Summary The influence of soil organic matter and soil moisture content on the bioactivity of dinitramine was investigated in laboratory and greenhouse experiments. Adsorption increased directly with soil organic matter content and inversely with soil moisture content. Phytotoxicity to soybean ( Glycine max (L.) Merr.) was inversely related to soil organic matter content while the toxicity of the herbicide to French bean ( Phaseolus vulgaris L.) was directly related to the soil moisture content from 20 to 100% of field capacity. Dinitramine is active in the vapour phase, and volatilization and bioactivity were directly related to soil moisture content and inversely related to soil organic matter content. Variability in the performance of soil incorporated dinitramine in the field seems very likely, depending as it does on soil moisture content and soil organic matter content.
