Abstract/Contents:In 1970 trials, herbicides were applied to newly planted plugs of Emerald zoysia [Zoysia japonica X Z. tenuifolia], Meyer zoysia [Z. japonica] and 8 strains of Cynodon dactylon. Bensulide at 15 lb/acre caused temporary yellow coloration of Meyer and Emerald zoysia and slight discoloration of C. dactylon. Simazine at 3 lb/acre inhibited stolon development in Emerald zoysia and caused moderate injury to C. dactylon. Siduron at 12 lb/acre was safe for zoysia but caused moderate to severe injury to C. dactylon. Benfluralin at 1.5 lb/acre reduced the number of stolons of Meyer zoysia while DCPA (chlorthal-dimethyl) was tolerated well by all the grasses. A follow-up treatment consisting of 2,4-D at 1 lb + dicamba at 1.6 lb/acre 3 weeks later resulted in a 45% increase in the number of stolons/plug for both zoysias but caused a 5% reduction in cover of C. dactylon. Poor recovery of turfgrasses after the following winter may have been due to herbicide damage to roots.
