How to make an organic pesticide (EM5)

Another best application of effective microorganism (EM) technology is to make a non-chemical pesticide that completes its use in green technology. This organic pest repellant is also known as EM5 and it is non toxic. The EM application is usually in diluted concentration (1 in 500-1.000 parts) and do the job by providing a kind of barrier to plants from insect attacks.

Materials used in making EM5 may vary from one location to another, depending on the local availability and price of the materials. A standard set of materials and quantities generally used in making EM5 is given below. For more persistent insects, it is recommended to include organic materials having a strong medicinal properties such as garlic, aloe, hot peppers, neem leaves, etc. When such materials are used, it is best to chop or mash them with a mixer to increase their surface area and for a perfect mixing with other used substances.

Here is how to make organic pesticide (EM5)

Materials needed:

1. Water (600 ml). Use well water as tap water is usually chlorinated
2. Molasses (100 ml)
3. Vinegar (100 ml). 
4. Distilled spirit (100 ml). You can use whiskey or ethyl alcohol as an alternative
5. EM1 (100 ml)

Procedure:

1. Blend the molasses with water, make sure that it is completely dissolved. Use warm water for quick dilution of molasses.
2. Add vinegar and distilled spirit, followed by EM1.
3. Pour the mixed solution into a plastic container which can be shut tightly (A glass container should not be used, as gas production will be monitored from changes of the container). Remove excess air in the container to maintain anaerobic conditions.
4. Store it in a warm place (20-35 °C), away from direct sunlight.
5. When container is expanded by the fermented gas, loosen the cap of the container to release gas. Shut it tightly again.

EM5 making is complete when no more gas is produced and the smell of the solution has produced a sweet smell. The EM should be used within 3 months after produced. Storage is in cool dry place with a homogen temperature. Do not expose it to direct sunlight nor place it in a refrigerator.
