Smile Vinegar new cost effective weed control for Organic Farmers.

I read about a study the USDA did last year, then tried a 5 percent store bought vinegar to test last season. Verry impressed, & going to buy the stronger product this season.

We were surprised that the weak solution, killed as much as 80 percent of weeds on our inside Rabbit fences. Our best time of day to apply, was just before dark so the liquid had a chance to absorb.

I wonder how much of it the dogs will lick off of the plants, and if it will hurt them. One of my dogs loves to roll on plants that have been freshly sprayed with RoundUp.

vinegar and citric acid

I was astounished to read your question concerning the toxidity of the vinegar...if it would harm your dog when you apparently allow your dog to be exposed to a known carcinogen, Round-up. I was surprised that you would ask Marturo for information which he researched and supplied you with and then make such a statement. You have a page about your dogs on your web site that one would get the impression that you would not do anything to hurt them.

I guess you are so busy trying to answer so many questions on DIY that you forgot to respond in a manner which would show appreciation for assistance and time spent to help another. There are some who are caring about their pet's health and that of their own family and environment who would never allow them to go through any area which has been sprayed with any type of herbicide, but no one is telling you what form of herbicide to use. .

I resent your blowing in here with an ad hominem attack on me with your unsubstantiated claims and allegations.

If you have some facts, trot them out. Roundup is not a known carcinogen. Its components Glyphosate and Isopropylamine salt are not known carcinogens. So stop waving the hysteria flag.

These forums are a place for people to ask questions and receive answers, some of which require time to research. People reserve the right not to answer questions. I appreciate the time and energy that goes into all the work by responding in kind.

I asked about the toxicitiy of the 20% vinegar, because he has experience in using vinegar for this purpose. The 20% vinegar is 4 times stronger than household vinegar. There is a good chance that this chemical needs to be allowed to dry before the dogs can go out there. You can rest assured that I will be doing my own research, in any event.

I diligently maintain a safe environment for my dogs. Hazardous chemicals are always applied in a safe manner. They receive regular checkups at the vet; eat a proper, monitored diet; and live and sleep in a safe, controlled area.

I am offended by your thinly veiled implication that I don't care about the health of my pets, my family, or the environment.

I asked the question about the vinegar to stimulate discussion about alternative means of weed control. I answer questions because people ask them, I assume, in earnest. It is my profession to provide assistance to people.

I am well aware of the amount of time it takes to research and formulate responses to many of the questions asked. For instance, Roundup is a herbicide, not an insecticide.

Let the vinegar dry

It is clear from the MSDS for the 20% vinegar that it must be allowed to dry before animal contact is allowed. From the MSDS:

INHALATION: Threshold Limit value: 10 PPM

Short Term Exposure Limit: 15 PPM for 15 minutes

Odor Threshold: 0.037 – 0.15 PPM

Inhalation of vapors can cause irritation to respiratory tract. Avoid inhalation.

SKIN CONTACT: Contact may cause mild injury and burns from vinegars of 11% acetic acid and greater. Dilute solutions may cause dermatitis in some individuals.

EYE CONTACT: May cause severe burns and permanent corneal injury from concentrated vinegars. May be followed by blindness. High vapor concentrations may result in conjunctivitis.

INGESTION: Concentrated vinegars may cause pain, irritation and burns in mouth, gullet and stomach.

REPRODUCTIVE HAZARDS: Not a reproductive hazard.


EYES: Flush immediately and thoroughly with water.

SKIN: Flush immediately and thoroughly with water.

INHALATION: If vapors are inhaled extensively, exposed person should be removed to fresh air immediately.

INGESTION: If swallowed, water should be consumed to dilute. Do not induce vomiting. Do not give emetics or baking soda. Call a physician.
