Jim from Soquel, Ca writes,
Can Armada fungicide be used advanced powdery mildew on a apple tree?
Oil sprays with added copper have been ineffective. (Gravensteins are apparently more prone to powdery mildew than other varities.)
Armada is labeled for powdery mildew and it is labeled for use on Apple Trees. However it is labeled for use on non-bearing apple trees so it cannot be used if you are harvesting.
