We had some on one area of a 30 acre field.
Spot sprayed it in soybeans in 2023.
Went out soon after Harvest and pulled several 4 to 5 inch cane plants.
It had germinated with wet conditions near harvest time.
Then we sprayed Glyphosate with a drone on maybe 10 acres of the field in Corn the following year in 2024.
There was one clump in the soybeans last year.
It was in a wet spot where the beans were drowned out.
