Help with roundup mixing.

So what is a good available substitute for Ortho Triox?

I maintain a commercial parking lot in industrial zone and one Triox in the cracks and crevices and good...

Now it is every 4 to 6 weeks roundup and string trimmer...

Vinegar/salt mixtures?

How to make homemade weed killer out of 3 household ingredients

A solution of vinegar, salt, and soap sprayed on unwanted weeds will kill them, but it will also kill any other plants it comes in contact with.

It has the advantage of shifting the soil pH, making regrowth in the crack harder for weeds. Of course, once the rainy season hits, the soil pH will reset, but hopefully you have the cracks sealed by then.

All the best,

I sprayed half of the 20K sqft fescue K31 yard with 41% gly this morning in prep for reseeding as a result of getting some bad seed a couple years ago. (It had three or four different varieties of grass mixed for some reason) The other half of the yard is a good stand of clean fescue that was seeded a year earlier from a different batch of seed.

Anyway, the problem I always have in spraying and fertilizing is knowing exactly where I've been each pass. Try to use tire tracks as a guide but that doesn't always work well. So this time, I tried a bottle of blue dye as shown in the pic. The last picture shows the difference between sprayed and unsprayed with the blue dye showing up, ironically, as darker green. The dividing line is fairly apparent directly down the middle of the photo.

The problem was that the dye was not visible while spraying and only slightly visible after drying and then only next to the unsprayed grass. So, I had to resort to using tire tracks as a spraying guide. UGH! I have tried using spaced wire flags in the past but that isn't really a good solution either especially when using a couple passes at an angle to each other.

Wondering what you guys use for guidance when fertilizing and spraying lawns?

It's the gaps from concrete to asphalt...
plus the smallest of imperfections... parking lot is leased but almost no traffic... Never had weeds on surface when lot had lots of traffic but with almost zero traffic amazing how pesky the weeds can be.

If I sprayed my lawn for weeds I wouldn't have a yard. Also I mow plenty often with no fertilizer. Sure wouldn't want to mow more.

Thanks for the great information you have shared. What is the best way to control an early infestation of Johnson grass?

If what you call Johnson Grass is the same as what I call Johnson Grass, Roundup should work very well on it. This weed is usually not found in lawns, because frequent mowing will keep it from growing and spreading. In my experience, even low rates of Roundup are effective on Johnson grass, as long as it is growing rapidly.

I understand what you are saying but on several points I have to disagree. I have used this mixture with great results for years, much better results than Roundup alone. Much better. It kills faster and lasts mutiple times longer. As far as atrazine goes, prior to Roundup ready corn seed we used almost exclusively atrazine as a pre and post emergent herbicide. We sprayed in pre-emergent and mixed it with the nitrogen post-emergent. I've been using a broadcast mix of atrazine and 2,4D amine for years over my turf grass to control early season weeds and primarily sand spurs. I mix it with my Reagent when I spray for fire ants. I use it in my total kill mixture because I have it. As for Pramitol, yes it is a ground sterilant and again I mix it with my total kill because I have it and I hope some of it makes it's way to the soil. With these mixes I usually end up only having to spray each once per year vs mutiple times of spraying with just Roundup. Thanks for your recommendations CTC.

I agree with you that your mix will give you great results and will work quickly, and will last a long time. However, my opinion is that in your mix, the Roundup and 2,4-D are mostly wasted, because the diesel kills and burns the plant instantly, and does not allow the Roundup and 2,4-D to be taken into the plant and be translocated within the plant.

Translocation within the plant is how the Roundup and 2,4-D work to kill the plant, and the kill is slower than with diesel. Using diesel is similar to using paraquat, or sodium chlorate, or even MSMA. The all are contact killers and are not translocated.

And, since the Atrazine and Pramitol work in a similar way, one or the other could be left out of the mix.

I also believe that if you use only Roundup and Pramitol, your kill will be slower than with your mix, but should last just as long.

Thanks, it is coming up in my field. I let my neighbor cut it for hay a couple years ago when my tractor was down waiting for parts. Everywhere he dropped a round bale I have Johnson grass, hemlock or thistle popping up. These guys around here bail anything for hay, he was supposed to clean his equipment.

To kill johnson grass in a pasture you will have to spray Roundup directly on it or use a wick bar.

Talking to myself here again, but I did find some info on homemade foam markers for spraying, fertilizing etc.
Probably will rig one up to just drop foam under the center of the tractor which would be a big help in knowing where I've been and where I haven't.

My sprayer has a broadcast bar that is very wide but the nozzles spray pretty wide, roughly 20 feet wide. How do I know where I sprayed? Mostly guessing.
