I have Johnson grass growing on 400 yards of creek bank that is impossible to mow. Is there an un expensive sellective herbicide I can buy to target Johnson. I don't want to use roundup because it will lead to erosion of the bank.

Hello. Thank you for your question. Please contact the Daviess County Extension Horticulture Agent for assistance. I have included the contact information below.
In this situation, one possibility posed by the specialist is to use a rope wick on a hand applicator containing glyphosate and wipe or touch the Johnsongrass if the slope is not too steep to make this feasible.
Please call me at the contact information listed above if you have more questions.
You can all call me at 270-685-8480.
