Gallup Biograde Weedkiller RTU 4L - Extra Strong Glyphosate Spray for Effective Weed Control on Driveways, Gardens, Paths & Patios, Quick Application

Works within an hour in sunny dry conditions. Will not work in rain or if it rains straight after treatment. For large areas with a lot of growth 2 or more needed.

I don't know about the weedkiller, but the pump is dangerous, because there are no assembly instructions and it's a very cheap and nasty thing that rarely works. So you're bound to get glyphosate all over you. I did get it to work, but cursed a lot.Wear gloves!!1. Take the clear cap off the far end of the clear tube.2. Shove the other end of the clear tube up into the spray head. Then screw the black bit up into it.3. Take the black head off the spray tip. You can fiddle with that later.4. Take the cap off the can, and the padding bit. Make a small hole in the seal. Shove the tube in. Then screw down the black cap sliding on the clear tube, to seal it.5. Put the can on the ground, stand somewhere with the point level, and pump lots to pump liquid up out of the can. Keep an eye on the tube to see if any fluid is coming up. Be careful not to spray yourself.6. Recheck every joint whenever it stops. Take apart and put back together. Try again.Frankly you are far better off getting a cheap spray bottle, fill it with water, experiment, and then fill it with the glyphosate.A couple of photos attached. But seriously I think this should not be sold. I'm about average handiness, and I suffered. The risk of this poison getting on you is severe, just because of the crummy pump.

Killed everything bar the ivy, it does take time but does do the job well

this is good stuff, I've left it a while to comment as I saw the varying reviewsbasically you put this down, it makes the weeds grow like their life depends on it for about 3 weeks, then they completely die off, I had a huge patch of large weeds well over knee high, put it over all of them, they grew about another 2 foot, then all completely died off, also worked well on our driveway weeds (again which grew lots, then completely diedso far the areas treated haven't returned, like it does with some other brands, no complaints here, may buy the concentrated versions next time as I hear that maybe better again

Was not as effective on weeds as claimed.Was okay but only worked about 50% of the time

This is an excellent weedkiller I have reordered

Well I completely wasted my time and money on this product. Was hoping for a result as some reviewers have claimed but sadly I should have taken notice of the poor reviews as that is exactly what I got resultwise. Nothing!! This product did zilch. Followed instructions to the letter. Dry weather, no rain due, sprayed area twice one week apart. Now 2 weeks on and not a single wilted leaf in sight never mind dead weeds. Might as well have sprayed them with tap water !!! So disappointed I can't put it into words. Gallup is supposed to be a market leader when it comes to weedkiller .... hmmmm. As an honest reviewer, and I have reviewed many things on here, I speak as I find and this is a waste of both time and money. Buy something else.

Always use this. Excellent powerful killer.
