• Fields with dense weed populations should probably be• Fields with dense weed populations should probably be avoided when possible.
• Preemergence herbicides are a necessity, timing of g y, gconventional postemergence herbicides is critical (i.e., they won’t kill big weeds).
M k f f i i l• Make sure of your reasons for growing conventional soybeans, not because the popular press says it MAY be a cheaper endeavor. Pencil your own seed costs/herbicide
d f lfprograms out and see for yourself.
• Don’t skimp on the weed management program in conventional soybeans There are few if any “rescue”conventional soybeans. There are few, if any, rescue options.
