In this episode of the Iowa Ag Podcast, host David Geiger is joined by Renato Firmento, finance and operations manager with Spraytec, to discuss Iowa’s role in global agriculture and how international experience can strengthen farming in the Midwest. Renato shares his path from growing up in Brazil, to building a career in Iowa’s agricultural industry after moving to the U.S.
Renato explains Spraytec’s origins as a South American company founded by a farmer and how it has expanded into more than 40 countries. He breaks down what adjuvants are and why they matter, describing how they improve spray application by managing water quality, reducing drift, and ensuring products reach the plant effectively. In an environment where crop protection inputs are costly, Renato frames adjuvants as a tool that helps protect farmers’ investments.

The conversation highlights how South American farming expertise, particularly in pest and disease management, informs Spraytec’s approach in the U.S. Unlike the Midwest, many South American regions do not have winterkill, leading to more intensive spray programs and deep experience with application technology. Renato explains how that knowledge can translate to more consistent outcomes for U.S. farmers.
David and Renato also discuss why Iowa has become Spraytec’s U.S. base. Renato points to Iowa’s reputation, central location, and strong agricultural network as reasons international companies view the state as credible and welcoming. He describes how Spraytec regularly hosts farmers and agribusiness leaders from around the world, creating opportunities for learning, collaboration, and exchange.
