Making post-emergence spray applications allows you a great opportunity to visually see any areas of your crops that need special attention.
When I get a break from rain events, I take the time to write down notes on some of the problem spots I’ve identified in my fields. Make sure to accurately mark the problem area either by using GPS or stepping them off.
After I’ve completed harvest in the fall, I like to come back and treat the area. I post notes on my office bulletin board so I have easy, quick access to them. I have had great success at treating yellow-leafed corn as a result of potassium deficiencies even though results from grid samples claimed we had adequate levels of potassium.
Even with the lazy days of summer approaching, don’t be lazy when it comes to identifying potential problems that can be corrected and make you more profitable.
