This is a picture I took when I was out spraying one of my corn fields. It was only six days after the frost. I would have liked to give the corn a few more days to recover but I knew these giant ragweed patches were there. The forecast was calling for rain for most of the next week and the giant ragweed can grow more than a foot in a week even if it is cold. How did I know the ragweed were there even without scouting?

BEANS WEEDY STRIP

This is a picture I took from the combine cab last fall. See the two strips of giant ragweeds? Apparently I had a nozzle that was plugged for two passes across the bean field. I knew that giant ragweed is a very prolific seed-producing weed and that there would be lots of giant ragweeds to deal with. This week I will scout the field to see if there are more giant ragweeds that germinated after I sprayed the field. If so, I will spray the corn field again. It will take a number of years to get the giant ragweed population under control.
