[Digestion] Info request on "Pest Repellent property of dilute slurry"

Thu May 16 11:34:31 CDT 2013

Dear List,

Reminds me of a low cost  experiment I did some years ago on a potential
organic fly repellent. Left a bucket of fermenting fruit in the lab until a
lot of fruit flies were present.  Stuck a stick with sides 1" X 1" square in
the center of the bucket and the flies would land on it. Painted two sides
with the repellent, waited and then counted flies. Shook the stick then
waited for them to land again and counted. Compared painted sides to
non-painted sides. For my experiment there was no difference.

Dear Chanakya,

You may find this attachment interesting. In Cambodia some farmers prepare
their own pesticide by mixing bio-slurry with a number of plants (tobacco,
chili etc), then let it ferment for a couple of weeks before applying it as
botanical herbicide. Farmers report that it works just as good or even
better than chemical pesticides.

However, most farmers just use bio-slurry directly without this treatment.
Even so, farmers report it reduces pests. In our latest monitoring survey
among 165 randomly selected households we asked what the impact of applying
bio-slurry was on the number of pests, 8% said no difference, 12% said no
pests anymore and 76% reported experiencing less pests after applying
bio-slurry. This clearly shows that bio-slurry is much more than a
fertilizer.

Hope this is of use,

Cheers,

Eric

Dear List users,
I would be grateful if any of you could forward me any information of
'personal experience' or 'published information' on "pest repellent"
properties of dilute or filtered biogas slurry on agricultural and
horticultural crops.  This will be used to convince a few policy makers to
push the case of Biogas plants.
Regards
Chanakya
