August 5, 2019: Still Plenty of Weed Control to Do

August 5, 2019

Chemical applications are all but over in this area and fungicide passes are starting to wind down.  It is wrong to think that right now there isn’t much to do except sit back and wait for harvest.  In fact, there is plenty we can do to finish up the season.  Now is a good time to get into the corn fields to see what hybrids are coming along the best and which ones may be lacking.  It is important to look for diseases in the corn that may require a late fungicide application.  It is also a good time to be looking at how the weed control worked in your fields.  It is easier to see problems at the ground level than it is from the cab of a combine. 

The state fair is right around the corner and we have all heard about state fair weeds.  If we start noticing weeds starting to pop up over our beans we need to start thinking about what we can do to not have that problem next year.  Using a full rate residual before planting and a full rate residual in crop is a must.  We also shouldn’t put too much faith in the new chemicals that are being used such as Dicamba and Enlist.  I have been in fields that dicamba was sprayed on 8-12” waterhemp that did not die.  It is important to follow the label and spray early to keep weeds in check.  The only good thing about finding weeds in your field this time of year as that we can learn from what happened and do a better job next season.
There is plenty to do while we wait for harvests and gathering information is one of the. SFG has some very good plots to get information from.  We have chemical, fungicide, nutrient and hybrid trials at our answer plot located just south of Knoxville.  If you would like a tour of the answer plot please let us know and we can make it happen.
