If you were gonna pick a BUG spray for hunting camp apple trees would it be Bonide bug/ fungal spray, Sevin, or Malathion? I looked at all three at Home Depot. The Malathion listed Cherry, Apricot, Grapes, plums - No apple trees on the label. All were concentrates in the $14 to $18 range. Are they systemic - won't wash off in rain? I've read different things on these forums, but without digging back thru many threads, I thought it quicker to ask. Most are Liberty, Enterprise, Goldrush, Prairie Spy, Wolf River, Bonkers N.Y. 35. Thanks in advance.
