4. Important points in using natural pesicide
If you have already made yourself microorganisms, liquid fertilizers and
you go on to succeed making natural pesticides, you will be excited. But al-
ways take more care when things look good. Natural pesticides can cause con-
centration problems (where too strong a solution can harm the plants or the
soil) or sometimes cause trouble with a particular plant. Remember that good
and bad are one; there is nothing that is always good. The greatest care should
be given to this concentration problem. JADAM sulfur, JADAM wetting
agent and JADAM herb solution can all cause concentration problem when
applied too strong. JADAM provides the basic guideline but there are so
many variables taking into account the differences in season, environment,
particular crop, weather, etc. that eventually it is
up to the individual farmer to verify the safety.
Whenever you have made a JNP, always test it in a
small area before spraying it in your whole field.
This is particularly important if you are going to
use natural pesticide together with chemical pesti-
cide. Farmers themselves are responsible for any
concentration problems.
Good water is extremely important
Only when the pesticide “wets” the target fully,
will it be able to control pests and leave no marks on
the fruits or leaves. Good wetting property also re-
duces concentration stress. You must take care to wet
the target fully and evenly so as not to leave marks;
this is important in producing clean, high quality
Pamphlet and JWA sample pro-
vided by JADAM. Perform a water
test with JWA.

products. e quality of water plays
an important role in determining
the wetting power of the pesticide.
You must use good water.
JADAM
wetting agent is the pri-
mary
ingredient in natural pesti-
cide. JWA is profoundly affected by
the quality of water.
Just as soap
does
not produce bubbles in hard
water, JWA will perform poorly
when mixed in hard water. Hard
water is water with high content
of Ca, Mg and Fe. You must do a
prior water test to make sure that
the water you are using for pesti-
cide is soft. You can do a simple
test with JWA. Put in a few drops
of JWA in water, the water will
keep clear if it is soft water. It will
produce lots of foam when shaken.
e water on the left has lots of
foams and keeps clear. As you go
to the right, water becomes
murky like milk. Water on far
right produced no foam at all.
Water on far left is optimum for use as pesticide. Use this water for making
JWAs, pesticides, boiling herbs and culturing microbes. Chemical pesticides
use synthetic wetting agent which are less affected by water but they still pro-
duce little foam in hard water. eir wetting power too is affected by water
