I had a food plot of wheat, turnips, and clover up and growing for one month. I checked it a week ago Sunday and it was the best looking plot that we planted this year. This Sunday there was nothing in the plot except for dirt and turnips. There wasn't even sign that something had been planted there. I have heard that this might have been done by armyworms. I live in Kansas and have never heard of such a thing? Any ideas on what happened?
