Its that time of year I like to focus on thinning the locust trees on my place. I have cut and sprayed, ringed and sprayed, sprayed foliar, and basal sprayed and finally figured out what works best for me. In winter I spray a mix of 25% Remedy and 75% diesel. Trees over 6" diameter, I like to ring them with a chainsaw and spray the cut. Under 6" diameter Basal spray the bottom foot or two of the tree. I prefer to use Remedy over Tordon as the Remedy does not stay in the soil and kill trees I want to keep. I use a gallon hand sprayer from Orscheln's. The diesel does not seem to eat it up and it is pretty cheap. In the spring when very small locusts start to leaf out, use a foliar spray with a mix of Remedy and 24D.
