How much roundup is needed to kill a plant

Applied improperly, however, herbicides also provide an opportunity for a landscape disaster. Here are three simple steps that will help homeowners and other applicators get the most from their herbicides. Are you trying to control dandelions and other broadleaved weeds in your lawn? Are you trying to keep grasses out of a ground-cover bed? Do you want to stop weeds from coming into a bed of annuals? Do you want to keep a paver patio free of all weeds through the summer?

Do you want to eliminate poison ivy from areas where kids and pets roam? There are products that, if used properly, can achieve each of these results. Applying the right product properly can save time and help produce an attractive weed-free yard. Applying the wrong product can ruin your entire landscape. Herbicides fall into two broad classes: Post-emergent and preemergent.

Preemergent herbicides such as Preen are designed to control weeds as seeds germinate. Preemergents can be very effective in reducing the need to weed annual beds and other parts of the garden. Post-emergent herbicides, in contrast, kill exiting weeds. Probably the two most familiar post-emergent products are Round-up glyphosate and Weed-B-Gon. For several years. Sprayed with RoundUp. Knocked it back a bit, but always came back. What worked was a cup full of houseplant fertilizer blue crystals dumped in the dead center of the stump.

Killed it! A cottonwood tree that was cut down continued to grow back in spite of spraying with various poisons, cutting again and again, and burning. I suggested that my client cut it back again and then build a compost pile over and around it. She put some inexpensive wire fencing around the trunk and filled it with leaves plus some vegetable and fruit peelings.

The trunk began to decompose and never grew back again. I am out picking seedlings every day. Ignore the copper nail…nothing kills this crap except poison. Take a drill and drill holes in the top of the salt.

Fill the holes with agriculture grade vinegar and table salt. Should be dead within 6 months. I have used cornmeal with great success. Sort of an organic preen. Glyphosate is very effective at killing. Do we really need it in the food chain? I would rather use gasoline or diesel to control weeds. You are pouring refined hydrocarbon oils, napthalene, toluene and alkylbenzenes onto your soil.

Not to mention that gasoline has benzene in it which is utterly carcinogenic. Diesel is very persistent in the soil and can also move into the water table. That is just as wrong headed as using hydrocarbons. So repeated applications are necessary if using vinegar. The article mentions that it takes several applications for the salt to penetrate into the soil.

That should kill the roots. I can buy Roundup for less than a dollar per gallon and a generic version for even less. If you go to a farm store and not the big box stores. I have an acre of yard with lots of uncultivated areas where weeds like to go. If I used your vinegar mixture, it would break me. I mix it up in 15 gal batches and it takes about two batches to spray all that I need to spray and it has to be 3 or 4 times as weed seeds can lie dormant for years before sprouting.

It most likely is also less expensive to start with. I mix it 1 oz to the gal of water. It kills most weeds and makes all of them sick. Some weeds have a resistance and need to be sprayed a second time.

Using a preemergent, like Preem, will help but it also needs to be repeated. Roger, check the cancer stats in your area. If everyone was using heroin, would you too? Round-up is a toxic soup of poison for people and the environment. Stuff is just bad. Just sharing information, Roundup goes inert in the ground 30 minutes after contact. The amounts that are applied to plants are harmless to animal and humans.

It has to be a much greater dose like drinking concentrate out of the bottle to be toxic. Roundup is not a source to worry about. Therefore, must not be much of a worry, as far as the EPA is concerned. The article I read said it never degraded. Please link your source. Every little bit is extremely toxic dont let them or anyone tell you any diffrent why do you think 1 million dogs a yr get cancer And so many people have cancer..??? Industry owns the EPA and Congress. The stuff is poison, causes cancer and digestive damages.

The 2nd one is how it kills bees. I went with a group of scientists and advocates to DC in June of We have proven time and time again it is not healthy at all. Even at 0. It is contaminated in everything now. Air, water, soil, clothing,medication, vaccines, supplements and food. We must stop using it.

I encourage you before using it again read all of this research and then go into what we showed to the EPA and what we presented in our Congressional Briefing at this link. To have an attitude that is available to everyone and therefore safe is completely wrong. I once took a job in a factory where the welders were having a problem with the steel arching due to its manufacturing process which left oils and other lubricants on the steel, so they got a general labor girl to dip the steel once it was cut to length in vats totes to clean the oils off.

She was reaching in past her elbows to retrieve the pieces. I was out in the back lot one day and asked her what she was doing and told me she was dipping the steel in acetone to remove the oils. Had a pool on the land for 7 years, took it down, weeds grew back in less than a year.

You can even use stones or pavers over the top to camouflage the barrier- it needs to sit long enough to kill the root systems completely. Vinegar method will not penetrate the roots- only new growth.

If you want grass to grow in that area be very careful about using salt- salt will make the land essentially barren- kills both undesired and desired plants. Honestly, if you hand pull the large weeds or use a weed removing tool- it will be the most effective method if your root systems are that strong. Hi Ron: you actually have to add salt to the vinegar to make it work. Next time I did it with the salt in the vinegar.

That is supposedly supposed to kill everything with a residual effect. The first year I did it, yes it was residual. Next year it was not. But it still killed everything. I mean.. Come on. Use some common sense. My house is surrounded by corn grown for silage to feed dairy cows and they use roundup ready seed and spray with roundup. I guess we are all going to die. Can I use the vinegar solution to control both crabgrass and weeds growing in fescue? If not what does work without harming the good grass?

Typically what people think of as crabgrass is actually a thick bladed fescue. This is because some international organizations now believe that glyphosate is a possible carcinogen. If Roundup is, in fact, a carcinogen, then those people who come in close contact with the weed killer or consume food treated with or near this product may have serious cause for concern regarding their health. Monsanto, the company that created Roundup, and other companies with a direct interest in the outcome of the research often commissioned those unpublished studies.

Conversely, the IARC relied heavily upon peer-reviewed studies that were intentionally neutral and not funded by any interested party. Just as there are differences regarding the dangers of Roundup, there are also scientific debates regarding the danger that soil contamination poses to humans over time. Any prolonged or extensive use of glyphosate-containing products such as Roundup should continue to be of serious interest to scientists. Continued research needs to occur regarding both the environmental risks and the risks to humans with respect to this possible carcinogen.

Most research shows that the length of time that Roundup stays active in the soil in many cases is less than one year, but the range depends largely on environmental factors and the amount of the chemical that a person applies in a particular area. A product liability lawyer can help you understand how an attorney may be able to help you with your next legal steps. Roundup manufacturer Monsanto claims the use of their product is safe and does not result in toxic soil.

However, one USDA microbiologist begs to differ. According to Robert Kremer, phosphorus-rich soil can result in glyphosate teaching into the groundwater and contaminating it. Roundup is also believed to poison the helpful microorganisms in the soil. Kremer said the glyphosate leaches into the plants through the roots. How long does it take for Roundup to get to the roots?
