Any of those look good. As Barry said, oils have come a long way. I remember the old Volck Oil sold in Hawaii. That was some crude stuff that was worse than the insect in many cases. The new ultra refined light oils like Purespray Green and Whitmire UltraPure are great. I can use those on plants that could never be treated with the crude oils. Like roses in full leaf or other flowers.

Pressure burn and poor under leaf coverage is why I do not use adjustable tree guns on shrubs or flowers. The regulated ceramic disc-core nozzles on a double swivel wand operated at a set pressure do not allow a 0 degree stream to cut leaves and flowers.
