6. How to do natural pesicide research
I have said that you must become a pesticide expert. en you must know how
to study, experiment and research. I will introduce an easy yet effective method.
We don’t promote the use of high-tech equipment because that just is not afford-
able for most farmers. e method I am about to show you is quite unreined but
it gives very practical results. What I suggest is the “cup” method. Use cups to
test; it looks pretty shabby but returns practical results. Let’s irst study natural
germicide. We know that there is plenty of information on what natural sub-
stances have a germicidal effect. e problem is checking for their efficacy. ere
Tools used in JADAM natural pesticide lab. Just add some cups and you are
ready. Print a business card with your title as “president of natural pesticide insti-
tute” – nothing wrong about that! Simple tools, cups, dishes from the kitchen is all
you need to study pesticide and germicide and apply it in your farming. It costs 50
dollars to set up your lab.

are hundreds of different pathogens
and we surely do not have the time
and means to test them individually.
We know we cannot separate each
microorganism; so we mix them all
and ind out if our germicide kills
them all. Leaf mold holds millions of
microorganisms in it. Collect it and
mix it in water. Pour the same
amount of this bacteria-holding
water into many cups. Also add the
same amount of molasses to feed the
microorganisms. en add germi-
cide starting from zero in incremen-
tal quantities in each cup. If the
pesticide effectively inhibits the
growth of microorganisms (which
can be translated into pathogens)
you will see less foam. You can ind
out exactly which germicide is effec-
tive and at what dilution rate. Com-
pare the performance of different
germicide ingredients. You can also
know how long the effect lasts. is
test will only take a few days. Apply
this to your ields and you will ind
that the results do not vary greatly. You do not need to stay as a follower of
JADAM; with your own methodology, you can surpass JADAM. Go for it!
Now, for pests. ere is already an abundance of information on what natural
Add water in cups; add same amount of molasses in
each cup; add a few drops of leaf mold water to inoc-
ulate the microbes. Cup on left has not added any
germicide. Cups on right have been added with vary-
ing dose of germicide.
After 2-3 days, you can visibly check the effect of the
germicide. The cup on left has been allowed uninhib-
ited multiply of microorganisms; so it serves as a cri-
terion. Bubbles on surface evidence the propagation
of microbes. If there are no bubbles at all, the growth
of microorganisms has been inhibited completely.
Check the dilution ratio when it becomes effective.

JS made without heating has sulfur content of 25%.
To check its germicidal effect, we have added differ-
ent dilution ratios of JS to cups holding water + mo-
lasses + leaf mold water. Cup of top left had no JS
added; cups to the right have increasing dose of JS.
These cups hold 0.5 L (1.1 lb) so are a 1/1000 model
of 500 L (132 gal).
After 2-3 days, you can check the propagation of mi-
crobes feeding on the molasses with the vigor of the
bubbles. Experiment gives us data that 1.5 cc (0.05
fl oz) and 2 cc (0.07 fl oz) of JS made no difference.
Observe for over 10 days to see the effect of JS on a
prolonged period. We have checked that 1.5 L (0.4
gal) of JS in 500 L (132 gal) solution can perfectly in-
hibit microbial growth.
These “petri dishes” are commonly used in lab mi-
crobiology researches. In each of them, drop in tens
of aphids and spray with natural insecticide, close lid.
You can observe how aphids react to different doses
of pesticide.
If the pest has a larger body, such as the larvae of
cabbage white butterfly, tobacco moths and beet
armyworm, use larger dish. Different natural ingredi-
ents have different effect on the pests. Some make
their heads drop, some completely overturn them.
The results acquired at the lab are almost precisely
repeated on the fields.

substances have pesticide properties. JADAM has long posted on its website in-
formation about what plants have those kind of abilities. Our database could cer-
tainly be one of the largest collections of information about pest-repelling plants.
Try the above method as shown in the pictures and you will see for yourself the
effects of natural pesticide. You will also learn what percentage of pests dies and
how much time it takes. e great thing about this experiment is that its results
are not much different in the ields. Modern science as we know it is truly as-
tounding; however, the founders of it all began on desks and laboratories not
much different from ours. JADAM’s vision is that all the farmers study, apply and
develop their methods and share what they ind.
This simple experiment tests the repel-
lant effect. See how the stinkbugs run
away from cosmos flower. (Mr. Geol
Yu, Jadam member)
After checking the effectiveness of
natural pesticide, test in different dilu-
tions in the fields. Prepare bottles that
contain solutions that are twice, three-
times, four-times stronger than the
standard usage. Find out at which di-
lution concentration problem is
caused.
