Jadam organic Farming & Gardening : The Way to Ultra-Low-Cost Agriculture, Make All-Natural Fertilizer, Pesticide and Microorganism Inputs Yourself

7. JADAM weing agent (JWA)
JWA is also emulsiier and surfactant. JWA is the most important mate-
rial in pesticide because it is critical in coating, wetting and delivering the
pesticide into the target. Without JWA, you cannot make pesticide. It only
costs 50 cents to make 1 L (33.8 l oz). e amount of JWA you get by fol-
lowing below instructions is enough to be used for around 30 times (di-
luted in water to make pesticide of 500 L or 132 gal). JWA can be used
with commercial organic or chemical pesticides; but always do a mixture
test and concentration test before use. JWA can replace machine oil or syn-
thetic wetting agent. Developed by Youngsang Cho.
Prepare a 110 L (29 gal) container that is heat-resistant. Make sure it is
clean. Exactly measure and pour in 2.5 kg (0.66 gal) of water; 3.2 kg (7.05
lb) of caustic potash; close lid; and melt it by rolling the container slanted on
its side. e water must be soft water in which JWA dissolves clearly. (Test
with JWA)
Add 18 L (4.76 gal) of canola oil; mix with electric drill until it becomes
like thin mayonnaise. It will take around 10 minutes (longer in summer). Be
careful of liquid splashing. Use machine; do not mix manually.
Close lid and let sit for 3 days; it will harden like butter. If it does not
harden, or if its layers are separated, use drill to mix again until it becomes
like thin mayo. In winter, do it in a warm place. 
Add 20 L (5.3 gal) of water; use electric drill to take lumps off the con-
tainer wall. Do not over mix with drill or else it will become like white cream.
Add 60 L (15.9 gal) of water. Use a clean long stick to manually stir; stir
thoroughly including the bottom. It will melt slowly for 24 hours and will
be completed. If you make it in a cold place, lumps tend to sink down, and
melting into water can be slow. It is important to use clean tools (drill, con-
tainer, stick, etc.).
Store in tight-sealed container. It has no expiration date.
Mix 3-15 L (0.8-4 gal) with water to make 500 L (132 gal).

Natural Pesticides

To make JNP you basically need four ingredients: JADAM wetting
agent, JADAM sulfur, JADAM herb solution and JADAM microorganism
solution. Mixing them in different proportions produces different types of
pesticide. It can become insecticide or germicide or both. e most impor-
tant of all is deinitely JWA – without it there can be no pesticide. Increas-
ing JWA will make the pesticide stronger. JWA increases the coating and
penetration of pesticide substance into the target. Using JWA alone diluted
in water is effective in controlling aphids and mites in early stage. Pests do
not develop resistance against its repeated use. JWA becomes nutrients for
crops; it is moderately effective in improving color and promoting maturity.
Use soft water to avoid marks on plants and damaging white powdery coat-
ing of certain fruits. Neem oil is quite popular; touted as effective against
over 400 pests and diseases. JWA is just as effective. Compared to buying
Neem oil, if you make JWA, the cost will be 1/100. 
e basic principle of making JADAM wetting agent is the same as
making soap out of natural oil. ere are many different methods for mak-
ing natural soap that are readily available. I did research for a long time to
develop the easiest method. Widely known method of making soap is to
mix water with caustic potash and adjust its temperature; mix with natural
oil that also had its temperature adjusted. en you adjust the pH; add
some more substances for aroma; use electric mixer for 3-4 hours; let sit for
a few weeks; then melt in water. Water, caustic potash and other ingredients
need to be added in different proportions every time. If you actually try
making this, it is very difficult. As I repeated this, slowly something dawned
upon me. ‘Hey, maybe it was somebody’s intention to make this difficult
after all.’ If people try to make natural soap for themselves but soon are ex-
hausted; then they will resort to buying natural soap. 
is complicated method of making soap could not be used in farming. I
tried to ind a radically easier method. My goal was to making it with no
heating, in only 10 minutes of mixing and in 3 days of sitting rather than a
few weeks. I completely ignored the temperature requirements. I continued
experimenting with different amounts and proportions of water, caustic
potash and natural oil. After many experiments, I inally found the magic

ratio. No heating, only 10 minutes to make. I named this JADAM wetting
agent. is probably is the easiest method in the world in making natural
liquid soap. e invention of JWA was a complete breakthrough; it opened
wide the world of homemade natural pesticides. 
e awesome thing about JWA is that it is just like natural soap; 99.9%
biodegrades in 5 days when released into the environment. It causes almost
zero soil contamination. JWA is very sensitive to water quality. If you use
hard water (with high Ca, Mg, Fe), then JWA will be not effective or only
marginally effective. You must use soft water; both in making JWA and in
mixing JWA to make pesticide. If only hard water is available, use water
softener. e reason why we mostly use canola oil instead of soybean oil is
because it has a better wetting power. e problem is that most canola and
soybean oils are genetically modiied (GMO). In Korea, there is no law reg-
ulating GMO in natural oil. To avoid using GMO, you can use non-GMO
canola oil or sunlower oil, olive oil, grapeseed oil, etc.
