The spring is a big time for slugs and snails. I found this out to my cost last year.
This year I noticed earlier and decided to bring the ruckus sooner. I don’t own
ducks (pace
Mollison) and therefore need to be the predator myself.

Youngsang Cho is a man after my own heart. Undergoing four
NDEs and living with “the realization that my death was always near” Cho, a
brilliant chemist, decided to share rather than claim exclusive rights to his
knowledge. He writes, “I could have gained enormous wealth through patents, but
I gave up for the greater good.” This decision was influenced by his passion
for both Jesus Christ and Karl Marx. Cho describes having an apocalyptic vision
of a capitalist society and thus embarked “on a long journey to liberate
agricultural technology from monopoly capital, by following the spiritual
ideals of two great teachers.” He is a bonafide genius.
I’ve been studying Cho’s JADAM
Organic Farming Technology and decided to make the assault on the Phylum
Mollusca the first part of my investigation into it. Credit must also go to Garden Like A Viking for
his adaptation of Cho’s recipe which includes adding garlic.

First blend two cloves of garlic with a jam jar of water.

Let the resulting garlic juice sit for half an hour.

Make
JADAM wetting agent. This is a soap. Its application means that there’s no
surface tension on what you spray. An application coats leaves evenly.
As tempting as it was to make this JWA myself – it simply
wasn’t economical to buy huge catering buckets, a paint-stirrer, gallons of
purified water, rapeseed oil, and source Potassium Hydroxide.
If I had a market garden, maybe! But not for my tiny roof
garden. So, I bought this wetting agent off Dr Forest on eBay. I needed
roughly a cap full of this.

And this is Sodium Hydroxide. Of which I needed only a
teaspoon. Now for the contentious part… Mine is not a truly organic garden. I
have, for instance, purchased compost which wasn’t organic. It would also be
entirely pointless to get it certified. However, I have generally abided by the
spirit of organic growing. Up to this point, a few years in, I haven’t used any
chemical fertiliser, herbicide, or pesticide.
JADAM is, they claim, made entirely with chemicals which are
USDA Organic approved. That’s to say they are supposed to be approved under
American Organic regulations.
In the JADAM Organic Farming book one can find tables from
the USDA which specify that these two chemicals are “Inerts of Minimal
Concern.” Summarising the documents below, you’re only prohibited from using
NaOH and KOH to peel fruit and vegetables. KOH you can even use to peel
peaches.


JADAM also have on their
website a document written to them which clarifies that these chemicals
abide by USDA Organic regulations:

However, neither Potassium Hydroxide nor Sodium Hydroxide
are chemicals
approved by the UK’s Soil Association. Furthermore, it might need to be
pointed out that these USDA Organic regulations are the same ones which allow
Hydroponic growing and Concentrated animal feeding operations (CAFOs) to be
certified as organic.
Gotta be straight with you, I don’t think this is what Sir
Albert and Lady Eve had in mind. There are also rumblings from American farmers
which one can read in the comments box:

Did this stop me? In fact, no. Because I detest snails and
slugs, because Potassium Hydroxide is just an ingredient of soap which decays
in the process of its manufacture, and Sodium Hydroxide breaks down relatively
quickly into salts which are, broadly-speaking, positive amendments to the
soil. I don’t need to worry about losing my organic certification, because I’m
not certified. JADAM is fascinating and I was very curious to try.

All these ingredients: the garlic, water, JWA, and Caustic
Soda I mixed up into roughly 2 litres of juice.

And in the dead of night (because you can’t spray this stuff
during the day) I sprayed my plants. This is me spraying the Yarrow I got from
Anthroposophy HQ, Emerson College at Forest Row. For some reason the slugs love
the Yarrow. Rudolf Steiner will be turning in his grave – preferring, probably,
that I would incinerate a single slug and dilute and spray its ashes
everywhere. I may yet try that…
I followed this process on the 26th and 27th of March and
sprayed for two nights in what has been peak slug era. What did alarm me was
that on the first night, being a little gung ho, I got the spray on my hands. I
think I was carried away with all the hype of how harmless this stuff was. I
ended up getting it on my arms and face.
It was not only very irritating but also slightly painful.
Here’s a
post by the Okanagan Okanogan blog which goes into a heavy-critique of
JADAM and the effects of NaOH. Not deterred I took more precautions the second
night, was like really careful, and still managed to get some small
amount vapour in one of my eyes. This was sore and, because it was in my eye,
also a bit worrying. If I sprayed again, which to be honest is unlikely, I
would wear goggles, not just glasses. Even the odour of the garlic has lingered
somewhat unpleasantly…
The following night, the 28th of March I found the slugs and
snails still very busy. Was their activity less than it would otherwise have
been? It’s impossible to tell, but to be honest I was disappointed. I think if
one was trying to subdue slugs and snails on a 3 acre market garden this might
be an excellent solution – but I don’t think it was appropriate to my
situation.
Henceforth I am going to return to my tried-and-tested
technique of going out after 10pm, picking the tiny fuckers off with tongs and
dumping them in very strong brine. This being my own unpatented method and one
most suitable to my twenty square metres.
This, however, is not the end of my JADAM experiments. There
are a further two more to come.
