Monterey Liqui-Cop is labeled to control fireblight on apples. Labeled instructions are: Apply at 10% bloom and repeat at no less than 5 – 7 day intervals during the bloom period for lower rates. For higher rates: Apply once as a full cover spray between silver-tip and greentip. Do not apply when green-tip reaches ½ inch as injuries may occur Do not use on copper sensitive varieties
