Annual Bluegrass (Poa annua) Control in Creeping Bentgrass Putting Greens with Amicarbazone and Paclobutrazol

WEED TECHNOLOGY, 27(3), 520–526.

By: M. Jeffries n, F. Yelverton n & T. Gannon n

author keywords: Digital image analysis; injury; quality; turf spectral reflectance; weed control
TL;DR: Results indicate amicarbazone usage on creeping bentgrass greens may be beneficially affected with the incorporation of paclobutrazol to treatment regimens because annual bluegrass control with the combination was equal to or greater than stand-alone amicarazone applications, and creeping bent Grass tolerance was superior 8 and 12 WAIT.
