Andy Jorgensen said: How green are you? I'd be cautious spraying Ronstar on green turf. Better to look at the 2G, IMHO.
Right now the only green we have is poa. Is that green you worry about in the Bermuda or zoysia?
That might be why everyone around here goes mostly with Barricaid? I do hear of some people using Ronstar early.
I am also thinking about putting some Goose/Crab on my worse green in the spring and running a trial on my practice green. Bent grass, Some of the bent might be green by then? I remember doing that either my first or second year here, we had a USGA visit, and the agronomist told me I was brave, because if we made an application mistake in the transition area it would be around all season. so I have avoided it since.
I have to wonder when it comes to my greens where we have been using different formulations of dithiopyr, could I be putting it out too early, we will see goose in fairways, tees, and warm season collars much earlier than the greens, or it could be the later timing of the split applications on greens holding off the goose?
It is so frustrating as I try to figure out the answer, as the more I dig into my past records, the more questions I have.
Thanks!
