RM43 and Off Brand Glysophate
Attempting to kill some English Ivy in my backyard, I have used 2 rounds of Compare-N-Save 016869 Concentrate. Gone over the area once per 2 weeks. Bottle says 41% glysophate in it. Problem is the leaves are only yellowing slightly in some spots but nothing else in other places. Was hoping to get more than that effectiveness.

Enter, RM43, which is also a glysophate concentrate that is slightly more expensive than the Compare-N-Save version. Do any of you have any experience with either/or of these? Will the RM43 do more damage than I am currently getting with the Compare-N-Save product?

Try using trichlopyr herbicides - you might find it more effective. Like glyphosate - there numerous generic brands.

Are you adding a surfactant to the spray solution? English ivy has a waxy leaf - surfactant will help the absorption of the herbicide by the plant.

I haven't. Anything you particularly recommend?

You can buy this at garden centers, hardware stores, farm supply stores, but not HD or Lowe’s. Add 2 teaspoons per gallon of spray solution.

P.S. systemic herbicides like glyphosate or trichlopyr take time to translocate through the plant to kill it, particularly a tough vine like English Ivy. Be patient, but persistent. Might take a couple months + to kill it but continue spraying it, I’d suggest at 3-4 week intervals until it dies.

Mix 24d and 41% glyphosphate

Add water. Add a half cup of dawn for 15 gallons.

Kills almost everything.

Even banana trees and wysteria

I get mine at the feed store, kills everything and I use a lot (farm, hunting, food plots). What I get for 50 bucks would cost 250 at Walmart or Lowes. I think it’s called ranger pro. As a bonus all the old coots there laugh at masks and social distancing. We still shake hands and say howdy.

I took out some Greenbriar with Tahoe and Finale. Tahoe is the Triclopyr that Craw is talking about.

I have been using a traditional 41% Glyo mixed with 24D for years.

I recently started using RM43 for areas that I spray over and over. It is supposed to last for up to 1 year because it contains imazapyr. I'm only a few months into my experiment but so far so good. I'm not seeing any new growth in those spots after about 3 months.

If it's in a shady area, it takes alot longer to kill. The shaded ivy's and vines I sprayed this year took a month to start dying, the sunny spots were dying in 48 hours.

This was with Roundup's Ivy Control mix, which is glyphosate and trich (i think).

Can this formula be used in an "Ortho Dial N Spray" sprayer? If so what flow rate per gallon would you use? I have a large area I need to spray.

Not familiar with that sprayer. The ratio given will kill just about anything regardless of the sprayer I would imagine

If he is using 41% glyphosate, he is using the surfactant that is already in the mix. There is no need to add a surfactant.
