Customer Reviews for Q4 Plus Turf Herbicide

For the past 6 years I have been manually pulling the broadleaf grasses and they just never end. Q4 Plus has done the trick and all broadleaf's are turning brown. The lawn is looking beautiful now. Whenever a new broadleaf pops up I just give it a quick shot of Q4.

Have been fighting Creeping Wood Sorell for years. Tried digging it out but ended up just pruning it. Box store weed killers did nothing . Within 2 weeks of spraying my entire lawn with direct spray on the Oxalis, it all but disappeared. No damage to lawn. I did find I had to do 2 applications in areas where there was more dirt than grass but it knocked out. It killed plenty of other weeds but it did the job on shutting down the spread of Oxalis.

I didn't use most of it within the "3 hours" recommended after diluting. I did not have great results. I will try again using it immediately and repost results.

Works as advertised. Mixed in a two gallon sprayer with some surfactant, dye so i didn't over spray, and water. Killed the hell outta my crabgrass and yellowed the Bermuda a bit but i was aware that could happen and its already healing.

I applied this the during the evening at 68 Degrees F and the following days we hit 85 for highs. I applied at the higher end of the dosage rate recommended. This laid waste to all the of weeds in my Bermuda grass, I would suggest applying at a lower rate, around the edges of my lawn where I went a bit slower to definitely catch all the carry over I was getting from neighboring lawns. This was wholly unnecessary and I likely applied more that 3oz/1000 it made all the Bermuda go dormant too, it has been about a month and a half and you can still notice the edge. But it definitely works, in areas where I applied an appropriate amount there was a bit of yellowing but not bad for how hot the days were very happy with this product!

I could see it starting to work on the second day. A few days later the weeds were obviously dying off. And great customer service in helping me choose this product.

Bought this to control crabgrass in my tall fescue lawn. Unfortunately, I didn't put down a pre-emergent this year, so I've had crabgrass popping up all over the place. Followed the directions for spot treatment and seems to be working well. The larger clumps of crabgrass have taken a few treatments, but are starting to finally die off.

My first application was Mid-July and sprayed over the entire (4000 sq t) yard. After a couple of weeks, minimal change was seen and, as well, there was new crabgrass growth. I re-ordered and this time applied only to the crabgrass. As of this writing, there has been marginal success (about 20%). Yesterday, I pulled a 2-gallon pail of crabgrass from the yard and still have about 75% of the yard remaining to weed.

I had large patches of Virginia button weed and some crab grass, mixed with some carpet weed. I was really happy with the treatment on the Virginia Buttonweed which was my primary problem. It was somewhat effective on the crabgrass and carpetweed.

We live on a lake with a large front and back yard. Strange unidentified grasses have invaded our Bermuda grass and broad leaf week killer was not effective. This product did exactly what the label said. The Bermuda is alive and the mystery grass is brown. We have now applied fertilizer to feed the Bermuda. We are no longer feeding unwanted grasses. We will be ready to do this again next Spring if necessary.

If you knew me, you would know I expect things to work immediately. Now this product does work but not immediately. So be patient and it will work and it won't kill off too much of your grass. It does some but not as much as I expected. I would recommend.

Make sure you follow the directions not really clear on how much product to water I need to have a YouTube channel for all people instead of reading the directions because it's a little confusing but overall it did a great job

Q4 Plus works great. I had various weeds, dandelions, purslane, yellow nutsedge, and clover on a couple of my properties. After using Q4, the weeds were dying within a few days. I use this stuff 2 times a season and fertilize with PGF complete and have the best yard around.

I had some crabgrass around my curb. I mixed some Q4 1:4 with a surfactant and it knocked out the crabgrass!

Was this review helpful to you?  YesNo

yes,the q4 killed/burnt d crab grass which is on half of my lawn at this point..but how do I fix the yellowness of the killed/burnt spots.lawn doesn't look great with the look was scared of spraying the whole lawn cos I did not want to burn my whole lawn.

  Expert response:
Per the product label it does state that it may cause discoloration and it is recommended to test a small area to determine the acceptability of turf discoloration. The addition of nitrogen fertilizer or chelated iron may reduce some turf discoloration.

Stuff works well. Don't mix it on the weak side or it will make it look ineffective. Does a good job in cool season KBG at not hurting the lawn but wiping out crabgrass, dandelions etc. Will be less effective on larger, mature weeds that are already hard to control. I spray 2 acres of KBG and this last time doubled up with Q4 and Drive XLR8 and smoked 90% of the mature crabgrass in he lawn with 1 app. Just be patient with both and you will see results.

I used Q4 about a month ago and I’ve seen improvement. A few weeds slipped through but I will hit them with a second application in a few weeks and see if that works. So far I’m happy with the product.
