Abstract

These herbicides at rates of .01 to .25 lb/A caused moderate to severe morphological effects on soybeans and significant yield reductions. Soybeans treated in the vegetative stage were injured more than those treated in the bloom stage. The herbicide 2-(2,4,5-trichlorophenoxy)propionic acid (silvex) injured soybeans most followed by 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), 2,4-dichlorophenoxyacetic acid (2,4-D), and 4-(2,4-dichlorophenoxy)-butyric acid (2,4-DB), in that order.
