Tom Wahl at Red Fern Farm told me his organic recipe that he states is the best control he’s come up with.
Dyna-gro neem oil 1 ounce to either a half ounce or 1 ounce of dish soap. If temps are cool use 1 ounce of dish soap. If warmer temperatures use 1/2 ounce dish soap. Dish soap being your surfactant.
Dyna-grow is 100% concentrated neem oil whereas others are 40% concentrate.
If you’re new to spraying, fill your tank with the necessary water first. Then, add the oil and dish soap. Put the lid on, shake your tank, and spray. It’s good to shake/agitate your tank as you go from tree to tree.
