You can stump spray or spray from 18" and down all the way around the trunk with a mix of Triclopyr (Remedy, etc) and diesel. Smooth bark can be as low as 15% triclopyr and 85% diesel and rougher bark needs to be upwards of 25% triclopyr. This can be done at any time of the year.
Timing is key when spraying the leaves and do not use diesel as it will burn the leaves off before it absorbs the chemical. Mix it with water and triclopyr, I believe that is 1% but isn't as effective.
Now is about the time to spray the leaves but with the droughty conditions, the leaf spray isn't the best method.
