Biodegradable and Safer Alternative for Commercial Herbicide





Introduction: Biodegradable and Safer Alternative for Commercial Herbicide

With this Instructable we will learn how to make a safer and cheaper alternative to commercial herbicide. The ingredients are very easy to obtain at any supermarket or grocery store. Most of us have them already available at home. 

Step 1: Ingredients

You will need:
  • 1 gallon (3.78 liters) of white vinegar
  • 12 ounces (341.1 grams) approximately of salt for every gallon of vinegar
  • 1 tablespoon, more or less, of dishwashing detergent (biodegradable detergent preferably) will work as a surfactant
Mix and shake the ingredients on a safe plastic container.

Step 2: How to Use the Biodegradable Herbicide

For maximum effect you should spray the solution on a very hot and sunny day over the undesirable plants using a small trigger sprayer or a pump sprayer. Cover the whole plant and roots and watch the weeds go.

Although it took 4 days of watering clover three times a day for 6 days eventually mold grew on the soil and the clover. It may have been very difficult to extract and keep the enzyme stable with my method.

However I have discovered that this selective Pathogenic plant mold if used in terms of dose and then exposed to 1-2% bleach could be used as a tough herbicide that could kill very tough plants like Poison Ivy.

Here are some images of the clover infected by the mold.


At ph 6.0 the solution caaused at 50% the clovers to start to grow. So I have added a 6.66% active enzyme with acetic acid and a bit of sodium acetate at pH of 4.0.

Here are some calculations to get the pH from 14 to 4 with acetic acid.

pH 14.

KOH(aq) + CH3COOH >>> CH3COOK + H20.

HOCl Lets pretend it too small to measure.

When neutralized with sodium thiosulfate pH was 14 means

very little effect.

4g/56.11 g = 0.0712 moles*10 = 0.712 moles per L.

1. Neutralize Lye.....

0.712 m*60 g (Atomic mass of acetic acid) = 42.72 g per L.

Requires 4.3 g Acetic acid.

Now pH is 7.0

Get it to 4.0

1% acetic acid m/v.

pH = -log (H+).

25 g*0.01 = 0.25 g.

0.25g/60g = 0.0042 moles Acetic acid.

Ka = [H+][A]/[HA].

Ka = 1.8*10^-5.

1.8*10^-5 = X2/0.0042 m.

X2 = 7.56*10^-8.

X = 2.749*10^-4.

pH = 3.5

Diluted this goes down a lot.

150 ml total/ 25 ml acetic acid mix * 0.25 g Acetic acid = 1.5 grams Acetic acid required in 150 ml water.

Requires 37.5 ml acetic acid for a total of 100 ml water.

I have done more testing but for me at pH 5 (non diluted) and 6-7 for 25% the enzyme did not prevent growth of clover seed. Also reports say the optional temp is 45-50 degrees at 3-6 pH. At 20 degrees and pH 4 the solution active enzyme is Only at pure strength 16% max.

This solution of enzymes prevents growth of plants safely.

In school the Plamsa is used to peirce cell wall of bacteria and fungi. I have to do a trial and error results to get the enzyme out.


I am attempting again to plasma enhance the effects of mold and generate plasma that may (Key word) penetrate the cell wall structure of the cell. 12 kV 30 ma at 1 degree gives roughly 85 Amps. Here are some images of prep work.


What you are seeing is plasma.

Here are a few prototypes of using high voltage with PI inside a aluminum foil which generates a plasma. It is important that the PI be completely dry with 12,000 volts 30 ma.

Here are some images of results of grtowing pencillium and procedures to help
