Now is the time to inspect CRP fields for the presence of sericea lespedeza. Early detection is essential to economical control.
Sericea lespedeza is a perennial with erect stems up to 5 ft. tall. The leaves, with 3 leaflets are less than 1 inch to 1 1/2 inches long and 1/4 to 1/2 inch wide. Flowering occurs from mid or late July to October and may be tinged with purple but always dry to yellow.
Sericea lespedeza reproduces primarily by seed. Seeds move with water, infested hay, birds, and wildlife. The hard seed passes through the digestive tract of animals.
Mowing in the late bud stage from mid-July to late summer should reduce the vigor of the infestation. The use of a sickle mower is preferred.
Remedy at 1 to 2 pints per acre.
Escort at 1/2 to 1 ounce per acre.
The use of a polymer type deposition aid may enhance control.
Thorough coverage is essential for good control.
Both herbicides are available at the Pratt County Weed Department on a cost share basis.
