Gly Star 5 Extra (2.5 Gallons) by Agri Star - Compare to Roundup Custom, Glyphosate Concentrate...53.8%

By far the best weed killer you can find. Highest concentration of Glyphosate I can find at 53.8% and costs almost half the price of some other brands that are only 43%. My go to weed killer. Highly Recommended, A+++

Works great. I had been using RM43 but the price doubled over the years. The only drawback is it does not contain Imanzypr. This chemical prevents regrowth of new weeds. But I purchased separately and mixed it in. In 3 years of yearly application, 90% of my land is down to dirt all year long. Neighbors weeds are about 24" tall and cover 85% of their land. It works!

Works perfectly to kill whatever I spray it on

This week killer works like Roundup but is much cheaper. It kills the weeds but don't look for them to die overnight, it takes a couple of days for them to look like they are dying but then they die completely.

This Gly Star 5 Extra, 2.5 gal. (53.8% glyphosate) glyphosate concentrate is, in volume, 150% increase over Roundup Super Concentrate Weed & Grass Killer, 1 gal. (50.2% glyphosate) and is about 7.2% more concentrated. Factored into this along with the cost per gal. difference, there’s a savings of about 74% over the Roundup version and they are equivalent products (active ingredient being glyphosate).The only significant difference between them is that Roundup has easier to understand directions (for me at least). Roundup says use 2.5oz/gal. for best result. Gly Star 5 comes with 70-page booklet (or you can download a PDF version) and it’s ridiculously difficult to figure out oz/gal. I eventually asked a question on Amazon’s product page and someone kindly said that 2oz/gal. works fine for them.So, I mix from 2.5 cups – 3 cups per 10 gallons, a bit over the suggested 2oz/gal and I’ve had great luck with this product.

Does the job, kills weeds, good value for money.

I like this 54% glyphosate because it has no surfactant so it can be used in wetlands and it does not foam in an herbicide sponge applicator, thus flowing better. I use it full strength in the spring when sap might be flowing, full strength in the winter so it doesn't freeze down to 10 degrees F., and half strength in summer and fall to make it last longer.

This is the only weed killer my husband will purchase. It's very effective.
