avenues in the crop protection industry by creating added value for growers. Product innovation can be measured in a number of ways, one of which is whether these inventions are patentable.

Our Milestones

Adjuvants Plus is a privately held Canadian corporation established in 2000. The company was founded by Dr. William Brown and James Stewart. As a result of Bill and Jim’s tenacity, their experience in agri-business and their network within the agricultural research community, the Adjuvants Plus Inc. platform was established. Sadly, after a courageous fight with cancer, Jim passed away in 2012. Continuing to build this business legacy, Bill, in conjunction with a strong management team, is growing the organization with new products and technology acquisitions.
