The growth of crabgrass ( Digitaria ssp.) and barley ( Hordeum vulgare ) seedlings was susceptible to injury by siduron (1‐2(methylcyclohexyl)‐3‐phenylurea). In both species, root growth was inhibited more than shoot growth and if a functional root system was developed before coming into contact with siduron the plant survived. Kinetin partially overcame the effect of siduron on root growth and increased root length and the number of cells undergoing mitosis per root tip. The effect of siduron seems specific to cell division.
