Abstract
An application was developed to project UHF electromagnetic fields into soils containing seeds. The unconfined field (2450±20 Mhz) was effective in killing seeds in the soil. At a fixed energy level the toxicity of the field to wheat (Triticum aestivum L.) and radish (Raphanus sativus L.) was constant or slightly increased as the time of exposure was decreased. Thus, the energy requirement for a given level of toxicity can be met by substituting increased power levels for time of exposure in the range of 100 and 1200 watts.
