Our Core Values

We always start with Safety

From the beginning we teamed entomology and plant pathology with chemical science to find safe effective solutions; today we work closely with EPA, USDA, State Departments of Pesticide Regulations, individual county ag commissioners, and our farmers and customers to make sure we preserve land, health, and the environment.

Innovation and R&D sets us apart

We register, defend, manufacture, package, distribute, and apply custom fumigant blends, specialized treatment applications, and other cutting edge growing solutions such as precision irrigation, fertigation, and plant-grafting.

Trust keeps us in business

Close personal relationships are the backbone of our company and how we do business; as a private family-owned company, we are in it for the long haul – success for our growers and customers means success for us.
