The effects of varying concentrations and duration of fluazifop-butyl (+-)-butyl 2-[4[[(5-trifluoromethyl)-2-pyridinyl] oxy] phenoxy] propanoate treatment on cell division, cell enlargement, and protein synthesis were studied. Oat (Avena sativa L.) were treated from 0 to 48 hr with concentration ranging from 1 x 10(-6)M to 1 x 10(-3)M of fluazifop-butyl in the cell division study. There was a significant reduction in the mitotic indices of oat roots treated with 1 x 10(-4)M after 6 hr. After 18 hr treatment, all herbicide treatment inhibited cell division significantly. After 24 hr treatment almost 100% inhibition of cell division occurred at 1 x 10(-4)M to 1 x 10(-3)M while 20% inhibition of cell division occurred at 1 x 10(-6)M concentration at same exposure period
