pointsevenout 7 months ago said: RE: Herbacides Most of you know I've just finished planting a vineyard. Now I'm in search of an organic herbicide to keep me from spending all day weeding. I'm not opposed to going with a chemical broad-spectrum herbicide, so I need your help to try to keep me organic.
Preliminary research has identified two herbicide recipes:
4 cups white vinegar 1/4 cup salt 2 teaspoons liquid dishwashing detergent
Combine ingredients and pour into a sprayer and apply to weeds. _______________________________________________________ 1 gallon of 10% vinegar Add 1 ounce orange oil or d-limonene Add 1 tablespoon molasses 1 teaspoon liquid soap or other surfactant (I use Plant Wash) Do not add water
Shake well before each spraying and spot spray weeds. Keep the spray off desirable plants. This spray will injure any plants it touches. This natural spray works best on warm to hot days.
Does anyone have any knowledge or practical application experience with either of these formulas?

All the info I've read so far says that 5% vinegar gives unreliable results.

Think I'll try an experiment first: Buy a gallon of white vinegar from the store. Standard 5% concentration. Freeze it in a wide mouthed container. The water should freeze and the vinegar remain liquid. Remove the ice. Divide the ice in half, then in half again. Discard 3/4 of the ice. Melt remaining 1/4 ice back into the vinegar.
Removing half the ice effectively doubles the vinegar concentration to 10%. Removing half the ice again effectively doubles the vinegar concentration again to 20%.
If it is cost effective, I'll do it this way instead of ordering a bottle. Still have to buy the orange oil.

pointsevenout 6 months, 3 weeks ago said: RE: Herbacides Thirty dollars for the horticultural vinegar after shipping and handling is added in. I'll see what I can get from the grocery store and after conversion to the stronger vinegar formula.
pointsevenout 6 months, 3 weeks ago said: RE: Herbacides I am dubious over the outcome of this experiment because the freezing and boiling point of vinegar and water are so close together.
pointsevenout 6 months, 3 weeks ago said: RE: Herbacides As I suspected. The proportions of water to vinegar did not come out right on the freezing attempt and I have no good way of evaluating the exacting % of vinegar content except by extrapolation. Even if it did, it cost $3/gal 5% vinegar and I would be throwing away 75% of 95% of the contents of the gallon (presumably water) leaving approximately between 25 and 30% of the total gallon of vinegar at a 20% concentration. So it would take about 4 gallons of 5% vinegar to make one gallon of 20% vinegar. Cost would be $12 plus another almost $1for tax. Still to be added into the cost is the orange oil, which I have not priced yet. Might be a good thing to do right now.
Preliminarily the total cost is going to be on par with the internet price before shipping and handling which doubles the internet price. Over the internet I am guaranteed the 20% solution.

One gallon of horticultural vinegar purchased on-line cost $30.60 with orange oil and molasses added per formula. One gallon of home condensed vinegar to 20% with orange oil and molasses added per formula cost $12.60. A significant savings if the home condensed vinegar can be reproduced reliably. One gallon of chemical herbicide, mixed from concentrate, cost $1.50.
I can’t see going down the path of an organic herbicide because of the huge difference in price. I thought maybe it was going to be cheaper than the chemical herbicide. I am disappointedly wrong.
