The Cereals, pulses, oilseeds etc. are very important products for storage. A safe storage place must be provided for the grain produced until it is needed for consumption and multiplication purposes. Since grain production is seasonal, and consumption is continuous, safe storage must maintain grain quality and quantity. This means that grains have to be protected from weather, molds and other microorganisms, moisture, destructively huge temperatures, insects, rodents, birds, objectionable odors and contamination, and from unauthorized distribution. The protection of crops, stored food grains and pest control in the public health sector continues to place heavy reliance upon the use of chemicals. The history of pesticide development has been instructive to us in terms of benefits derived as well as the hazards, which accompany indiscriminate use of these poisons. The volatile substances obtained from higher plants have proved their usefulness in controlling biodetioration as they form a vast cornucopia of defence chemicals, toxicant and antimicrobial agents. In this communication bioactivity of leaf extracts from Hyptis suaveolens was tested against Aspergillus flavus and Aspergillus parasiticus.
