The tree has already bloomed. Can I still use Liquide Cop, and what Mix ratio?
Per the Monterey Liqui-Cop Product Label: When treating peaches for leaf curl, use 4-6 teaspoons per gallon of water. "Apply as a dormant or delayed dormant* spray to protect buds and shoots during the rainy period. Reapply up until late bud swell. Do not apply at less than 7-day intervals. Do not apply after full bloom"
According to several university studies and articles such as Peach Leaf Curl Management by the University of California, treatments are most effective in the winter dormant months between November and January, depending on region.
