The ovicidal action of mercury salts applied to the soil is due to metallic mercury in the gaseous state. The presence of mercury in the atmosphere over mixtures of soil and mercury salts has been repeatedly demonstrated. The concentration of mercury vapor was always found to correlate with the mortality of insect eggs exposed to such atmospheres. Factors affecting the reduction of mercury salts to metallic mercury were found to be (a) soil organic matter, (b) moisture, (c) soil pH, and (d) temperature.
