GROWMARK to Build New Ag Biologicals Plant in St.Louis, Missouri

December 23, 2025

GROWMARK announced today it will construct a state-of-the-art biological crop input manufacturing facility at the site of its St. Louis, Missouri-based AgraForm facility that produces and packages insecticides, fungicides, and biological products for agricultural use. GROWMARK acquired AgraForm in 2024.

The new biologicals plant will focus on manufacturing biological crop inputs for agricultural companies that either do not have their own production facilities or require additional access to production facilities. The plant will also be capable of manufacturing animal biological and waste treatment products.

Agricultural biologicals are crop inputs derived from living organisms or natural substances used to protect plants or enhance plant growth and soil health. They can be used in lieu of or alongside synthetic crop inputs and production products to support plant health, control pests, or improve nutrient efficiency. The St. Louis facility is expected to be operational in early 2027 and will produce biostimulants, biopesticides, and biofertilizers.

Global demand for biological manufacturing is also growing faster than the industry can supply, and although many companies have developed products, current manufacturing facility capacity has not kept pace.

“As demand for biological products continues to grow across the ag industry, the construction of the new manufacturing plant will allow GROWMARK to provide high-quality biological products, made in the United States, to stakeholders throughout North America,” said GROWMARK Executive Vice President and Chief Operating Officer Brad Drake. “It also allows GROWMARK to influence another critical point in the ag value chain to better serve its members and customers.”
