I have a new flush of giant rag weeds in roundup ready corn. The corn is 5 to 6 feet tall and the weeds are 2 feet tall and growing fast because of a lot of rain. Can I use drops and spray roundup or Distinct or 2-4D. I sprayed a quart of roundup when the corn was 18 inches tall. It will tassel in about a week.
