Abstract

The concentration of N,N-dimethyl-2,2-diphenylacetamide (diphenamid) required to cause 50% growth inhibition (I50) of the shoots or roots in soil, or the roots in a bioassay, was determined for several species. of the plants tested, grasses were the most sensitive, while Solanaceae were among the most tolerant to diphenamid. Based on shoot inhibition, the sensitivity difference between the sensitive foxtail millet (Setaria italica L.) and the tolerant pepper (Capsicum frutescens L.) was 150 fold. Highly significant correlations among the I50 values indicate that any of the three methods would be satisfactory for measuring the sensitivity of species to diphenamid.
