8364. Schirman, R. and C.L. Canode. 1979. Direct seeding of annual field crops into bluegrass sod.. WSU Agr. Expt. Sta. Bull. XB 876, Pullman, WA.
Glyphosate (Roundup) was applied at rates of 1-1.5 lb/ac killed 85-90% of an established bluegrass stand and allowed direct seeding of winter wheat, spring wheat, peas, or lentils without any tillage. Burning of bluegrass residue increased vigor and yield of wheat but had inconsistent effects on legume yields. Success in killing the sod was dependent on active growth, which is influenced by weather and the varieties used. These factors should dictate the herbicide application date.
