Flowers from Melbourne, Fl writes
We are not aware of the Essentria IC3 Insecticide Concentrate causing phythophthroa and for best results, apply in cool weather, such as the early morning or late evening hours, but not in the heat of the day. Also, exceeding rates may create potential phytotoxicity on plant surfaces. Dilute with enough water to obtain thorough coverage.
