Abstract

The soil activity of foliar-applied HOE 29152 {2-[4-trifluoromethyl-phenoxy)phenoxy] propanoic acid} and diclofop {2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid} on barnyardgrass [Echinochloa crus-galli (L.) Beauv.] and yellow foxtail [Setaria lutescens (Weigel) Hubb.] was evaluated in the greenhouse. HOE 29152 was applied at 0.1, 1.2, 2.4, and 3.5 kg/ha; and diclofop was applied at 0.5, 2.7, 4.9, and 7.2 kg/ha. Both compounds applied to roots or shoots before emergence reduced growth. Neither compound had much, if any, effect on the germination of barnyardgrass or yellow foxtail; however, the survival of both weed species that germinated in solutions of these two compounds was reduced. The number of seedlings surviving for both weed species was reduced by both compounds. Seedling survival from germination imbibition by diclofop and HOE 29152 was influenced by the presence of light at the time of seed germination.
