Effect of Growth Stage on Rice (Oryza sativa) Tolerance to Acifluorfen

  • Joe E. Street (a1) and Edward P. Richard (a2)


When applied at 0.1 or 0.3 kg/ha, acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} did not reduce rough rice (Oryza sativa L. ‘Labelle’) yield, milling yield, seed weight, seed germination, or plant height, regardless of growth stage. Application of 0.6 kg/ha to rice in the boot, late boot, or panicle filling stage reduced yields, but had no effect on plant height, seed germination, or whole milling yield.
