Morningglory Identification

I posted this last year from UGA Weed Scientist Dr. Erick Prostko. There are many species of morninglory weeds to learn in the field. We have to make sure we have proper ID for control.

Why is this important? Not all morningglories are controlled equally by certain herbicides. Here are a few examples:

  • Gramoxone (paraquat) is generally good on most morningglory species but not smallflower. 
  • Basagran (bentazon) is generally not effective on most morningglory species but will control smallflower.
  • Staple (pyrithiobac) is generally considered to be an excellent morningglory herbicide but not on tall.
  • 2,4-DB is less effective on pitted morninglory than other species.
  • Aim (carfentrazone) is considered a good morningglory herbicide but not on smallflower.

Here are some photos of morninglory UGA Extension Weed Scientist Dr. Eric Prostko shared from LSU and Virginia Tech.
