Customers find the weed moss control agent easy to use. They mention that it has 2 locking points to help prevent accidental spray, it's easy to apply, and to read directions. They say it'll kill weeds within hours and that the sprayer makes it so easy to control and direct the product exactly where they want it.

Customers are mixed about the performance of the weed moss control agent. Some mention that it really works and isn't toxic to every plant. They say it works well on most weeds and is effective when there are consecutive days of high temperatures.

Customers are not happy with the color of the weed moss control agent. They mention that it turns everything brown and dead to the seed, and it will turn your green grass yellow. Some customers also say that it only makes brown spots and doesn't kill the plant.

"...It started killing about 10 minutes after sprayed it started turning brown and now it looks like hay...." Read more

"It leaves stains on concrete driveways, I’m not sure if it’s because I made the mix a little more on the concentrated side (just to be sure it kills)..." Read more

"...the area I used to prepare this product that this stuff leaves a very solid white stain on wherever you’ve placed the container when some product..." Read more

"...Works fast and great. Be careful near lawn because it will turn your green grass yellow. Just a bit for me but nothing too noticeable" Read more

Just the thing for problem spots

Just the thing for problem spots
The ramp in the photo is too wide and low to weed underneath with any tool I have. It’s so big and heavy that if I pick it up to weed, it’s tough to replace it without damaging the building. I’ve depended on glyphosate. In my experience, it takes several days to see if glyphosate is working. During that period, weeds keep growing and I don’t know if I need to spray again.The last time, it took a week to kill the weeds. Two days later, new weeds were already quite big. I bought Groundclear to work faster and longer.A gallon of concentrate makes 5.3 gallons of mix, so it would be expensive to spray a large area. I made a liter. I put the bottle of a 2-liter pump-up sprayer on a scale, added 190 grams of concentrate, and added water to bring it up to 1,000. That was plenty for the ramp area and to test on other trouble spots.Later that afternoon, the crab grass and wire grass looked rusty and wilted. I took the photo 24 hours later. The camera still didn’t show had bad the leaves looked. I had also sprayed broadleaf weeds. I kept an eye on them for 10 days and saw no change. Maybe their leaves were more water repellent. Next time, I’ll add a little dish liquid.Pelargonic acid "burns" leaves. It’s 1% of the spray. It’s a fatty acid that’s in some human foods. It harms only leaves, and some weeds can grow new leaves.Imazapyr is 0.1% of the spray. Absorbed by roots, it kills plants. That rules out using Groundclear near shrubs or trees. In the soil, its half-life is in months, so it may work for a year. It helps to wash it in soon because light reduces the half-life to days.Keeping weeds from sprouting would greatly reduce weed problems. I’ve found that an application of Prodiamine will prevent sprouting for a couple of months. It takes only 5-15 grams per thousand square feet, so it’s cheap to use. For smaller jobs, I have a scale that reads to .01 gram.Prodiamine doesn't kill existing weeds or prevent encroachment, so Groundclear offers more protection. I’ve ordered a 1.5-liter sprayer. I don’t anticipate needing so much at one time, but if I keep the sprayer in a cardboard box to protect the herbicide from light, I’ll probably use it often.
