I see ronk has answered the question for you regarding rate and split application of two different pre-emergents. In my case Doveweed is such a serious issue at this point I need to go with Specticle in the spring, I’m just tired of using post-emergent control on it.

And do watch closely your second window of application of pre-emergent, say April, relative to soil temp (70 F). I missed my window of spring application of Specticle for Doveweed control last year by focusing on a calendar date application more so than soil temp. And b/c of the warm winter we had in 2019-2020 Doveweed seed germinated prior to my targeted calendar date application, about 3 weeks earlier than usual. I won’t make that mistake this year.
