A couple questions.

We try to spray our drainage ditch banks while crops are growing, if we can get to them. Normally we use a Gator with a sprayer, or a converted JD6000 hi-boy that no longer has booms....just a full span walking platform for someone to operate a hand boom from. We most often use either 2,4-d or some brush killer (which are usually 2,4-d based products).

First, does anyone know if there area aerial labels for 2-4,d or brush killer. This would be in the St of IL which may be different.

Second, have any of  you drone sprayers done this type of work yet? If so, do you hand-fly the drone or how do you pre-program it to follow a ditch that does a lot of winding around?

Would a drone sprayer be practical for this type of work? How would they charge for the work? By the hour?
