I did my calculations just this week with Esplanade which is similar. My math told me that 1.6ml/M of 19.05% equaled the 6oz/A rate of Specticle. I went with 1.2ml/M rate (4.5oz/A Specticle) to mirror the Specticle multiple application rate found at the top of page 8 in the Specticle Flo label. I will do this three times at 45 day intervals for my SA and common Bermuda areas.

.87ml/M of 19.05% seems to be closer to Specticles 3oz/A rate. I can’t speak to the effectiveness but that number still seems to fall within the Specticle range for multi apps.

Its early and I’m pulling the numbers off the top of my head but I have to be close lol

 

Checking out the product for the first time but this seems like the Rangeland/Pastureland label of the Indaziflam 19.05%. Do a search on this site for Esplanade 200 sc and you'll get conversions.The difference seems to be that the Rezilon label limits the annual max at 6oz/A, whereas Esplanade also specifies a non-grazing site (roadsides, industrial, etc) maximum of 10oz/A.

Are you managing grazing / pasture grass? If not you can do what most of us do and follow the SpecticleFLO label.

EDIT: for quick reference, and to confirm @Focal's math:
3 oz/A of 7.4% Indaziflam = 1.165 oz/A of 19.05% (~ 0.8 mL/1000)
4.5oz/A of 7.4% Indaziflam = 1.75 oz/A of 19.05% (~ 1.2 mL/1000)
6 oz/A of 7.4% Indaziflam = 2.33 oz/A of 19.05% (~ 1.6 mL/1000)
9 oz/A of 7.4% Indaziflam = 3.5 oz/A of 19.05% (~ 2.38 mL/1000)

 

Just looking at the Specticle label again, but it appears that less than 1.6ml/M of 19.05% may not control broadleaves and less than 2.4ml may not control annual sedge and kyllinga.

 

This is why @Mrbossman needs to be aware of what weed he's after. Different rates and application timelines for different purposes. So while the math may be right, the application amount may not give satisfactory control.

Btw @Focal isn't it odd how the label specifies a lower possible rate for the likes of PoaA and Goosegrass than it does for Broadleaves?? Weird.

 

These were super important while I was figuring out my specific math. Many of the converted max app rates I found when searching were at the higher 10oz/A Specticle rate, but then realized I needed the lower 6oz/A max app rate. Next season I will probably work up from the 4.5oz/A Specticle rate to the 6oz (1.2ml/M to 1.6ml/M 19.05%)
