5 days ago I treated a few lawns (KBG) with Ferromec ac (6.5 oz/1000) and Trimec 992 (1.5 oz/1000). This is the first time I have used the Iron and what a disappointment!! Instead of the lawns turning green they whiteish gray color. Did I somehow burn them?? Thankfully I only experimented with a few customers. Needless to say they aren't to happy. Will the grass eventually become out of it?
