1. What is meant by Effective Microorganisms (EM)?

E.M. is an abbreviation for Effective Microorganisms

Microorganisms are tiny units of life that are too small to be seen with the naked eye and they exist everywhere in nature. Microorganisms are crucial for maintaining the ecological balance. They carry out chemical processes that make it possible for all other organisms including humans to live. There are friendly guys of the microbial worlds known as beneficial microorganisms and a not so friendly group called pathogens that are
 harmful and capable of producing disease, decay and pollution.

EM origin

In 1982 Dr.Higa at the University of Ryukyus, Okinawa Japan, discovered a specific group of naturally occurring beneficial microorganisms with an amazing ability to revive, restore, and preserve. He named this group E.M. (Effective microorganisms).

Using EM to make an Insect Repellent

This mix will make a non-toxic chemical free insect repellent. It can be used to prevent pest and disease problems in the garden. It acts by creating a barrier around the plant thereby protecting it from insects. The mix can be enhanced by including garlic, hot peppers or aloe vera . These are chopped or mashed prior to adding to the mix.


Warm water (chlorine free ) 

300 ml

50 ml

Natural vinegar
50 ml

Whiskey or ethyl alcohol
50 ml

EM liquid concentrate
50 ml

Select a suitable sized container for mixing, some plastic bottles with caps for storage and a funnel. Add the molasses to the warm water and stir till thoroughly mixed. Then add the vinegar, whiskey and EM concentrate. Pour the mix into the plastic bottles and add small quantities of chopped garlic etc. Seal as tightly as possible and leave in a warm dark place. Release any gas produced at least twice daily by releasing the cap. The EM is ready for use when the production of gas has stopped and the product has a sweet fruity smell. The mix can be stored in a dark cool place which has a uniform temperature for up to 3 months. If garlic extract has been used, filter this out before storage. Do not store in the refrigerator.

Using EM insect repellent mix

Dilute 20 mls of the mix in 2 litres of clean water in a sprayer and spray enough of the mix to wet the crop. Spraying can begin from seed germination or plant establishment and before pests and diseases can be seen. If an attack occurs use up to 30 mls of solution in 2 litres of water Spray weekly either in the morning or after heavy rains for best results.

EM the natural product

•EM is the trade mark used to identify this particular mixture of beneficial organisms

•E.M. is a combined culture of aerobic microorganisms (requiring oxygen to survive) and anaerobic (requires no oxygen to survive) that co-exist together to the mutual advantage of both (symbiosis).

•E.M combines with the existing microorganisms within the soil. They work together to build a healthy living soil.

•E.M is not toxic or pathogenic and is safe for humans, animals and the environment
