Using a little turmeric powder mixed with rice can protect the stored grain from pests
WITH farmers using primitive methods
offood storage that provide easy access
to a variety of pests, the storage scenario
in India is quite depressing at present. In
view ofthis problem, A Thimmaiah and
A Ravishankar of the Indian
Agricultural Research Institute have
come up with a down-to-earth method
for small-scale storage of rice (Kisan
World, Vol 22, No 7).
They suggest that using powdered
turmeric (Curcuma longa), a crop extensively grown in India for its underground rhizomes that find
use in an array of fields After treatment
like spices, cosmetics,
medicines and dyes, stored with turmeric
rice can be protected from powder, rice

mixing of turmeric one year
powder at a concentration
of 2.5 to 3 per cent with rice in jute bags;
before storage is a simple and efficient
method to manage pests. After treatment with turmeric powder, rice filled
jute bags are stacked on a wooden plank
for storage which ensures protection
against pests for 1 year.
Currently, synthetic insecticides and
fumigation are widely used to manage
Storage pests. But it has been found
that insects develop resistance
against the chemicals used, rendering them ineffective. Also, the toxic
residues are left in the grains, threatening human health.
"It is time that the
potentialities of turmeric
are fully exploited for the
benefit of humankind," says A Ravishankar.
for a Besides being cheap and
economical, this method
is "simple, effective,
nature-friendly and safe",
adds Ravishankar.
