Annual bluegrass control with herbicides in cool-season turfgrasses

  1. A.J. Turgeon

Abstract

A literature review of herbicide studies on the control of annual bluegrass (Poa annua L.) is presented with emphasis on chemicals in contemporary use. Recent research conducted on closely clipped Kentucky bluegrass (Poa pratensis L.) with a uniform infestation of annual bluegrass revealed that the strictly preemergence herbicides were ineffective in halting the spread of annual bluegrass when climatic and cultural conditions were favorable for the growth of this species. Effective control was only achieved with an herbicide that provided both preemergence and postemergence activity. Additional index words: Poa annua L., ‘Merion’ Kentucky bluegrass, Bensulide, Benefin, DCPA, MH, Chlorflurenol, Calcium arsenate, Endothall.
