Spraying Roundup

[SCDolphin]

Is round up toxic to use to clear a garden of grass before planting eatable crops like corn, melons & tomatoes. I did not think it was but one of the neighbors was even concerned it would affect the ground water.

Last question with a 50% strenght anyone know the minimal dilution that will kill weeds and grass.


Thanks

Glyphosate is soil inactive. Once it hits dirt, it has no effect, no carry-over, and is neutralized. It's only effect is on LIVING plants. It won't kill grass if it's dormant. I've used it for years in growing, established gardens to kill weeds. I use a 2 liter soft drink bottle with the bottom cut out, the the spayer wand stuck down through the neck of the bottle. That bottle covers the weed I'm trying to kill and prevents drift from getting on my garden crops.

Buying Roundup in the regular strength, the mixing rate is usually 1 or 2 ounces per gallon of water. If you will mix 2-4-D with the roundup in its regular recommended rate you will find you get a better kill rate. Just a tip that is commonly used in our neck of the woods.

FarmWithJunk is right. Here's some neat additional information about glyphosate:

Please don't read my reply as a "wise a@@" answer, but what you should do is read the label on your roundup. It will give you answers to both of your questions. If you don't have the label for some reason, then go to the manufacturer's website Monsanto ~ Home .

The only safe and right way to apply herbicides is by reading the product label and educating yourself to the correct way to apply it.

Not "wisea@@ information" at all. In fact, complying with labeled information is the only "legal way" to apply ANY pesticide, according to the EPA.

Farmwithjunk is right, Roundup is inactive once it hits dirt. Here on the farm we use 3-4 ounces per gallon in backpack sprayers. A little ammonium sulfate mixed in helps as well. We also only wait a day for it to translocate in the weed, then start cultivating fields.

Hey, mixing 2-4-D is a little diffrent, does not 2-4-D unlike Round Up have a 1/2 life of about 30 days or so... don't recall the specifics, but I know we do not use it anywhere it might come in contact with or even blow on the wind near vines... and I think it does have a "do not harvest" date on many fruits etc...

Bottom line read the labels... it is important!!

I've used glyphosate like Farmswithjunk, with a 2 little plastic bottle cut in half over the end of the spray head. I use this to zap weeds in the veggie garden when hoeing could be potentially more dangerous to the plants. I also use it around the edges, underneath the electric fence.

Glyphosate gets tied up (chemically) by clay particles in the soil. We generally tell people to wait about 10 days before applying seed to soil sprayed by it. In spraying it, you want to just barely wet surfaces of green plants you want to zap. Don't overdo it.

I once used one of those "weed and feed" fertilizers. It killed many things around the edges of the yard that I didn't want killed. It has 2-4D or similar broadleaf weed killer as the "weeder". Never used that stuff again.

Yes you don't want to even show the 2-4-D can to grape vines. They are very sensitive. I am not recommending spraying it around edible crops. I thought the original question was to clean a plot of ground for a garden area. NO EDIBLE crops in the ground or around the area. If you spray simply Round Up...in its original configuration....depending on the temperature and growing condition it will take seven plus days to start the kill. If you mix it with the 2-4-D it will begin its kill in about seven days and then the 2-4-D makes the plant grow faster and accept the Round-up thereby giving you a better kill.

I might add that this is pretty standard practice in my country. In this area they grow field corn twelve to sixteen feet high, and the last time they planted potatoes on my property they went 575 sacks to the acre. Nationally the average is or was about 275 to 300 sacks to the acre. Grain goes about 165 to 200 bushels to the acre. I don't believe with yields like that farmers would be using things that would make the plant in-edible or goof up the ground.

One thing I've noticed about roundup is that it is far more effective on grass than it is on weeds. I'd say less then 1 ounce per gallon will take care of grass. For many weeds, if I apply 2 ounces per gallon, I'll have to come back in a week or two and hit them again.

The reason I posted this is that the label on my gallon jug got wet and stuck together and I could not pull the pages apart to read it

Thanks for the quick feed back

Never use gly. in a steele tank/sprayer! It can explode!

For grasses and thistles, I would mix 3 oz per gallon; for poison ivy and brush, 6 oz per gallon. Round-Up will not permanently kill dandelions- they come back after about 6 weeks looking like they were fertilized. You have got to use 24D on dandelions.
Also, look at the label. Cheaper RUP has less glyphosate than some of the more expensive brands.

 

[RalphVa]

You don't HAVE to use 24D on dandelions. Letting them be or digging them up with a dandelion digger works just fine.

[nwphil]

Letting them be is ideal, but they really take over a lawn and make the neighbors upset. More importantly, they absolutely devastate a young soybean crop.

Has anyone bought Roundup yet this year? I went by the Co-op to get some today. I did not see any on the shelf. "The man" told me the patent was up on "Roundup" and it was going by a new name. As I'm typing this, I have forgotten the new name and the jug is in the back of my truck. Anyway what I bought is made by Monsanto, the original Roundup people. He also told me the price would be going up, and I left with a 2.5 gallon jug for $90. One gallon price was almost $70. JC

Roundup has been off patent for about 8 years now. There is a global shortage of the acid used to make glyphosate though. A gallon of generic roundup cost about $10 last year and it now costs about 30.

The cost of everythings up, I paid 18.50 a bag for 18-18-18 the other day, I've tried some of the "spinoffs" of RU but none seem to work as well as it does

I have a related but slightly off topic question. Is there anything available to really make an area ungrowable (sterile)? Half the time I can't get grass to grow in the yard, but the weeds will always come up thru the gravel on my driveway. Even with the Extended Control RU, I'm doing it at least three times a year. It would be great to find something to drop that to maybe once a year.
