SURVEY OF INDIGENOUS TECHNOLOGIES AND EVALUATION OF BOTANICALS AGAINST MAJOR STORAGE PESTS
Abstract
"The survey of indigenous storage technologies available in Hyderabad Kamataka
(Gulbarga and Bidar districts) and the effect of few promising botanicals against two major
stored grain pests on sorghum and chickpea under laboratory conditions were carried out at
Agiicuiluiai College Raichur, Karnataka during 2002-03.
Among the storage practices followed in the Hyderabad Kamataka region for cereals
and pulses, sim drying was the predominant practice in Gulbarga and Bidar districts. The
predominnnt storage structures used for storing cereals was gunny bags followed by hagevii
and gunny bags for pulses.
The sweet flag and malathion were found equally effective in minimum multiplication
of !)olii Sitoplulus oiyznc and Callosohrucluis chincnsis on sorghum (2.50 and 1.00 adults/100
g of seed sample) and chickpea (1.50 and 1.00 adults/100 g of seed sample) respectively in the
laboratory. Studies on seed mixing and storing along with various botanicals revealed that
malathion and sweet Hag were found significantly superior up to 60 days. Botanical powders
when dusted over cloth bags , the population build up was not noticed in malathion and sweet
Hag treated bags in the beginning , later (after 60 days) incidence was noticed. The minimum
seed d;iniage was in malathion, followed by sweet flag rhizome powder on sorghum and
custard apple seed powder and sweet flag rhizome powder on chickpea. The germination was
unaffected in these treatments in both seed ini.xing and dusting."
