Q: How Long does it take to dry

  • A: Howdy neighbor! FarmWorks 41% Glyphosate Concentrate takes approximately 2 hours to fully dry and become rainfast after it is sprayed onto weeds. For the absolute best results, you should apply it on a warm, sunny day above 60°F when no rainfall or lawn watering is expected for at least 24 hours.

Q: Will this product kill chameleon

a month ago
1 Answer
  • A: Howdy neighbor! FarmWorks 1 gal. 41% Glyphosate Grass and Weed Killer Concentrate will kill the chameleon plant (Houttuynia cordata), but because it is an incredibly aggressive, waxy perennial, it will likely require multiple applications to completely destroy the deep root system.

This Stuff Works Great!

2 years ago
I live in south eastern Arizona, and I have been using this product since 2017 both at my work place & at home. Here we have some very stubborn "weeds"... mesquite, catclaw, Russian thistle (tumble weed), bermuda, nutgrass, dandelion and a whole host of others I dont know the name of. At work, I have approx 1500 feet of chain link around the property and this stuff keeps the fence line free of EVERYTHING so I dont have to chew up a ton of weed eater line. Same story at home with less fencing. I highly recommend this stuff to everyone in my area. I us 4oz of product to 1 gallon of water in a hand pump sprayer, spray everything that is GREEN (dont spray bare ground, it wont do anything) that I want to be rid of, and in about 7 days the item has yellowed to the point where you know its dead. I have found that for maximum effectiveness, spray your mixture right after you have weed eated the area. The exposed cuts seem to drink up the mixture quickly. This product kills from the root up, thus it takes several days for VISIBLE results, and it has been very effective for many seasons. Over the years, I have had to purchase less and less of this product simply because I dont see very many weeds along my fence lines any longer.

Must be a bad batch

7 years ago
The last 14 gallons I purchased may 2 2019 must have been a bad batch. We have used farmworks for years and we normally see brown down within 5 to 7 days. Not with this batch though. Have sprayed twice since 5-2-2019 and fields are still bright green. The cost of the concentration is only a small part of the cost of using it. You also have to figure in the cost of oporating the machinery to apply it. When your tractor uses 3 gallons of fuel a hour to run it gets expensive to fix some chemical company's screw up.

Great Product for Hack and Squirt Applications

a month ago
I purchased this product to kill Tree of Heaven on my property. Where I live this tree is an invasive, fast growing problem plant. The main focus was eliminating a mature tree about 11-12” in diameter as well as other much smaller individuals nearby. I used a hack-and-squirt method which involves cutting relatively small gashes around the tree to receive small quantities of the herbicide. It’s, however, very important not to girdle the trunk. Leave space between your cuts and perhaps move up or down the cut line which can be two feet or less from the ground. After making the cuts I filled each cavity with a couple mL of herbicide. There were no obvious impacts on the tree for a couple weeks and then fronds began falling to the ground. The tree has continued to lose leaves and fronds from the structural parts of the tree. The smaller individuals have all died and turned brown. I expect all elements of the tree will expire very soon. This concentrated glyphosate product performed exactly how I expected. I have no reservations about recommending it for projects similar to the one described above, and most likely for other brush killing duties in accordance with the manufacturer’s instructions.

Yes, I recommend this product.
