(Eragrostis intermedia)
GENERAL STANDARDS -- The standards on this sheet are in part condensed and apply to Eragrostis intermedia. For greater detail and additional provisions, see the Native Seed Program Standards.
APPLICATION -- Applications should be submitted electronically on CCIA’s website (Application to grow and certify seed) as soon as possible and no later than three (3) weeks after planting. New applicants should contact the CCIA office for instructions on obtaining access to the online application system.
FIELD HISTORY -- Land must not have grown or been seeded to any Eragrostis species during previous 3 years to be eligible to produce G1 seed, 2 years to produce G2 seed, and 1 year to produce G3-GX seed. The seed crop must be planted in distinct rows. Exceptions must be approved by the Seed Certification Office prior to planting.
ISOLATION -- Fields or portions of fields producing seed must be isolated the following distances:
| Factor | G1 | G2 | G3 | G4-GX |
| <5 acres | 900’ | 450’ | 330’ | 165’ |
| ≥5 acres | 600’ | 300’ | 165’ | 165’ |
FIELD INSPECTION -- Include a seedling and a seed crop inspection.
Off-Types -- Every field should be rogued to remove any plants of another crop or variety, including volunteers. Native seed selections cannot always be differentiated at field inspection. When differences can be distinguished, the maximum mixture of other varieties, off-types, established volunteers, and inseparable other species or crops may not exceed:
| G1 | G2 to GX | |
| 1:1,000 | 1:500 | |
Weeds -- Fields must be free of any noxious weeds with a prohibited seed rating. Noxious weeds with a Restricted seed rating and common weeds difficult to separate must be controlled. Prohibited and Restricted noxious weeds are listed in the California Seed Law/CA Code of Regulations/Sections 3854 and 3855. See California Seed Law - Prohibited and Restricted Noxious Weed List.
Fields may be refused certification due to unsatisfactory appearance caused by weeds, poor growth, poor stand, disease, insect damage, and any other condition which prevents accurate inspection or creates doubt as to identity of the variety.
