Grower Selection

Syngenta has developed a set of grower criteria based on stewardship requirements for growing and handling Enogen corn. The ethanol plant selects and directly contracts with growers that meet the required criteria.

Enogen Technology License

Enogen technology will be delivered only to growers who sign both a technology license with Syngenta and a corn production contract with an Enogen licensed ethanol plant.

Corn Production Contract

The Enogen Corn Production Contract specifies the acres to be planted, stewardship, grain products and delivery requirements, incentive on the grain produced, etc. All Enogen grain must be segregated and stored in dedicated storage bins.

Planting Operation

Growers are required to identify Enogen™ planted fields and segregated storage bin sites by recording GPS coordinates or field IDs. Border rows of corn or spatial isolation from neighboring corn fields is also required. When planting is complete, growers need to adequately clean the planter before planting the next field.

Reporting

After planting, Enogen growers submit a report to Syngenta via the electronic Enogen grain contract management system confirming planting details. During the growing season, growers scout Enogen corn fields and report crop/field condition and any issues. At the dent corn stage yield checks must be taken from the fields to estimate Enogen grain production.

Harvest

Yield data (harvested bushels, moisture and test weight) are reported via the electronic contract management system. Border rows are harvested and mixed with Enogen grain. After harvest, growers are required to clean the combine and all related equipment (e.g. dryer, conveyors, etc.) used for Enogen grain.

Delivery &Tracking of Enogen Grain

When Enogen grain is delivered to the ethanol plant, the ethanol plant staff matches the scale ticket to the production contract ID, the storage bin, and the field that produced the Enogen grain.

Quality Assurance & Audits

Each load of Enogen grain is tested at the ethanol plant for enzyme expression using a quality testing tool. The test typically takes three to four minutes to complete.
