Abstract
Infrared radiation (IR) has been shown to effectively dry grain while eliminating stored-product insects. Little has been done to examine IR’s effect on rice germination or insect development. Two studies were conducted using XL745 (hybrid) and CL152 (pureline) rice cultivars dried with three IR intensities (2.15, 2.83, and 10.84 kW/m2). Control samples were dried in an environmental chamber (0 kW/m2). Rice was germinated for 14 days. An IR intensity of 10.84 kW/m2 reduced germination, shoot and primary root lengths compared to lower intensities. Lesser grain borers (LGB), Rhyzopertha dominica (F.), were placed on treated rough and brown rice for 50 days. Brown rice had more progeny develop and kernel damage. Drying rice in a single layer, (initial moisture content of approx. 20% wet basis) with an IR intensity of 10.84 kW/m2 for 7 s to 60°C, resulted in more LGB development and kernel damage, and is therefore not recommended.
