Tenacity applied

Having confirmed to a good enough confidence level, I ordered some Tenacity herbicide and applied it on Thursday (8/1). I couldn't find any dish soap to use as surficant that I was certain was non-ionic so I ended up purchasing some Bonide Turbo Spreader Sticker Concentrate online (not sure why they couldn't have just called it "Surficant", but anyway...).

Tenacity Herbicide & Bonide Turbo Streader Sticker Concentrate

This is what the label said for treating bentgrass:

Control of bentgrass (Agrostis spp.) and nimblewill (Muhlenbergia schreberi) - Apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre at two to three week interval for up to three applications. Apply with a NIS surfactant. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications.

So I followed the label of both and mixed up 1 gallon of water with 1 tablespoon of the surficant and 1 teaspoon of the herbicide, and I applied just about all of it using a handheld sprayer. I also sprayed about a foot or so around the patches as I read somewhere that it'll help make sure to make sure to get all the stolons. I'm hoping to reseed these areas this fall, but if it takes 2-3 applications separated by 2-3 weeks that would mean seeding August 29th at the earliest (2x2 weeks) and October 3rd at the latest (3x3 weeks). We'll see how it goes.

Here are some before shots showing the creeping bentgrass in the lighter green (3 different angles of the same area):

It has spread impressively since last year when I first discovered it!

I'll try to post the progress. It should be interesting!
