In the above pictures, you should be able to see the size of both the soybeans and the weeds approximately 21 days after planting. The photo on the right is approximately 48 hours after the field was sprayed the first time with our Liberty herbicide program.
This particular field had been conventionally tilled and planted, but no pre-emerge herbicide had been applied. The next picture will show a strip that the sprayer missed with the first application. Yes, those weeds are taller than the soybeans.
So what do we need to take away from this? Even if a field is completely clean (conventional tilled or no till) weeds will get a foot hold very quickly, and if they are not managed in a timely manner, you will be trying to control them all season.
We have some recommendations to help have clean fields all season long:
• Make sure you start with a clean field
• Use a residual herbicide (maybe even two with different modes of action) preplant
