Weed Control in Field Crops - Soybean

Effect of soil residual on weed spectrum at postemergence timing.

page 299

Young, B. G., Matthews, J. L.

Objective:
This study was designed to determine any difference in weed spectrum from several soil residual herbicides at a postemergence application of glyphosate and to determine if the performance of glyphosate is different in response to the soil applied herbicides.
