Velvetgrass, German or creeping (Holcus mollis)

EPTC (Eptam)

Rate 4 to 6 lb ai/a. Use 6-lb rate on finer soils or on heavy mats of roots and rhizomes.

Time Apply in spring or early fall on a thoroughly prepared seedbed.

Remarks A preplant soil-incorporated herbicide that also gives excellent results when metered into irrigation water. Effective if used in conjunction with a cropping program. Total kill requires at least 2 years. Prevent seedlings from reestablishing the stand. Suggested crop programs are:

  • Spray 4 to 6 lb/a in spring, and seed red clover or alfalfa on soil that has been limed and fertilized for best legume growth.
  • Spray 2 to 3 lb/a in spring; seed to corn for 2 years or follow with one of the other crops listed.
  • Spray 4 to 6 lb/a in fall and seed to crimson clover or fall flax. The subsequent crop should tolerate EPTC. Re-treat the second year.
  • Spray 4 lb/a in spring and summer fallow; follow by seeding to winter wheat or barley and treating with diuron to kill velvetgrass seedlings.

Caution Incorporate EPTC into soil 2 to 3 inches deep immediately after application. Use sprinkler irrigation to incorporate EPTC in very dry weather.
