Facts about JADAM sulfur
Taking advantage of the prevailing popularity of sulfur, some people ad-
vertise that you have to use “detoxiied” sulfur. is is a cheap scam, a
fraud. ese people say that if you use “untreated” sulfur instead of “detoxi-
ied” sulfur, then the poison in the sulfur will ruin your crops. I would not
even mention this problem if companies sold their product at a reasonable
price but they in fact are hoodwinking many farmers and selling at extrava-
Spray bottle with JS di-
luted 10 times with
water. It is effective
against athlete’s feet
and eczema. Careful if
you have sensitive skin.

gant prices. 
Let’s think scientiically. If something
is “detoxiied” that means it had some
toxin that was removed by a treatment
process. en please tell me what toxins
were held in the sulfur in the irst place
when the purity of sulfur we use is
99.9%? ese people should be able to
say what toxins were there originally and
how much of them were removed
through “detoxiication.” However, all
they ever say is that their end-product
sulfur does not contain any lead (Pb),
cadmium (Cd), chrome (Cr) and arsenic
(As). ey stress that to remove these
toxins, they have to detoxify sulfur. 
e four heavy metal substances that
they reference are not found in the
99.9% pure sulfur in the irst place.
Nothing was detoxed because there were
no toxins to detox. e sulfur JADAM
uses is very cheap; about 1 dollar for 1

kg (2.2 lb). To further elaborate, I have provided a table of substance analy-
sis for the sulfur we use. Lead, cadmium, and arsenic were not found
whereas a very small amount of chrome [0.04 ppm (mg•kg-1)] was de-
tected but at a level 1/2,000
th
of the legal standard. is is negligible; it is
even smaller than heavy metal detected in other liquid fertilizers. JS does
not have to be always made in 100 L (26 gal). You can increase or decrease
the size while keeping the ratios. For gardening purposes, use 1/10
th
scale. 
Water has to be clear after mixing. Soft water,
when mixed with JWA and JS, will remain
clear and have good foam. This indicates a
good quality pesticide. Bubbles are the key in
pesticide
Clotting means problem. If water is not good,
clotting can happen. You must change to soft
water. Rainwater is typical soft water. If you use
this clotted pesticide, you will have bad results –
and many blocked nozzles.

If initial water is too small, intense heat will solidify
sulfur. Once solidified, it will not melt. 
•
For 500 L (132 gal), use 0.5-2 L (0.13-0.53 gal) in growing season, 5 L
(1.3 gal) in winter pest control. For fog machines, use 0.1 L (0.03 gal) for
17 L (4.5 gal). 
•
Can be applied to all crops. 
•
No expiry date.
•
Costs 50 cents per liter (0.26 gal). 
•
JS is germicide against diseases. If used in strong diluion, it can also
kill insects. 
•
Apply in early morning or at sunset. Avoid hot imes of the day. 
•
Does not damage the plasic sheet or the steel pipes of the greenhouse. 
•
Always do mixture test and concentraion test when you want to use
JS with other commercial chemical pesicides. Do not use coninuously;
use only when in need to combat diseases. 
•
NaOH 
: It is beter to use products that come in forms larger than powder
(like flakes). If the purity is very high, like 100 percent, you might need to re-
duce the amount slightly compared to when you are using 98 percent purity. 
•
Sulfur
: Some sulfur products produce some black debris and oil film on top
of the soluion ater the making is finished. In this case, remove the paricles
and oil layer, and then use.
