Presentation from February 2007

Terry Hollifield, executive director of Georgia Crop Improvement Association

Why Was ITGAP Created?

Maintain identity of turfgrass varieties

  • University of Georgia varieties
  • Privately released varieties

Establish production protocols to assure purity and quality

  • contamination
  • other crop
  • weeds

Past Experience

  • Tifway
  • Tifdwarf

There are a large number of turfgrass cultivars available to the industry.

More opportunity for misidentification of varieties

  • More opportunity for contamination of varieties

Modern day turfgrass varieties are chosen and planted for specific characteristics that they possess.

Desirable characteristics

  • Density
  • Temperature tolerances + –
  • Susceptibility to chemical injury
  • Traffic tolerance
  • Spring emergence
  • Mowing frequency
  • Disease and insect resistance
  • Uniformity
  • Etc.

Contamination = Nonuniformity

Compromises desirable characteristics

  • Color
  • Cold tolerance
  • Chemical injury
  • Traffic tolerance
  • Rate of growth
  • Spring emergence
  • Salt tolerance
  • Disease & insect resistance

Why Do You “The Producer” Need To Be In ITGAP?

  • Access to newer varieties
  • Marketing
    • Expectations of developers
    • Product Quality
    • Repeat customers
  • Allows you to elevate your farm above the rest
    • Quality management system
    • Third party inspections
    • Promote varietal purity

ITGAP Protocols

Application for membership and inspection To:

Georgia Crop Improvement Association
2425 South Milledge Ave
Athens, GA 30605

Land Requirements

  • Production fields must be inspected prior to planting
    • Free of contaminating other species
    • Fields prone to flooding not acceptable
    • Wind/traffic barriers may be required

Dedicated Equipment

  • Mowing equipment must be dedicated for each variety produced under the ITGAP program.
  • Non-dedicated equipment (tractors, fertilizer equipment, spray equipment) must be thoroughly washed prior to entering ITGAP fields.
    • Wash facilities must be available for cleaning equipment.
    • At no time should non dedicated equipment (mowers, harvesters, tractors) be allowed to travel from non program fields across ITGAP fields
    • Barriers may be required. why????
  • Wheeled (center pivot) irrigation systems must travel on program fields of the same variety only.
  • Irrigation equipment that is mobile must be dedicated and not moved from field. why????

Field Requirements

  • Isolation from any other varieties
    • 20 meters if source of possible contamination produces seed or pollen
    • 3 meters from non-seed or pollen producing varieties
      • Bare land
      • Artificial barrier

Planting Stock

  • Sources must be approved prior to planting
  • ITGAP must have documentation of planting stock:
    • Producer
    • Date of harvest
    • Kind and variety
    • Quantity

Expansion of Fields

  • Foundation planting material when establishing a farm nursery will be planted on fumigated land.
  • Fumigation material and rates to be approved by ITGAP Administrator

Life of Production Field

  • Five year limit
    • Fields can be extended beyond five years upon successful completion of intensive inspections
    • ITGAP may require grow out test, DNA test, etc.

Field Inspections

  • Fields must be inspected annually by an ITGAP representative
  • Quarterly inspections by producer is required and must be documented
  • Fields must be grown using good practices
    • Adequate water
    • Fertility
    • Pest control
    • Mowing

Field Standards

  • Annual or quarterly inspections
    • Maximum of an average of 3 plants of another variety per ha.
      • Bermuda in Paspalum
      • Zoysia in Bermuda
      • ETC.


Fields exceeding an average of 3 plants per Ha of another variety must be reinspected

Certificates of Assurance

  • ITGAP certificates will accompany each shipment of grass.
  • Available from program administrator
  • The certificate will display:
    • Kind and variety
    • Quantity shipped
    • Field number
    • Date of harvest
