Seedstock Eligibility

  • Only turfgrass planting material approved by ACIA as eligible for certification may be entered into the certification program.
  • Source material shall maintain documented varietal identity throughout production.

Land Requirements

  • Fields must meet ACIA requirements for previous turfgrass production, volunteer turfgrass control, and field eligibility.

Field Inspection

  • Three official inspections are conducted annually: spring, summer, and fall.
  • Each inspection evaluates variety identity, off-type grasses, volunteer grasses, noxious and objectionable weeds, and overall field condition.

Isolation Requirements

Plantings of vegetatively propagated turfgrass must be isolated from other varieties and other perennial grasses by an artificial barrier and/or an isolation strip at least 6 feet wide to prevent mixing during the growing season and harvesting operation.
