Description: The deterioration of stored cereals and oilseeds, caused by fungi, insects, and mites, is an economic problem in western Canada. In years such as 1968-1969, with damp grain harvests, 55% of the primary grain elevators in the prairie provinces re ported grain spoilage (Sinha 1972). In a questionnaire survey of 2919 grain elevator managers, who were responsible for taking deliveries of farm-stored grain in 1970-1971, reports were made of 11 289 hot spots on farms and 929 in elevators and 12 956 moldy grain bulks on farms and 570 in elevators (Sinha 1973). Systems presently available to monitor deterioration of stored bulk grain on farms and elevators take point measurements of temperature. Because the thermal diffusivity of grain is low, temperature must be measured within 0.5 m of an active spoil age spot to detect deterioration (Sinha and Wallace 1965). Spoilage is not necessarily indicated by the measurement of grain temperatures that are well above the ambient temperature. The temperature of dry, undeteriorated wheat at the center of a 6-m-diameter bin in Winnipeg can be above 25
