Home Forums Hunting & Shooting Hunter's Campfire Grass Killer Recommendation

I use a mixture of Helosate, Grazon and Remedy ultra with a surfactant mixed in, kills every thing you spray it on.

It might work, but it isn’t cheaper. Safety is debatable.

2.5 gallons of 41% glyphosate is $40. Being extremely liberal in mixing it at 5 ounces to the gallon will give you 64 gallons of spray for $40. 64 gallons of $3 vinegar is $192 plus your salt and soap. 3 ounces per gallon is good enough for most yard plants. That will give you 106 gallons of spray for $40.

I'm no math wizz but WTF?

Didn't kill the aspen/birch sprouts in the lawn when my wife sprayed them. Nice little green growing twigs centered in a patch of dead.....

Personally, I just mow them...

All grasses in my drive dead, dead, dead. Scared the hell out of the plantain as well.

Have your dog piss on it. That kills my grass all the time.

I'd like something to just stunt my lawn. This water, mow, water, mow cycle must end!

Your dog must be a mutant. It's dog chit that kills grass, not pee.

At least with my dogs. Maybe mine are the mutants!

C'mon Boomer. Quit watering and fertilizing, and get a couple sheep. Problem solved!

I've always found that planting maple trees is a sure-fire way to kill any and all forms of grass.

My step-uncle has degrees in soil science and horticulture and works at an ag extension and consults for a golf course developer. His rec, that I followed for similar issues: Compare-N-Save

Stupid name, but frikken stupid good results. Never seen anything like it...

Try this trick on your crab grass. A day or two after your first good freeze, the grass starts to pull it's nutrients down into it's roots for winter, Spray it with 41% glyphosate/water mix.

I did that with a swath of brome I wanted to plant to native grasses and forbs. That stand of brome never came back, but I have a great stand of natives now.

He’s spending $3/gallon+ with his home vinegar salt solution.

For $40 you can buy enough RoundUp to make 64-106 gallons of spray that will kill about any non-woody plant. 2.5 gallons is 320 ounces. 5ounces/gallon gives you 64 gallons (320/5=64). 3ounces/gallon gives you 106 gallons (320/3=106)

Follow?


Buying that much vinegar would cost between $180 and $300.

Had one hard on grass. "Where Dandy goes nothing grows."

Seriously this is a bad time of year to kill grass. Active herbicides need to have grass in a growth stage and grass is usually at least semi-dormant this time of year. Glyphosate at the high label rate will work and kill everything, even glyphosate resistant pigweed we have here. (Even better if you tank mix with a 2,4,D product). Wait a bit. And there's seed on the ground like somebody mentioned. That needs a pre-emergent herbicide like Preen (Treflan) or fertilizer with crab grass control. But that's a spring job so relax for now.

Agreed. Glyphosate plus 2-4-D is what I use when I really want something to die. Crabgrass, if it really is that, is hard to control. Spraying it now is not going to stop it from coming back up next fall. I've seen it sprayed dead, then come back up after a few weeks, because there was still seed in the soil. I'd put down some Preen next spring before the crabgrass emerges, and it will probably take a few years worth of treatments to get rid of all of it.

I would take pictures or better yet fresh cut samples of the whole plant to your local extension office or the weed and pest. Get a positive ID. Common names for the same plants vary around the country, so a firm ID is important.

Then I would ask them for their recommendation and maybe do some of your own research once you have the positive ID.

When you settle on a herbicide read the label and follow instructions. You need to mix the herbicide correctly once you have calibrated your sprayer. Or buy a ready to use product if available for the herbicide you select.

Different weeds are vulnerable at different times in their growing cycle and herbicides work differently from others. 2,4-D is really only effective on broadleafs when they are actively growing. Others can be used when the plants are almost dormant. Glyphosate is going to take at least a week before you'll notice any plant damage. Don't be mowing or cutting those plants in the mean time. You can start to see plant damage from 2,4-D in a few hours sometimes. Sometimes, like spraying Knapweed in the fall, you won't really see results until next spring when not as many grow up.

With lots of species you are going to have a seed bank in the soil and not get 100% kill so total control will take more then a season or two.

Depending on your locale early fall can be a great time of year to kill grass. In places with hot dry summers once you get cooler fall days the grass starts to grow again especially with some rain or irrigation.

Thanks! When you went to 3 ounces, I didn't follow you had returned to the Round Up... LOL

If its an area kill, I've not been disappointed by roundup. If its a spot kill, try boiling water and soak the spot. Boiling water kills all. It works great on ant mounds too.

I still say it's best to ID the culprit weed first... before blasting herbicides all over. Maybe it's NOT crabgrass. It might be a variety of nutsedge... which can be a bear to get rid of. Many of the nutsedge species (yellow, purple, globe, etc.) have triangular (cross-section) stems. Roll it between your thumb and finger. If it's triangular in shape... bingo. Once positively identified, product selection becomes easier.

Note #1- Glyphosate does not kill everything.
Note #2- For herbicides to work effectively, the weed has to be in a healthy, active growing state.
Note #3- Tank mixing some herbicides can be very beneficial.
Note #4- The use of a surfactant / wetting agent may be beneficial. The herbicide label will tell if doing so is advisable.
Note #5- If it is crabgrass, sprinkle baking soda (1 # per 100 S.F.) on damp foliage. Black weeds will soon follow.
Note #6- As already noted, bermudagrass can be very difficult to kill... even with full strength dilutions of Glyphosate.
Note #7- You had better hope the weed is not Torpedograss. It's a S.O.B. to get rid of. Not sure if it even grows in your area but...

OVER AND OUT.

Grum,

is it coming up through fabric and mulch that is put down to keep weeds from around other valuable landscaping plants? If so, you may want to watch how, when, where, you use any herbicide as you likely want to see any effect on your other plants.

If it's Bermuda grass......good luck. I didn't think it grew that far north, but perhaps you're in the southern portion of your state. Nasty stuff, and it seems like if you do manage to get it under control but your neighbors don't, it'll be back as it spreads underground to your place again.

Good luck.
