Can Stylet-Oil be used as a resistance management tool?
Absolutely. In fact we strongly urge growers to use the oil as the first treatment in a powdery mildew control program to eradicate resistant mildew strains before these strains are exposed to chemicals prone to resistance. Cleaning up an orchard or vineyard before the first DMI or strobilurin chemicals are applied is an excellent resistance management strategy. Stylet-Oil’s mode of action works at the physical level ― not the biochemical level ― thus the oil is an ideal material to alternate with DMI / strobilurin fungicides.
