From a cost angle per application, I think dfw_pilot is spot on.
However, I couldn't help myself and wanted to have a better handle in terms of what wasn't going to be picked up by the aforementioned Bermuda Triangle. The main category that kind of sneaks by is post-emergent control of grass-like weeds. With that being said, hopefully the pre-em controls most of them, if they are annuals.
As a result I wanted to know if there was a substitute for any leg of the triangle that would broaden coverage, still be cost effective, and be safe to apply no matter the temp.
TL;DR - The best alternative I found was replacing Certainty with Monument to pick up a few additional grass-like weeds, but it's going to cost more.
I also didn't want to sacrifice sedge control for the grass like weed control. For sedge control, I looked at several different university studies to see which products stood out. The contenders to me were either Monument or Certainty. In terms of cost per application, Certainty is a better value in price for app vs Monument at pricing, as of July 1st 2017. Certainty came out to $2.09 or $3.32 per application, depending on the rate, and Monument was $4.60 per application.
Reading the labels, there are a few grass-like weeds that aren't picked up by a mixture of Celsius and Certainty, such as smooth crab grass, signal grass, rescue grass, and torpedo grass. With that being said, the tank mix of Celsius and Monument or a tank mix of Celsius and Certainty could both be equally effective at controlling all the aforementioned weeds, even though they aren't listed on the label, I just haven't tried first hand.
I don't want to be in a situation where I have a bunch of different 1/2 Gallon bottles of herbicide where I've used 6 oz.
I bought a house where the lawn hadn't been maintained in at least a decade.
For my own personal use, I've use a hose end sprayer for a broadcast of a three-way (2,4-D, Dicamba, and then something like MCPA). Afterwards, I put down a DImension (dithiopyr) pre-em for the next season and started using Celsius to spot spray for weeds.
The only other thing I'd considered was doing a broadcast of quinclorac to go after the grass-like weeds hiding in my yard. Currently, I have yet to go that route and have stuck with hand brushing with glyphosate when I discover them.
