Time-lapse cine photography was used to measure at 10-min. intervals over 72 h the growth rate of pea and barley roots during separate exposure of the shoot + seed, root or entire seedling to 8 herbicides. Times for commencement of root inhibition were determined at exposure to concns. causing 50% inhibition in 72 h. Root growth rate was normal in both species during shoot + seed treatment.
