I just finished my last rounds of Barricade yesterday. Most of my customers will water in their pre-m...even those without irrigation. For some i will leave them a tower sprinkler to water in the herbicide. Grassmasterwilson. We are supposed to get some rain this coming weekend. This may be a good week to apply your pre-m. i would have waited but I'm getting a little bit nervous about pre-m apps in October. It just seems to go against the traditional wisdom of September 15th.....the supposedly magical date.
