Product Overview

HDX Weed and Grass Killer Concentrate kills unwanted plants by inhibiting the production of a substance found only in plants. It enters through the sprayed foliage and moves down to the roots. Avoid direct spray or drift onto desirable plants, lawn grasses, shrubs and trees. Protect desirable plants and vegetation with a piece of plastic or cardboard. If desirable plants are accidentally sprayed, wash with water immediately. Any HDX Weed and Grass Killer Concentrate that is not absorbed by the plant is broken down into natural materials. This product has no soil activity. Do not mow, cut or otherwise disturb treated vegetation for at least 7 days following application. Most treated weeds usually show initial symptoms in 2 to 4 days and complete kill in 1 to 2 weeks.

  • Visible results in 2-4 days
  • Kills the root
  • With surfactant
  • For best results apply during warm, sunny weather (above 60°F)
  • Harder to control weed or large weeds may require a repeat application
  • Apply when weeds are actively growing and no rain is forecast for 24 hours

What about animals and HDX

I sprayed around a mesquite tree where the pods from the tree fall. My horses like to eat the pods. Will it be dangerous for them to eat the pods 7 days after I have sprayed the HDX? If I spray for weeds in the pasture will it be dangerous for my horses?
Asked by: David
HDX is very potent and it could affect live stock and domestic animals so you should be very cautious.

How long to wait after application until it is safe to seed the treated area with tall fescue?

Asked by: revo
HDX is a very potent and strong herbicide (active ingredient Glyphosate 41%) which stay active for over 2 weeks so you should wait. Or as soon as you see that all weeds are dry you can give it a try.

32 oz. Weed and Grass Killer Concentrate is rated 3.2 out of 5 by 32.
Rated 5 out of 5 by from I did some research on Round Up and other brand name weed killers and this is what I found... Bas... I did some research on Round Up and other brand name weed killers and this is what I found... Basically all "weed and grass killers" have the same active ingredient GLYPHOSATE ISOPROPYLAMINE SALT which is what kills the weeds & grass. This is not a "selective herbicide" and it will kill all vegetation so you should not us it on your lawn to kill weeds. It will take a week or so to kill all your vegetation. All the hype about other brands that advertise "2 to 3 hours" or "next day" dead weeds is a scam. These products, like Round up, have different chemical additives that will discolor the weeds to make them look yellowish or light brown and you will think that they are dead which is not true. That's what these name brands want you to think. It will take a week or 2 for all the vegetation to die. Some have higher concentration than others but they are ALL THE SAME. I was informed by a farmer friend that if you add a couple of table spoons of table salt to the recommended mixture that it will help some and if your weeds & grass is high add an additional table spoon or two of HDX concentrate which just might do the trick... He also suggested that you can spray every other week for very infested areas. But it's like he said, "you must be patient and give it time to work". So save some cash and just follow instructions as listed on the bottle and you will be fine and weeds with be DEAD as advertised. BTW, best time to spray is on hot dry days with no rain in the near future, at least 2 to 3 days. That's what I do and it works just fine.

Rated 5 out of 5 by from great product & money saver What a savings and great results.If you want immediate kill stay with round up, but if you want total kill use HDX. It takes longer but worth it. Caution, works on grassy and broadleaf at general weeds, but if you read instructions on how to kill perennials use 2.5 fl. ounces,not 1.5 per gallon. Very impressed and must buy.

Rated 5 out of 5 by from HDX WEED AND GRASS KILLER Have used other products and the weeds came back. Used HDX as instructed except add 1 tablespoon of SALT. Look at the Roundup Pro it has sodium. With this formula it will kill anything in 2 to 5 days. Make sure what you spray you want to die, because it will!!!

Rated 5 out of 5 by from Use common sense folks glyphosate.... is .... glyphosate.... okay let's use some logic here.... this is the main active ingredient in almost every weed killer on the market.... it works very very well.... although other brands work twice as fast they also cost twice as much ! I couldn't be more pleased with the results of this brand .... it took about 2 weeks for total weed destruction.... don't believe the other reviews.... use common sense ... glyphosate is glyphosate .... you can either microwave tough meat ... or crock pot it .... slow and easy wins this race for HALF THE PRICE !!!

Rated 5 out of 5 by from Great Product! It will not disappoint! I finished all of my Round Up concentrate and wanted to find a cheaper alternative. I saw this on the shelf and decided to give it a try and I was naturally worried it was a waste of time and money but I was wrong. This product is better than Round Up in my opinion. First the value is great being less than half the cost of Round Up. Second the effectiveness is incredible. When I got home I mixed the solution into my garden sprayer according to the directions. I have a 2 gallon sprayer and I mixed enough to fill it because I had a lot of overgrowth that I needed to take care of in my gardens around flowers and I wanted to do some liquid edging around my sidewalk and driveway. The difference is the time of visual effectiveness between this product and Round Up. Round Up I could usually see some type of wilt on the weeds by the end of the night if I sprayed in the morning. This stuff is much different. Two or three days later it will still look like you didn't spray but let me tell you, the next day it looks like you unleashed chemical warfare on those weeds and unwanted grass. It did not affect my flowers (I did take care to not get much on them). When this stuff decides to attack it doesn't hold back. This stuff killed plants that were persistent with Round Up and they didn't just fall halfway down, they were in full on decay by day 5 or 6. I mixed a little more in a spray bottle for some spots I could see I missed and it was just as effective again. You won't regret this purchase, it is the real deal and will save you considerable money over Round Up concentrate.

Rated 4 out of 5 by from How to improve effectiveness For those of you disappointed with your results, I say this is all about chemistry and botany. This has 41% "Glyphosate". If you used the prescribed 1 1/2 oz. per gal. Your results will occur, but, very slowly, taking weeks and weeks for very resistant weeds. If you want to see faster, more visible results, increase the dosage to around 3 or 4 oz. per gal. Also, for those who feel other products are better, like Roundup or Sprectracide, look at the dosage per gallon. I think RU is 6 oz/gal and Spect. is like 7 oz/gal. These products are NOT magic in a bottle. It's chemistry !! I used 1 1/2oz per gal and after 2 weeks started to notcie a difference and after 6 weeks, saw visible signs of the plants demise. This is on "Garlic Mustard Weed", which is tougher to kill than say grass or dandelions. When I increased the dosage to 3 oz/gal. on the same type of weeds, I saw a slight change in 3 days, or visible decline in 1-2 weeks. So increase the dosage, if you want quicker, more assured results. What your really paying for is the "Glyphosate". That's the active ingredient that attacks the plants. If you really want to see quick, fatal results, use the dosage that RU and Spec. call for. Oz, for oz, HDX is the cheaper, less expensive product, generating effective results, in my opinion.

Rated 5 out of 5 by from VERY effective, economical alternative to Roundup...just follow the directions! I've used this product all season with great results. The active ingredient, glyphosate, is the same and in the same concentration as Roundup Pro, and has been equally effective in my usage. Mixing to stronger concentration levels doesn't improve effectiveness, it just wastes your money. Just remember to read and follow the directions dummy! Apply when the weeds are growing and actively transpiring (when it's sunny), preferably in the morning when it's calm and there's no rain in the forecast. Then, wait and be patient... It takes several days to kill. I'm trying to control weed growth in over 4 acres of gardens and HDX is a great money saver!

Rated 5 out of 5 by from Roundup is all for show Roundup has another ingredient that turns weeds yellow quickly, so you think they're dead in a few hours, but it takes much longer. Glyphosphate is what kills the weeds, in a couple of weeks. This product has the same end result as Roundup, at a fraction of the cost.
