Fall Timing of GameOn and Relzar Herbicide Application


Abstract

Turfgrass managers have many options for broadleaf and grassy weed control, although new chemistries for the turf market are rare, especially in the case of weeds deemed as “hard-to-control.” Examples include ground ivy (Glechoma hederacea), thistle (various species), and wild violet (Viola sororia). Effective chemical control of this group is limited and cultural controls have minimal effect due to these weeds’ ability to persist in growing conditions unfavorable towards turfgrass. A new active ingredient, halauxifen-methyl, available to the turf manager in both GameOn and Relzar, shows promising results on both easy-to-control and hard-to-control turfgrass weeds.
